After inadvertently managing to kill the god Verethragna, taking his divine powers in the process, the once-typical teen Godou's life changed forever. Now a "Campione", a god slayer, the boy constantly attracts both gods' and other Campiones' attentions alike, not to mention the affections of a powerful knight, Erica. Whether he's dodging Erica's advances, proving his strength to others or taking down gods who will wreak havoc on the planet, Godou's new life is anything but normal.
