, 獅子神 皓

Hiro shishigami is the main antagonist of inuyashiki and a high school student who lives with his mother. he is currently on the run after being identified as the most dangerous serial killer alive, having been infused with alien cyborg technology that allows him to feel emotions through committing murder. initially, he caused traffic accidents and disruptions before moving on to commit serial murder, often targeting random families. his powers include flight, advanced combat abilities, advanced healing, seamless communication with electronic devices, and the ability to integrate technology into his body like ichirou inuyashiki. however, unlike inuyashiki, shishigami uses his powers for criminal purposes, such as murder and theft. it is unclear what may have led to his predisposition towards violence, but it could be due to bullying or living in less-than ideal conditions with only his mother.
