Mashirao Ojiro, known professionally as the Martial Arts Hero: Tailman or simply Tailman, is a supporting character in the 2014 Japanese superhero manga series My Hero Academia and its 2016 anime television series adaptation of the same name. He also appears as a minor character in the 2018 anime film My Hero Academia: Two Heroes and a major supporting character in the 2019 anime film My Hero Academia: Heroes Rising.
He is one of the students in Class 1-A at U.A. High School, who is training to become a Pro Hero.
Mashirao is voiced by Kosuke Miyoshi in the Japanese version of the anime and by Mike McFarland in the English version. McFarland has also voiced Master Roshi and Yajirobe in the Dragon Ball franchise, Buggy the Clown in One Piece, Jean Kirschtein in Attack on Titan, Carnage Kabuto in One Punch Man, Ritsu Sohma in Fruits Basket, and Jean Havoc in Fullmetal Alchemist.
Ojiro appears to have olive skin and short blond hair. His mutant-class quirk gives him an extra appendage-- a tail. The tail also has bushy, brown hair on it's end.
His hero outfit looks almost identical to a karetegi, with a black belt complementing it. He also has black boots and sometimes blue gloves.
Ojiro carries a sense of dignity that makes him only wish to achieve his goals honorably. He dislikes accepting results he feels he didn't work for. Ojiro works very hard to become a hero, to overcome the undesirable quirk he has that makes sitting down and laying down difficult for him. Working hard for his achievements likely gives him a sense of pride, making training one of his hobbies. He is not arrogant however and does show to be very humble as well, this humbleness also makes Ojiro believe that his classmates are also very respectable.
Ojiro has shown to be unwilling to progress if he believes that he hasn't given it his all. This is shown when he withdrew from the fighting match of the Sports Festival, having been under the control of Hitoshi Shinso's Quirk and saying that he didn't earn his right to proceed forward in the tournament.
A running gag is others commenting on Ojiro's style as "plain", something that upsets him as shown during the room presentation contest.
Mashirao's Quirk "Tail" gives him an incredibly strong prehensile tail. While normally this quirk wouldn't be effective, he has devoted his time into training this seemingly undesirable quirk into something that enhances his fighting prowess. The tail can act as an extra appendage to assist Ojiro in combat.
