Failure Frame: I Became the Strongest and Annihilated Everything With Low-Level Spells

Touka Mimori is summoned with his classmates by the goddess Vicius to fight as a hero, but the ranking ceremony marks him as E class while others receive stronger titles. Vicius decides that a weak hero is useless and sends him to the Ruins of Disposal, a place meant to kill anything thrown inside. Most classmates accept the decision or stay silent, and Touka is left with only low level abnormal state skills such as poison, paralysis, and sleep. Inside the ruins, those rejected spells become deadly because they work on monsters that should have been far beyond him. Touka survives by staying calm, stacking effects, using corpses and terrain, and refusing to fight fairly when fair combat would mean death. By the time he escapes, the boy Vicius discarded has become someone who can kill stronger enemies before they understand the rules of the fight.

Touka hides his survival and begins moving under the name Lord of the Flies while aiming for revenge against Vicius. He rescues and allies with Seras Ashrain, a former knight hunted for political reasons, and later travels with Piggymaru, a slime that becomes useful through trust rather than rank. Their road leads through assassins, slave markets, monster lands, and people who have also been used by those in power. Touka keeps his methods cold because he knows mercy toward enemies can become a weapon against him, but he does not treat allies as disposable pieces. Meanwhile, his former classmates are split into hero groups under Vicius’s control, with some doubting her and others sinking into arrogance. Touka’s revenge grows from simple anger into a plan to expose the goddess, protect the few people he chooses, and turn the very skills called failures into the tool that will bring her down.
