Based on the adult manga by Toruneko.
Arata Asaoka lives with his despicable, chauvinist father and older brother.
A house of three men.
Arata was an illegitimate child. Bearing only a tenuous blood relation to the man who bastarded him into the world, he was treated like a second-rate human. With nowhere else to go, Arata suffered the cruelty of his father and brother for years.
For years, he forced a smile and pretended happiness for the sake of strangers…
One day he met the girl who gave him hope. Her name was Koharu Hinomoto.
She was a ray of sunshine. Being with Koharu made Arata feel good, and he fell deep in love. He began to believe that his life could be better.
Arata decided he would move out and live with her.
Even without money, they could make it work. Anything was better than how he lived right now.
Arata knew in his heart that he could make a warm, loving family with Koharu.
If he could just move out… before his despicable family ruins everything.
Kou is a member of the public morals committee at Moriyaji Gakuen, along with his childhood friend Ai and kouhai Karen. One day while he was making the rounds after school, he was attacked by a weird being. He was frozen in fear and could not evade its attack, but he was saved by two girls, Konoka and Lizera. They were ‘daemon busters’ who fight against daemons borne from the lust and cravings of humans. They told him that he was a kyuumashi who could absorb the desires that create daemons, and they asked for his help since his special ability makes their battles much easier. When he uses his ability, it causes him to be able to see girls naked and also makes them horny. If the daemons aren’t defeated, then their lust will cause the whole school to become an orgy. As part of the public morals committee, he can’t let that happen!
