Kaguya Kozuki

"Peace? so-called "peace" is a joke! That ideology is not the right solution to solve caused by . To think that you were  all this time, only that you can't even remember who you are now. You took everything from me, all my accolades and reputation as a scientist. I destroyed every bit what's left in your world, piece-by-piece! And those people who exploited your Rider System,  for example. Gentoku was nothing more but a disposable pawn, that includes you . It was me who led Takumi into his downfall! And, as for  right now...she is now but a hollow shadow of her former self. It was me all along, Sento Kiryu... Or rather, Takumi Katsuragi. It's always been ME!!! The architect of all your misery!"

It is also revealed that she is the true leader of, and she is the true mastermind behind the events of both the story and the canon TV series from the sidelines.

Past
Before the events of the TV series canon and the story, Kaguya and Ryohei Kusanagi were once close friends to. She was once considered a rival towards Takumi, until his success and achievements as a scientist made her increasingly envious towards him, and her jealousy towards Katsuragi sent her off the deep end.

Kaguya used to be a scientist for  before she founded Elpis Corporation one year after the. Sometime after the Sky Wall Disaster, she was the first to discover the. She and Ryohei got married and had a daughter together. However, Kaguya would eventually experiment on her child with Nebula Gas, until she was caught in the act by Katsuragi. Their friendship was fractured as a result. Kusanagi and their daughter somehow disappeared from her with their whereabouts unknown.

Kaguya's discovery of Nebula Gas would be studied by her former friend, leading to the creation of, the , and the , ultimately leading to the events of the and the story.

Personality
Kaguya is a pacifistic individual who grew tired of the ongoing conflict for the control of, desiring to unify the warring countries once and for all by any means necessary. She is generally calm, compassionate, and a charismatic anti-war activist leader. Despite this, as said by, she is capable of making decisions that are morally questionable at best.

Before she founded Elpis Corporation, Kaguya was a talented scientist who is recognized by the world through her unrivaled knowledge. Everything changed when she finds a rival in, one of her childhood friends. As time passes by, Kaguya becomes increasingly jealous with Katsuragi's success and achievements as a researcher to the point her jealousy gradually evolves into insane hatred, which causes a problem to her relationships with Ryohei and Katsuragi himself, to the point she would constantly abuse her own daughter to vent her hatred against her sworn enemy and used Sayaka as a test subject for the  out of spite. She would even go far to make Sento suffer even more after finding out his past identity as Takumi by having tortured and raped in an act of revenge by proxy.

While keeping in the guise of a benevolent anti-war activist, Kaguya's true personality underneath is that of an abusive, apathetic, manipulative, perverse, spiteful and self-centered sociopath who cares for nothing but her own goals. Possessing a massive God complex, she enjoys absolute domination and control, lusting for the power of in order to reshape the world in her own image. She regards the box as a sacred treasure and she entitles herself as its chosen protector. Unlike, , and , who were both affected by the light of , Kaguya proves to be worst than the three since she is one of the few people not to be affected by the box's energy who is also trying to exploit it, the other being. Ironically, despite claiming herself as a pacifist, Kaguya deems peace as an alien concept in her point of view, and chooses to adapt a "destruction before creation" mindset as a solution to stop the war, believing that humanity is beyond redemption; she aspires to create a new world without conflicts, suffering, and most of all, without free will.

It should also be noted that unlike other villains in the story who still have some level of ethics and morality (i.e., Shingetsu, Ryohei Kusanagi,, and to some extent ), Kaguya's villainy is taken very seriously, she enjoys dominating those beneath her and barely shows any remorse for her actions. She has no qualms in resorting to torture and rape just for the sick pleasure of it. Kaguya is incapable of feeling any love, especially from her family, only seeing them as objects of gratification than an actual family.
