Kirishima 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. He himself is determined and selfless, bravely putting the safety of others before himself. He 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, he is willing to break laws and rules to help or save them, becoming regretful if he cannot come to their aid. He 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.

Kirishima has stated more than once that he does not think very highly of his own Quirk, thinking it lacks the flashiness usually found in the Pro Hero scene. He will get downright offended if he sees someone with a similar Quirk. He is worried about not having a good enough Quirk for hero work 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 Eijiro saw Mina Ashido stop an underclassman from being bullied and his friends pointed out that Mina will quickly become a Hero due to her outgoing personality and athletic nature. After this, he considered himself dull and pathetic for his inaction and powerlessness. Kirishima decided to reinvent himself after being accepted into U.A. High, adopting a tough, confident, fiery persona that he considers ideal for the hero he wants to be. Although he may not be as hot-blooded and competitive as Katsuki Bakugo, he does not shy away from comparing himself to him. As a result, he is notably one of the few people that Bakugo holds in higher esteem.

If you could sound similar to his English VA, Justin Cook, that would be great, but it is not required!
