"Heh heh heh... Failure is the mother of invention, Power Loader sensei. Thomas Edison once said that. Just cuz a creation doesn't work as intended doesn't mean the effort is wasted..."

Mei Hatsume to Power Loader in "Creating Ultimate Moves"

Mei Hatsume (発目明 Hatsume Mei?) is a student of U.A.'s Department of Support from Class 1-H.[1]


Mei has quite a fit physique with a very round chest. She is around the same height as Izuku. She has somewhat messy and curvy pink shoulder-length hair, somewhat resembling dreadlocks or bananas, and yellow eyes. Also, she has a crosshair-like design on her eyes. She usually wears protection goggles over her head.

During the Sports Festival, she wears U.A. gym outfit with her sleeves rolled up, added gizmos, and fingerless gloves.


Mei is a smart, odd, and easygoing girl, though at times inconvenient. She loves creating gadgets, which she refers to as her "super cute babies". Mei also has the habit of "going straight to the point".[2] She is also very shameless and opportunistic when it comes to advertising her inventions.

Mei shows no fear when it comes to failing, seeing it as an opportunity to learn and do better next time, which is why she doesn't mind when her inventions fail. Mei can be seen as self-centered due to putting her love of inventions and gadgets above others, but this selfishness is not negative but rather out of motivation to improve herself.


Sports Festival ArcEdit

Mei participates in the Obstacle Race, using her Wire Arrow and Hover Soles to easily get through during the tightrope abyss, as she explains students of the Department of Support have permission to use customized uniforms and gadgets since they do not receive formal combat training like students of the Department of Heroes.[3] She eventually finishes the race, placing 41st,[4] allowing her to continue onto the next event, the Human Cavalry Battle.

Mei's Equipment

Mei showing off her "babies".

Mei offers to team up with Izuku and Ochako, startling the former for "being too close". She says that she can get a lot of attention from the student who places first and that this way her gadgets can better get noticed by a company. This confuses Ochako, but Mei ignores her. Mei then starts explaining to Izuku about the Department of Support and shows him her "babies", among which he recognizes a jet pack based on Buster Hero's Air Jet, and Izuku comments he is his fan too. She then prepares to tell him what her Quirk is.[5] After Izuku recruits Fumikage to join the team, they are seen in a warhorse formation.[6]

Juuzou's Quirk

Team Midoriya unable to move.

The event begins and Mei along with her teammates are almost assaulted by Tetsutetsu's and Tooru's teams. Mei and her team try to escape, but they find themselves unable to move because of Juuzou's Quirk.[7] Izuku tells Ochako and Mei to look away and uses the jet pack that Mei gave to him earlier, allowing Mei and her teammates to escape into the air. When Kyouka attacks them Fumikage uses his Dark Shadow to defend his team. Mei and her teammates land safely thanks to Ochako's Quirk and equipment attached to her legs (courtesy of Mei). Izuku praises Mei and her gadgets for giving them greater maneuverability. Then, Mei and her teammates are attacked by Team Tetsutetsu again but Fumikage uses his Dark Shadow to block them. Suddenly, Mezou and his team attack them. Under pressure, Izuku decides to escape by flying into the air, but they are suddenly attacked by Katsuki. Fumikage uses his Dark Shadow to block Katsuki's attack. After landing, Mei and her teammates are confronted by Team Todoroki.[8]

Team Midoriya's Stance

Team Midoriya prepare to face Team Todoroki.

Denki unleashes a large amount of electricity from which Fumikage's Dark Shadow protects them. Afterwards, Fumikage tries to attack Shouto with Dark Shadow but Momo uses her Quirk to block Dark Shadow's attack. Mei's team continues battling Shouto's team with them holding their ground. However, Tenya uses his new move Recipro Burst which allows Shouto to snatch Izuku's 10-million headband in an instant, which surprises Mei. As Izuku orders his team to after them, Fumikage advises that they go after another team, but Izuku replies that he does not know the point distribution of the other teams. After Ochako pushes her team forward and encourages Izuku to get back the 10-million-point headband, Mei and her team faces Shouto's team in one final clash.[9]

Team Midoriya Advance

Team Midoriya advance.

Izuku manages to take one of Shouto's headbands, thinking it is the ten-million-point one. However, Izuku is shocked to see that the headband he took is not the ten-million one and it is instead a seventy-point one. For the last ten seconds, Mei and her team try to attack Shouto's team again, with Fumikage using his Dark Shadow to protect his team from Denki's electricity, but the time ends and with that the Human Cavalry Battle is over. Izuku tries to apologize to his team, but Fumikage reveals that he was able to take a headband from Shouto and thus thanks to his and Izuku's actions, Mei and her team place fourth, allowing them to advance and participate in the final event.[10]

After a short break following the completion of the Human Cavalry Battle. It is announced the 16 students who made it through, will face each other in one-on-one combat.[11]

When the 16 match-ups are announced, she goes to meet her opponent, asking if he is Tenya, to which he replies he is.[12]

Mei Leaves The Match

Satisfied Mei leaves the match.

When Mei and Tenya begin their fight, Tenya reveals she granted him support items to use during the match. While Tenya begins running towards Mei, she explains to him about the equipment on his legs. With her Hydraulic Attachment Bar, she manages to evade Tenya, and then uses her Quirk to spot the support company representatives. For the next ten minutes, Mei continues her fight while explaining the features of her items to the audience using a mic attached to her headgear. Satisfied that everyone has been able to view her inventions, Mei steps out of bounds and eliminates herself from the tournament, allowing Tenya to advance to the next round. Mei thanks Tenya for allowing her to use him and apologizes for it, although it did not actually look like she really meant it, much to Tenya's annoyance.[13]

End of Term Test ArcEdit

Mei is mentioned by All Might; according to All Might, Mei's High Density Weights won a competition.[14]

Hero License Exam ArcEdit

Mei appears again as Izuku visits the workshop to improve his hero costume. An explosion catapults her through the door as Izuku tries to enter. She recalls Izuku only to turn away and tell him that she's busy in the workshop. Upon hearing that Izuku wants to upgrade, she turns all her attention to him though. While Power Loader and Izuku discuss how they can upgrade his costume, Mei grabs onto Izuku to feel his muscles. Mei equips Izuku with her 49th invention, a Power Suit. However, the armor moves independent from Izuku and hurts him, causing her to apologize for programming the motion range wrongly. Upon hearing Tenya's request for a gadget that lets him cool his legs, Mei equips him with her 36th gadget, an armbrace that supresses heat generation, which promptly Tenya into the cieling. When Tenya complains, since his quirk is located in his legs, she reasoned that he could run with his arms, to cool his legs. Powerloader scolds her for her carelessness and she returns to her work. Shortly after she tries to improve Uraraka's costume with some gadgets, much to Uraraka's dismay.

In the end, Izuku settled for an armbrace that reduce the strain on his arm and boots with a coil-mechanism, that absorb some of the impact force of his kicks.

However, she proves to be a capable combatant as seen in her match against Iida, where it lasted for ten minutes with Iida unable to do anything to her despite his speed advantage and only winning when she forfeited.

Sports Festival ArcEdit

Relationships Edit

Izuku Midoriya Edit

Mei and Izuku first met during the U.A. Sports Festival. Mei took an interest in Izuku when he got first place in the Obstacle course and as a result, got the ten million point headband. She saw this as an opportunity to bring attention to her inventions by using Izuku and approached him before the Human Calvary Battle. In return for joining his team, she offered him and the other teammates support equipment to aid for their battle.

After the U.A. Tournament, the two would not meet again until Izuku wanted Power Loader's help in improving and redesigning his costume. Mei recognized him during their second encounter, but does not remember his name and dismissed it in order to go back to her inventions only to return her attention back to him when he brought up his purpose for entering the workshop. She provided Izuku some options for improvements on his costume and created Izuku's Costume Gamma.

Overall, the two generally get along well. Izuku has no problem talking with Mei during their first encounter. They got acquainted over a jetpack Mei created that was similar to a hero Izuku was familiar with. Izuku also appears to tolerate Mei more than some of his classmates like Iida and Ochako.

Power Loader Edit

Mei frequently invents a lot of inventions at U.A., even during her break. As a result, she spends a lot of time in Power Loader's workshop and in his company. Power Loader tolerates Mei's presence and values her importance to the students. However, when her behavior gets out of hand, he tries to keep her in line much to Mei's dismay. Despite that, the two are friendly with one another, with the occasional petty arguments that happen because of Mei.

Tenya Iida Edit

Mei approached Iida before their match with Mei offering Iida support equipment. Iida naively accepted her supposed generous offer, only to realize too late that she was using him to promote her inventions. Despite her apology, Iida dislikes Mei for taking advantage of his noble nature.This dislike still remained with Iida as seen in their second encounter. His dislike for her escalated when she forgot and dismissed his name, and also made him unwillingly use one of her inventions that he rejected. He openly voiced his dislike of her to Power Loader.


  • Her name comes "invention" (発明 hatsumei?) and "eyes" ( me?), but the second and third kanji have switched positions.
  • Mei was originally going to be a male.[20]
  • In the First Popularity Poll, Mei ranked 20th, which ties her with Toru Hagakure.
  • Mei's favorite food is chocolate.
  • Mei likes steampunk style, as evidenced by her usual gadgetry


  • (To Power Loader) "Heh heh heh... Failure is the mother of invention, Power Loader sensei. Thomas Edison once said that. Just cuz a creation doesn't work as intended doesn't mean the effort is wasted..."[21]
  • (To Tenya Iida about using his arms instead of his legs) "If you want to cool your legs, all you have to do is just run with your arms!"[22]
