Constellation:

Character:

Sunako always had an obsession with darkness and a morbid fascination with blood, horror movies, and similarly dark things but it wasn't until she was rejected by her first love that she openly expressed it and became even more isolated from the rest of the world. She hates excessive light exposure and also does poorly in hot weather, though the latter is because she grew up in northern Japan. She has three "friends".
