Eijiro Kirishima

Eijiro's appearance is quite ordinary, except for his red-dyed hair, styled so that it resembles a cluster of small, sharp spikes. This isn't his natural hair color. He started dyeing it before entering UA. During middle school, his hairstyle was completely normal—straight, slightly tousled, black (natural) hair.
He has a scar above his right eye, which he acquired as a child after unexpectedly activating his Quirk. His teeth are sharply pointed, giving him a slightly aggressive appearance. Despite his young age, he also possesses an impressive build.

His hero costume consists of shoulder pads resembling cogwheels, baggy pants, and a belt with an "R"-shaped buckle, leaving his chest completely exposed. He also wears a mask that vaguely resembles a predator's jaw. Before the Hero License Exam, long, dark red sleeves are added to his costume to protect the people he rescues from his quirk.

Character
Eijiro sheds a stingy manly tear
Eijiro is a cheerful, boisterous, and outgoing guy. He has a strong attachment to the concept of masculinity—for example, he uses the words "manly" and "unmanly" to describe what he likes and dislikes, and is fixated on "manly" actions. Anyone who demonstrates bravery, nobility, or determination in his presence earns his boundless admiration and respect, and vice versa. He is also a big fan of the retro hero Scarlet Riot. He even chose his hero name in his honor.
Eijiro is honest, kind, and straightforward. Judging by the fact that he's one of the few who interacts normally with Bakugou, he makes friends easily. He's willing to do anything for his friends, even if it's just acquaintances, and he's very upset if he can't help them in some way.
