Heroine Overview

Piece of cake for the world's next hottest hero. Hi there everyone I'm Mt. Lady, and you don't have to worry about this bum anymore.
~ Yu (Mt. Lady) during her debut in the English dub.

Yu Takeyama, also known by her hero name, The Mineyama Hero: Mount Lady, or simply preferred to as Mt. Lady, is a major supporting character from the 2016 Shonen Jump anime and manga series My Hero Academia.

She is a Pro Heroine where she has begun her hero career since she graduated from her respective hero academy. She is currently at No. 23 according to the Hero Billboard Chart JP and then became a member of a team that both Kamui Woods and Edgeshot had formed together, which is named "The Lurkers".

She is voiced by Kaori Nazuka (who had also voiced Toru Hagakure) in the Japanese version and Jamie Marchi in the English version.


Entrance Exam Arc

Mt. Lady made her debut when Kamui Woods was about to restrain the Giant Villain using his arbor in the middle of the fight before she intervene and defeats the villain with ease using her Canyon Cannon, therefore stole his lightning. She then introduced herself in front of the crowd, gaining their attention as the paparazzi arrived, shamelessly taking credit while Kamui was in despair due to failure.

Later on when Katsuki Bakugo was taken hostage during the Sludge Villain Incident, She wasn't able to do anything to help due to the fact there was no space in the alley's area length for her giantess form to take action to save him, being careful not to damage the entire area. When All Might arrived and defeats the Sludge Villain with a Detroit Smash, Mt. Lady protected the civilians with her arms when the impact and wind pressure accelerated as a result from the fight.

Later on, she helped the rest of the Pro Heroes into gather what little remains of the Sludge Villain during the aftermath of the incident.

U.S.J. Arc

She and Kamui Woods were having difficulty fighting against Habit Headgear who was holding a family hostage until All Might shows up and defeats him. She and Kamui were at first thankful of All Might coming to their assistance but then began to complain in their thoughts and worry that their careers in hero work will be put down by him.

Sports Festival Arc

She is later seen with Kamui Woods and Death Arms, as the three of them were assigned to be on patrol duty during the festival as security guards. She was first seen ordering takoyaki in front of a seller, then using her appeal to get her order for free, much to Kamui and Death Arms' annoyance, then seen walking with them while commenting about how the festival is going to be this year while eating takoyaki.

She is later seen discussing with them about both the festival's current competition and the hero business. While discussing throughout the conversation, she apologizes for stealing Kamui Woods' thunder during her debut, sarcastically if implied, but soon changed the subject of asking Death Arms to quit smoking.

During the surveillance duties she took alongside her assigned partners, she watched Denki's fight with Ibara, she was that impressed that she would want the Christian girl for a sidekick before Kamui tells her to get back to work, that was until she didn't listen to him as she continues watching the ongoing battles before watching Momo fighting against Tokoyami next, which then starts to infuriate Woods to remind her about their said duties of patrolling the festival and stated to get back to work on this.

Vs. The Hero Killer Arc

She began her mentorship of teaching Minoru Mineta. But on the contrast to his predictions backfired, instead of teaching Mineta anything related to heroics, she ended up making him her servant of doing some chores she demanded while the latter lazed off reading magazines and eating chips, much to Mineta's disappointment into seeing her appeal in person more instead of anything related to heroics. After the mentorship, she left Mineta traumatized during the experience of working at her agency, but it is unknown what she did to him exactly to be this traumatized.

Final Exam Arc

She and Midnight would then appear for an topic interview on TV regarding about the censorship of Hero Costumes and Midnight's controversial debut. But during the interview she would mock Midnight for her past days as a Pro Hero, insulting about how she "enjoys" the attention and how a woman like her "ages" (unwell if that's what she preferred about), this resulted into them arguing and fighting on television which soon became a desire to Mineta's viewing.

Hideout Raid Arc

She and Kamui Woods would later join some of the Pro Heroes and the Police that were needed in a mission to rescue Bakugo from the League of Villains after the incident that occurred back at the training camp. She was seen at the League's warehouse as she destroys it, then later on she, alongside Kamui, Best Jeanist, and Gang Orca would later restrain all the Nomu while Tiger rescues Ragdoll, found her unconscious and resulted in becoming Quirkless.

As All for One appeared before them, Best Jeanist attempts to restrain him if he tried to activate his quirk but backfired as he attacks at full capacity and will in a single blast, sending both Lady and the rest flying out of mid air and gain injury. But as soon when Mr. Compress attempts to stop Izuku and the rest escaping with Bakugo, Lady makes a selfless act of protecting them as she uses Titan Cliff to block Compress' attack, resulting in being harmed more and went unconscious, later Kamui Woods had helped her and the rest escaped from the scene, where Kamui mentioned he was proud of her doing well during the operation and saving.

Remedial Course Arc

She didn't physically appear but it was mentioned by Denki that Mt. Lady, along with Kamui Woods and Edgeshot, had formed a team called "The Lurkers" ever since the Kamino Raid. Much to Mineta's horror and shocked expression, possibly due to his past experience working for her during his internship that scarred him that very day.

Pro Hero Arc

At the event of the Hero Billboard Chart JP upon All Might's retirement and the recently ranked Pro Heroes, she was first seen being interviewed by the press about her membership to the newly formed team, the Lurkers, feeling "motivated" upon the success of her partners had from rising through the ranks, when the reporter mentions about some rumors of Lady and Kamui dating she declines her answers by mentioning "no comment", but then starts to complain about Kamui Woods getting more recognition than her when she was placed No. 23 in the charts.

Endeavor Agency Arc

She appeared during her time teaching Class 1-A about interacting with the media, using their moves from their quirks to be used to warn villains about their next moves, especially towards of bringing hope to heroes and civilians alike. She was impressed by their skills and moves (especially Todoroki under her own interest), however, Midoriya was an exception when he was too nervous to do anything, but when she mentions about his Quirk in comparsions to All Might, he begins talking about the fact widely, much to her annoyance before showing Black Whip, also to her disappointment and being left unimpressed.

Afterwards, she along with the rest of the Lurkers mentored Denki, Hanta, Ibara, and Mineta for their field training when the Hero Public Safety Commission demanded all schools to get their student heroes to begin the said event as of now (In truth, it was due to the upcoming war between the Pro Heroes and the Paranormal Liberation Front as predicted).

Paranormal Liberation War Arc

She was one of the many Pro Heroes to participate in the war, alongside her teammates Kamui Woods and Edgeshot, as everyone made their preparations within their forces to charge in and raid the headquarters of the Paranormal Liberation Front within the Gunga Mountain Villa.

As they charged and fought against the PLF's many number of warriors within the state, she was seen in her giantess form, taking out most of the enemies until Geten came in. Upon getting up after he attacked her and almost landed on Fat Gum, she furiously punched at the ice Geten made along with him in retaliation.

When Gigantomachia awaken and moves out with the League and Skeptic to where Shigaraki was after he awakened, Mt. Lady tries to hold back Gigantomachia where Midnight and Woods did what they could to help her until the League intervened them, which results Woods burned by Dabi as Midnight dropped down on the ground where she was killed by one of the warriors later on. Upon holding onto the giant for a bit to give time for the students of 1A and 1B to set a trap, as she tries to wake up the unconscious Woods while buying some time.

As the giant fell for the trap, Mt. Lady pushes him to the ground after other several heroes attacked as she forcibly opens its mouth to have one of the students place the sedate into it. Not before long, Gigantomachia pushes aside Mt. Lady after the sedative was placed, and continued roaming to find Shigaraki until it took effect.

During the aftermath, many heroes retired and lose hope after Dabi exposed Endeavor's past and broke the society's belief in heroes. But during the press interview, Mt. Lady, now left with a scar in her left eye and recovering watches the news and continues to fight instead alongside other heroes like Woods, Aizawa, Miruko, and Wash.

Current Arc

After the prison breakout occurred, with villains such as Stain, Muscular (aka Jailbreaker currently), Overhaul, Lady Nagant, and many more. Mt. Lady was later seen with the rest of the Pro Heroes, even Izuku, standing before them was the Creature Rejection Clan's mansion in hopes of finding All for One, only to be shown a video message of him tormenting Izuku and exploding the mansions to endanger the heroes.

Later on they survived and discussed about All for One still on the run while talking about how he'll expose Izuku's Quirk that will all go on to burden him. Upon asking if Nagant has more info about AFO, Endeavor responses to how Death Arms retired two nights ago, having reminiscing about him and other heroes losing hope that they were force to quit their careers. She would then ask why AFO never exposed Izuku yet to the public widely, despite information is being leaked, but upon this, they were then given a call from All Might that Izuku defeated the second assassin after him.


Mt. Lady is viewed by many as beautiful and to her own description: "the world's next hottest hero" but has a twist of vanity, sarcasm, and shamelessness in her nature. She's only in the Hero Business for the fame and attention she seeks, which would be one of the reasons why she stole Kamui Woods' thunder from defeating the Giant Villain, instead of having any intentions of making the world a better world. She is also very persistent when it comes to using her sex appeal and flaunting her body to gain popularity and fanservice, even could've said the same in comparisons of beauty and age to other beautiful and hotter heroines such as Midnight as an example.

However, despite her vanity, she is very selfless, careful, and serious about her job of being a hero, even when she is in her giantess form, she is afraid of causing damage towards the city and tries cautiously to prevent any casualties from her said form, meaning there is so much more to Mt. Lady's character than just her desire for popularity and recognition, everything about her reasons to become a Pro Hero in the first place that describes her does not necessarily mean she is entirely selfish. She was even this decent enough to teach Class 1A about interacting well under the press ever since All Might's retirement and final fight inspired other heroes to do better, as she was one of those examples.

She can also have a very lecherous side when she thought her affection on Todoroki, seeing him as handsome and interesting, which shares a similarity to one of the traits pointing to Midnight's personality, but no entirely upon that standard as it is limited.

But deep down inside, she enjoys being a giantess, getting a thrill from being giant-sized or growing to her gigantic form. However, She also enjoys the popularity and attention that comes with being a famous superheroine whom is rising from the ranks. Despite this, she has a thoughtful heart deep down and is still willing to fight against injustice and crime for the sake of the greater good when that time comes.

She is also very determined to continue fighting, despite her flaws and intentions, she would often put them aside for the sake of others' protection as she was seen recovering from the war. She also happens to be somewhat empathic when she began reminiscing the night Death Arms retired when the backlash from the current state of society gave him and does express some concern for Izuku's safety if he were ever exposed to hold the burden of society as of now.


Yu's appearance is described to be a very, very beautiful and voluptuous woman at a young adult age, yet has a curvy appearance with a set of purplish-pink eyes with pupils that are colored white and eyelashes so elegant. She has very long hair, colored blonde and the size of it reaches down to her hips' area alongside two shorter, curlier strands around her face's frame.

Her costume appears to be a skintight bodysuit, with the set colors being purple and pale around the body's area alongside with orange stripes between the side areas of her gloves and leggings' cuffs, she also wore an domino mask with horns around it.

During the aftermath of the war, Yu now has a scar on her left eye and she wears a costume-themed neck brace.

In her attire as a civilian, her entire face is seen without her mask and wears a plain shirt, winter jacket, tight jeans, and high heels.



  • Gigantification: Yu's Quirk allows her to change her size from small to gigantic in said fact. However, she cannot grow more than near the achieved sizing or massive, only allowing her to grow from her original height of 162 cm or her gigantic height of 2062 cm per size depending. Thanks to a special fabric suit that is her hero costume, she can change her size at ease without wearing clothing that could be damage under the process.
    • Canyon Cannon: When Yu is in her giant form, she can perform an flying kick, which results into bringing enough impact.
    • Titan Cliff: Yu uses this when she grows into her giant form and blocks/headbutts the enemy attack. This move is a defense-type.


Kamui Woods

They first met when she stole his chance on defeating the giant villain he was attempting to restrain it before she mercilessly stole his lighting, gaining credit during her debut but also his, but sooner or later they started becoming partners. They were also seen working together into fighting Habit Headgear.

Later on during the Sports Festival, they both participated for security around the campus alongside Death Arms, however, Kamui shows annoyance to Yu's prideful gain when it comes to free stuff, such as getting takoyaki for free by seducing the worker. While their discussion about the next round of the Festival, Kamui gets annoyed with Yu's apology about stealing his credit, but due to the tone it said sarcastic. Later on Yu teases him about how his quirk nearly resembles Ibara Shiozaki's after watching her performance, but with Yu planning for which student she would choose for the internships, Kamui once again is annoyed and tells her to get on back with working on patrol.

During the Hideout Raid, Kamui saves the other Pro Heroes, even Yu. He tells her she did well while she is unconscious, proving that he shows genuine respect and care for her.

Later on it was mentioned that she and Kamui formed a team alongside Edgeshot, called The Lurkers.

During the event of the Hero Billboard Chart JP, the press interviews Yu about her relationship with Kamui, saying working with him gave her encouragement. It was said that there were rumors about them dating, when she was asked about it she declines immediately, this could be implied that deep down Yu has romantic feelings for him, despite having to complain about him getting more recognition than her.


Yu was never in good terms with Midnight, thinking her opinion on Midnight's reason to become a hero was when she mentioned "I think you just like the attention", which led into an argument between the two but got worse when they compared their own ages towards one another, resulted in fighting during their interview on live television.

But later onward to the Endeavor Agency Arc, she and Midnight finally learned to at least cooperate with one another when she appears in U.A. as a guest to teach Class 1-A into being more confident in front of the media.


Prioritize the rescue... You stupid kids... (faints)

Midnight: What's with you? Trying to pick a fight?
Mt. Lady: Of course not! it's just, how do I put it, I think your amazing... For your age.
Midnight: Are you trying to show that your only redeeming feature is your youth!? Even though you're not that young!?
Mt. Lady: I'm saying that if the older generation tries too hard, then it's hopeless for us younger folks!
~ Mt. Lady starting a fight with Midnight on their interview.
Mt. Lady: Kamui! Kamui! Wouldn't she be good as a sidekick?
Kamui Woods: Yeah, I wish I could've gotten a better look.
Mt. Lady: She seems straight-laced, but she's cute!
Kamui Woods: Hey, get back to work.
~ Mt. Lady and Kamui Woods talking about Ibara Shiozaki's performance.
An important part of being a hero is knowing how to pass idle hours. Do you understand?
~ Mt. Lady doing Mineta's "mentorship" (but in actuality she made him do labor for her).
Reporter: Any words for Kamui Woods?
Mt. Lady: As one of his teammates, I could've been more thrilled for his fast-growing success
Reporter: And reports that you two are dating?
Mt. Lady: I have no comment.
~ Mt. Lady when she was interviewed by the media during the Hero Billboard Chart JP (English dub).


An earlier prototype design of "Yu Takeyama" before given to the character herself.

  • Yu's appearance was meant to be originally used for Ochaco Uraraka, the primary female protagonist. During the earlier work and prototypes of My Hero Academia, Yu was going to be the "Ochaco Uraraka" of the series, but it was later scrapped due to the author, Kohei Horikoshi, saying that a main character having such a Quirk like Yu's would be too troublesome. Later on Yu would exist in the anime/manga as a major character while Ochaco had her original design, quirk, and characteristics.
    • However, she wasn't the only character during the making of Ochako in the prototypes as this character once had an appearance and name similar to hers before the changes.
  • Yu's full name contains the kanji for "tall mountain/mountain peak" (岳), "mountain" (山), and lastly "superiority" (優).
    • But in general, her full real name, Pro Hero alias, and Moves have contained many landform references.
  • Yu is considered to be the youngest female Pro Heroine in the series, alongside Bubble Girl (being the second youngest Pro Heroine, who is 21 younger than her despite being a sidekick according to her status) and Hawks, being the youngest male Pro Hero (due to the fact he started his career off fast at the age of 18, later on advanced to being one of the Top 10 Heroes in the Hero Billboard Chart JP now at age 22 this young and now he is currently 23; while Yu did the same at age 22 during her debut, later on she is now currently 24).
  • Yu's appearance and design might've been inspired by Cassandra Lang, also known as Stature.
