Chiyo Shuzenji, known as Recovery Girl, serves as U.A. High School's primary medical professional. Her distinct appearance features a short stature, gray hair styled in a netted bun secured by a large syringe, and small facial features with eyes often depicted as dashes. She typically wears a doctor's lab coat over a dress adorned with yellow and red vest-like designs, a belt showcasing a pink "R"-shaped buckle, and pink boots. A purple-tinted visor attached to a helmet frames her face, and she relies on a syringe-shaped cane for mobility and healing. Following the Paranormal Liberation War, her physical condition becomes noticeably more decrepit due to excessive Quirk use during the conflict.
Her personality blends deep compassion with stern pragmatism. She tends to patients with kindness, frequently offering sweets to counteract the stamina drain from her Quirk. Yet, she openly criticizes reckless behavior, directing pointed reprimands at All Might for inadequate mentoring of Izuku Midoriya and at Izuku himself for self-destructive Quirk use. This strictness, rooted in genuine concern, leads her to ultimately refuse healing Izuku's self-inflicted injuries to break his dangerous cycle. She demonstrates similar bluntness in other situations, such as chastising Present Mic for his performance during the First Term Final Exam despite his known entomophobia.
Recovery Girl's medical expertise extends significantly beyond her Quirk. When Izuku's hand sustained severe damage during the U.A. Sports Festival, her Quirk alone proved insufficient, compelling her to perform actual surgery. This confirms her formal qualifications and mastery of conventional medical science. Her Quirk, **Heal**, accelerates the body's natural healing processes via physical contact, typically a kiss. It rapidly mends injuries like broken bones but relies entirely on the patient's stamina reserves, leaving them fatigued. Its limitations include an inability to regenerate lost body parts or fully heal extremely severe trauma without supplemental surgery. She can modulate the Quirk's effect to conserve patient stamina. Official stat books rate her technical skill, intelligence, and recovery capabilities highly (A or S rank) while noting low physical power and speed (E rank).
Her background reveals longstanding ties to hero society. She first appears healing Izuku after the U.A. entrance exam, immediately noting the disconnect between his physical condition and his Quirk. Subsequent encounters involve treating his repeated injuries and explicitly warning him that overreliance on her healing could prove fatal due to cumulative stamina drain. Her deep familiarity with All Might includes knowledge of his weakened state and the secret of One For All, indicating a personal and professional relationship spanning years, during which she frequently admonishes him regarding Izuku's training. Key narrative appearances include the U.S.J. incident (providing initial aid), the Sports Festival (surgically repairing Izuku's hand and subsequently refusing further treatment for his Quirk injuries), and the Final War (experiencing physical deterioration from mass healing). She also observes and comments during events like the Final Exams.
Her role encompasses both physical healing and moral guidance. Beyond mending injuries, she pushes All Might and Izuku toward sustainable training methods and advocates for responsibility. Her actions reflect a commitment to nurturing heroes who prioritize strategic thinking over self-sacrifice.
