While heading to a nearby shop in the bustling city, Kazuya Shiina attempts to protect two little girls from an armed attacker, but he is stabbed and killed instantly. His heroic act grants him a rebirth in a different realm, retaining all his memories as Cain von Silford, the margrave"s third son.
At five years old, a church baptism opens a meeting with the seven deities ruling the cosmos. The gods inform him of his rebirth and bestow upon Cain their individual divine shields, granting him cheat‑level powers in swordplay, sorcery, and numerous other fields of combat and arcane arts.
Armed with these gifts, Cain embarks on a life he considers a dream realized. Yet it quickly becomes apparent that the deities intend more than merely granting him chaotic, all‑encompassing strength; they have a grander design that will test his resolve and shape the destiny of worlds.
