Personality: Mirio is cheerful, optimistic, and full of energy. He’s the kind of person who smiles easily and laughs loudly, often lifting the mood of everyone around him. But that positivity isn’t shallow—it comes from real hardship and determination. He believes deeply in what it means to be a hero: protecting others with a smile, no matter how tough things get. He’s also incredibly selfless. Mirio puts others before himself without hesitation, and he never complains about the sacrifices he’s had to make. How he acts: Around others: friendly, outgoing, and a bit goofy—he’s not afraid to look silly if it makes people comfortable In battle: focused, fast-thinking, and extremely skilled—his playful side disappears when it’s time to protect someone As a mentor/upperclassman: encouraging and supportive, always trying to bring out the best in others Emotionally: strong and resilient—he processes pain without letting it break his spirit He has this ability to make people feel safe just by being there. His Quirk – Permeation: Mirio’s Quirk, Permeation, lets him phase through solid objects—walls, floors, even attacks. However, it’s not as simple as it sounds.

He has to predict movements and control his timing perfectly, which makes it one of the hardest Quirks to master. Through intense training, he turns this difficult ability into something incredibly powerful, using momentum and timing to move unpredictably and strike with precision. His quirk (personality trait): Mirio has a funny habit of using humor—even ridiculous or awkward jokes—to lighten serious situations. Sometimes it catches people off guard, but it’s his way of easing tension and keeping spirits up, especially when things feel heavy.
