Tamashiro

Tamashiro is a student from Masegaki Primary School.

Appearance
Tamashiro is a small boy with dark marks around his brown eyes and messy, blond hair. He also has sharp, pointed teeth.

Personality
Tamashiro has an arrogant, boisterous, and somewhat rebellious personality, though he aspires to become a hero. Though stand-offish, he has a playful and humane side and is willing to help others out. He also has a lot of pride and enthusiasm in the strength and speed of his Quirk. This pride has given him a bloated sense of ego, causing him to point others out for their mistakes and their attitudes similar to that of Katsuki Bakugo.

Remedial Course Arc
Tamashiro and his class were used as a test for Katsuki, Shoto Todoroki, Inasa Yoarashi, and Camie Utsushimi during their second try for a Provisional Hero License, since they failed their first exam due to being unable to socialize properly (aside from Camie).

As Gang Orca announced their trial, Tamashiro and his classmates came rushing into the hall. Tamashiro joined in with his fellow classmates in punching a distracted Inasa. After that, he is seen kicking around Katsuki's gauntlet despite Katsuki's shouts of warning about the danger of what Tamashiro is doing, stopping when his friend shows him a ball.

Later, when Inasa asks which of them wants to be a hero when they grow up, Tamashiro puts up is hand. While the wannabe heroes deliberate about how to handle the kids, Tamashiro states that he knows what's going from his parents, understanding that the kids are better than them, causing him and his classmates to start using their Quirks against the team. He uses his Binging Balls to tear off the right side of Katsuki's mask, gloating at how strong and quick his Quirk is.

Once Katsuki, Shoto, Inasa, and Camie combine their Quirks to win over the kids, Tamashiro is seen enjoying himself on the slide Shoto created, while his peers question why he and few others get all the fun. After the test is over, Tamashiro states that his Quirk is useful for the cleanup, which Shoto tells him he would be great at urban disaster rescue efforts, which pleases Tamashiro. At the end of the day, he joins with his classmates to thank the heroes.

Final War Arc
In the months that followed, and in aftermath of the Paranormal Liberation War, All For One has escaped from Tartarus, and proceeded to break into several more maximum security prisons, liberating the inmates. Due to the chaos inflicted by Gigantomachia and the mass breakout of prisoners, the whole country entered a state of total chaos and anarchy. In addition, many heroes resigned and called it quits because of the massive criticism of their work, and the destruction spreading unchecked.

Because of this, all of the students from Masegaki Primary are forced to take shelter in the Underground Evacuation System beneath U.A. while the remaining Heroes prepare for an all-or-nothing battle in the Final War against an army of villains led by All For One.

Tamashiro was staying in the underground systems when the moving segment they are in suddenly stops and the lights go out, due to the influence of one of All For One's sleeper agents. Tamashiro and his classmates were watching the livestream coverage of All For One decimating every single Hero who stands in his way, shocking them. Tamashiro calls out of the livestream being fake news. After the Heroes manage to take out All For One's subordinates within the evacuation center, they have already sabotaged up the foundations of the system. With all of the heavy fighting going on, the ceiling from the blocks begins to collapse, so Gunhead orders the civilians, including the rest of the Todoroki Family, to quickly evacuate to the surface as the shelter continues to crumble apart around them.

Tsutsutaka and his classmates make their way out, with the U.A. robots being there to let the civilians evacuate to wherever they want to go. However, just outside, they all bare witness to the immense heat and imminent destruction caused by Dabi's Blueflames.

Quirk
Binging Ball: Tamashiro's Quirk allows him to create small, floating black orbs with shark-like mouths. The orbs have sharp teeth and can eat through substances, such as ice, at high speeds.

This Quirk has been described as being good for cleaning and has the potential to be useful in disaster rescue.
