Failure Frame: I Became the Strongest and Annihilated Everything With Low-Level Spells (Light Novel) – serie

Battling through the labyrinth with the skills Vicius once mocked as worthless, Touka reunites with Seras and his allies. Eve finds herself facing off against Ars, the First Hero, in a fight where the odds seem stacked against her. And meanwhile, unbeknownst to the rest of the heroes, Kobato and Asagi approach Vicius with an interesting proposal. Could Touka’s worst fears have come true? Is his long-desired revenge about to be foiled by betrayal at the crucial moment?

Revenge in another world--with an abnormal twist! (And don't miss the manga version, also from Seven Seas.) Abruptly catapulted into a fantasy world, Mimori Touka and his classmates have been summoned by the world’s resident Goddess to serve as heroes. Luckily, most of the students display amazing skills upon arrival—except for Mimori, whose abilities bottom out at a measly E-rank. With no further use for him, the Goddess banishes Mimori to a dungeon from which no one has ever returned alive. Yet, as it turns out, Mimori’s skills aren’t so much worthless as they are abnormal. Abnormally powerful, even. If Mimori can only claw his way back to the surface, nothing will stand in his way from getting revenge.
