It's not an easy life for an OYash. Yamato spent his days in boredom, until one day angels and demons appeared before him. Their long feud had grown tiresome, so the humans were chosen to be the third party in the peace negotiation. And Yamato, of course, the human representative. The contract is signed, the pretty angel Sara Mitra Ayrun is left by the angels, the sexy demon Firika Mia Satana by the demons. Strange, but quite pleasant, the hero thought. Soon Firika, in order to get the hero on her side, had sex with him. The angelic Sara, who flew in after him, was trapped and robbed of her virginity. Thereby Yamato involved the human world in a depraved confrontation between demons and angels! How will the fate of the hero surrounded by four beautiful girls turn out?
