A dark revenge isekai where the weakest becomes the most terrifying.

Mimori Touka was never anyone special. In school, he was just a background character, easily overlooked. But when he and his classmates are summoned to a fantasy world, it feels like his chance to finally shine. Unfortunately, the gods have other plans—his abilities are so worthless that he's immediately cast into a deadly dungeon, left to die.

But power isn’t always what it seems. As Mimori begins testing his so-called useless skills, he discovers an abnormal power hidden beneath the surface—one strong enough to annihilate anyone in his way. Now, armed with the strength no one saw coming, he’s climbing out of the abyss, ready to take bloody revenge on those who betrayed him.

A brutal and action-packed fantasy, Failure Frame is a must-read for fans of underdog stories, overpowered protagonists, and revenge-driven narratives. Don’t miss the original light novels, the manga adaptation, and the upcoming anime!
