Mashirao Ojiro, a Class 1-A student at U.A. High School’s Hero Course, ascends to the rank of No. 32 Pro Hero after graduation. His innate Quirk, "Tail," provides a robust, prehensile appendage enhanced by martial arts mastery, forging a close-combat specialization. The tail’s hairless tip and dense musculature enable devastating strikes, agile mobility, and tactical defense, though prolonged exertion risks lower-body cramps.
Often underestimated for his unembellished Quirk and quiet disposition, Ojiro embodies calm humility tempered by unyielding honor. He rejects unmerited accolades, exemplified by his voluntary exit from the U.A. Sports Festival upon discovering Hitoshi Shinso’s brainwashing swayed his victory. This principled stance underscores his integrity, later mirrored in his reconciliation with Shinso to acknowledge mutual growth.
Academically, Ojiro secures 7th place in the Quirk Apprehension Test and 8th in midterms, demonstrating consistent physical and intellectual aptitude. Combat prowess shines during the U.S.J. crisis as he repels waves of villains solo, and in the Joint Training Battle, where he stalls adversaries like Sen Kaibara. Ectoplasm’s critique of his tail-dependent predictability drives Ojiro to innovate techniques, culminating in Ultimate Moves: Tornado Tail Dance, a whirling aerial assault, and Swamp Smack Spin, a defensive whirlwind to disperse threats.
Collaborative triumphs include partnering with Tenya Ida to outmaneuver Power Loader in Final Exams, and aiding Fumikage Tokoyami and Kyoka Jiro against Nine on Nabu Island. Training under Pro Hero Shishido sharpens his strategic foresight, refining his ability to counter enemy tactics.
Ojiro nurtures bonds with peers like Toru Hagakure, offering solace during her vulnerabilities, and Denki Kaminari, whose playful tail interactions mask mutual respect. He admires Izuku Midoriya’s tenacity, advising him on Shinso’s Quirk while valuing Midoriya’s Sports Festival encouragement. A Maibiki Middle School alumnus, Ojiro’s martial arts dedication informs his hero costume’s evolution from a traditional karate gi to a sleek inverted black-and-white design with communication gear.
In *My Hero Academia: Smash!!*, he serves as lighthearted contrast to his earnest main-series role. Post-Final War, a left-cheek scar symbolizes his enduring resolve to transcend perceptions of "ordinary," channeling relentless effort to redefine strength through quiet perseverance.
