神々の間で『人間にチートを与えて異世界に送り込みショーとして楽しむ』という遊びが流行っていた。その一人として選ばれた神原カナタは神の不興を買い、最も危険な迷宮《地獄の穴》へ送り込まれてしまう。絶望的な状況下で不死者の少女・ルナエールと出会ったカナタは迷宮を抜け出すため、修行をお願いした……のだが、過保護で寂しがり屋の師匠による修行はなぜか中々終わらず!?
The play of “giving cheats to humans and sending them to another world to enjoy as a show” was popular among the gods. Kanata Kamihara, who was chosen as one of them, buys God’s disappointment and is sent to the most dangerous labyrinth, “Hell’s Hole”. Kanata, who met the immortal girl Lunaere in a desperate situation, asked for training to escape from the labyrinth … but for some reason the training by the overprotective and lonely master did not end !?
