New revenge Anime Backstabbed in a Backwater Dungeon set for 2025

A gripping new anime series is set to make waves this Fall 2025. Backstabbed in a Backwater Dungeon, an adaptation of Shisui Meikyō’s best-selling light novel, promises an intense blend of fantasy, betrayal, and revenge. With its dark undertones and emotionally charged storyline, this upcoming anime is already generating buzz among fans of gritty underdog tales.
The story centers on Light, a low-level adventurer betrayed by his own party and left for dead in a dungeon. But instead of meeting his end, Light awakens a game-changing ability called Unlimited Gacha. This rare power allows him to summon powerful allies, legendary weapons, and epic resources at will—turning him from a castaway into a deadly force fueled by vengeance.
Among Light’s first allies is Mei, a mysterious and lethal maid whose loyalty becomes one of his greatest assets. With each new summon, Light builds a team not to save the world, but to hunt down those who betrayed him—and exact justice in the most unforgiving ways.
The anime adaptation of Backstabbed in a Backwater Dungeon is being produced by J.C.Staff, the renowned studio behind hits like Food Wars! and A Certain Magical Index.
Katsushi Sakurabi takes the director’s chair, while Hiroshi Ōnogi, a veteran of the anime industry, handles series composition. With this experienced team at the helm, fans are expecting a faithful and visually captivating adaptation.
The original manga, illustrated by Takafumi Ōmae, has already cultivated a solid fanbase and is officially licensed in English by Seven Seas Entertainment. With the anime now in production, the franchise is poised to expand its global reach.

What sets this series apart is its emotional core. Backstabbed in a Backwater Dungeon dives deep into themes of betrayal, trauma, and the personal cost of revenge. Light’s transformation from a betrayed adventurer to a strategic and fearsome summoner adds a layer of psychological intensity not often seen in dungeon-crawler anime.
Fans of titles like The Rising of the Shield Hero, Arifureta, and Re:Zero will find familiar elements—high-stakes survival, character-driven arcs, and an MC who refuses to be broken.

Backstabbed in a Backwater Dungeon is set to premiere in Fall 2025, and anticipation is already growing. More details, including the official voice cast, streaming platforms, and trailer, are expected to be revealed in the coming months.
