Synopsis

Based on the manga by Oku Hiroya.
 
Alienated from both his company and family, aging salaryman Inuyashiki Ichiro is approaching retirement with little hope left in his life. After being diagnosed with terminal cancer and given only a short time to live, Inuyashiki is consumed by despair, until a mysterious accident transforms his body into a mechanical weapon that gives him “superhero-like powers.”
High school student Shishigami Hiro also survives the same incident and gains abilities far beyond human limits. Unlike Inuyashiki, however, Shishigami chooses to use his overwhelming power to harm anyone who opposes him.
While Shishigami unleashes terror on innocent people, Inuyashiki fights to save the victims caught in his path. As two men gifted with unimaginable power clash over their opposing ideals, their destinies spiral toward an intense and inevitable confrontation.
