Aiko Mimura is a reborn individual carrying memories of a past life. She rises to become a military leader who unites the world under her command and abolishes all organized religion. Haunted by unresolved anguish, she manipulates time to alter historical events and confront threats to humanity’s future. Her journey begins in a repressive Catholic school where she ignites a revolt against a corrupt hierarchy, freeing herself and fellow victims from exploitation. Later, she commands a global coalition, rejecting rigid dogma forged through betrayal. Her form mirrors humanity, with brown hair, grey or green eyes, and a teenage presentation, though latent otherworldly traits linger beneath the surface. Her drive merges existential fury with methodical ambition to annihilate structures of control, whether divine or mortal.
