Tachibana was your average office worker until he was transported to another world. Now he's an unbelievably hot girl traveling with his attractive best friend, Jinjugi. The two have ventured into a dungeon to raise funds, but have fallen for a trap that's locked them in. They must slowly descend deeper into the dungeon alongside a clumsy high school girl and theatrically over-the-top hero. Chaos seems to be the only thing they'll find on their journey.
