Kōji Kōda, hero name Anima, studies in U.A. High's Class 1-A. Born on February 1 in Iwate Prefecture, he inherits a heteromorphic appearance from his mother, marked by animal-like horns that emerge as he matures. His Quirk, Anivoice, grants him the ability to communicate with and command animals—a power passed down from his mother, who urged him to embrace it despite societal prejudices against heteromorphs. Kōda’s imposing frame combines a tall, muscular build with peach-toned skin and a head resembling rugged stone. His initial hero costume—a yellow suit adorned with red accents—gains a voice-amplifying full-face mask during the Provisional License Exam. After the Final War, his horns expand into a crown-like formation, boosting his telepathic connection to animals, while his costume evolves to feature a streamlined strap design instead of the mask. Contrasting his formidable look, Kōda radiates quiet timidity, often opting for sign language over speech—a habit that once led Kyoka Jiro to assume he was mute. His gentle spirit mirrors his devotion to animals, embodied by his cherished rabbit companion, Yuwai-chan. Though harboring a fear of insects, he conquers this phobia in pivotal battles, commanding swarms to triumph over adversaries like Present Mic during the Final Exams. Anivoice empowers Kōda to direct animals in reconnaissance, diversionary tactics, or assaults. Originally dependent on spoken orders, his Quirk undergoes a transformation amid the Final War—enhanced by his crown-like horns, it unlocks silent telepathic control across vast ranges. Stress and determination ignite this awakening, enabling covert animal coordination. Signature moves like Hitchcock Birds deploy avian flocks to obstruct foes, while Bugging Out unleashes insect hordes to overpower enemies. At the Provisional License Exam, Kōda demonstrates tactical growth by deploying disorienting bird formations, signaling his honed Quirk control. Training under the pro hero Wash sharpens his communicative precision. The Jaku Hospital clash becomes a turning point—fueled by determination to shield fellow heteromorphs, he triggers a Quirk awakening that amplifies his command, uniting varied animal species against threats. Alliances shape Kōda's path: a bond with Fumikage Tokoyami sparks during the USJ crisis, while teamwork with Rikido Sato strengthens in joint missions. Kyoka Jiro's support catalyzes his courage, fostering reciprocal growth. His U.A. dorm room, alive with animal-themed decor, mirrors his serene, nature-aligned ethos. After graduation, he allies with Mezo Shoji (Tentacole) as a pro hero sidekick, embodying perseverance through his evolution from reticent scholar to assured leader harnessing Anivoice's zenith.
