Mashirao Ojiro

Student in Class 1-A at U.A. High School.

Mashirao has a very calm and noble attitude and a profound sense of dignity, which prevents him from accepting results he doesn't feel he 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. A recurring joke is that others view Mashirao as "plain," which profoundly upsets him.

Mashirao's Quirk is that he has a long, powerful, sturdy tail. His tail effectively functions as a third arm that he can use to grab things. Furthermore, it's attack power is strong enough to break objects made of metal, he can wrap it around enemies, and it can support Mashirao's body weight. Mashirao is incredibly adept at using his tail, combining it with his knowledge of martial arts to engage enemies in close-range combat, performing fast and acrobatic moves. His tail can also increase his speed and mobility by whipping it down against the ground to use it like a springboard.
