Yuuki Wakura wanders through a gate to an alternate dimension. He meets the Demon Defense Force including Chief Kyouka Uzen, who will reward him for his servitude.

Yuuki is recruited to work as a caretaker at the 7th Squadron’s dorm in Mato. Shushu catches him unaware and turns him into her boy toy. Suddenly, a giant Shuuki attacks!

With dozens of Shuuki detected, and a score to settle, Yuuki and the Demon Defense Force Squadron take an interdimensional trip!

Tenka wants Yuuki as her new pet, but Kyouka declines her request. Nei explains her clairvoyant powers, the “promise.”

Yuuki learns a less than peachy truth. Later, he receives a finger licking good reward.

With Yuuki tied up and unable to fight, it’s up to the girls to harness the power of the peaches in a non-stop battle. Suddenly, those who control the demons appear...

Yuuki finds a new reason to fight: to return Aoba to her original human form.
