Synopsis
Godou Kusanagi, a seemingly ordinary high school student, gets caught up in extraordinary events during a trip to Italy. He inadvertently becomes a "Campione," a God Slayer, after defeating a Heretic God in battle.
This new role forces him to confront other powerful and rebellious deities who threaten humanity. He must use his newfound powers to defend the world from these divine threats.
Along the way, Godou attracts the attention of both helpful and dangerous figures, especially powerful women who pledge their allegiance and support, leading to complicated relationships as he navigates his duties as a Campione. His life is forever changed, becoming a series of epic battles against gods to protect humanity from divine chaos.
