Nataru Shinmyou, forged as a flawed Ixuran supersoldier designed to bend reality, was stolen in infancy by the East Alta terrorist faction. Deemed a failed experiment, he narrowly escaped execution through the intervention of Dusk, a rogue member who raised him on Alta. There, he endured persecution for his mixed heritage while forging a protective bond with Birdy Cephon Altera, whose defiance against his tormentors kindled his devotion and unspoken love. The collapse of Alta’s central tower forced him into exile on Earth, where he cloaked his past under a human identity, working as a gentle nurse and therapist. His quiet life in a Tokyo hospital drew solace from Shoko Kagami, an orphaned girl, until the Ryunka bioweapon obliterated the city, claiming her brother Yuuichi and thousands more.

Grief mutated into vengeance. Nataru descended into calculated brutality, hunting Ryunka’s architects with torturous precision, convinced their suffering should mirror their victims’. His reality-distorting powers—teleportation, spatial rending—hollowed his body, leaching vitality through hemorrhagic fits and chronic pain, numbed only by escalating drug use. Though he maintained a compassionate exterior, self-hatred festered beneath, amplified by Dusk’s conflicted loyalty to his violent path and rivalry with Valic, Dusk’s biological son, who envied Nataru’s place in their fractured family.

Reuniting with Birdy briefly rekindled hope, but their ideals collided: her faith in order clashing with his nihilistic wrath. Their final battle amid Tokyo’s ruins culminated in Nataru embracing his mortality, acknowledging his spiral into destruction while confessing enduring love. His death left fractured bonds and scarred survivors, a testament to vengeance’s corrosive toll and the ghosts of choices etched into memory.
