ES21 x ROTTMNT AU Masterpost:

Teenage Mutant Mystic DEMONS

a.k.a: TMMDemons AU

Trigger Warnings: death, child trafficking, demonic rituals, ghosts, dehumanization, human experimentation, child abuse, demons, mentions of cults Characters: Sena, Hiruma, Kurita, Musashi, Doburoku

SUMMARY:

Child trafficking is the one thing that brings Sena, Hiruma, Kurita, and Musashi together.

Sena and the Maou Trio (who i will now be referring to as "the four kids") are four of the hundreds of children who were kidnapped by traffickers, and sold to an organization led by a cult.

The facility, known as "Deimon," is located in a forest within the countryside. This organization buys trafficked kids, and uses them for human experiments. And of their dozens of experiments, only two bear fruit: "Project Maou," and "Project Ghost."

Project Maou is the organization's main experiment. The cult leading the organization has one main goal: to summon the king of demons, should it truly exist. And to do that, the experiment's aim is to use mystic energy to insert the soul of the demon king into a child, to make the child easy to control and influence.

And of the kids, Hiruma, Kurita, and Musashi are the three most promising subjects of Project Maou.

Sena, meanwhile, is the sole survivor of the succesful Project Ghost. This experiment was far simpler than Project Maou. Its aim was simple: to give a human child the abilities of ghosts. This experiment was a pioneer project, which paved the way for Project Maou.

The last stage of Project Maou is a ritual; an attempt to summon the king of demons unto this human plane. Kurita, Hiruma, and Musashi are dragged into the middle of a summoning circle.

An hour into the ritual, something goes wrong. Due to miscalculations in the amount of mystic energy, the demon king's soul splinters into pieces, and some fragments of his soul embed themselves onto the three screaming children.

The ritual fails. The whole area explodes, and decimates all life within a one-mile radius.

Everything is gone. The the scientists and staff are all reduced to ash. The buildings, trees, plant life, and animal life have all become nothing but dust. And all that remains is scorched earth.

Nothing is left. Nothing—except for four genetically enhanced children, who crawl out of the rubble after regaining consciousness.

The Maou Trio now find themselves with newly-mutated bodies. Bat wings, clawed hands and feet, markings, tails, and horns.

Sena looks different from the other three. He does not have those physical traits, which sometimes makes him feel like he's not one of them.

The kids venture out of the forest, and meet Doburoku, a yokai hermit who lives on the outskirts of a town.

Eventually, Doburoku adopts the little rascals. And after years of companionship, they come to see each other as a family.

As a yokai, Doburoku has mystic powers. Upon learning that the kids actually possess mystic energy, he starts teaching the four kids how to use their mystic powers.

CHARACTER SHEETS:

SENA • HIRUMA • KURITA • MUSASHI • DOBUROKU SAKAKI (coming soon)

Maou Trio

MEMES:

• Every Found Family's got...

• Snitches get stitches

NOTE: In this AU, the Sena & the Maou trio are raised together under one roof, like siblings. As a result, the kids are more playful, and they sometimes have rivalries with one another. They trust each other, and they are physically affectionate with one another. As such, it's common to see Hiruma hugging Sena, or even Musashi sleeping on Kurita's back. This AU is just a lotta Maou Trio + Sena puppy-piling on each other to cope with trauma.

Teenage Mutant Mystic DEMONS AU (TMMDemons AU)

HIRUMA YOUICHI

[ Subject MAOU-001, The Leader, One of the Eldest Twins ]

Nonbinary mutant demon.

Pronouns: They/Them.

Since they're an orphan, the only name they have in the government records is "Youichi." They don't actually have a last name, so in the years when they suffered experimentation, one of the only things that kept them sane was the mental activity of making a surname for themself. And they chose: "Hiruma."

Scientists in the Deimon facility dubbed Hiruma as "Subject MAOU-001."

In this AU, Hiruma is more playful, as a result of growing up alongside Sena, Kurita, and Musashi as siblings. They are also more open to their siblings, but more wary of strangers. Hiruma becomes the voice of reason whenever their siblings meet someone new, as they caution the others to be wary and observant of new people. The four have already suffered through dehumanizing experimentation and human trafficking. It's better to play it safe, than to suffer the consequences of betrayal and ignorance.

Hiruma has long, sharp spikes on their shoulders and arms, and shorter spikes on their spine. The red markings on their arms are rectangular, almost shaped like pixels and guns.

The skin on their limbs, once pale when they were still human, is now a color so dark, that it's even blacker than night. Red markings shaped like diamonds strung together are what separate the color of Hiruma's limbs from the color of their torso. All the Maou trio have these specific features.

Hiruma's eyes glow red. They have markings of a large, upside-down cross on their chest. Their genitals are hidden within a slit in their crotch area (like turtle cloacas).

They have sharp claws. So sharp that they've accidentally popped or stabbed through objects on more than one occassion.

All of the Maou trio have tails. Hiruma has three red-and-gold tails that are all tipped with eyes. Hiruma uses these eyes as both weapons, and as video recorders. Which means they're recording everything around them at all times.

Hiruma's hair is literally made out of fire. It never dies out.

Musashi and Kurita have horns, while Hiruma doesn't. Hiruma's dead jealous; if they had horns, they would decorate their horns with jewelry. To compensate, Hiruma adorns Musashi's and Kurita's horns with jewelry during special days.

Hiruma is often clothed in red, as it is their favorite color.

When the kids were younger, Hiruma dubbed themself as "The Leader." They usually take charge, along with Musashi. Hiruma and Musashi both look after Kurita and Sena, the younger ones, together.

Hiruma is known by different names. In public, their siblings call them "Hiruma." Hiruma doesn't want strangers knowing their birth name.

When in the comfort of their home, their siblings call them, "Youichi," or "Ichii," when the others are feeling playful.

Doburoku calls them, "Yo-Yo," to Hiruma's chagrin. Although when the situation is serious, he calls them, "Youichi." When Hiruma has cooked up some trouble and Doburoku is pissed off, he calls his kids by their full names.

Of the four kids, Hiruma is one of the two eldest. (Musashi is the other eldest sibling).

Hiruma and Musashi were raised in different orphanages. The two know they were born on the same year, but don't know their own dates of birth.

A year after Doburoku adopted the kids, Kurita had once suggested jokingly that Hiruma and Musashi were "practically twins." At first, the two were both adamant that it was impossible. But then, they grew to love the idea of having a twinship.

Hence, when the others refer to the Musashi-Hiruma duo, they often refer to them as "the twins."

Hiruma likes watching yakuza movies, so the way they speak makes it sound like they're a criminal.

Hiruma's a gunsmith and a weaponsmith. At first, before they developed their mystic powers, they built guns as a hobby. They also have a fascination of guns because they fear for their family's safety.

Hiruma is the one who illegally earns money for the family. They earn even more than Doburoku, the only adult in the family. And to do that, Hiruma hacks ATM's and has several ATM cards connected to billionaires' accounts.

Which means Hiruma is literally stealing from billionaires to fund their family. They buy furniture for the home, raw materials for Musashi, games and anime merch for Sena, and ingredients and cooking utensils for Kurita.

Hiruma also hacks into government servers and CCTV systems for fun, and pirates films and shows for their family to watch. They also record everything, to their siblings' chagrin.

Hiruma was inspired by watching their favorite movie, Megamind. As such, Hiruma cares very much about "Presentation." So, when getting into fights, Hiruma loves to intimidate their enemies by showing the first level of what they call their "Disposal Unit." In battles, this is how Hiruma usually presents themself:

The first wave of Hiruma's Disposal Unit, or what they call, "Category 1," is only meant to incapacitate a few opponents.

"Category 2," or the second wave, is meant to incapacitate a several groups of opponents.

The third wave, or "Category 3," is meant to kill a few opponents.

"Category 4," is meant to massacre a wholeass army.

Currently, Hiruma is working on "Category 5," a nuclear bomb that will annihalate supernatural deities or even aliens. After all, Hiruma thinks, they can't be too lax on security. Better to be overprepared than to lose their family by being underprepared for a big crisis.

Hiruma also expands to making more complicated artillery. The type that starts out looking like normal objects, before turning into complex guns. For example, they build a briefcase that transforms into a machine gun, after watching this anime scene with Sena:

Hiruma makes an artillery-bag for all their family members, just as a failsafe. Whenever the four siblings go out, they always bring one of Hiruma's briefcases, just in case.

Inspired by watching Sena's gameplay, Hiruma loves building intimidating and powerful artillery like this:

Out of their four siblings, Hiruma has the messiest room. They can't be bothered to clean, not when their brain is fueling them ideas faster than they can make artillery.

Hiruma has their own workshop/laboratory, which is right beside their room. They call their lab, "My Evil Lair," because they're a dork who loves the villain aesthetic.

Hiruma also created and installed cameras around their home's area. They also constantly monitor the CCTV footage, and get notified by their systems immediately when something unusal is happening. Their family may live in a hermit's house in the middle of nowhere, but it's better to be safe than sorry.

Hiruma loves wearing dresses and skirts at home, because fuck gender norms. When they go out to roam the city, they prefer wearing pants, just in case they need to fight.

Hiruma's love for skirts and dresses influenced their siblings, and soon, the others started wearing them too. The Maou trio's favorite are mini-skirts and backless dresses, because it gives their tails or their wings free reign.

And of course, Hiruma loves make-up. They love putting on red and black eyeliner, and doing their eyebrows. Hiruma hates lip products because they often get lipstick on their fangs and teeth. It's pretty inconvenient for them.

Hiruma also loves painting the claws on their hands and feet red, though the paint often chips off due to Hiruma's constant work.

HIRUMA'S MYSTIC POWERS:

All three of the Maou trio can create energy constructs. Hiruma's energy constructs, however, are different from Kurita's and Musashi's own constructs.

Hiruma's mystic powers are all about creating red, semi-transparent constructs of guns and artillery, made out of their mystic energy. It looks like this:

The gun constructs they conjure vary in size, as it takes great mastery, concentration, and mystic energy to create constructs bigger than their own body.

Hiruma finds their mystic powers very convenient, despite the cost of being drained to exhaustion. They know how long projects can take, and how much determination it takes to finish one, so they like the speed with which their mystic guns appear.

After watching a few episodes of RWBY with Sena, Hiruma starts conjuring mystic nunchuck-guns for close combat after seeing this coolass scene:

When it comes to making technology, Hiruma has to collaborate with Musashi to make various rockets. The whole process takes time. So when Hiruma discovers that they can bend the physical manifestations of their mystic energy to make anything they desire, they make these for their convenience:

Hiruma loves making combo moves with their siblings. Sena's portals make Hiruma's artillery unpredictable, as Sena can ensure that Hiruma's energy construct bullets reach the enemy faster.

Musashi's transmutation constructs can prove as convenient surfaces to spawn Hiruma's own gun constructs.

Kurita's bodily energy construct is a gigantic moving warrior that Hiruma can propel in the air with their rocket constructs. Mystic energy makes anything possible.

Hiruma also loves being flashy, so that the enemies' eyes are on them. This ensures that their siblings are a little safer, as long as Hiruma keeps their opponents distracted. Thus, it's not uncommon to see Hiruma doing this:

Hiruma tries to act as if they're "emotionally unavailable" in public. And yet ironically, Hiruma's mystic energy is heavily influenced by their emotions. When they're feeling manic with energy, their mystic artillery is as lively as they are. But when Hiruma is truly scared, even when they try not to show it, their mystic artillery shows it by glitching, or sometimes even fizzling out into nothingness.

Hiruma is the second person to awaken their mystic powers, right after Kurita did. It was Hiruma's desire to protect their brothers that awakened their power.

Teenage Mutant Mystic DEMONS AU

(TMMDemons AU)

MUSASHI

[ Subject MAOU-011. The Powerhouse. One of the eldest twins. ]

Transmasc.

Pronouns: He/Him.

Demon mutant. Half-demon, half-human.

Mutated from a cult organization's human experiment, called Project Maou.

One of the eldest twins. (The other one is Hiruma).

Musashi's father Hanzaemon worked in his construction. Hanzaemon's team all tragically died in a construction accident. As Musashi had no other parent, as his father was single, Musashi was then sent to an orphanage.

Kidnapped by traffickers while he was walking home alone from school. Since Musashi was just a kid, he could not overpower his abductors.

He loathes his deadname, so he just goes by the name "Musashi." He picked that name because he admires Miyamoto Musashi, the most revered and celebrated swordsman in Japanese history.

Kurita and Hiruma call him by that name, while Sena calls him, "Musashi-nii," or "Musashi-niisan."

Musashi often collaborates with Hiruma to make holographic screens for their family's shared use. Hiruma makes the trackers, and Musashi makes the tech.

He's the engineer / mechanic / builder of the family. His interest in construction stems from his desire to continue his late father's legacy, and to provide for his new found family.

As Musashi's legs are strong, he often kicks his weapons, like this:

"Musashi usually takes charge, along with Hiruma. They both look after Kurita and Sena, the younger ones, together." (Taken from Hiruma's Character Sheet)

As a result, both Hiruma and Musashi have somewhat developed "Eldest Child Syndrome," as sometimes, Doburoku is too drunk or depressed to look after them.

This version of Musashi is more proactive in taking charge, especially when Hiruma is feeling silly (and itching for property damage).

Musashi has spikes on his knees. His feet are clawed, and he has flaming hair and horns. (Hiruma is dead jealous of the horns.)

He has three tails, just like Kurita and Hiruma. However, Musashi's tails are black spider legs that are tipped with sharp claws. These extra legs can lift him off the ground so that the rest of his body looks like it's floating. It looks like this:

Like the other members of the Maou trio, Musashi also has markings of a giant cross on his chest.

His spider-leg tails can morph into actual, gigantic wings that are powerful enough to make him fly.

Musashi's fighting style utilizes his legs, just like Sena. However, Musashi's style is different from Sena's in that Musashi relies on (you guessed it) the strength of his kicks.

Musashi's quite similar to Sena when it comes to their feet. Musashi's feet are constantly covered in hellfire. Sena's feet, meanwhile, are constantly covered in ghost fire.

(Yes, their feet glow in the dark. Yes, they find it inconvenient when trying to hide in the dark.)

Musashi can also use his spider-leg tails to launch heavy objects at enemies, and they also function as extra hands—that are really sharp.

When Musashi isn't in battle, he fits the tips of his tails with hand prosthetics so that he doesn't accidentally injure his siblings.

Two years after the four kids' adoption, Musashi's body dysphoria started getting harder and harder to ignore. So with Hiruma's help in the area of research, Musashi set up a sacrificial ritual. In exchange for Musashi's body parts (he very happily sacrifices his breasts and ovaries), his own mystic powers will morph into something different—something more powerful. (Yes I am projecting my hopes and dreams here. Musashi is really out here living the Trans Dream.)

What Musashi doesn't know is that the ritual was absolutely hellish to witness. Thinking he was alone, he activated the ritual himself. Musashi didn't know that Hiruma was watching from afar. Even when unconsciousness took Musashi, he thought he was the only person in the area.

Musashi was still unconscious when Hiruma quickly called Kurita and Sena over for backup, and Musashi was still down under when his three siblinga horrifically saw that parts of Musashi's body—more specifically, parts of his chest and womb—were disintegrating. They watched as the skin sealed itself back together with markings, and they watched as Musashi crackled with newfound power that surged within him, even as he lay unconscious.

When Musashi woke up after the ritual, he found that one of his eyes was now a different color. Completely black, instead of demon-red. He also noticed that he now has additional, diamond-shaped markings on his chest, as a result of sacrificing his breasts. It's reminiscent of top surgery scars. Plus, he has a scar on his womb as well. He and his siblings find these new changes on his appearance cool as fuck.

Although, the consequences of witnessing the ritual were heavy on Musashi's siblings, who have become more protective of him as a result.

Among other things, researching on the materials for the ritual also sparked Musashi's interest in chemical engineering. It's something that he and Hiruma bond over, besides mechanics.

Musashi tends to lean towards civil engineering, as he wants to study infrastructure in honor of his late father. Hiruma, meanwhile, leans more towards ballistics, which is the science of projectiles and firearms. Although, the two work together when it comes to soldering, metallurgy, and reverse engineering.

MUSASHI'S MYSTIC POWERS

Transmutation. (Get it? Because he's trans? Eyyy) This includes the construction and deconstruction of objects.

These mystic powers are the result of Musashi's and Hiruma's sacrificial ritual. Musashi's original mystic powers will now forever be a mystery, as the ritual has morphed his powers into transmutation instead.

Musashi's mystic powers were actually dormant before the ritual, so he will never know what his original powers would look or feel like. It doesn't really bother him, though. The gender ecstasy is worth it, babyyyyy

Musashi is the only one most in-sync with the element of earth, because of his interest in construction and metals.

As a result, his mystic powers are a manifestation of his desire to create things. With only intent, he can create a summoning circle when his skin touches an object. And instantly, with a flash of light, the object breaks down, and contorts itself into the shape Musashi desires. Like so:

Musashi can also use his spider-leg tails to transmute objects.

This can also be used in battle. As long as Musashi is close to an object, he can transmute it into something else.

With this power, Musashi crafts his siblings' weapons out of high-grade titanium. If ever his siblings run out of weapons on the battlefield, he can just transmute them new ones. And with Sena's help in teleportation, the weapons can be delivered to the others in a blink.

Musashi is even more dangerous on land, because he can destroy the whole terrain by doing shit like this:

Even with only scraps and debris at his disposal, Musashi can create dangerous weapons

Musashi can transmute his weapons into different things, even when he is mid-combat. He could be wielding a scythe, and then in a flash of light, he'd be holding a katana. And in another flash of light, he could turn it into a spear.

He loves transmuting his current weapon into either a pair of twin katanas, or a big, cross-shaped spear that he can kick.

He also has a knack for using chained weapons in combat. He infuses these weapons with hellfire when his foot makes contact with the weapon, and kicks them toward his opponents.

Musashi also finds out only much later that with his summoning circles, he can also create a portal—something which everyone, including Musashi, thought only Sena could do.

Musashi's ritual rendered him the most powerful of his siblings. This is why Hiruma calls him, "The Powerhouse." It's both an intimidation tactic, and a fact. Musashi can keep using his mystic powers long after his siblings have exhausted themselves.

This mystic power is also the reason why Musashi can easily renovate their family home to his family members' tastes.

Teenage Mutant Mystic DEMONS AU (TMMDemons AU)

KURITA RYOUKAN

[ Subject MAOU-077. The Titan. The Tank. Middle Sibling. ]

Nonbinary.

Pronouns: She/Her.

Demon Mutant. Half-human, half-demon.

Product of the human experiment, "Project Maou."

Middle Sibling / Second Youngest Sibling.

Scientists in the Deimon facility dubbed Kurita as "Subject MAOU-077."

The only parts of Kurita's body that keep her original skin color are her hands and her head. Her legs, arms, and back, meanwhile, are now a color so dark, that it's even blacker than night.

Kurita's eyes glow red. She has markings of a large, upside-down cross on her chest. On her arms, she also has markings that look like a satanic circle, an acorn, and a star, all intersected by one long line. Her genitals are hidden within a slit in their crotch area (like turtle cloacas). Her hair is literally made out of fire. It never dies out. She also has three tails. All the Maou trio have these specific features.

Kurita's three tails are three additional arms, colored red and gold.

Kurita has four more arms on her upper back. They can transform into demon wings that are strong enough to carry Kurita and her siblings.

So, in total, Kurita has nine arms. Her seven extra arms don't have joints, so they move around like tentacles.

Her four extra arms on her back have the ability to multiply.

She usually makes use of her extra arms to pull her siblings out of danger, or to hold back Hiruma from committing homicide. It basically looks like a mass of tentacles tipped with claws, dragging the selected target towards Kurita, like so:

Kurita's fears are all centered around her accidentally hurting people, especially her siblings.

She also has sharp, clawed feet that can puncture the ground for further stability. She also has long horns on her head, which Hiruma is dead jealous of.

Sena, Musashi, and Hiruma also use Kurita as a jungle gym, more often than not. It's common to see them climbing up her back, or perching themselves on her shoulders. Kurita is of course, strong enough to carry all her siblings. When she and her siblings are in danger, her number one instinct is to grab all the others and shield them.

She is the number one heavy hitter of the team, and she deals critical hits in one move. This is why Hiruma gives her the nickname, "The Titan," to scare off their opponents.

Kurita loves cooking. She is the chef of the family, and she takes pride in her cooking. Because she's a demon, her spice tolerance is off the charts. The same is true for Hiruma and Musashi. Thus, when Kurita cooks something spicy, she makes sure to be mindful of dialling down on the spice, for Sena's and Doburoku's sakes.

Despite her battle prowess, she is very content to just farm in the fields. When cooking, she puts aside the food waste to be used for fertilizer. Her extra arms are quite handy (LMAO) when it comes to cooking. Anyone who enters the kitchen will see Kurita's extra arms zooming about, busily chopping, putting aside food waste, stirring, and taking ingredients from the cabinets.

Kurita loves bonding with Sena over cooking videos. They love watching Youtubers like Liziqi, or Tiktok channels like The Glam Kitchen.

When Kurita's free, she helps out in either Musashi's workshop, or Hiruma's "Evil Lair." She usually lugs around heavy machinery, so her siblings don't have to strain themselves.

Once a week, Kurita also accompanies Hiruma and Musashi to junkyards for spare parts.

Out of her siblings, she loves training the most. This is also why she has the best stamina among the four. Kurita spends the most time with Doburoku, because she never tires of learning new techniques, both in farming and in combat.

(She is actually Doburoku's favorite kid, but he won't ever tell a soul.)

When Kurita was young, she ran away from her abusive home. Being a little kid, she unknowingly ran into traffickers who took her from the streets, and sold her to a cult organization.

Though she associates bad memories with her birth name, Kurita Ryoukan, she does not want her tragic background to take that from her too. She holds onto that name with a vice-like grip in the hopes that someday, she will learn to love it.

And with the way her siblings fix all the cracks in her heart, she learns to see that she is, in fact, learning to love her name, because she loves the way her family says it. With affection, with devotion, and with love.

Food is the one thing that Kurita associates with love, especially because she wants her family to eat well. Kurita, in particular, was starved when she was still in the hands of the traffickers, which is why she always makes sure to eat a lot.

She loves it when her siblings climb onto her shoulders, because she adores the physical touch, and the amount of trust they put into her to hold them up.

Within the family, she gives the best hugs, because her extra arms will envelop the other person too, and make the hug extra warm!

She is a cinnamon roll who is also not afraid to fuck people up. Growing up with Hiruma and a morally ambiguous Sena means that this version of Kurita is more unhinged as well.

KURITA'S MYSTIC POWERS:

Kurita is the first among her siblings to awaken her mystic powers.

Along with Hiruma and Musashi, Kurita also has the ability to manifest mystic energy constructs.

Kurita's energy constructs manifest in the shape of her body. She can alter the construct in its entirety to giant sizes.

Kurita can also independently alter the size of its appendages to take down physically large or exceptionally powerful opponents.

She can add additional limbs to his construct, and form a more traditional energetic shield to block attacks.

Kurita's siblings can also enter her construct. She can shield them within the construct, or combine their moves with hers, like so:

In a way, Kurita's construct is like a mech, without needing the actual technological components.

Kurita's energy constructs can also grow several tentacle-like arms with clawed hands. It makes her even more dangerous in battle. Hiruma once compared her to Jaegers from the movie, "Pacific Rim."

When one of the four siblings fall unconscious mid-air, Kurita is the one who rushes to catch them.

Even if Kurita's construct crashes to the ground, the energy coating her acts as a shield, ensuring she and her companions within the construct are safe.

Kurita can also make clones that look just like her, even if they are energy constructs. When fatally harmed, only then do the clones reveal that they are only made of mystic energy, as they glitch, then fizzle into nothingness.

Kurita's energy constructs, combined with her siblings' powers, make several creative combo moves.

For example, when Kurita's gigantic energy construct is mid-punch, Sena can make a portal so that Kurita can punch an enemy who is quite a distance away. Hiruma can manifest guns that are attached to Kurita's construct, turning it into a gigantic mech that is armed to the teeth with artillery. Musashi can use Kurita's construct as a surface for his transmutations.

Teenage Mutant Mystic DEMONS AU

(TMMDemons AU)

SENA

[ Subject SN-21. The Ghost. The Wraith. Baby Sibling ]

Agender. Listen, it's hard for him to perceive gender when it's a human social construct, and he was raised out of human society.

Pronouns: He/She/They.

Ghost Mutant: half-mortal, half ghost. The product and sole survivor of the successful human experiment, "Project Ghost."

The youngest among the four kids, and also the shortest. The Maou trio sometimes refer to him as "Baby Sibling," even when he's just a year or two younger than them.

Sena was taken from his parents when he was but an infant. He grew up in the Deimon facility, and was basically raised by the scientists who experimented on him.

Because of this, Sena never truly had a name before Doburoku adopted him and the others. The scientists only ever called him, "Subject SN-21."

It was the Maou trio who started suggesting names for Sena, after their adoption.

Hiruma kept suggesting ridiculous names like "Ghost" or "Wraith" or "Chibi."

Kurita and Musashi, however, were the ones who successfully coined the name, "Sena," as the boy was still attached to his subject name, SN-21.

Hiruma (they/them), feeling petulant that no one picked their suggestions, started calling Sena the nicknames thay they came up with anyway. When Hiruma wants to intimidate the opponent, they call Sena either "Ghost" or "Wraith."

But usually, Hiruma just calls him, "Chibi." It's Hiruma's special nickname for him, because Sena is the youngest among them. Sometimes, Hiruma likes playing around with the letters of Sena's name, and making him new nicknames.

Hiruma has called Sena: "Lil Nas X," because it has the letters S-N-A. They've called Sena other nicknames like: Onsen (hot springs), Senichi, Five Sen (an ancient banknote), Senshi (soldier), Senzo, Kaisen (fight/battle/war), Senmatsu, and even Sen no Sen (to attack your opponent before they initiate the attack they've decided on.) Hiruma thinks it's funny, and Sena doesn't really mind the nicknames.

Unlike the Maou trio, Sena never actually got to experience the ups and downs of human society.

So the Maou trio and Doburoku take him to the closest city from time to time, just to show Sena what human society looks like. They make sure he tries even the most mundane of things to give him the full experience.

The first time Sena tried pizza, his eyes lit up like stars at the taste. The scientists only ever gave him bland foods at the Deimon facility (feeding hundreds of trafficked children was expensive). Because of that, Doburoku and the Maou trio make it a contest to feed Sena different types of pizza, hoping to find his favorite flavor.

Sena doesn't have a favorite flavor of pizza, though it has come to be his favorite food. And pizza has only become his favorite food because it's party size. He loves it because he can share it with others, and because it's delicious!

Sena is often forgetful because of his trauma. He doesn't remember most of his childhood (his brain is trying to protect him to cope) but he does remember the times when the experimentation hurt the most. And sometimes, he wakes up screaming, or wakes up in the midst of a panic attack.

Because of this, the Maou trio do what Dokuroku calls a "Demon Pile." The Maou trio all sort of puppy pile onto Sena, engulfing him in comfort and safety. Doburoku makes hot chocolate of everyone, and plays some comedy movies on TV.

When Sena is toeing the line between wakefulness and sleep, that is when he is the most honest. He whispers, "Love you guys," right before he falls asleep. The Maou trio, with their enhanced hearing, will always hear it. It never fails to make their hearts squeeze.

Because Sena's the youngest, he also has the "baby sibling privileges," so to speak. (Not that he knew what that truly is, because he was raised in a metaphorical media & culture vacuum.) Sena doesn't often ask for things, so when he does, the others would practically serve him the moon on a silver platter.

Hiruma would burn down civilizations for him. Musashi, the mechanic and engineer of the family, would practically build Sena the Tower of Babel, if he asked. Kurita would crush armies for him.

Sena returns this affection with his whole being. Not really knowing what "morals" are, he would do anything for the Maou trio as well.

Sena, without his own knowledge, sometimes becomes the most brutal of his siblings when it comes to battles. More so when one of his siblings get injured, which is the one thing that angers him.

Sena rarely gets angry, even when strangers push him around. This is an effect of the scientists dehumanizing him during his childhood. The constant abuse made him think it was normal to suffer.

To combat this way of thinking, the Maou trio and Doburoku have to drill it into Sena's brain again and again: "You do not deserve to feel suffering and pain. You must not endure abuse. You must fight back, and fight for yourself."

Out of all of them, Sena has a bad habit of self-sacrifice. Having a low to non-existent sense of self-worth, he would endure even the greatest of pain for his siblings. This makes him the most predictable in battle, because when he sees one of his family about to fall into mortal danger, Sena always uses his powers to switch places with them to take the blow instead.

This is a pain in the ass, as the Maou trio care for him goddamn it, and don't want him getting hurt just to protect them. Hiruma and Musashi, being the inventors and fixers within the family, try to come up with inventions and ways to stop Sena mid-act. Kurita (she/her), as the tank, trains herself to be faster and stronger, so that she can stop Sena, and so that she can take harsher blows, to protect her siblings.

Sena started loving videogames an anime, ever since Doburoku started bringing home some games and anime DVDs from the city.

The knowledge from anime and videogames proves beneficial for the kids. Sena shows the others things he thinks they might like, from the anime and games.

He shows them cool moves he thinks they can execute as a team or individually. Battle formations, combo moves, and even sneak attacks.

As the strategist of the family, Hiruma (they/them) loves it when Sena shows them a new move he saw in a game or anime. And as the gunsmith and weaponsmith of the family, Hiruma always pay attention when Sena shows them a weapon that he thinks Hiruma would like. Rocket launchers, flamethrowers, guns, artillery, and even drones—whenever Sena shows them these, Hiruma would stop whatever they're doing just to watch.

Musashi always pays attention whenever Sena shows him a cool invention he saw from the futuristic and steampunk anime and games. Since Sena knows Musashi wants to improve their standard of living to the best of their abilities, he never fails to send screenshots and recordings whenever he sees Musashi interested in a specific fictional concept he found.

Sena sends Kurita (she/her) food from his anime and games, because he knows Kurita loves the challenge of creating a recipe, merely from a dish's final product.

Once Doburoku introduces Sena to Youtube, it becomes his primary source of information. That's where he starts actually learning about human society, and how humans act.

The family often learn Youtube terms and memes from Sena. Sometimes, Sena seems to be speaking another language entirely when he starts spouting videogame terms, or things like, "Skill issue," or "For real for real," or "L + Ratio." He's often the one to teach them what these terms mean, and Hiruma (they/them) always listens so that they can add to their vocabulary to roast their opponents better.

Because Sena was raised alongside Hiruma, this version of Sena is more playful, more willing to play pranks on his brothers. He is also less reserved and more open, as he trusts his siblings with everything.

Sena is also the most honest of his siblings. He has a hard time lying, because he has no practice. This is exactly why Doburoku, their adoptive parent, tends to always ask Sena first when he and his siblings get in trouble. As such, scenes like this one are common:

DOBUROKU: Sena, what's the matter?

SENA: [sweating bullets, eyes roaming everywhere in panic] I... Uh... We...

HIRUMA: [under his breath] Don't you rat us out, fucking chibi.

DOBUROKU: [raising an eyebrow] Well, kid?

SENA: I—uh—guh... The truth is....

HIRUMA: [raising a frying pan] Snitches get stitches.

SENA: is....

KURITA: [grabs onto Hiruma, restraining them.] Hiruma, NO!!!

HIRUMA: [trying to wriggle free] Hiruma, YES!!!

MUSASHI: [softly bonks Hiruma's head] Stand down, idiot.

SENA: The truth...

DOBUROKU: Yes?

SENA: I.... I—I farted.

EVERYONE: [Dead silence.]

HIRUMA: [slowly lowers his frying pan]

DOBUROKU: Listen, if you're gonna lie, you have to try harder. But I commend your efforts, kid. [The smell of fart reaches his nose.] Oh, you weren't joking.

Sena has the cleanest room among his siblings. It amazes the others to no end.

Sena is actually extremely interested in farming, and in plants overall. Being raised in the confines of the Deimon facility, they only know white tiled floors and grey walls. They've only ever seen plants in their food. So among his siblings, he is the most ecstatic to join Doburoku in farming their own food.

Among the kids, Sena has had supernatural abilities the longest. Being the sole survivor of Project Ghost means he had ample time to get used to his abilities long before the Deimon facility exploded.

The scientists tested the fuck outta him, so even as child, he's familiar and quite in-tune with his ghost abilities.

SENA'S GHOST ABILITIES:

Sena can see spirits (as he is some sort of hybrid ghost as well), and can interact with them.

His default is that he floats a few inches off the ground. To look normal, he has to concentrate on making his feet touch the floor.

He has the ability to pass through people and objects, and if he so pleases, cause damage to those he passes through.

He can lunge forward in short distances, like so:

This ability also proves useful, as Sena technically breaks down his molecules into energy particles colored black and blue. He then reconstructs his body in a burst of light.

If he wants to cause damage to someone or something, the fight will look like this:

This is actually why Sena's main weapons are knives. Despite being easily terrified, Sena's Ghost Abilities are better for close combat.

Sena can also turn invisible. His favorite, non-lethal strategy is to disappear, and tie up his enemies while they can't see him. In this state, time moves slower for Sena, so he appears to be a dozen times faster than normal.

This ability proves useful, as Sena is an unstoppable force in this state. The probability of enemies interrupting this move is extremely low, as Sena becomes physically untouchable.

When Sena wants to do damage, this is what it will look like in Sena's POV, due to the light difference in time dilation:

To the outside eye, he looks like he's teleporting, but he truly is not. He just deconstructs his molecules, zooms towards a direction, and the reforms his body. He does, however, develop teleportation as a mystic power.

Sena can also disappear in a cloud of smoke. This usually happens when he's too terrified. Disappearing is a flight defense mechanism, reminiscent of turtles retreating into their shells.

However, when Sena dissipates into a cloud of smoke, he leaves his skull behind. It drops to the ground, unhindered by the confines of his semi-mortal form. This skull contains the essense of his soul, so the Maou trio take care of it when Sena dematerializes.

When Sena disappears while the four are fleeing from a terrifying enemy, the Maou trio scramble to snatch his skull into their hands, and then run.

SENA'S MYSTIC POWERS:

Sena's mystic power is the ability to teleport using portals and conduits. At first, Sena was extremely disappointed to find out about this. To the untrained eye, his ghost abilities already looked quite similar to teleportation.

But then, Sena found out that he could open portals that led to far-off places as well. This, the while family thought to be extremely convenient, as they could just portal from place to place.

He can also use portals in battle. He can launch himself and his brothers into portals, as a sneak attack. Like so:

He can also use objects as conduits, to teleport from one place to another. He litters his mystic energy onto objects or in the air, and then uses those as a sort of landing pad to reappear where he left his mystic energy. In the midst of combat, he mostly uses his knives, like this:

With Sena's ghost abilities and mystic powers, it is a fact that he is the fastest among them. So as a failsafe, the Maou trio allow him to scatter some of his mystic energy onto them, and onto their gear. This ensures that when one of the trio are in imminent danger, at least Sena can reach them.

Sena's mystic powers are a manifestation of his wish to travel all around the world, and his wish to protect his siblings. Sena knows he is far from Kurita's and Musashi's strength, and even farther from Hiruma's intelligence. So Sena settles for his speed; the one quality he can be relied on to possess.

After Sena stabilized his portalling mystic powers, he and the others started going to cities more often.

Learning from the ultimate prankmaster Hiruma, Sena also sometimes pranks the others. It's all ultimately harmless; sometimes, Sena would portal them somewhere a foot above the ground, so the others stumble a little when they fall.

Sometimes, Sena would portal his brothers to bump into each other when he's feeling playful.
