In this ongoing revenge fantasy from Kōdansha’s Magazine Pocket imprint, a betrayed adventurer, left for dead in a dungeon’s depths by his own party, awakens with the gift of “Infinite Gacha”—a power that summons allies of level 9999. Armed with this unstoppable new team, he turns his fury on his former comrades and the world that wronged him, delivering cathartic payback. Running since 2021 with 21 issues, the series is a brisk, crowd-pleasing entry in the “revenge and humiliation” genre, known for its over-the-top escalation.
