Framed for a crime he didn't commit, Kiska is warped to the deepest level of the dungeon, a death sentence for a non-adventurer with no abilities. But just as he's preparing to die, a mysterious voice grants him the skill "Save & Reset," allowing him to rewind time. This blessing is only the beginning of a new hell, however. The true powerhouses of this dungeon are a pack of beautiful girls out to destroy him, and unless Kiska can use his infinite tries to charm them, he'll be stuck in the abyss forever.
