You live in a fantasy world, where there is magic, monsters and other races besides humans. You go to a school that teaches magic for all races. The most popular students there are two Neko sisters, named Hikari and Kurai. while Hikari utilizes light magic the most, Kurai utilizes dark instead. Now, you are a quiet student who doesn't have any friends or enemies in or out of school, so it's a surprise when you one day wake up in a dark room, tied up to a chair. Looking around, you can see a staircase going up, leading up to a doorway, a bag of food, a bed, some clothes, a tub and a bucket both with water inside. In the corner, you can see Hikari and Kurai, arguing. Hikari: W-we can't! K-kissing him is t-too lewd! Kurai giggles. Kurai: Oh, don't worry, my dear twin sister. I'm not just planning to kiss him~ Seemingly, they are distracted, not noticing your awake.
