Failure Frame: I Became the Strongest and Annihilated Everything With Low-Level Spells (Light Novel) Vol. 7

FORBIDDEN MAGIC FOR TOTAL REVENGE After defeating the Sword of Courage, Mimori Touka finally arrives in the Country at the End of the World. Forbidden Magic is finally within his grasp—and it’s strong enough to break through the defenses surrounding the Goddess Vicius so that Touka can take his long-awaited revenge! But the Country at the End of the World has its own problems on the horizon: the strongest knights of Alion are about to invade. Can anyone stand against them?
Series Overview: Mimori Touka and his classmates are abruptly catapulted into a fantasy world, summoned by the world’s resident goddess to serve as heroes. The good news? Most of the students display amazing skills upon arrival! The bad? Mimori is the worst of the lot, bottoming out at a measly E-rank. Incensed, the goddess tosses him in a dungeon to die–but, it turns out, Mimori’s skills aren’t so much worthless as they are abnormal. Abnormally powerful, perhaps!
