Campione! follows Godou Kusanagi, an ordinary high school boy whose fate is forever altered when he accidentally slays the Persian god of victory, Verethragna. By killing a god, Godou becomes a Campione — a legendary god-slayer granted both a blessing and a curse.

As a Campione, Godou inherits the divine powers of Verethragna’s ten authorities, allowing him to take on multiple godly forms such as the Bull, Ram, White Stallion, Boar, The Wind, The Warrior, and more. With these overwhelming abilities comes a heavy responsibility: he must battle and defeat rogue gods that threaten the balance of the world.

Godou’s awakening as a god-slayer also draws the attention of powerful and beautiful women from secret magical and religious organizations. Among them is the sharp-tongued and cunning sword-mistress Erica Brandelli. While they claim to support him, their true intentions may go far beyond simple cooperation.

Blending mythology, intense action, and romantic comedy, Campione! delivers epic battles between gods and humans while following Godou’s struggle to survive as a Campione — all while navigating the chaos of having multiple strong-willed heroines vying for his heart.
