I know this is a great opportunity. And I know how stupid it must seem to throw it away... but this final tournament... everyone else made it here by their own strength. Yet I'm standing here, and I don't even know how or why. I just can't take it.
Mashirao Ojiro quitting the U.A. Sports Festival in "Smile, Prince of Nonsense Land!"

Mashirao Ojiro ( () (じろ) (ましら) () Ojiro Mashirao?), also known as the Martial Arts Hero: Tailman, is a student in Class 1-A at U.A. High School, training to become a Pro Hero.


Mashirao is a young man of muscular build, and has short blond hair, swept to the front of his head. He has thin eyes with no lower eyelashes, and a thick, long tail with a hairy tip. Unlike the other students in his class, he wears pale gray sneakers with his school uniform instead of the brown dress shoes worn by everyone else, and the bottom button of his blazer he leaves casually undone.

Mashirao's hero costume is a plain karate gi, tied with a black belt, its collar partially lined with fur.

Before the Provisional Hero License Exam Arc, his costume recieves a slight upgrade, now including navy blue fingerless gloves.



Mashirao has a very calm and noble attitude as well as a very deep sense of dignity, which prevents him from accepting results that he doesn't feel were earned with his own abilities. He is also described as a hard worker.

Along with a strong sense of dignity, Mashirao can be described as sheepish and bashful, not very often enjoying the spotlight and being easily embarrassed. However, has also been shown to be very sweet and humble, as he is a very caring and empathetic person when it comes to the emotions and well-being of other people. He is also very sensitive and soft-hearted, as his feelings be hurt very easily, such as when his room is called "normal" as it upsets him to some extent.

When something excites him, he wags his tail, in a similar fashion to a dog, though this is only ever seen in the manga.


Overall Abilities: Given his epithet, Martial Arts Hero, it can be assumed that Mashirao is a highly capable combatant. His skills allowed him to earn 7th place in the Quirk Apprehension Test. Mashirao mostly relies on hand-to-hand combat during battles and makes use of his Quirk during close quarters combat. According to Ectoplasm, Mashirao relying on the use of his tail makes him predictable opponent that can easily be exploited. To eliminate this factor, Mashirao improved the fundamentals of his movements to become less predictable in combat.

During the Joint Training Arc, he held his own against Sen Kaibara, who was holding back, but was almost overwhelmed by the latter’s onslaught, had it not been for the intervention of Tenya Iida. Even after receiving minor injuries from his bout with Sen, Mashirao was able to successfully subdue Pony Tsunotori, the fastest student in Class 1-B, who has battling against Mezo Shoji.

Keen Intellect: Mashirao is known to be quite intelligent, scoring 8th place in the midterms, displaying his skill in academics.


Tail (尻尾 (しっぽ) Shippo?): Mashirao's Quirk gives him a strong, sturdy tail. He is incredibly adept at using it, having demonstrated creative abilities, such as whipping it down against the ground to give himself a speed boost. As part of his training, Mashirao continuously used his tail to attack a body-hardened Eijiro Kirishima, and with each hit, the strength and durability of Mashirao's Quirk increased.
