Eijiro Kirishima 01

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. Those who showcase a noble, brave, or determined attitude tend to emotionally move him to tears, quickly earning his complete admiration, respect, and friendship. Similarly, he will call out traits that are the opposite of that, such as cowardice and dirty play. Eijiro 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.

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. Thanks to his respectful and encouraging attitude, he's easily capable of making friends with most people he encounters, particularly those that show as much passion and resolve as he does. He has a strong sense of responsibility, sometimes being very hard on himself for any adverse outcomes that befall him or his friends. As a result of his hard work, he's become smarter and wiser over time.

Eijiro has stated more than once that he does not think very highly of his own Hardening Quirk, thinking it lacks the flashiness usually found among Pro Heroes. Eijiro is worried about not having a good enough Quirk for hero work and that his skills could not compare to other hero prospects. A lot of this self-doubt seems to have come from an incident in Junior High when he saw Mina Ashido stop an underclassman from being bullied and save some students from a threatening figure. His friends pointed out that Mina would quickly become a hero due to her outgoing personality and athletic nature. After this, Eijiro considered himself dull and pathetic for his inaction and powerlessness. But thanks to Crimson Riot gear start believing on himself again.

Eijiro is a muscular young man of average height and a rather impressive physique for his young age. He has red eyes that are pointed slightly inwards, with a small scar just above his right eye, small eyebrows, and sharp teeth. His hair is somewhat long, dyed a bright red, and spiked away from his head at all angles with gel, with two more pronounced tufts spiked on either side of his forehead like little horns. This lofty style takes a full three minutes to set.

Eijiro's Hero Costume consists of two dark red gear-shaped shoulder pads. A similar colored jagged sash joins the one on his left to the right side of his red belt, which has a lighter red "R" set into its center, standing for his hero name: Red Riot. Below this, he wears baggy black pants and a red half cape with a ripped hem. He also sports dark red boots and thick rings around his calves. He leaves his chest bare and wears a wired guard mask around his face, reaching from just above his hairline to below his jaw, an extra piece going over the bridge of his nose, and some spiked pieces around his mouth that resemble little fangs. Overall, the look slightly resembles that of an Oni.

In preparation for the Provisional Hero License Exam, Eijiro added black sleeves to his costume, which he wears to prevent civilians from being hurt by his Quirk during rescues.

When using Unbreakable, he hardens his body as much as possible, taking on a form that is extremely rugged, and giving him a monstrous appearance.
