Kinoko Komori, hero name Shemage, is a student in U.A. High School's Class 1-B. She stands 152 cm tall with light brown hair styled in a mushroom-shaped bob that frequently obscures her eyes; her pupils distinctly resemble cross-sliced shiitake mushrooms. Her hero costume displays a fly agaric mushroom pattern, includes a mushroom cap-shaped hat, knee-high boots, and a belt equipped with Shroom-Shooter spray bottles. Initially shy during the U.A. Sports Festival, Komori demonstrated growing confidence, notably in the Joint Training Battle. She enthusiastically wields her Quirk, often employing mushroom-related puns and applying affectionate honorifics to mushroom species' scientific names. She exhibits kindness by apologizing to opponents affected by her Quirk and providing medicinal relief. Komori admires pro hero Hawks and aspires to become an "Idol Hero" combining hero work with performance. Her personality also encompasses an appreciation for "kitsch" aesthetics and a protective attitude toward insects. Her Mushroom Quirk enables her to generate spores that rapidly grow into diverse fungi on any solid surface, including terrain and human bodies. These fungi typically last 2–3 hours and flourish in humid environments, aided by her moisture-dispersing Shroom-Shooters. Her Ultimate Move, Splitgill Lung Strike, grows fungi inside an opponent's respiratory system to induce choking. She exhibits versatility by producing multiple mushroom species, though external factors like fire or extreme dryness prevent spore growth. Classmates require antifungal spray to avoid unintended exposure. Komori was homeschooled during junior high due to difficulties controlling her Quirk, which caused accidental property damage and infections. This experience contributed to social reticence, later alleviated through friendships in Class 1-B, especially with Togaru Kamakiri. Her parents possess nature-themed Quirks—mother's Witch’s Butter (fungal substance generation) and father's Yard Spirit (soil manipulation)—which influenced her eccentric tastes. Key chronological events include participation in the U.A. Sports Festival’s Obstacle Race (34th place) and Cavalry Battle. She sustained critical injuries during the Forest Training Camp Vanguard Action Squad attack. In the Joint Training Battle, her fungi incapacitated Fumikage Tokoyami, securing her team's victory. She later partnered with Shihai Kuroiro for work studies. During the Paranormal Liberation War, she assisted the Gunga Mountain Villa assault, incapacitating villains with internal fungi until Dabi’s flames nullified her spores, and joined the sedative delivery effort against Gigantomachia. In the Final War, she fought at Gunga’s ruins but retreated when overwhelmed by Himiko Toga’s Twice doubles and Dabi’s flames. She survived All For One’s explosive attacks and continued providing combat support. Trivia includes her surname kanji meaning "small forest," given name kanji meaning "hope" and "child," and a homophone with "mushroom." Her hero name merges "shimeji" mushroom with "female mage," reflecting her witch-like costume. An unused hero name was "Gnocchi Nyokonyoko."
