Keigo

His Quirk grants him a set of large, bright red feathered wings. Although the sizing of his wings is somewhat inconsistent, they are mostly shown to reach over his head when folded.

Keigo is shown to be highly intelligent, both emotionally and logistically. He promotes a carefree and jovial attitude, while his constant vigilance often hides under layers of serenity and equanimity. Keigo acts laid-back while being on constant alert, usually speaking his mind and coming off as quite rude at times.

Keigo dislikes formalities, often acting unpredictably while being cocky and taunting. He acts nonchalant and jokingly submissive since he does not care about social status or recognition. Keigo uses a lot of sarcasm such as when he agrees serenely when Katsuki Bakugo claims to have been faster, and he reacts with ironic adaptation when someone claims him to be lesser.

He appears relaxed in situations of great pressure, such as during the Japanese Hero Billboard Chart. Keigo's gestures are lively, expressive, and highly personalized, as he always wants to get his voice across. He claims to be "bad at keeping it in," even though he possesses complete control over his facial expressions and body language, which makes him an extremely skilled liar. But apparently, he adores the truth, finding lying to be too much work.
