"I turned my work-study experience into power that's allowing me to reach for the stars! Which is why, even if you're scared, I wholeheartedly recommend it to you, first-years!!"

Mirio Togata to Class 1-A in "The Quickening! The Internship Episode!"

Mirio Togata ( (とお) (がた) ミリオ Tōgata Mirio?), also known by his hero name Lemillion, is a third-year student at U.A. High School and is part of The Big 3. Before Izuku Midoriya, Mirio was the top candidate for All Might's successor and inheritor of One For All.


Mirio Color Scheme

Mirio's color scheme.

Mirio is a muscular young man with scars on his arms. His face is drawn in a simplistic, cartoony way and his blond hair is arranged in a cowlick.

His hero costume consists of a large mask which covers the space around his eyes and ears, a plated shirt with the number one million (1000000) across his chest, with black pants and boots with green trimmings. He also sports a floor-length orange cape attached from the chest which features a hood. Additionally, Mirio's hero costume (except for his mask) is made of a special fiber that is derived from his hair, which allows the costume to become intangible alongside him.

In his childhood, Mirio had kept his hair in a short ponytail.


Mirio comes across as goofy and energetic, with some peculiar habits. He is almost always smiling and, though optimistic, he does not let his ideals blind him, and is always looking for ways to improve his skills. He is very devoted to becoming a hero and is the top candidate for No.1 Hero after he graduates, even surpassing many of the pros. Despite his lacking academical performance, he is extremely dedicated and has worked many hours to perfect the use of his Quirk for combat, and thus is ranked among the top 3 students at U.A. His hero name, "Lemillion", comes from his desire to rescue a million people, inspired by All-Might's debut.

As an intern, Mirio has developed a good understanding of the protocols and actions that a Hero must be able to do in various situations. He is able to separate himself from his emotions in order to see the bigger picture. He understands when he has to go against what he feels is right in order to act for the greater good.

In contrast to his laidback nature, he is experienced in dealing with dangerous people and does not scare easily, as shown when he was able to cheerfully speak to Overhaul, despite knowing exactly who he was, maintaining a cover of ignorance. He is able to remain calm when he has to, even casually informing Izuku to pull his mask on to conceal his identity. In spite of all of this, he is not totally able to disconnect himself from the realities of being a Hero. When it was revealed that Eri was being used as part of Overhaul's plans, he was visibly mortified at the fact that he and Izuku had been so close to rescuing her from such a fate. He then became extremely determined to rescue her. As of his fight with Overhaul and his minions, it is shown that Mirio is very self-aware, as he realized how he endangered Eri when he first saw her in order protect his cover and the success of his mission. While this left him feeling immense guilt, he accepted it as a necessary risk caused by his career and did not let it affect him.

Since the full use his Quirk often leaves him nude, he has gotten somewhat used to it and isn't afraid to fight without clothes; though he will apologize, especially to girls, for the rudeness.

Even after the loss of both his quirk and mentor, Mirio was still resolved to be a hero and he was not dismayed as Sir Nighteye's last words gave him hope. Like All Might, Mirio smiled in the face of adversity and held faith that his problems will be resolved.

When he was told of his quirk possibly returning, Mirio simply laughed and stated he was in no rush to regain his power.[2]


During third grade, a new transfer student was not able to give a proper self-introduction, and because of his social awkwardness, he was not able to make any friends. Mirio approached this student, Tamaki Amajiki after realizing that Tamaki was trying to say that he likes Heroes; it was this recognition that began the friendship between Tamaki and Mirio. In middle school during a Quirk Education class, Tamaki tried manifesting something but only managed to manifest a tiny plant on his hand due to his nervousness. Meanwhile, Mirio tried phasing through a wall but only managed to phase his hands through it. Some of Mirio's classmates laughed at his struggles, but he was not disheartened at all and resolved to pull off his phasing properly next time. While walking home, Tamaki praised Mirio's optimism while lamenting on his own lack of self-esteem. Mirio cheered up Tamaki and said that he will shine brightly like the sun and the reason he can give it his all is due to Tamaki being there for him. Although he was nervous, Mirio praised Tamaki's resolve never to give up which inspired him never to give up either. Despite Tamaki thinking of himself as a boring person with low self-esteem, Mirio always thought of Tamaki as a talented person who is cool and super fun and sunny to be around with. [3]

After middle school, Mirio and Tamaki entered U.A. According to Nejire Hado, Mirio once struggled a lot at U.A. High School (even showcasing poor results in an edition of the Sports Festival); however, he would turn around his situation by devoting himself as an intern under the hero Sir Nighteye and having his abilities cultivated during his internship, eventually becoming a major contender for the number one rank, above several pro heroes.


Internship Arc

Mirio Meets Izuku for the first time

Mirio meets Izuku

Mirio appears before Izuku Midoriya inside a wall and floor, encouraging him to keep his spirits up. Three days later along side his fellow Big 3 members, they are introduced to Class 1-A.[4]

Upon introducing themselves, he mentions internships about Class 1-A and challenges them to a fight. Inside Gym Gamma after Class 1-A attacks first, he defeats the long-range quirk users with a single strike.[5]

Now targetting close-ranged quirk users he runs towards them and phases through the ground. Appearing behind them and defeats the students one after another. When the fight finishes, Mirio questions if they found his quirk strong and then reveals its functions. Explaining how his internship helped with his quirk, he says it's an opportunity they can't afford to miss out on. After leaving the gym, Tamaki Amajiki asks him if anyone caught his eye. Mirio mentions Izuku Midoriya's performance.[6]

Later on, stood alongside Izuku they visit the restroom where All Might invites them to come in. [7]

Sat inside the restroom next to Izuku Midoriya, All Might asks his on opinion on Izuku working under Sir Nighteye. All Might mentions he would be unable to face Sir Nighteye himself. Mirio asks Izuku what kind of hero he wants to be. When Izuku reveals his goal of wanting to be the greatest hero, he claims he has no reason to refuse introducing Izuku to Sir Nighteye.. Later that day he takes Izuku to the area of Sir Nighteye's offices and explains he has very strict standards. Proceeding to guide him to Sir Nighteye's office, he offers him pieces of advice along the way.[8]

Freeing Bubble Girl from a shackled wall, she asks what's Izuku to him, Mirio mentions that he's an underclassman he's taking care of. Observing Izuku, he notes although he wasn't able to make Sir Nighteye laugh, he can't argue with the result and that's got his foot through the door. When Sir Nighteye challenges Izuku to test and asks Mirio and Bubble Girl, she asks him if he had to undertake something similar. He reveals Sir Nighteye personally chose him and he didn't. As Bubble Girl reveals her jealousy, Mirio begins to think about Izuku's test against Sir Nighteye. [9]

When they both re-enter Nighteye's office Mirio asks if it's over as it got pretty loud. Nighteye tells Mirio, Izuku is hired. The next day stood outside with Sir Nighteye, Bubblegirl, and Izuku, they inform Izuku of their secret investigation. Both Mirio and Izuku begin to patrol the area until they encounter into a girl with Kai Chisaki behind her.[10]

Upon encountering Chisaki, Mirio throws Izuku his mask and says they should be the ones to say sorry. Chisaki mentions it is the first time he's seen them, and asks if they are new, after which Mirio tells him that they are. When Chisaki asks what office they're with, Mirio tells them they're students being allowed to patrol for experience, secretly knowing he can't reveal about Sir Nighteye. As Mirio asks for them to go, Izuku begins to start questioning Chisaki about the girl. As they follow Chisaki into an alley for further questioning, the girl returns to his side and they bid farewell to the heroes. Izuku goes to follow them but Mirio stops him following. Questioning if he noticed the killing aura, he says to respect Sir Nighteye's orders.[11]

Meeting up with Sir Nighteye, he apologizes for having an incident. Sir Nighteye says it was an error on his part, and if he'd seen it he could have prevented it. Afterward, Mirio tells Nighteye of Chisaki's daughter. Izuku mentions wanting to save her. Sir Nighteye tells them both the cleverest villains hide the shadows and now is a good time for them to learn. [12]

A few days later, Mirio attends the meeting regarding Shie Hassaikai in Sir Nighteye's offices.[13]

Throughout the meeting when Izuku and Gran Torino begin talking, Mirio questions about them knowing each other. When Fatgum mentions Tamaki Amajiki was shot by a bullet that can destroy quirks. A concerned Mirio asks if he is okay. When Sir Nighteye mentions Chisaki's quirk along with bullets that can destroy quirks, Mirio becomes terrified. When they come to the conclusion that Eri's body is being used to create bullets, both Izuku and Mirio vow to protect her.[14]

When the meeting ends Mirio returns to U.A. High School sat at a table surrounded by fellow students. With his head down, Tamaki asks him to lift his head. When Nejire Hado tells Mirio if he's feeling down or regret. She asks if he knows he can do about it. Mirio agrees.[15]

Days later, late at night. The Big 3 gather after receiving a message containing information on the day carry out the plan to raid Shie Hassaikai. Hours later, when everyone is gathered together. Mirio becomes fired up. Sometime later, after changing into his hero costume alongside everyone else they gather outside the home of Shie Hassaikai. [16]

Inside the house upon reaching the underground. Believing to have found themselves at a dead end. Mirio prepares to go ahead to look and phases through the room. Seeing a corridor like Sir Nighteye foresaw. Mirio returns and tells him a wall is blocking their way. After Izuku and Kirishima knock down the wall the floor starts to warp. When Tamaki says if the pathway keeps changing they'll never reach their goal. Mirio tells him that's never gonna happen, not to mention it's all a stopgap measure. He reveals no matter if the passage is warped as long as he knows the right direction he can get there and phases into the floor. [17]

Mimic causes the floor to open up beneath the Heroes, causing the heroes to fall down a single floor. The heroes are in a hall; three figures appear from the dust, revealing themselves to be three members of the Eight Expendables.

Mirio appears before Chisaki and attacks simultaneously. Mirio strikes Chisaki with a backhanded smack, to which Chisaki avoids, but he still managed to leave a mark on Chisaki's face while kicking Chronostasis. Mirio avoids hitting Eri thanks to his Permeation and strikes Chronostasis down with his kick. Chronostasis falls back as Mirio grabs hold of Eri. Eri tells Mirio to run away otherwise Chisaki will kill him. However, Mirio promises to never let Eri be sad again and tells her that everything is fine because he is her Hero.[18][19]

Mirio attacks Chisaki and Chrono

Mirio attacks the villains

Mirio has recovered Eri from Kai Chisaki. Chisaki begins wiping off the mark Mirio left on his face as he threatens Eri to return to him because she was born to destroy people, otherwise Mirio will be murdered. Before Eri can speak, Mirio tells her to not listen to Chisaki's words. When Chisaki mocks Eri for her existence being a curse, much to Mirio's chagrin who wonders why Chisaki is saying such harsh words to his own daughter. However, as he takes off his glove, Chisaki reveals that Eri is not his daughter. Chisaki places his hand on the ground and deconstructs it using his Quirk. [20]

Chisaki reconstructs the crumbled ground into massive spikes that attack Mirio, but Mirio quickly phases his body while holding up Eri with his arms, protecting both of them. Mirio is surprised at Chisaki's quick speed as well as his lack of regard for Eri while Chisaki himself praises Mirio for being more than just his Quirk. Chisaki launches more spikes at Mirio, uncaring at Eri's safety since he can just "repair" her easily and reveals to Mirio that Eri has experienced it firsthand; Chisaki's words enrage Mirio. Mirio continues avoiding the spikes while Chisaki asks Mirio about Eri's safety in his hands since if she gets hurt she cannot be healed immediately and that having her is making it troublesome for him as he cannot run away using his Permeation while carrying Eri. Due to him reconstructing the area with spikes, Chisaki has managed to cut off Mirio's escape route. Chronostasis has awakened and has a gun in his hand that is loaded with Quirk-disabling bullets. Mirio is surprised that Chronostasis is still awake after being hit by him and assumes that Deidoro Sakaki's Quirk made his physical attacks weaker at the time. Chisaki orders Chronostasis to aim at Mirio's arms while he destroys the spikes so that Mirio loses his ground. Chisaki deconstructs the ground, causing Mirio to be in mid-air. Mirio conceals himself and Eri using his cape; Chronostasis fires at Mirio but misses due to his target being concealed by the cape.

Mirio tries to appear before Chronostasis but Chisaki anticipated this strategy and begins reconstructing the ground beneath his second in command. Mirio does indeed appear before Chronostasis, using his Quirk's instant transportation to do so. Mirio's shoulder knocks Chronostasis's arm which causes him to drop the gun and is about to hit Chronostasis with a punch, but Chisaki launches Chronostasis away from Mirio by reconstructing a platform which saves Chronostasis, who apologizes to Chisaki. Seeing that Mirio is stronger than he thought, Chisaki decides to break Mirio's morale by killing Eri. Before he can do so, Mirio uses his instant transportation to appear behind Chisaki. Chisaki realizes this and tries blocking Mirio with his hand, but Mirio phases his arm through Chisaki and punches him in the face.

Chisaki lands on the ground as Mirio states that his cape is for bundling up Eri who is in terrible pain. Chronostasis gets up and tries getting the gun, only for Mirio to appear before him and knock him back down. Mirio praises Chisaki for his abilities being far above that of the average yakuza but tells him that he is far stronger, using his instant teleportation to appear before Chisaki and lands another punch against him. Eri watches the fight and is surprised at not only Mirio's strength but the lengths he is willing to go for her. Mirio swears to never let Chisaki lay another finger on Eri and promises to take them both down, declaring that he has them in checkmate.

Chisaki becomes enraged at Mirio calling out his name since he abandoned it long ago. Years ago during Chisaki's childhood, the boss of the Eight Precepts of Death took Chisaki in since he had nowhere he could call home and asked for Chisaki's name, to which he states that his full name is Kai Chisaki. Several years later, the boss of the Eight Precepts of Death lamented about the destruction of a yakuza group; Chisaki told the boss about the plan he had discussed with him before, but the boss did not take heed of it because falling off from the part of humanity would cause his demise as a gangster since people would not follow brutes with no hearts.

Mirio still stands

Resolved to protect her Mirio stands in the way to save Eri

Mirio immediately jumps towards Eri. Mirio was able to tell that Eri was endangered because she wouldn't scream or cry whenever murderous intent was directed at her and she would simply close her eyes, be silent and grit her teeth; this was Eri's habit that was engraved in her after living in pain and fear for a long time.

Mirio reaches Eri while Shin fires the Quirk destroying bullet. Eri opens her eyes and sees a smiling Mirio who is about to be hit by the Quirk destroying bullet. Mirio thinks about his childhood where his family's Quirk made it difficult for them to become Heroes, which is why his father gave up on becoming a Hero. However, Mirio refused to waver and throughout his life, he worked extremely hard to hone his Permeation; eventually, Sir Nighteye saw potential within Mirio and made him his sidekick. Under Sir Nighteye's guidance, Mirio was able to turn his Permeation into a full combat Quirk; during this time Mirio along with Tamaki and Nejire began being acknowledged as the Big Three.

Mirio covers Eri as the Quirk destroying bullet is shot into his body which begins destroying Mirio's Permeation. Chisaki states that due to Quirks people are entitled to dream and begin thinking that they become people that matter, to which Chisaki believes that these people are sick in the head. As Shin celebrates his triumph, Chisaki laughs at Mirio's efforts and mocks Mirio for smiling because everything he has worked so hard to cultivate has been reduced to naught. As Chisaki is about to deconstruct the ground, Chronostasis is thrown at him, courtesy of Mirio's kick. Mirio appears before Chisaki and punches his arm. Mirio tells Chisaki that all his hard work isn't in vain because he will still be Lemillion. Chisaki tries attacking Mirio but Mirio, while quirkless, fights him back for five minutes all in order to protect Eri from Chisaki.

When Nighteye begins to succumb to his wounds, Mirio ran into his room and begged his mentor not to leave as he still had much to learn from him. Nighteye comforted Mirio by using his Quirk one final time to tell him he'd be a great hero in the future.[21]

Much later, Izuku visits Mirio who is doing exercises on his bed, surprisingly in a cheerful mood despite all that has happened. Mirio is glad that he is in top shape and he knows that he has lost his Quirk along with Sir Nighteye and has no right to be cheerful. However, Mirio has decided not to be sad because Sir Nighteye was smiling all the time while talking to him and will respect his teachings by also smiling since he is going to be an outstanding Hero in the future and having a glum face will make Eri sad.

When Izuku hypothetically asks Mirio if he could give Mirio his Quirk, would Mirio accept it. Surprisingly, Mirio replies that he would refuse Izuku's offer, telling Izuku that by accepting his Quirk, Izuku would suffer hardship. Although he does not understand why Izuku feels dejected, Mirio thanks Izuku for doing a great job. Mirio feels positive about the situation because when he spoke with Aizawa about when Eri gets control of her Quirk in the future, she will be able to restore him to a state where he had his Quirk. Mirio asks Izuku to smile; Mirio's optimism convinces Izuku to accept the reality. Izuku tells Mirio that he will be waiting for him to return to U.A. while he is taking a temporary leave of absence.[22]

U.A. Cultural Festival Arc

Visiting Eri in hospital, alongside Izuku Midoriya. While Izuku apologizes to Eri for being unable to see her earlier Mirio gifts her a fruit basket. Eri apologizes to them for all the trouble for her sake. When Eri starts feeling guilty for Mirio losing his Quirk, Mirio tells Eri that she is not to blame and everyone is glad that she is safe. Suddenly, Izuku has an idea and asks Shota Aizawa if Eri can come to the Culture Festival. Mirio explains to Eri that the festival is an occasion that U.A. High School hosts lots of events on display where people can enjoy themselves while tasting delicious food.[23]

Eri freed from chisaki

Mirio watches Eri smile at the festival.

At the Festival, Mirio takes Eri to the show which Class 1A has set up and he holds her up so she could see it. When Eri sees Izuku performs, a happy Mirio watches with tears in his eyes as the child laughs for the first time. [24]

Later on, Mirio and Aizawa inform Izuku and Class 1A that Eri will be taken in by the school. Mirio explained the growth of her horn and states they need to monitor her so it doesn't get out of control. Tamaki Amajiki pats him on the shoulder and mentions if Eri's abilities become stable and she gains control, Mirio's quirk could possibly return to him. Mirio laughs at the idea by stating it would be neat as he smiled at his friend. [25]

Quirk and Abilities

Permeation: Mirio's Quirk allowed him to become intangible, letting him travel through solid walls and the ground,[26] while letting enemy attacks slip through him. However, when he becomes intangible his clothes slip through him, leaving him nude. By activating his Quirk, he can slip through the floor into the ground, then reposition himself and deactivate to cause himself to shoot back out of the ground in a different spot. However while fully intangible, he can no longer see, hear, or breathe, and can only experience a falling sensation.[27] He can also remain intangible while physically permissible enough to launch counter-attacks.[28] Mirio lost his quirk after the fight when he was repeatedly struck by bullets containing the Quirk-Destroying Drug.

  • Blinder Touch: Eyeball Crush: A faint, Mirio pretends to poke an opponent in the eye while his arm is intangible, distracting them long enough to deliver an actual blow to their stomach.
  • Killing Move Phantom Menace: A near instantaneous combo, Mirio consecutively launches himself at high speeds in and out of his surroundings with all of his brute strength, striking all targets precisely with pin-point accuracy and calculation from all directions.
Togata Power

Mirio showcasing his strength against Class 1-A.

Overall Abilities: Mirio is extremely powerful, showcasing incredible mastery over his Quirk, such that the students of Class-A thought him to be invincible. He is considered the top contender for the rank of number one hero, previously held by All Might and currently occupied by Endeavor. He was able to beat half of Class 1-A in less than six seconds.[27]

Mirio was able to defeat two of the Eight Expendables with relative ease despite being inhibited by their Quirk abilities, whereas it took Tamaki and all his strength to defeat three of the Eight Expendables, showing that Mirio is above his peers of the Big Three. Mirio was able to overpower Chisaki, the leader of the Eight Precepts, a powerful Yakuza to the point that Chisaki himself admitted that Mirio was stronger than him and was forced to resort in destroying his Quirk to even the playing field.

Even after losing his Quirk, Mirio was still able to hold his own against Chisaki and remain conscious despite being on the receiving end of Chisaki's reconstructed attacks.

Enhanced Strength: Mirio seems to possess a good deal of physical strength, enough to knock out a person and crush floors easily. This appears to come from his well-trained muscular body.

Enhanced Speed: Mirio is also incredibly fast, taking out Class-A very quickly and with absolute ease. This, combined with his strength and the rapid relocation aspect of his Quirk makes him incredibly formidable in combat. Mirio was fast enough to land a scratch on Chisaki's face who is known for his fast reaction time.

Enhanced Durability: Even without his Quirk's intangibility, Mirio has great durability, enough to survive Chisaki's reconstructed attacks and remain conscious despite being heavily injured.


Specialized Costume: Since Mirio's Quirk usually lets him phase out of his clothes and leave him nude, he has a Costume that is made of a special fiber that is produced from his hair. That way, his clothes will react when his Quirk activates and also become intangible.[29]



Tamaki Amajiki

Mirio, Tamaki, and Nejire have known one another over the three years of their studies at U.A. During their years of study, Tamaki and Nejire have seen the endeavors Mirio had to go through and understood what he went through to become stronger and the technique Mirio created in the process.

Tamaki commented how Mirio was always strong since he was a child. Tamaki and Mirio have known one another in the past and the friendship between the two can also be deemed as a close one. The two refer to one another by their first names and were worried for one another when they respectively went through dangerous or emotional situations.

Tamaki and Mirio hold a deep level of respect for one another. Tamaki idolizes Mirio's outgoing personality and tenacity to keep himself motivated and keep a level head, something Tamaki does not possess. Mirio once stated to Tamaki that he was able to give it his all because of Tamaki.

When bringing up the topic of Eri's quirk, Tamaki placed his hand on Mirio and mentioned Mirio's quirk possibly returning as the latter smiled at his friend. [30]

Nejire Hado

Like with Tamaki, Nejire and Mirio have spent three years together studying at U.A. becoming good friends with one another. During their years of study, she and Tamaki have seen the endeavors Mirio had to go through and understood what he went through to become stronger.

She and Mirio have similar energetic personalities which conflicts with Nejire's talkative attitude, much to her chagrin. However, this similar personality also makes it easier for both of them to talk with one another, unlike Tamaki's quiet nature.

Izuku Midoriya

Prior to The Big 3's introduction, Mirio went out of his way to talk with Izuku. He is rather friendly to Izuku, who at first found Mirio to be strange. After witnessing Mirio's power and technique, Izuku grew to admire Mirio, even thinking that he already seems to be like a pro-hero in the way he talks.

Mirio seems to hold him in high regard, despite only having just met and Izuku being a first-year. When All Might asked if Izuku was suited to an internship with Nighteye, Mirio said that he had been thinking Nighteye would like Izuku from the very beginning. Mirio is eager to help Izuku succeed, offering lots of tips and bits of advice before introducing him to Nighteye.

It is currently unconfirmed how much Mirio knows about Izuku and One for All. He seemed certain that Izuku would meet Sir Nighteye, All Might's former sidekick, and did not look surprised when the retired No. 1 hero summoned him and Izuku to ask him to intercede for the latter. Mirio also took notice of the scars on Izuku's arms, which were caused by One for All.


He met her while he was on patrol with Izuku Midoriya, although they do not react well. When Mirio finds out about what was happening to Eri, he blames himself greatly and becomes determined to save her. He is the first person to give her hope that she could be free of Chisaki and the Eight Precepts.

Mirio defended Eri and sacrificed his powers to do so, he showed no regret in his choice as it allowed him to get her to safety.

Mirio even has faith that her quirk can possibly restore his lost powers but he is no rush to regain them and does not want her to feel guilty about his condition.[31]

He later invites her to the school festival and holds her in the air for her to see Izuku perform in the play. He also happy to see her smile at the performance.[32]

The two has a great relationship since then, as it's been stated that he's a really good friend of her.[33]

Toshinori Yagi

Mirio respects and admires All Might greatly, even after the latter lost his powers, claiming he could not help being happy after being called in by him. Some of his most outlandish behaviors are similar to the energy of All Might's public persona.

It is unknown if Mirio is aware that he was the top prospective candidate for One for All or of the bond Izuku has with him.

Sir Nighteye

Mirio works under him for his internship. Sir Nighteye views him as a full-fledged student with an immense potential, making him believe that Mirio deserves to inherit One For All.

During Nighteye's final moments, Mirio ran into his room and begged his mentor not to leave as he still had much to learn from him. Nighteye comforted Mirio by using his Quirk one final time to tell him he'd be a great hero in the future.[34]

Because of this, Mirio was assured even with the loss of his quirk that he'd be alright in his endeavors as a hero.

    • Additionally, "Tō" is a possible reading of "ten" (?), possibly referring to the fact he would be the tenth user of One For All if Izuku passed it down to Mirio as Sir Nighteye wants him to.
  • Mirio shares his birthday with Izuku.
  • Mirio's favorite things are ramen and comedy.
  • Mirio's Killing Move: Phantom Menace is a reference to Star Wars: The Phantom Menace, the first film in the Star Wars prequel trilogy.
