For loyal viewers of the My Hero Academia anime, the name Mirio Togata is undoubtedly familiar. Known by his hero alias, Lemillion, he boasts a highly unique and compelling character. He is not only a formidable fighter but also possesses a natural talent for bringing joy to those around him.
Furthermore, from Qiuqa’s perspective, Mirio’s face bears a striking resemblance to the legendary comic book character Tintin. Both share a cute, charming facial structure that makes them distinct and instantly recognizable.
Naturally, there are many more fascinating details about Mirio Togata worth exploring. Here is a breakdown of 10 interesting facts about Lemillion that you should know!
1. Mirio Togata’s Profile
His full name is Mirio Togata, and he chose the hero name “Lemillion.” He picked this alias to reflect his ultimate dream: to save a million people.
Mirio possesses a Quirk called Permeation, which allows his body to phase through anything when activated. Even air and his own breath pass directly through him, making him seemingly “vanish” from the physical world for brief moments.
• Date of Birth: July 15
• Height: 181 cm
• Blood Type: AB
• Likes: Ramen and Comedy
2. He is a Member of U.A. High’s “Big Three”
U.A. High School is an elite, premier institution for hero education. The Symbol of Peace and former number one hero, All Might, is an alumnus. The graduation rate is incredibly low, and the selection process is ruthlessly strict. Given the school’s prestige, it naturally hosts a multitude of gifted students.
However, standing at the absolute apex of U.A.’s hero course are the “Big Three.” These three students hold the highest rank among their peers and are widely considered the closest to reaching the level of pro heroes. They are Mirio Togata, Tamaki Amajiki, and Nejire Hado. According to Mr. Aizawa, Mirio is the single person closest to claiming the number one spot among all pro heroes.
3. The Mechanics of His Permeation Quirk
Many assume Mirio possesses two distinct powers: permeation and teleportation. In reality, he only has one Quirk. His “teleportation” is simply a strategic application of Permeation. For instance, when Lemillion phases into the ground and deactivates his Quirk, the physical mass of the earth forces his body to violently repel back to the surface. This rapid ejection creates the illusion of teleportation. By calculating the angle and position of his body, Lemillion can aim his launch and pinpoint his exact destination.
Lemillion once sparred against the entirety of U.A.’s Class 1-A (excluding Bakugo and Todoroki). During this bout, he activated his Quirk and shed all his clothes, leaving the students stunned and deeply embarrassed. He chose to fight nude to ensure he could phase through objects without the restriction of normal fabric. After the match, he promptly apologized to the female students for the stunt. Even while fighting naked, he constantly shifted into deliberate poses to obscure his vital areas.
Unsurprisingly, during the hero raid on the Shie Hassaikai stronghold, Kirishima—a Class 1-A student who had witnessed Lemillion’s nude tactics—worried when Lemillion prepared to phase through a wall. He assumed Lemillion was about to fight naked in front of several pro heroes.
Interestingly, when wearing his official hero costume, Lemillion can phase through anything without stripping. This is because his suit is woven from special fibers derived from his own hair, allowing the fabric to phase alongside his body when his Quirk is active.
4. His Deep Regret Over Not Saving Eri
This tragic realization began while Lemillion and Deku were on a covert street patrol, investigating the Shie Hassaikai yakuza group. Suddenly, a terrified young girl named Eri sprinted out and collided with Deku. To their shock, the person chasing her was Chisaki, the ruthless leader of the syndicate. Both heroes immediately recalled Sir Nighteye’s strict orders: do not arouse the group’s suspicion during patrol.
Lemillion attempted to play it cool, chatting casually with Chisaki before signaling Deku to move on. However, Eri clung tightly to Deku, trembling and sobbing in terror, begging him not to leave. While Lemillion chose not to intervene to preserve Nighteye’s plan, Deku was entirely focused on Eri’s distress. Noting the suspicious bandages wrapped around her limbs, Deku firmly intended to take her away.
Chisaki then claimed Eri was his daughter—a lie meant to deceive them—and warned them not to interfere in family matters. Removing his glove in a silent threat, Chisaki sent Eri into a panic. Terrified, she released her grip on Deku and surrendered, following Chisaki into the shadows while the two heroes watched helplessly.
Later, during a hero conference led by Nighteye, Fat Gum delivered critical intelligence: the syndicate possessed weapons capable of erasing Quirks. Analysis revealed that these bullets were manufactured using human blood and cells. Nighteye grimly concluded that the source was likely Eri’s blood, a theory supported by Deku and Lemillion’s observation of her heavily bandaged arms.
The realization that Chisaki was harvesting Eri’s blood to create Quirk-destroying bullets struck Deku and Lemillion with devastating force. Their guilt deepened when the hero Rock Lock pointedly noted that the threat could have been thwarted had they simply rescued Eri then and there. A profound sense of remorse engulfed both heroes, especially Lemillion, who lost his trademark cheerful demeanor, haunted by the crushing weight of his inaction.
5. His Mentorship Under Sir Nighteye
Sir Nighteye, All Might’s former sidekick, broke convention by directly requesting Mirio to join his hero agency, rather than waiting for the student to seek a work-study placement. Nighteye grew incredibly fond of Mirio, treating him with such warmth that Bubble Girl—who had worked alongside Nighteye for years—admitted she was jealous. Mirio himself noted a stark contrast; while Deku often faced grueling treatment, Nighteye frequently smiled and joked around when training Mirio.
Nighteye taught Mirio to keenly observe his enemies and predict their every move in combat. He pushed Mirio to simulate a vast array of scenarios, transforming those trials into invaluable experience. Thanks to this rigorous mentorship, Mirio successfully countered Chrono and Chisaki’s deadly assaults during the stronghold raid. His close friend, Tamaki Amajiki, noted that Mirio’s relentless work ethic under the guidance of pro heroes—especially Nighteye—was what honed him into the powerhouse he became.
Tragedy struck when Nighteye was left in critical condition following his battle with Chisaki. Despite his own severe injuries, Mirio forced himself into Nighteye’s hospital room. Weeping, he pleaded with his mentor to survive, confessing that it was Nighteye’s teachings that made him strong and that he still had so much to learn.
Fate, however, was unforgiving. Sir Nighteye passed away, plunging Mirio into deep grief. But before taking his final breath, Nighteye used his Quirk to look into Mirio’s future. With his dying words, he assured a heartbroken Mirio that he would be fine, and that he was destined to become an outstanding hero.
6. He Was the Top Candidate to Inherit One For All
The catalyst for this succession crisis was All Might’s devastating battle against All For One. Though victorious, All Might suffered catastrophic injuries—half his respiratory system was destroyed, his stomach was decimated, and he endured multiple surgeries. Consequently, his physique withered, capping his hero work at a mere three hours a day. Deeply concerned, Nighteye urged All Might to retire while he was still revered as a legend.
Principal Nezu, Gran Torino, Recovery Girl, and Nighteye—the few who knew the secret of One For All—collectively agreed that All Might needed to swiftly designate a successor. Principal Nezu formally recommended U.A.’s Mirio Togata. Nezu argued that while Mirio’s academic grades were unremarkable, his sheer charisma was unparalleled.
Mirio had a magnetic ability to bring joy to everyone around him; his bright smile never faltered. To Nezu, Mirio was the living embodiment of All Might’s ideal hero. In fact, Nighteye’s primary motivation for training Mirio was his unwavering belief that the boy was the perfect vessel for One For All. Through Mirio’s loyalty and dedication, he unknowingly became Nighteye’s greatest pride.
However, destiny intervened. Before All Might could officially meet Mirio, he crossed paths with Izuku Midoriya. All Might later realized that had he not met Midoriya, Mirio Togata would have undoubtedly inherited One For All.
7. His Overwhelming Combat Strength
Mirio Togata’s strength is staggering. He single-handedly decimated nearly the entirety of U.A.’s Class 1-A (save for Bakugo and Todoroki). Despite Class 1-A dividing themselves into coordinated long-range and close-quarters combat teams, Mirio dismantled both squadrons with effortless precision.
Later, while frantically pursuing Chisaki to rescue Eri, Lemillion was forced into a two-on-one battle against Shin Nemoto, a lethal marksman, and Deidoro Sakaki, whose Quirk induced crippling vertigo. As Nemoto fired his gun and Sakaki threw knives simultaneously, Lemillion adapted in a fraction of a second. He phased into the wall, used the violent physical repulsion to slingshot himself forward, and struck both enemies in rapid succession, neutralizing them in a single fluid motion.
Even Chisaki, the terrifying leader of the Shie Hassaikai, was completely outclassed by Lemillion. Chisaki was battered mercilessly, unable to mount any meaningful defense, and was forced to admit that Lemillion was fundamentally stronger. Even after permanently losing his Quirk mid-battle, Lemillion continued to fiercely pummel Chisaki, holding the upper hand through sheer physical prowess.
8. Sacrificing His Quirk to Protect Eri
Lemillion viewed Eri as a profoundly kind girl, knowing she had willingly returned to Chisaki’s hellish torture just to spare him and Deku during their patrol. The thought haunted him; he felt pathetic and cruel for failing to protect a little girl. Driven by this guilt, Lemillion entered the raid with an ironclad resolve: he would save Eri, no matter the cost.
After tearing through numerous obstacles, Lemillion finally ripped Eri from Chisaki’s grasp. Highly vigilant, he kept a close watch on Chrono, Chisaki’s assistant, determined not to fall victim to a Quirk-erasing bullet. When Chrono fired at them, Lemillion brilliantly countered by sweeping his hero cape over himself and Eri to obscure Chrono’s aim, before delivering a devastating kick that knocked the villain unconscious.
Lemillion then unleashed his fury on Chisaki. However, caught in the momentum of the beatdown, he failed to realize that Nemoto had regained consciousness. Desperate, Chisaki tossed the final Quirk-erasing bullet to his subordinate. Knowing he only had one shot and that Lemillion could easily phase through a direct attack, Nemoto resorted to a vile tactic: he aimed the gun point-blank at Eri.
Exactly as Nemoto predicted, Lemillion didn’t hesitate. He threw himself in the path of the gunfire, shielding Eri with his own body. The bullet struck true, and Lemillion’s Quirk vanished—sacrificed to ensure a little girl’s safety.
(Fans, however, could eventually breathe a sigh of relief. As revealed later in the manga, Lemillion’s Quirk is successfully restored thanks to Eri’s “Rewind” ability.)
9. The Lifelong Struggle to Master His Quirk
When Mirio was a boy, his father warned him that the Permeation Quirk was incredibly dangerous to wield. A single miscalculation could literally split his body in two. This lethal risk had forced his father, who possessed a similar Quirk, to abandon his own dreams of hero work. Yet, young Mirio was fiercely determined to become a hero and fully prepared to endure the grueling training required. Moved by his son’s resolve, his father promised to support him wholeheartedly.
Even after enrolling at U.A. High, Mirio’s control was far from perfect. During a demonstration where he was tasked with phasing through a wooden wall, he misjudged the activation. While his hands successfully phased through the barrier, his face and torso slammed violently into the solid wood.
His classmates erupted into laughter at the blunder. Unfazed, Mirio maintained his composure, calmly explaining to them that mastering his Quirk was exponentially harder than it looked—at least five times more difficult than any of them could imagine.
10. His Relentless Love for Comedy
Mirio Togata is defined by his boundless, radiant energy and his relentless love for a good joke. For instance, when Mr. Aizawa brought him in to explain the hero work-study program to Class 1-A, Mirio ignored any formal presentation. Instead, he yelled out, “The future is gonna be…!” expecting the class to finish the phrase. He was met with absolute, deadpan silence from the bewildered freshmen.
On another occasion, while Class 1-A was preparing for the U.A. School Festival, Mirio brought Eri by to watch. Attempting a comedic entrance from the bushes to surprise Midoriya and the others, his plan was foiled when Midoriya instantly spotted and greeted him.
Refusing to break character, Mirio stayed in the bushes, stuck his rear end out, and wiggled it, loudly declaring it was a “fresh peach.” Tragically, his physical comedy was completely ignored, as the students’ attention had instantly gravitated toward Eri.
In short, Mirio is a guy who never stops trying to land a punchline, even when the room is tough. Ultimately, when no one else laughs at his antics, he is perfectly content to laugh at himself.
