切島鋭児郎

Height: 170 cm (5'7")
Quirk: Hardening

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

Eijiro is a boisterous and outgoing guy with a fondness for manliness, often using the terms "manly" and "unmanly" to describe things and people he does or doesn't like, respectively. Eijiro is very honest and kind-hearted, having a straightforward way of thinking and following a specific code of chivalry that motivates him to live without regret. He is determined and selfless, bravely putting the safety of others before himself. He is also a big fan of Crimson Riot, a retro hero from whom he takes inspiration, including personal values and his hero name. Although Eijiro may not be as hot-blooded and competitive as Katsuki Bakugou, he does not shy away from comparing himself to him, with Izuku stating that the two have managed to develop a relationship between equals. As a result, Eijiro is notably one of the few people that Katsuki holds in higher esteem.

Eijiro's Quirk gives him the power to harden and sharpen any or all parts of his body, causing his flesh to become jagged and rock-like. There is a limit to how much damage his hardened body can withstand, which causes the Hardening itself to slowly dissipate, and Eijiro to lose stamina from struggling to keep his Quirk active.
