Backstabbed in a Backwater Dungeon: My Trusted Companions Tried to Kill Me, but Thanks to the Gift of an Unlimited Gacha I Got LVL 9999 Friends and Am Out for Revenge on My Former Party Members and the World

Human boy Light sets out to become an adventurer but is given the lowest rank. Some powerful and diverse adventurers invite him to join their party.

Three years later, Light has built a powerful nation in the depths of the Abyss. He receives a report from Mei that signals the start of his revenge.

Former Concord of the Tribes member Garou is likely to be the Wolfmen’s next chief. A human maid asks him to take her to where Light was last seen.

Hoping to gather intel on the other nations and raise his adventurer rank, Light sets out for the Dwarven city of Dagas alongside Gold and Nemumu.

After making quick work of the Quad-scythe Mantis, Light and his companions make camp with Elio's group. Meanwhile, Kyto and Yanaaq attack humans.

After Light and his friends are quickly promoted to D-rank, he hopes to make an even greater mark by taking on a quest to defeat an adventurer slayer.

As Gold and Nemumu battle Yanaaq's amalgamated creatures, Light resolves to drag Kyto and Yanaaq back to the Abyss to question them about the master.

The elf Sasha lives happily with her fiancé Mikhael, vice-commander of the White Knights. Meanwhile, Light and Ellie infiltrate the Elven Queendom.

Acting on information spread by Light, the White Knights set out to take the tower. Sasha, accompanying them as a guide, plots to kill Light.

The White Knights have been teleported to different floors of the tower. Mera and Iceheat face Nhia and Khia, while Suzu fights Sharphat.
