Backstabbed in a Backwater Dungeon: My Party Tried to Kill Me, But Thanks to an Infinite Gacha I Got LVL 9999 Friends and Am Out for Revenge

In Backstabbed in a Backwater Dungeon (2022–present, Seven Seas Entertainment), a betrayed adventurer survives his party's murder attempt and unlocks an infinite gacha system, summoning overpowered allies to fuel his quest for revenge. Illustrated by Takafumi Oomae, this ongoing series blends isekai-style fantasy with a gritty survival premise, as the hero builds a LVL 9999 army from the depths of a forgotten dungeon. Its 11-issue run so far has carved a niche for fans of dark, system-driven power fantasies.
