Hi I love love LOVE your blog would you maybe do all the obey me brothers x reader yandere wise?

Hi anon! Thank you for the love I really appreciate it!! I know I sound like a broken record, but I was so nervous to start this blog and I’m so happy that people are enjoying my writings. So this request was kinda vague (and it’s my first yandere request!), so I’m assuming you mean general headcannons being in a relationship with the brothers (separately) being yandere. If I’m wrong, just send in the request again with some more details and I’ll be happy to redo it. Reader is gender neutral and I hope you enjoy!

Sidenote: Beel’s and Belphie’s part is a little bit short. Sorry!

TW: Unhealthy relationships, toxic behavior, yandere behavior but not too graphic is mentioned

Spoilers for Lesson 9-11 (mentioned in Satan’s) and Lesson 16 (mentioned in Mammon’s, Beel’s and Belphie’s)

Yandere HC’s with The Bros

So let me begin by saying this: I think that all demons are very territorial and even more so possessive. The brothers no doubt all love you, but you couldn’t help but realize that their way of love was starting to get just a tad bit worrying. I mean, you knew that they were demons and that they wouldn’t dream of hurting you (again), but it was starting to feel...intense. After all, they were just starting to express openly how they feel. You tried to give them the benefit of the doubt, but it was scary. They were determined that you were going to know just how much they love you...

And you were going to accept it, whether you wanted to or not.

Lucifer

Very controlling

You thought he was strict before, please, you haven’t seen anything yet

It went from telling you when to eat to downright constantly being in his presence. You were pretty much living in his room at this point, with the exception of leaving for school where he was your only escort

He was the embodiment of Pride, he took in pride in everything that he does, which included you. He was the reflection of perfection, and he were going to make sure that you and your relationship with him would reflect that too

He couldn’t help it. He was the oldest and the brother in charge, and that control transferred into your relationship. There was no room for backtalk or disobedience with him, it was his word, and his word was final

But, it was coming from a good place (in his eyes). He only wanted the best for you, because you deserved the best. And you’re a human, one of the weakest beings to ever exist that demons wouldn’t hesitate to rip limb from limb for fun. And he already lost you once due to his negligence. If he was there, if he knew what you were up to, if he knew your every move, then it wouldn’t have taken place. If he takes control, you would be safe. Sure, you would complain about wanting your “freedom” back (relax MC, he didn’t lock you up yet), but this was the best course of action.

Being the Avatar of Pride and the oldest (and most powerful) of all the brothers, Lucifer was intimidating. He knew the power and the weight that his name holds in the Devildom, he wasn’t Diavolo’s right hand man for nothing. So with that being said, he didn’t have to worry about any lesser demon even thinking about trying to take you away.

He didn’t see anyone as competition. Psh, do you see who he is? If anything, he sees these “competitors” as nuisances. Annoyances that didn’t know how to go away when they noticed that they weren’t welcomed. They weren’t going to take you away, they won’t even get the chance to be physically close to you, but...

He didn’t have a problem in making an example out of one or two people, as a matter of fact he relished it in. Have them on display for the whole Devildom to see. After looking at their disfigured and nearly destroyed bodies, the message is made clear: to make sure that it’s known that you are off limits completely

He loves you MC, and you may not understand that when he hovers over you, demanding that you never leave his sight, when he makes it to where none of your friends talk to you anymore (when they see you both walking, they immediately turn the other way like they haven’t seen you at all), and even when your time with the other brothers is limited to the point where you see him and only him, but he truly does love you

Lucifer loves you. He let his walls down and even swallowed his pride when he admitted this to you, and he doesn’t want to regret it. Which is why he had to be the dominant force in this relationship. He wasn’t going to lose you again, he refused to. No one was going to take you away from him, lest they incur the wrath of the firstborn

Mammon

This demon was already clingy, so just amp it up to an 1000

Mammon already gets picked on by demons, witches, and even his own family. So when you started to defend and comfort him, he was smitten. You, a mere human, making the Great Mammon feel butterflies in his stomach? Had you told Mammon this 100s of years ago that he would fall in love with a human, he would have laughed in your face and blew you off. But here he was, head over heels in love with you

He was already following you, since he was deemed your protector, and he took that title very seriously.

“Oi MC, stay close with me, that creep’s walking too close.” “Human, ‘ya need to let me walk with you every class, what if some no-good demon’s plannin’ something and I’m not there?!” “MC, stay away from that scumbag, I don’t like him being near you...”

Your safety wasn’t a game, it wasn’t a risk he would be taking like he’s playing a game of poker. No. He loves you, and he hasn’t felt this kind of warmth since his days in the Celestial Realm. If it means that he would never leave your side (and trust me, he’s not complaining), then he was happy about it. Ecstatic even. You were a pure soul and you made him smile everyday, he wasn’t willing to lose you by a longshot

He escalated from being a puppy to a growling rabid demon, baring his fangs at anyone he deemed a threat (which was starting to be an alarming rate of people, even people that you both personally knew). Mammon would always have some sort of grip on you, ready to pull you away under the guise that he was defending you. It got to a point where it just seemed like he was always on edge, just picking fights for no reason, and it got to the point where you confronted him about it. These people were your friends! They weren’t random demons trying to eat you alive, they weren’t trying to torture you for entertainment, and you are your own person! You’re not just some possession, and you’re not a child! You can take care of yourself-

He didn’t like that at all

You didn’t understand it, you’re a weakling compared to everyone here, and you wouldn’t make it by yourself (was Belphie not enough proof of that statement?!). You needed Mammon, and he was going to be there protecting you, whether you wanted it or not. He failed once, and got a second chance, and he wasn’t going to waste it. And if you didn’t want his protection, that’s okay. You’ll grow to live and love him soon enough

Many people forget that while Mammon does act childish and does rather stupid things at times, he is the second born. The second most powerful brother right after Lucifer himself. He won’t (or at least tries not to) do these acts in front of you, no. He knows how vulnerable you can be, you’re not used to seeing vicious acts like these in front of you, but he is. Your classmate that wanted to do a study date for a big test? He’s trying to curse you so he can hurt you Canceled last minute and unenrolled from the class next day. Beel’s teammate that asked you for your number? He obviously wants to get some inside info to harm you Bones broken beyond repair to the point where he couldn’t play Fangol anymore and left in despair (you were only trying to plan a surprise for Beel since he’s been working so hard). The demon that accidentally bumped into you on the street? He tried to attack you and Mammon stepped in before it got worse You personally saw what he was capable of before you begged him to stop.

All in all, he’s the Avatar of Greed, it’s in his nature to be selfish. Before, he hated himself for how low his sin would make him feel, but damn did it feel good to indulge in it with it came to you

Leviathan

Out of all the bros to go yandere, he would be one of the worst to encounter. Good luck MC, cause you’re gonna need it dealing with his yandere side

Being that his sin is jealousy, it’s just a disaster waiting to happen. Why were you ALWAYS talking to his brothers and not him?! It’s not fair, it’s not fair!-

On top of that, he can be very manipulative, and he knows it. Whenever he talks down on himself, saying that he can understand why you would want to talk to other people instead of him. After all, he’s just a icky otaku who’s a worthless excuse for the third strongest brother-

Whenever he has this spouts, he knows that you’ll drop everything and come reassure him. You can always reschedule, he needs you now

With Levi, he knows what he’s doing is wrong, but he can’t help it, and he doesn’t care to. It took him so long to find real affection, and even then he still had his suspicions. You don’t really care for him if you keep trying to leave him, you don’t! Clearly, your love was just an act. If you really did love him, then wouldn’t you spend all of your time with him and no one else?

He knew that you couldn’t physically be with him forever, you weren’t immortal after all. But that didn’t mean that you couldn’t spend your remaining time with him. You could switch to online classes like him, constant anime and TSL marathons, and you could even watch him stream live! That sounded like heaven (ironically) to him and it would make him beyond happy, so why aren’t you agreeing with him? You would do this if Mammon asked or even if your hex classmate begged you too, so why not do it for him?? Was he not enough for you?! He knew that someone would try to steal you, and there will be hell to pay

Another thing, Levi was smart. Granted, not as book smart as Satan, but he was smart and sly. Always being stuck in his room, it gave him the chance to be stealthy since no one ever expects him to leave (unless it was for a rare appearance at RAD for student council meetings or something he was actually excited for and wouldn’t shut up about it). This gives him time for what needs to be done: collecting some “personal souvenirs” for himself and getting rid of some scum

Levi is like Mammon, many people forget that not only is he the third strongest, but he is the Grand Admiral of Hell’s Navy. They just don’t see him in this position of power because of his image as the shut-in otaku who fanboys over Ruri-Chan. But when he breaks out of that mentality, people should worry...

He doesn’t like to be super messy, his route is silent but quick. Doesn’t mean that it would be painless though, just quick and without much of a mess. Being an reptile/aquatic demon does have its perks, especially when it comes to using his venom

Levi, while he struggles with openly expressing his feelings, won’t have that much of an issue showing you how he feels. He may not be able to say it with words confidently, but he can definitely show you how he truly feels by never letting you go

Satan

Another one to where if he went yandere, he would be the worst to deal with

Satan, while he had a better handle on his emotions, still struggled from time to time. He is the Avatar of Wrath, and yes, you all didn’t feel like you had to walk on eggshells when conversing with him, it didn’t mean that you could just say or do anything

He still reacted in his angry ways, but it wasn’t nearly as ruthless as how it was before. For example, if you spilled something on him by accident, he’ll be just a little irritated, but after looking at your guilty expression, it would slowly drift away. He knows that you aren’t idiotic like some of his brothers , and it was you, he couldn’t stay mad at you no matter how much he tried. It would eat at him, anger turning into sadness, then clarity and understanding. And you were to thank for that

After the whole body swap fiasco, he gotten better with understanding emotions other than the usual fury that flowed through his body. And the ones that you would make him feel got him addicted, to say the least

Like Levi, he starts to understand that what he is doing can’t be right, but he doesn’t understand why. Satan, one of (if not) the smartest of the brothers, could not figure out what you were making him feel, until it finally hit him when you said the three words he desperately didn’t know that he needed to hear:

“Thank you so much, Satan! Seriously, I love you.”

This feeling became much clearer now. This...was how true love felt? Like the ones that he read so much about? This was like a dream come true then. He, a demon that born from literal wrath, was receiving genuine love. Someone loved him, and he refused to let that go.

He would occupy your time and space more, always offering to help you study for some tests or completing assignments, and even inviting you to come read with him. This was fine, it wasn’t an issue.

What was the issue was how territorial he was getting of you. Whenever someone else wanted to hang out or just be in your presence, Satan would lose his cool. It would start out slowly building with him making snarky comments out loud, saying that they were boring you and wasting your time when you could be with him. Then it would lead to him lingering around, sticking close to your side by either grasping your hand or, if he was feeling extra possessive, an arm wrapped tightly around your waist with him giving a threatening look at the offender. If none of these things were working however (Diavolo forbid if the person was ignoring him or even acting smug), he was ready to explode.

He didn’t want to scare you anymore than he already had. Satan knew that in the past that he used his reputation as the Avatar of Wrath to strike fear into people, including you when you first arrived here. But he was a new demon! He couldn’t make his anger or wrath go away, but he could control it and find new ways to release it instead of the usual rampages. And he wanted to prove to you that he wasn’t just the rage-filled demon, but a man that was more than capable of loving you

But he couldn’t, he wouldn’t, let this person get off scot-free. You noticed how tense he was getting, and before you could even blink he already had them dangling by their neck. You could make out some of the things he was saying, “How dare you think you can take MC away from me?! I won’t hesitate to end your pathetic existence if you so much as glance at them-”. He could feel you tugging at him, pleading at him to please calm down and that you could both just leave-

Well, why didn’t you say so earlier MC? All of this could have been avoided if you were just with him this entire time instead of this filth. As long as you kept giving him this euphoric feeling and have him feeling like he’s on Cloud 9, then everything will be fine. A non-rampaging Satan is a happy Satan, and a happy Satan is good for you and everyone around. Just stay in his presence, just give him love, and everything will be peaceful.

Satan is not a merciful demon, and when he acts on his wrath it gets very gruesome. If you want people to keep their body parts attached and not scattered across the Devildom (and not find their bloody heart at your door since they wanted you to have it so much), then don’t stray away from him. When Satan is with you, he feels content with everything, and he doesn’t want that to change. He wants you to be happy with him like he is with you, and he won’t let anyone get in the way of that

You were the beauty to his beast, and he was going to get his happy ever after, even if he had to tear through and rip apart every single person in the way, one by one

Asmodeus

Getting the Avatar of Lust to fall in love with you is a feat that was rarely (if not ever) obtained. It was both a blessing and a curse

A blessing to where you got the treasured fifth born to show you just how much he appreciates you for you, and only wanted your eyes set on him. A curse to where he only wanted your attention, and was furious if your eyes wandered off him for a millisecond.

You knew how Asmo was, he lived for the attention, the spotlight on him and only him, with people announcing their undying love and affection just for him. But there was a glaring problem with this

Asmo wanted you announcing your undying love and affection just for him. He loved his fans, but he didn’t love them like he loved you, and that was a problem for him. You made him fall in love with you, so it’s only fair that you deal with it, right? It’s only fair to love him as much as he did you right? Really, you were the one that was suppose to be madly in love with him, not the other way around

It doesn’t matter what you answered, loving him was the only choice that you had. Your head should be filled with thoughts of Asmo, your attention only set on him, your pretty lips only speaking praises and “I love you” just for him, you should dedicated to Asmo and only Asmo

What did you do to make him fall so hard for you? He’s no stranger to having flings and the feeling of love in general. In the past, he’s convinced himself that he was in love with certain people, but it would never last, the “love” that he felt fleeting. So for you to make him feel this emotion, to feel this true love for so long and it not leave him yet frightened him so much. He wanted you to need him, to feel like he’s your very reason to breath, to live.

And he hated it when other people took your attention away

Asmo definitely wasn’t the one to be messy (he still has to look his best and some pieces of trash was not about to change that), so he lets his charm do the job, literally. Who could deny his request when he tells them that they should just leave MC alone forever, and that maybe they should go pay Cerberus a visit if they’re so desperate for some attention.

All in all, Asmo is borderline delusional that loving him is by giving him your attention, always and forever. He loves you, and the bare minimum that you’ve been giving him (in his eyes) isn’t enough anymore. He deserves your love and affection at all times, even if it means that he would be the only person in your life, then that was even better. Your love was only fitted for perfection, and he was perfection, no one else

Beelzebub

Okay, so Beel is already the nicest brother out of the bunch, so I think he would be the least concerning yandere to worry about

He’s already soft when it comes to you and his family, and he’s protective of you

He’s very, very protective of you

Beel, although he’s among the youngest, is one of the strongest physically. He’s muscular and the tallest out of the family. He doesn’t even need to open his mouth to threaten anyone, he can just stand there and stare menacingly in the background, and whoever was there would run for the hills

He’s always around you, which isn’t a bad thing. All he does is eat (which he offered to share and even feed to you), make small talk, and walk with you to wherever you needed to go. Besides, to you Beel is a big cuddly teddy bear (just with really sharp teeth). He wouldn’t hurt anyone without reason. As long as no one was trying to take you away or hurt you, then everything was fine.

He is willing to share you, but only with Belphie. He’s used to sharing with his twin, and he loved the both of you too much to be completely selfish with you. Plus, he knew that Belphie loved you too. This was the perfect reality for him: having you, his twin, and food. It makes him and Belphie happy, and they’ll make you happy along with keeping you safe

Now, if someone did have the courage to try anything with you, Beel would have no problems eliminating the issue. He’s a nice guy, but he won’t tolerate anything if it deals with his family. He’ll be conscious enough to where he won’t handle it in front of you, if anything he won’t even leave a trace. He’s the Avatar of Gluttony after all, he always has an appetite.

Beel is a very understanding, but also very wary, guy. After the Fall and losing his baby sister Lilith and having Belphie taken too, he’s terrified that something can and is bound to happen to you again. He will be ready this time, he won’t take anything else as an answer. You’ll still have your freedom, and you can still hang around some of your friends (at least for now), but just know that Beel will always be around. He’ll be like your second shadow, and always on the go. He loves you, and he refuses to lose anyone else that he loves.

Belphegor

This man was already yandere, let’s be real

After the whole situation happened and he was given a second chance to build a real relationship with you, he wasn’t going to screw it up. Believe it or not, despite his laziness, he was going to try his hardest to create a genuine bond with you. Actions speak louder than words after all, and he wanted to show you how much he’s changed. He was indebted to you, you gave him the chance to be with Beel again, and to get out of that cursed attic (even though he did kill you afterwards and was playing you like a fool)

Very possessive and very selfish. If he had to share, it would only be with his twin obviously. No one else was going to have you, and he would make sure that was a fact. After all, all he needed was you and Beel, no one else

Also like Levi, very manipulative. He doesn’t want to be that way, but if it keeps you by his side and no one else’s then oh well, he’ll get over it. If it has to be done, it has to be done

You don’t need to go to that party with Asmo, it’s time for your nightly cuddle sessions. Don’t go with that idiot Mammon, he wants his cuddles now. Why are you going with Diavolo and Lucifer? Are you forgetting what they did to him, what his dear older brother did to him to save face? See what you did, you made him sad, maybe if you take a nap with him and forget about everyone else he’ll start to feel a little bit better...

He’s lazy, but don’t take his laziness for weakness. If someone is really starting to become a bother, he’ll happily eradicate the threat. He’ll leave the body behind too, he wouldn’t feel like cleaning up. Plus, he would be proud of his work. Many people think that just because his sin is Sloth is that he’s a puny demon, but they also forget that he’s one of the most powerful demons to even grace Hell. And like Satan, he’s not very merciful. He won’t be as savage and bloodthirsty like him, but he’ll make sure that the problem goes in an agonizing way.

MC, just know that Belphie loves you for you, and not because of the Lilith revelation. His words may not come across like he does, but what he doesn’t say with his words, he makes up for in action. I mean, you don’t have to worry about other demons being a pain because he’ll make sure that they’ll go away, and plus you can just stay in their room! Studies show that sleeping next to someone you love is super healthy and helps you sleep better in general, and who else is better for the job than him?

He’s going to prove to you that he really loves you, he’s not going to make any more mistakes, and he’s not going to have any more regrets when it comes to you, he’s going to make sure of that. No one is going to get in the way of the ideal dream: just you, him, and Beel. Not random demons, not the other exchange students, not even Diavolo. No one was getting in the way, no one.
