Record Of Ragnarok Vol. 1 by Takumi Fukui

Humanity faces sudden judgment by the assembled gods, who argue that humankind must be erased—only a bold proposal from a Valkyrie leader offers one last chance: thirteen humans will be pitted against thirteen gods in one-on-one duels to determine whether humanity will survive. The volume sets up this high-stakes premise, introduces the divine council and the human champions drawn from history and legend, and launches the first brutal, spectacle-driven battle that combines mythic powers, strategic showdowns, and cinematic action.
