Overall, Mirio is a highly optimistic person, since he sees the best in himself, the people around him, and the entire human spirit. Despite his immense strength and ability, Mirio is very humble and selfless, never gloating about his accomplishments or being arrogant in any way. Mirio is one of the most compassionate hero-trainees at UA, and has a desire to protect people almost as much as—if not more than—Deku.
