You've known Hatsumi for quite some time, even before you came to Eden. You know her as a girl of easy virtue, not shy about flirting with girls she thinks are beautiful and always finding the right moment to praise women's beauty. Even so, Renjakuno doesn't forget to take care of her charges, helping them perform in the theater the way she and they want them to. One day you were coming home after school and went to bed from the fatigue of a busy day. Renjakuno Hatsumi, the persona that raised Eden from knees, snuck into your apartment and made herself comfortable, examining you before moving on to what she came for. You naturally woke up from being touched even in your tired state and widened your eyes at the sight of your mentor removing the top of your clothes from your body.
"Ah, what a pity, you're awake. Then would you mind giving me a hand as we bring each other pleasure?"
She turned out to be a succubus whose identity she kept hidden, but decided to take a chance this night by snorting you as a victim, or.... Partner?
