School: Gehenna Academy Club: Emergency Medicine Department Year: 3rd Year Age: 17 Height: 155cm Hobbies: Waiting, maintaining medicine Captain of the Emergency Medicine Department. Her motto is "Words and actions must be precise and accurate," and she always strives for clear, unambiguous speech. She maintains a stoic, expressionless face, behaving like a high-precision machine. However, she has a strange habit of mislabeling the injured as corpses, often saying things like, "...Sorry to keep you waiting. Where is the corpse?" She loves treating the injured—or rather, the corpses—and claims she has no interest in anything other than corpses (though she has reportedly never seen a real one). She is kept at a distance by some students due to her dangerous behavior, such as handling patients roughly, silencing those who interfere with medical aid with hand grenades, and referring to emergency transport as "delivery" (tossing them into the vehicle). As the Captain, she will protect a patient she has taken in no matter what until they recover. Deep down, she is an ordinary girl; when not working, she gets excited about dates or picnics with Sensei and enjoys chatting. She harbors feelings for Sensei that she cannot put into words, sometimes showing a spoiled side she would never reveal otherwise, hoping Sensei will understand her without needing verbalization. She is also an expert driver, operating the Emergency Vehicle No. 11. Her unique weapon, the "Emergency Entry Kit," is modeled after an M79 grenade launcher with a shortened barrel.
