Age: 18 Birthday: July 15 Gender: Male Height: 181cm (5'11¼") Hair Color: Blond Eye Color: Blue Blood Type: O Quirk: Permeation Affiliation: U.A. High School, The Big 3, Nighteye Agency Birthplace: Chiba Prefecture Fighting Style: Close combat Mirio is a tall young man with a very muscular build and several noticeable scars around his lower arms. His design is unique due to his beady blue eyes, drawn in a simplistic style with no visible sclera, and nose prominently rounder than most others. He has blond hair, the top part of which is arranged in a quiff hairstyle, while the bottom section is worn swept backward. In his school uniform, Mirio dresses like most of the male students, though he wears a belt with a large, rectangular golden buckle shaped like a carnivorous mouth. Mirio usually comes across as a highly goofy and energetic individual with peculiar habits. Based solely on his personality, many question how Mirio is one of U.A.'s top students. Mirio has a very optimistic attitude and can almost always be found smiling. His character is what led Sir Nighteye to believe that he could be the one to replace All Might as the symbol of peace. Mirio is known for his odd sense of humor. His jokes range from corny to puerile, occasionally making a fool of himself for others' enjoyment. One such instance was when he stuck his clothed butt through the bushes as a puppet when introducing Class 1-A to Eri. Mirio does not allow his laid-back nature to cloud his judgment or impede his dreams of becoming a hero. He has proven an extremely hard worker, turning a near-unmasterable ability into one of the world's most powerful Quirks. Mirio is constantly looking for ways to improve his skills and tries to work toward his goals by accumulating different experiences to learn from them. Lemillion repeatedly displays the values of a true hero. He risked his life and even sacrificed his Quirk to protect Eri. Despite knowing how it would negatively affect his career, Mirio allowed his Quirk to be destroyed to inspire Eri and keep his promise never to let her know pain again. Mirio's bravery allowed Eri to awaken and set the path for the heroes to defeat the Yakuza. Lemillion even continued fighting after losing his Quirk and protected Eri from Overhaul. His incredible tenacity caused Shin Nemoto to question whether he was even human. Permeation: Mirio's Quirk allows him to become intangible, letting him pass through any tangible matter; he can phase through walls or the ground, as well as let enemy attacks pass through him harmlessly. While intangible, he experiences a falling sensation because he still has mass. Furthermore, everything passes through him, including light, sound, and air, meaning he can't see, hear, or breathe while his Quirk is active. This aspect of his ability also means that he has to keep at least one foot solid at all times while his Quirk is active, or else he will fall into the ground.[8] According to the laws of physics, things with mass cannot overlap; if Mirio returns to his solid state while phasing through something, his body will be repelled outward. By adjusting the direction he is facing or the pose he is holding, he can control the direction from which he is repelled.

Gender: Male Height: 176cm (5'9") Age: 17 Shoto is a moderately tall, muscular teen shaped by harsh childhood training. His short hair is split evenly—white on the right, crimson on the left—matching his heterochromia: turquoise left eye and dark gray right. A burn scar runs down the left side of his face. He’s usually serious, though classmates consider him handsome, with Mina calling him the best-looking boy in 1‑A. At U.A., he wears the standard uniform but swaps dress shoes for pale cyan‑gray sneakers. Once cold and aloof due to his upbringing, he kept to himself and showed little emotion. After the Sports Festival, he became kinder, more sociable, and occasionally humorous, though still somewhat distant and dense with social cues. Calm yet brutal in combat, he often acts alone to avoid limiting his power. His Quirk, Half‑Cold Half‑Hot, lets him generate ice from his right side and fire from his left. Favoring ice for years made controlling flames harder, and overusing one side risks frostbite or heatstroke.

Gender: Female Height: 173cm (5'8") Age: 16 Momo is a tall, elegant young woman with a lean, athletic build shaped by disciplined training. Her long black hair is usually tied in a high, spiky ponytail that highlights her sharp features and calm, intelligent eyes. She carries herself with refined confidence and is often noted as one of Class 1‑A’s most striking students. Her uniform is always neat, and her hero costume prioritizes mobility for her Creation Quirk. Raised in a wealthy but supportive household, Momo developed a polite, earnest, and studious personality. Analytical and level‑headed, she often takes leadership roles thanks to her strategic thinking. Despite her natural talent, she once struggled with self‑doubt but grew more assertive after key battles. Kind and respectful, she’s eager to help classmates, though sometimes overly formal. In combat, she stays composed and resourceful, creating weapons and tools on the fly. Her Quirk lets her produce any nonliving material using lipids and precise knowledge.
