Hikari (Kingdom Hearts: The Heart Sanctuary)

Summary
Hikari (Kingdom Hearts: The Heart Sanctuary) is a hypothetical what-if character  that takes place hundreds of millions of years after the events of Kingdom Hearts 3 & 4.. She is the Subconscious Creator/Mistress of the Heart Sanctuary, a special place in the now defined Kingdom Hearts Multiverse which is essentially the protector of the Strongest Heart in Existence .... Herself. Those who are worthy of even attempting to scale the Heart Sanctuary has specific qualifications. Once you do, you scale subfloors and floors too numerous to be counted by  any form of calculation, to reach the top and claim the Strongest Heart as your own. The entities in the tower are the strongest in existence, far surpassing the strength of the Strongest Keyblade Wielders and even Keyblade Masters

She is a main plot point of the "Hearts Sanctuary" series, being the one the Big Bad of the Arc was trying to find to essentially go back into the distant past and start over where Xehanort nearly suceeded at doing several times before : Forging Kingdom Hearts. And with her heart as a power amp, it would be completely easy accomplishing the task.

Appearance
Hikariis a 5"6 (about as tall as Kairi from KH3, as in this saga she was referred to as a "Legend" ) Caucasian female who wears a long turquoise  dress that seems to stop a bit into  her smooth, supple thighs.She wears some white sandals, which seem to be a very reminescent reference to Namine from the Rechain of Memories arc. She has mid-long blonde hair . She is usually seen drawing in her journal about the entities who just so happen to make it to her Castle, regardless of their sucess at reaching her or not.

Personality
She is seen as a very shy young woman. Appearing to be a social outcast, she is actually very awkward at speaking with others, responding with stuttering and finger twiddling. She isn't experienced whatsoever, and usually has her 'Constructs' do the conversation to avoid her getting anxious and not being able to talk at all.

Also has every ability in the history of Kingdom Hearts

Attack Potency: At the very least Multiverse Level+ (Created the Heart Sanctuary and the entirety of it's functions. To even remotely compare, the Kingdom Hearts Multiverse follows quantum branching but starts off with a endless infintie^'s of a number of timelines so great that even if Cantor's Antics started again, with the Bottom & Upper Antics with the same difference in distance to one another, with the bottom being the concept of Absolute Infinity, then it went up, and then the next thing became the lowest, and continued a inaccessible cardinal number of times, the top cardinal at the last time wouldn't even remotely be comparable to a fraction of the timelines. Then, each of the universes branches off to that many number of timeslines, and the branching continued after that. The X-Blade  in every set reality has to power to destroy the Multiverse and all possible diverging timelines to be by merely letting it exist, and there are as many within each timeline as there are maximum number of timelines within the Multiverse. Master Asmodeus, who was already superior to said number of X-Blades in every diverging timeline combined, absorbed said X-Blades and attempted to use them against the mere first sub-floor of the Heart Sanctuary to gain access to the Chosen One. He was defeated by a mere Regular Shadow heartless manifested in said reality, not even getting to the final boss of that floor. Each floor's Final Boss transcends the previous floor's Final Boss as it transcends a mere mortal. There are as many sub-floors as they are possible maximum number of timelines. The 1st Floor's Final Boss transcends the previous sub-floors' Final Bosses combined it as it transcends a mere mortal. There are as many floors as there are possible maximum timelines, leading up to the Golden Castle of Hearts, Which views the Heart Sanctuary as it views a mere mortal, and is powered up by the mere existence of the Choosen One's Heart, unamking and creating itself too many infinite^'s to count every planack length.)

Speed: Unknown. MFTL+ via Guardians + Constructs (They easily reacted to Master Asmodeus, who even as a little boy was stated to have surpassed Ventus at the peak of his speed & agility)

Weaknesses: Is a general softy and usually won't be going all out at the start of the fight.

Notable Attacks/Techniques: Her Guardians have every technique ever recorded in Kingdom Hearts, as the Guadians embody the very conceptualization of Keyblades & Hearts throughout the Multiverse.
