Chiyo Shuzenji, operating under the alias Recovery Girl, holds the position of chief medical officer at U.A. High School, where her Quirk provides critical care for injuries across campus. Her diminutive frame features gray hair swept into a bun fastened by a syringe-shaped pin, complemented by a yellow-and-red-accented dress beneath her signature lab coat. She wields a syringe-themed cane and dons pink boots, her physical resilience visibly diminished after exhausting Quirk usage during the Paranormal Liberation War and Final War conflicts. Her Heal Quirk accelerates natural recovery via tactile contact—often administered through a kiss—but draws on the patient’s stamina, limiting its effectiveness without sufficient energy reserves. Critical cases demand conventional medical intervention first, exemplified by her emergency surgery on Izuku Midorya post-battle with Shoto Todoroki. To deter recklessness, she enforces strict boundaries, withholding treatment from Izuku until he demonstrated responsible control of One For All. Blending compassion with pragmatism, Recovery Girl openly critiques All Might’s instructional approach and chastises Izuku’s self-endangering tendencies. As one of few aware of All Might’s post-injury fragility and the secrets of One For All, she has treated his wounds following clashes with All For One. Her medical acumen transcends her Quirk, evident in surgical precision and tactical analyses during student exams, where she assessed combat efficiency and Quirk compatibility. Notable interventions include repairing Endeavor’s eye after a High-End Nomu confrontation, attempting to stabilize Sir Nighteye post-Shie Hassaikai raid, and coordinating recovery operations on Nabu Island following Nine’s assault. During the Final War, she provided triage from U.A.’s evacuation hub, her stamina waning under relentless demand. Post-conflict, she returned to U.A. duties while overseeing Gran Torino’s rehabilitation. Official evaluations reflect her non-combat specialization: minimal physical prowess offset by peak intelligence, technical mastery, and unmatched healing proficiency, cementing her role as U.A.’s strategic medical cornerstone.
