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?

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!
