Moe Kamiji, known as Burnin, works as a Pro Hero and key sidekick in Endeavor's agency, marked by her energetic personality and signature flaming green hair. Her Blazing Hair Quirk enables her to manipulate fire from her hair for attacks and propulsion flight, sometimes forming flame spears in combat. She stands 169 cm tall with sharp eyes and pointed teeth, wearing a light-gray costume that includes a temperature-gauge belt, a back-mounted fire extinguisher, black knee-high socks, and boots; her costume sees only minor boot changes post-timeskip. Burnin displays an enthusiastic, direct, and competitive nature, frequently clashing with Katsuki Bakugo due to their similar fiery temperaments. She shows strong loyalty to Endeavor and her team, revealing emotional vulnerability in critical moments, like distress over fallen comrades. Her leadership skills involve coordinating evacuations and hero deployments during emergencies. Her background includes joining Endeavor's "Flaming Sidekickers" before the main series. During the Vigilantes spin-off, she participates in Endeavor's operation against villain Bee☆Pop in Naruhata, signaling for Hellfire Storm attacks. She later aids during the Nomu-triggered Naruhata Lockdown, witnessing All Might and Endeavor's joint intervention. In the Endeavor Agency Arc, she greets intern trainees Izuku Midoriya, Shoto Todoroki, and Katsuki Bakugo, stressing the agency's competitive environment. She later acknowledges their resolve through their damaged costumes and supports their training under Endeavor as Paranormal Liberation Front threats escalate. During the Paranormal Liberation War, Burnin directs civilian evacuations near Jaku Hospital. After Tomura Shigaraki's Decay quirk ravages the area, she manages retreats and hero communications. She later fights Near High-End Nomu reinforcing Shigaraki, suffering heavy team losses before Mirio Togata rescues her from an ambush. In *World Heroes' Mission*, she joins Endeavor's global task force against Humarise in Otheon. When Humarise activates Trigger Bombs, she assists Endeavor in securing one bomb by holding off cult members while he launches it skyward, trusting Midoriya's team to disarm the weapons worldwide. In the Final War Arc, Burnin backs Shoto Todoroki against Dabi and engages in large-scale battles against All For One's forces. She appears at the conflict's end and attends a post-victory hero gathering. Her development shows growing respect for Endeavor's dedication and evolution into a dependable field commander. She maintains a friendly rapport with Shoto Todoroki, addressing him informally, and expresses concern for colleague safety during missions.
