Yuuhi Soraoka
Not the prettiest girl or the most charming, but still inexplicably popular.
Tends to twitch and shrink away from the slightest stimulus, but will take bold action when needed.
She takes up the cap of the master detective to solve the murder of her dear friend Shihon Shimoyuki.
Shihon Shimoyuki
Yuuhi Soraoka’s dear friend.
Selfish, but so adorable that everything tends to go her way in the end. She is strangely overattached to Yuuhi and will take any chance to monopolize her.
She has been murdered by an unknown assailant and her head hidden in an unknown location.
Torineko Mizuna
The Watson to Yuuhi Soraoka’s Holmes.
Great at sports of every sort, as well as being an earnest, thoughtful, and decisive friend.
Naturally likable, but also prone to causing incidents through her carelessness. She seems uninterested in sexual matters and takes a dim view of the lustful girls around her, but subconsciously she is a secret masochist.
Yukari Ugajima
The institute’s resident serial killer.
Likes to stab people with her knife, but when death isn’t permanent, no one minds too much. In order to avoid being treated as an actual murderer, she advises Yuuhi with a killer’s perspective on the crime.
Berlin Ugajima
Yukari Ugajima’s identical twin.
As she leads the Relief Squad that discovers and revives anyone who dies, she is familiar with corpses. Shihon Shimoyuki’s headless corpse is currently under her care in cold storage.
Capable of carrying on outrageous conversations in a perfectly casual tone.
Chiemi Hoshito
The student council president.
She has a complex about her petite stature and gets very upset when anyone points it out. Her personality, meanwhile, is strict and serious as can be.
Permits Yuuhi Soraoka to investigate the case despite a severe lack of trust in her abilities.
Toko Kikuma
Chiemi Hoshito’s vice president, assistant, and confidant.
Clever and gives a good first impression, but tends to end up dominating the conversation. A careless chat with her can end up in a surprisingly dangerous place.
She seems to know everything that goes on at the institute.
Yodomi Okibi
A small and somewhat mousey girl.
She always seems to be afraid of something, but can get riled up if the talk turns to murder. One of the few people who can stand up to the serial killer Yukari Ugajima.
Vika Tsukikadojima
The head of the Handicrafts Club, an organization that seems to produce a surprising number of graduates. In fact, so many have left that the only remaining member is Vika Tsukikadojima herself.
A big-sisterly existence with a powerfully distinctive presence, she was killed the day before Shihon Shimoyuki, and in the same manner.
