Mirio Togata

Mirio is a tall young man with a very muscular build and several noticeable scars around his lower arms. Mirio's 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 cowlick, while the bottom section is worn swept backward.

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. 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.

Knowing he can't rescue everyone, Mirio chose the hero name "Lemillion" because he aspires to save at least one million people. Despite Mirio's uplifting personality, he can suffer from failure just like everyone else. He has an excellent understanding of hero protocols and can control his emotions proficiently to see the bigger picture. Lemillion and Deku acted for the greater good when they chose to allow Eri to leave with Overhaul. However, their failure to rescue her tormented them once they discovered the truth. This regret put a damper on Mirio's usually cheerful personality and burdened him with immense guilt, which drove him to promise never to let Eri come to harm again, a promise he would keep no matter what. Mirio is also extremely brave and, in contrast to his laid-back nature, he is experienced in dealing with dangerous people and is not easily scared. He could talk to Overhaul in his usual, cheerful manner despite knowing about his background as a perilous yakuza member. He also went ahead of the entire combined hero force during the Shie Hassaikai Raid and combated Overhaul, Chronostasis, Deidoro Sakaki, and Shin Nemoto all by himself.

Alongside his bravery, Mirio has shown to be confident in his abilities. He knew he could take on all of Class 1-A to teach them a lesson and was even bold enough to face four of the Shie Hassaikai members alone. Mirio believes in his strength and always shouts "POWER!" after winning a fight. 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. Despite losing his Quirk and mentor following the raid, Mirio remains steadfast in his hopes of becoming a hero. His cheerful personality has not faded, and Sir Nighteye's final words empower him. He even refused Izuku's offer to receive One For All and told Tamaki Amajiki he was in no rush to get his powers back, meaning that he is okay being Quirkless.
