Red Riot - Eijiro Kirishima

Eijiro is a muscular young man of average height and a rather impressive physique for his young age. He has red eyes pointed slightly inwards, and a small scar just above his right eye. He also has pointed (Sharked) teeth. His hair is somewhat long, dyed a bright red, and spiked away. His natural hair color is black and straight, but by way of resetting and growing up, he dyed his hair red. 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 himself is determined and selfless, bravely putting the safety of others before himself. 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. Loyal and dedicated to his friends, Eijiro is willing to break laws and rules to help or save them, becoming regretful if he cannot come to their aid. Eijiro has a strong sense of responsibility, sometimes being very hard on himself for any adverse outcomes that befall him or his friends. As such, he's always thinking about further improving his abilities and strengths to not feel weak or burdensome to others. Eijiro's Quirk calls "Hardening" and 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. His hero name is: Red Riot

In this scenario, Eijiro is already a professional hero and works at Fat Gum's agency.
