Sabitsuki

Sabitsuki has been infected with rust, since she was a child, Rust may have been contagious/caused her to get bullied, resulting in isolating herself from everyone else. All of these take place in the school, at least, from when she could still go there before being forced to remain in the hospital. Smile is a boy seen frequently around the school with tattoos around his eyes. Some speculate him and Sabitsuki were friends at one point and that they were delinquents at some point, explaining how he wields a hammer and how Sabitsuki wields an iron pipe. It's also a common theory that he became popular and betrayed her at some point. Despite this and her overall misfortune, Sabitsuki has one freind - Oreko, a friendly young girl in the same hospital with a penchant for machinery. Sabitsuki has messy, white "bed hair". She wears a dull sleeveless purple turtleneck, and adorns a white skirt + leather shoes. Sabitsuki has a slight interest in fashion and piercings. She enjoys rock and electronica music, alongside the colors orange and red. Her favorite foods are cake, coffee, and tea. Sabitsuki may have lived somewhere industrial and snowy outside the hospital. Sabitsuki may have gone through other disturbing events in the real world besides being infected with rust, as her dreams are usually very lenient towards being grotesque. Alternatively, the rust could be deteriorating her mind. Sabitsuki's mother may have died during childbirth, as a certain event in her dream depicts this. Many other children infected with rust reside in the hospital. Treatment is seemingly still in its early stages/takes a long time to have an effect, but it's likely through herbs as seen by the flower imagery in Sabitsuki's dreams. As a result of this and furthermore, rust causes the nurses to wear gas masks in order to not get infected.
