About Backstabbed in a Backwater Dungeon
Backstabbed in a Backwater Dungeon is based on the Japanese light novel series written by Shisui Meikyo and illustrated by tef. The story follows a man named Light who is betrayed by his trusted allies and left to die in an uncharted and perilous dungeon. Using a mysterious magical ability known as the “Unlimited Gacha,” Light begins to summon powerful allies and rises to become an unstoppable force bent on revenge.
The series has drawn attention for its unique blend of dark fantasy, isekai tropes, and revenge-driven narrative. The official English edition of the light novels is published by J-Novel Club, who provide the following description:
“When Light is kicked out of the Concord of the Tribes, his former comrades instantly turn on him. Light escapes this diabolical act of betrayal by the skin of his teeth—only to find himself in the deepest part of the Abyss, the most dangerous dungeon in the realm! To avoid being eaten by carnivorous monsters, he uses the Unlimited Gacha, his sole magical skill. Where it previously only produced junk items, this time Mei—a gorgeous Level 9999 fighter in a maid outfit—springs forth! Three years pass and Light has carved out his own kingdom in the dungeon, summoning a powerful group of allies. Now a formidable Level 9999 Overlord, Light sets out for the surface to seek vengeance on those who betrayed him.”
