Roxas & Naminé are Twins

While Naminé considers herself a Mutant Nobody of Kairi, it is CANONICAL that it was Sora doing THIS

"created" Roxas and Naminé.

Excluding the presence of Donald & Goofy, there are THIRTEEN HEARTS involved in this scene:

all seven hosts of the Primordial X-blade's Light, six within the Keyblade of Heart that Sora uses to "unlock" himself;

the Darkened Hearts within Said Keyblade's creator: Riku, as possessed by Terra (as possessed by Xehanort);

the Morally Dubious heart of Eraqus, hidden within Terra so as to settle its Decades Long Marriage Dispute with Xehanort;

the Hearts within Sora's: his own; Kairi's, the final host of the First X-blade's Light; & Ventus, recovering survivor from Xehanort's LAST attempt at forging a x-blade.

With so many Hearts involved in their creation, all of them Powerful in Light &/or Darkness, it is little wonder that the Twin Nobodies Roxas and Naminé are such Magical Powerhouses.

Roxas being able to Dual Wield Keyblades, regardless of how un/entangled he may be with the Hearts of Sora&Ventus or Xion at any given time, seemed to have a simple explanation: Roxas has 1 Keyblade for each Heart he "had", 1 from Sora & 1 from Ventus).

Except... Roxas had a Heart of his own the whole time.

"Roxas only has two hands" is a Valid Point, as is "the 2 Hearts were those of Ventus and Roxas, Sora's Heart was with his Heartless": neither point addresses Roxas retaining his ability to dual-wield keyblades in KH3.

It's Plausible that Roxas is currently capable of dual-wielding keyblades due to his Replica body hosting both the Roxas Heart yeeted from Sora AND at least 1 Data Roxas, as sourced from Data Twilight Town &/or The Garden Of Assemblage (the Secret Boss Room in KH2 which hosts Data copies of the Organization XIII members players defeat).

It seems more likely, however, that these Hearts would "merge" into 1 Roxas: the Hearts (& memories) developed by other Organization XIII members (excluding Xion & Xemnas) seem to have merged or otherwise integrated with those of their Others upon "recompletion".

The Heart (& memories) of Saïx & Axel were inherited by the "recompleted" Isa & Lea.

This seamless integration was likely due to there being no conflicting memories between their time as Nobodies and as [Recompleted Persons], all "parts" having accepted each other as being "one soul".

...something that would ALSO be true for the Roxas within Sora's Heart and any Data Copies of him added to their new Replica body.

So, unless we see Axel Dual-Wielding Keyblades in a future game, the "simple" explanations for why Roxas has that ability are most likely related to the context of his & Naminé's creation, born of sacrifice and all of the [Primordial X-Blade's Light] and [Whatever The Heck Riku Is].

The only other characters seen dual-wielding keyblades are Xion (who was siphoning memories & power from Sora, Riku Replica, & Roxas), Sora (with his Heart Hotel)... and Riku.

Riku, who casually forges new, unique keyblades at will. Riku, whose 1 Heart forged the currently & simultaneously-wielded keyblades of Sora (Kingdom Key), Kairi (Destiny's Embrace) &, potentially, King Mickey (Kingdom Key-D). Riku, whose reaction to his own (also distinct & simultaneously existent) keyblade breaking was "guess I'll summon a new one now" and then DOES THAT, when AQUA needed the miraculous connections she had with 3 other people (all of them in varying states of not-alive) to summon the keyblade BEQUEATHED to her (Master's Defender, the keyblade wielded in-life by Eraqus, and a keyblade inherited by pupils from Masters in a tradition begun by Ephemer after HIS receiving the keyblade from Brain).

Riku, who was used to forge the very Keyblade of Heart that created Roxas & Naminé im the first place!

(Riku is NOT NORMAL, okay? and this was true WELL before he casually became Sora's Dream Eater AND JUST AS CASUALLY CHANGED BACK: for humans, the transformation to "spirit" tends to be FINAL and ONE-WAY)

Other Assorted Oddities:

Sora gained a new body independently from Roxas (or Naminé, in KH1.

Ventus, the "third" Heart credited with the creation of Roxas, had his body VERY safely secured in Castle Oblivion by Aqua and seems utterly unaffected by either Nobody's creation & all subsequent shenanigans.

Kairi had been functioning as her own Nobody for almost the entirery of KH1: this again underscores how ??? Naminé's existence is.

with the exceptions of Goofy and Beast, ALL the characters at Hollow Bastion when Sora "unlocked" himself were probably capable of making Sora a "new" body (together if not individually, in the cases of the Disney Princesses & Kairi). it would have been somewhat out of character for Maleficent or Xehanort's Heartless but Riku is VERY WEIRD and he had some influence with both of them at that time: Riku may have summoned up a new body for Sora in the same way he summons new heart swords. It does, however, seem most likely that Sora's Magical Recompletion was a Joint Effort from the Princesses of Heart (as channeled by Kairi).

Kairi, as a Princess of Heart/Vessel of Light, cannot form a Heartless nor a Nobody: this is something brought up by multiple differently well-informed sources of worldbuilding lore. Naminé CANNOT be Kairi's Nobody: her being a Twin Nobody of Sora, alongside Roxas, makes much more sense even without the Additional Factors of Princess Hearts and Riku's role in turning Said Hearts into a Magic Key Sword that Sora stabbed himself with.

Vanitas???

i am belatedly realising that from a Certain (Very Crack) POV, the way i've described Roxas and Namimé's "birth" kind of mkes them fit the Criterium for being that "Child of Destiny" thing. since 2 of their "parents" (Riku & thus, through Gay Love, Sora) ARE said Child of Destiny. Naminé & Roxas as "Grandchildren of Destiny?"

Naminé's powers over Memory seem more in line with the (implied) capabilities of the Princesses of Heart working collectively than any of them individually: this may be a Plot Point, when the New Seven Lights are assembled, or have already played off in that First, "Doomed" Timeline of KH3's Keyblade War (thus Naminé's presence in the Final World & the weird "death" Kairi had in Timeline 2).

All of the above (crack included) are Additional Complications to the assumption that "Roxas is Sora's Nobody and Naminé is Kairi's".

While all four characters in that equation "agree" with this assumption does mean that it is "true": it does not at all, however, seem to be entire "Truth". ,

"So, how was it?" Riku swore his heart skipped a beat. Was it because Oscar asked about his date or the fact he was standing this close to him? They always bro hugged each other, it was just a surprise that he did it from behind. "She's really nice," Riku said, "But umm, I dunno is it too early to tell?" he was about to tell him how he knew her when Oscar replied, "You just have to let time pass and see what happens!"

if kh4 wants to be good it’s gotta have like sora excitedly telling strelitzia all about his best friends and how great they are but then it cuts to them acting insane

like ‘my buddy riku is really cool and heroic!’ he’s always got a clear rational head’ ((cuts to riku flipping over cars and/or threatening ppl in quadratum screaming ‘WHERE IS SORA’))

‘oh oh oh and kairi is so kind and brave… her pure and strong heart never falters!’ ((cuts to kairi having a full-on mental breakdown blubbering and sobbing in aqua’s arms))

i had a dream where something was off with riku’s shadow…

riku kingdomhearts is gay: a gifset

bonus data-riku:

and one based on some post i cant find now with the line ‘is he... you know [puts hand on hip]’

Kingdom Hearts Re:coded - Finish Commands - Spinner Ray

Remember how ReCoded just casually drops the fact that this is a “true memory” from the heart of Destiny Islands even though we literally see Riku get swallowed up by darkness in KH1, we watch it happen with Sora before the islands get totally wrecked like this, so how could Riku also leave through this portal afterwards

Thinking about the parallels between Riku losing himself to darkness because he (believed) his life-long friendship had been broken and replaced and Terra losing himself to darkness because he wanted to protect his friends/friendship more than anything else

you know what was cruel and unusual of the i7 writers to do? to have Yamato, who hated his dad, try reconciling with him for the sake of others and getting back love and support while Sogo, who still loves his family in his own way, tries to reconcile with his dad for the sake of others only to almost have his career ruined and his close friend and partner nearly jailed for a crime neither of them committed

Everyone’s all “OO MARVEL WORLD” this and “STAR WARS WORLD??” That but you know what we should REALLY think about for KH4? Muppets

The thing about utsukushii kare, yes I'm saying this after everyone that has to see it has seen it is that you got to get on tumblr and read some high level analyses and meta in order to realise the underappreciated misjudged worth of it. A trope is a commonly used theme, only when it's fledged out to the maximum to the point where it becomes unrecognisable from the tropey shit you see is when it becomes real. I've seen time and time again people failing to see the qualities of UK mistaking it for the usual romanticization of toxic dynamics u see in just about any mainstream well loved media. I know that's what i subconsciously did when the first season came out and settled for fmvs and paid no further attention. Mainstream rendition of popular tropes have seasoned us for casual viewing. especially deeper more convoluted stuff like the psychology behind characters like hira/kiyoi. there's a difference between normalizing toxic dynamics and portraying the working of it. One straight out romanticizes toxicity and gets us to think it's okay 'as long as they love each other' while the other addresses it's problems one by one and carefully breaks it down. It explores the taboo nature of certain dynamics and the fine line between purposeful manipulation/imbalance and circumstantial misfortune. For ex. lack of proper communication may be a character's problem without being their fault. Because i totally lack the articulacy or knowledge to pick it apart word by word I'm just going to say Sometimes that's just how their brain works. After years of neglect and struggle, that's how people end up sometimes. This by no means exempts them from blame for the harm/hurt they unwittingly cause. But we need to take time and patience to understand why. Why? Because these people are trying. They're yet to realise a lot of things still and despite being together for what years?? still dysfunctional but they've been giving their best. They'll grow. Together they'll heal and learn to be better for each other, for themselves. But we need to stick with them and be patient to witness that growth. I know I'm speaking this confidently about utsukare cause I've seen it's worth up close after i was impossibly drawn to it when the second season came out and from the posts i read of several smart eloquent observant perceptive attentive people. it has pretty much been very show stopping ground breaking phenomenal to me. I hope people that are yet to see it come to know of it too at some point. Or else you are terribly terribly missing out.

"no, our hands will never be clean but at least we can hold each other"

you need some adidas ambassadors? they're your perfect guys

Can you believe we got soriku parallels with all of these Disney couples?

was trying to see if i could outclass a triple-a unreal engine game in the whimsy department (i think i did.)
