One day, he gets struck by a mysterious explosion in a park which leads to him acquiring a cyborg-like body and superhuman powers which he resolves to use in helping others and find the meaning of his existence. On the other hand, a young man named Shishigami Hiro (Murakami) was also affected by the explosion and decides to use his powers to kill mercilessly in a bid to bring about the extinction of human beings. As the paths of Inuyashiki and Shishigami cross, they are destined to fight each other as nobody but Inuyashiki can stop the latter.
The opening theme song of the anime will be "My Hero" which is sung by rock band MAN WITH A MISSION who is a big fan of the original manga.
