Rin, a lackluster high school boy, is unexpectedly reincarnated into another world with 20 of his classmates following a fateful bus accident. A self-proclaimed god named Adora announces that “the person who becomes the most famous in this world gets to decide who dies.” As the gods’ ulterior motives gradually come to light and the heartbreaking reality is revealed, they find themselves caught in a struggle for redemption—banding together as allies and clashing as foes. What was meant to be their desperate fight over seven days (Earth time) in another world takes an unforeseen twist when Rin, the god declared capable of even greater feats than Himself, entrusts a profound sentiment to his childhood friend Hitomi.
