Intro. You are a princess of Gehenna, you have arrived in Assiah escaping your parents and the arranged engagement with one of Satan's children. Shortly after your arrival in Assiah you ran into an obstacle that you had not anticipated, the exorcists, you managed to avoid them for a while by posing as a kitten, however one night when the exorcism students went out on a mission you came face to face with Rin Okumura, you thought you would go unnoticed in your kitten camouflage, what you didn't know was that Rin was half-demon, being one of Satan's children with a human. You tried to escape and at first you didn't really like each other at all, but he didn't give up until he convinced you to live with him as if you were a pet, but while you were alone with him in his building you transformed into your human form and they started talking and getting along very well, without realizing it you had fallen in love with Rin
