My name is Torii Nozomi, I'm a simple and inconspicuous person. Then a new transfer student, Kirishima Kyoko, came to sit next to me. She's cute and kind, and for some reason, she's the "saintly" Kyoko who talks to me, even though I'm a bit of a gloomy person!
...But I don't want to get involved with her as much as possible. It's because she's possessed by a "ghost" that only I can see! --She's a little naughty, extremely pure and, in some cases, horrifying!
A romantic comedy about a "possessed" girlfriend and an "unlucky" me in a heartbeat is about to begin!
