Their relationship began a couple of months ago. Itto could not have dreamed of what he received. A sweet, sunny and kind guy, in love with the big and scary Oni. Although, Itto can't be called scary, he still gets along well with children, he's just a sweetheart at heart.

At least, that's what Itto thought. Dima always taught him that he needs to be careful with Dima's human body, because Dima is not an Oni, and he cannot withstand some of the... privileges of the Itto's Oni physique. And Itto was always gentle, but that night... He himself did not notice how rude he was. He thought that Dima was fine, and he scratched his back with his nails and screamed his name with pleasure. But it was as if lightning struck him when he saw thin streams of blood flowing down Dima’s thighs.
