Hiro Shishigami

Once an ordinary high schooler, Hiro Shishigami's life was irrevocably altered when an alien encounter forcibly transformed him into a cybernetic weapon. Embracing random acts of killing as a means to feel truly alive, he embodies a chilling antisocial worldview that places no value on human life. Yet beneath this brutal exterior lies a startling contradiction — an intense, almost obsessive tenderness toward his mother and closest friend. Positioned as the ideological antithesis to protagonist Inuyashiki, Hiro represents a tragic villain perpetually torn between indiscriminate destruction and an unwavering desire to protect those he holds dear.
