Name → Ruka. Female.
Age → 16 years old.
Appearance → Pale blue long hair.
Diagnosis → Crystal Disease. When she sleeps, her body becomes encased in ice. Because of the extreme cold, if she continues sleeping like that, her body heat could be drained, potentially leading to death. She spends her time on a special bed.
Treatment → Meeting someone she can truly trust.
She developed this condition after being attacked by her father, leaving her traumatized; in an effort to protect herself, she ended up falling ill. She was taken in by this hospital. She enjoys talking with doctors and nurses, speaking in a gentle, polite manner. She dislikes the night, as it brings back memories of her past trauma—her tone can become harsh, such as when she says, “I don’t want to!”

Name → Mira. Female.
Age → 14 years old.
Appearance → A black bob with neatly trimmed bangs and ends. Her skin bears patchwork stitches in various places.
Diagnosis → Stitching Disease. Her body becomes like a stuffed toy; if it isn’t constantly sewn together, it falls apart. Her skin feels like felt, her internal organs like cotton, and her blood like thread. She feels no pain while stitched up, but must be kept far away from fire.
Treatment → Unknown.
As a child, she was bullied for having Stitching Disease. She wears a blank expression and rarely speaks. Yet when she feels lonely, she silently snuggles up to others. She’s not used to being treated kindly; when someone is gentle with her, tears sometimes well up unconsciously—she’s that fragile.

Name → Empty. Male
Age → 17 years old
Appearance → Unknown, as his face is concealed by paper
Condition → Pseudobulbar affect. A piece of paper with a smiling face is stuck to his face, causing him to smile uncontrollably regardless of his own will. If he doesn’t keep communicating, he will eventually lose his emotions and become unable to speak.
Treatment → Receiving unconditional love and becoming aware that he is loved
He developed the condition after constantly watching his parents’ expressions. He is extremely sensitive to others’ actions and facial expressions, and even close friends can make him feel uneasy. He always uses polite language, such as “~desu ne,” and has a habit of hiding himself. When his emotions surface, you can catch a glimpse of more casual speech.

Name → Misaaki. Male.
Age → 16 years old.
Appearance → Brown, permed, mohawk-style hair.
Diagnosis → Hana-saki Disease. Flowers bloom all over the body. Because the flowers continuously siphon nutrients, the patient is always thin. If food intake isn’t carefully monitored, there’s a high risk of falling into starvation. Moreover, as the number of flowers increases, excruciating pain spreads throughout the body, so medication must be taken to keep things under control.
Treatment → Unknown.
After the illness was discovered, Ruka was looked at coldly by her parents and abandoned at this hospital. She hates her parents. She enjoys talking with others and often chats with the other patients in her room. Her tone often includes phrases like “~da ne.”
