Mei Hatsume

Mei Hatsume (発目明) is a student of Yuuei's Department of Support.

Appearance
Fitting for a hero-in-training, she has quite a fit physique with a fairly rounded chest. She's around the same height as Izuku. She has somewhat messy and curvy pink shoulder-length hair, somewhat resembling dreadlocks or bananas, and yellow eyes. Interestingly, she has a crosshair-like design on her eyes. She usually wears protection goggles over her head.

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

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

Sports Festival Arc
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. She eventually finishes the race, placing 41st,  allowing her to continue onto the next event, the Human Cavalry Battle.

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. After Izuku recruits Fumikage to join the team, they are seen in a warhorse formation.

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. 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.

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.

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.

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.

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

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.
