Yuuki Larka was tired of his boring life when he suddenly fell into a strange world called “Mato”, where dangerous monsters (Shuuki) were roaming everywhere. In this world, only girls have superpowers because they eat a strange fruit called “Peach”. When Yuuki was in the grip of death, Captain Kyouka of the “Demon Defense Force” saved him.
Kyouka has a strange power called “Slave” – she can make anyone her slave and use their power. Initially, she tried it on monsters, who turned out to be pretty useless, but when she used this power on Yuuki, Larka became a truly dangerous beast. Now Kyouka thought that this was the man who would take her to the top, so she asked Yuuki to join the force… but in a strange “special” position.
