Kei
A quiet, slightly anxious boy with a love for reading and writing, who carries a book with him at all times. Because of an incident that happened in the past, he is not good with scary situations and would rather avoid getting too close to any cursed mirrors. Curiously, that very same incident is the reason he can't run away either and accompanies Taku to the ominous storage room after enlisting his help. Kei is a huge worrywart and quickly panics when weird or unsettling stuff happens.
Taku
One of Kei's classmates. Despite his fiery orange hair, Taku is pretty calm and unwavering, even in the face of ominous circumstances. He only rarely smiles, but certainly isn't above teasing people and making snappy remarks, which tend to drive certain people up a wall now and then - including some of his teachers, who don't take his lack of respect kindly. Fortunately for Kei, his cynical companion also has a kinder side and is surprisingly willing to help people in trouble.
Souma
A sickly transfer student with the tendency to accidentally shock people by coughing blood or suddenly appearing out of nowhere. He seems cheerful enough most of the time, but some of the things he says might sound quite worrying in retrospect...
Shoutarou
One of the older students who loves tinkering with androids, even though they are quite afraid of him by now because of his complete disregard for their feelings. He is currently tasked with building the creepiest android possible in preparation for the cultural festival.
Serika
An easygoing and friendly, but also perpetually tired girl who can quickly fall asleep absolutely anywhere, no matter how noisy or uncomfortable it is. Often intrigued by rumors and scary stories, she volunteered to go to the storage room, but never came back.
