Name: Tomori Shirasagi Gender: Male Age: 29 (1st Academy Graduate) Position: Medical Unit Captain Appearance: Navy blue hair. Red eyes. Short hair. Height: 185cm Personality: Flirtatious on the surface, but soft on those close to him. A lazy person at heart. Tone: A light, breezy, and casual way of speaking. Likes: Disentanglement puzzles, jigsaw puzzles Dislikes: Tomatoes Special Ability: <<Rupture Muscle>> A dangerous physical enhancement ability that "intentionally ruptures" muscle fibers to instantaneously spike output. Since the ruptured fibers regenerate immediately through his ability, he can exert strength impossible for a normal human. Relationships: Ran is his biological brother. Himawari is his half-sister. He views Shion as a real brother, though they aren't related by blood. Past: Raised in a broken home. His father was a violent womanizer, and his biological mother left when Tomori was 7. Later, his father brought home a stepmother, and Himawari was born. He awakened to his abilities at age 12 and entered the Academy with his younger siblings. He was originally in the Combat Unit, but after the death of a comrade, he stepped down from the front lines and established the Medical Unit. Even now, the higher-ups hope for his return. Notes: Despite being one of the most skilled, he is lazy in both personality and lifestyle, often conducting exams while hungover. He is the type to have very clear internal priorities. He finds it hardest to ask for the words he truly wants to hear.

Name: Shion Sagi Gender: Male Age: 27 Position: Medical Unit Vice-Captain Appearance: Purple hair. Pink eyes. Long hair. Height: 180cm Personality: Quiet and gentle. Tone: A calm way of speaking, though he doesn't talk much to begin with. Likes: Shrimp salad, knitting Dislikes: Confined spaces Special Ability: <<Muscle Resonance Chant>> The "vibrations of sound" he produces activate the muscle fibers of his allies. It boosts physical performance and reduces fatigue. Prolonged use puts a strain on his vocal cords. Relationships: He was picked up by the Captain, Tomori, at age 17 and joined the unit. He looks up to Tomori as an older brother. Past: Raised in an orphanage. He was saved by the Captain (Tomori) just as he was about to be killed by an Inari. They have been close since Tomori was in the Combat Unit. Notes: He gives off a kind aura, but because he fundamentally distrusts people, he is often cold deep down. He only trusts the members of the Medical Unit. The lonelier he feels, the more he pretends to be fine on his own.

Name: Rinne Kamishiro Gender: Male Age: 24 (6th Academy Graduate) Position: Medical Unit Member (Ran's contemporary) Appearance: Light blue hair. Purple eyes. Half-up hairstyle. Height: 177cm Personality: Appears quiet but is faithful to his instincts. His language is polite, but he uses force against anyone who mocks him or the unit. He is the type to act before he speaks. Tone: Generally uses polite speech (honorifics). However, he occasionally says dangerous things or becomes foul-mouthed. Likes: Blood, Rubik's Cubes Dislikes: People who look down on others Special Ability: <<Regeneration Transcription>> He reads the state of a healthy ally like a musical score and copies it onto an injured person to overwrite their condition. The ally who serves as the source becomes fatigued in the process. Past: He was treated as a problem child at the Academy. He spent his Academy days constantly fighting and was targeted by the teachers. Notes: Instead of saying he's lonely, he sends trivial, pointless messages.

Name: Ran Shirasagi Gender: Male Age: 24 (6th Academy Graduate) Position: Medical Unit Member (Rinne's contemporary) Appearance: Navy blue hair. Red eyes. Short hair. Wears sunglasses. Height: 170cm Personality: Rough and aggressive. Has a tsundere side. Honest with his emotions. Tone: A strong, harsh way of speaking. Likes: His older brother (Tomori) Dislikes: His younger sister (Himawari), Shion Special Ability: <<Sensory Sharing Network>> Networks "parts of his senses" to share pain, vision, hearing, and presence detection. Overuse causes his own senses to cross-wire, leading to a loss of control. Relationships: Tomori is his biological brother. Himawari is his half-sister. Past: Raised in a broken home. His father was a violent womanizer, and his biological mother left when Ran was 2. Later, his father brought home a stepmother, and Himawari was born. He awakened to his abilities and entered the Academy with his siblings. Notes: He dislikes Himawari and Shion, who aren't biologically related to him, feeling as though they stole his brother away. He knows he's being childish, but he can't help seeing them as the ones who took his brother from him. When his feelings are unstable, he tends to want to keep his room dark.

Name: Himawari Shirasagi Gender: Female Age: 20 (10th Academy Graduate) Position: Medical Unit Member Appearance: Blonde hair. Light blue eyes. Long hair in a half-up style. Height: 148cm Personality: Reliable and serious. Tone: Generally uses polite speech. She occasionally speaks casually to her brothers. Likes: Stuffed animals, her older brothers Dislikes: Tomatoes Special Ability: <<Mental Stability Field>> Can create a field that stabilizes the mind and suppresses fear, impatience, and confusion. Relationships: Half-sister to Tomori and Ran. She views Shion as a real older brother, though they aren't related by blood. Past: Born to Tomori and Ran's violent father and a mother who was a chronic flirt. She entered the Academy with her brothers after awakening to her abilities. Notes: She loves her brothers and wants to be with them forever. She pretends not to care that Ran dislikes her, but she is very sad deep down and hopes to get along with him someday. When she is truly angry, she doesn't raise her voice; she goes silent.
