Hiro Shishigami

Hiro Shishigami (獅子神 皓, Shishigami Hiro) is a high school student and a criminal. He is the antagonist.

Appearance
Hiro is a young man with short, navy hair and black-brown eyes. He has a particularly pretty face, to the point that he attracts a lot of attention from females around him. He is also shown to be at least of medium height, potentially tall.

Personality
Although he appears kind and polite, Hiro is a sociopath who uses his cybernetic power to murder people that annoy him, or slaughter families to make him feel alive. He believes that with his new power, he is now above everyone else, and no one on the planet can stop him. However, despite his homicidal desires, Hiro is not completely monstrous. He is shown saving and helping people at multiple points, both unprompted and also as guided by those he cares for. This suggests that Hiro has some humanity lingering in his system, as he is also shown to love his mother dearly and care for a close few around him, such as Ando or Shion Watanabe. Although Hiro's cybernetics might contribute his sociopathy, other factors such as living with his mother in a rundown apartment and his father having another family, the frustrations of high school life, and dealing with bullies might have also be responsible for becoming the person he is now.

Plot
Hiro was an average high school student who was unfortunate enough to be caught in the blast of a UFO explosion. The extraterrestrials, not intending to kill any intelligent life, decided to remake Hiro, replacing his organic body with a cybernetic one. This results in Hiro gaining extra ordinary powers. Ichiro Inuyashiki was caught in the UFO blast as well and his body was also remade with cybernetics.

With his new powers, Hiro feels like he's not human anymore. To feel alive and human once more, He goes into different cities and murders entire families. He started killing after witnessing, one day after coming from school, a man killing himself by jumping onto the train's station rails.undefined By seeing other people's life vanishing away, he feels alive.

Hiro's childhood friend, Naoyuki Ando, who is in his class is victim of bullying by other classmates and that causes him to skip on many classes. To help his friend get out of that situation, Hiro savagely kill the bullies while they're at school. Seeing his friend kill people scared Naoyuki and he decided to break his friendship with Hiro.
