"Today's my debut! Pleased to meet you all! You can call me Mount Lady!"

Mount Lady in "Izuku Midoriya: Origin"

Yuu Takeyama[1] (岳山優 Takeyama Yū?), also known by her hero name Mount Lady (Mt.レディ Maunto Redī?) is a Pro Hero.


She has long voluminous blonde hair with two curled strands, and violet colored eyes with white pupils.

Her hero costume is composed of a purple and cream colored skintight bodysuit, that is accented with orange stripes. The bodysuit also has three peculiar orange diamond shaped dots on the purple top that are located under her chest. She also wears a purple domino mask with horn-like protrusions on the sides.


Mount Lady is a young woman who seems to enjoy the attention that being a hero that gives her and she doesn't feel any remorse from having to take that fame from another hero while basking in the glory.[2] However, she is not careless, as shown that she won't transform into her giant form in confined spaces in fear of destroying nearby buildings and she's careful when fighting a villain who has taken hostages. She is also shown to be vain as she uses her sex appeal to further her popularity. Even though she is vain, she has shown to be selfless as she stopped Mr. Compress from reaching Izuku's group even though she was heavily injured.


Entrance Exam Arc

Mount Lady catching a villain

Mount Lady catches a villain.

As Kamui Wood was about to restrain his opponent with his Lacquered Chains Prison move, Mount Lady suddenly interfered in his fight, attacking the villain with her Canyon Cannon move, and subsequently defeating it. She then introduces herself to the awestruck crowd, proclaiming it to be her first day on the job, and is afterwards greeted by photographers and paparazzi.[3]

Later on the same day, when Katsuki Bakugou is taken hostage by a villain, she is unable to do anything due to not having room to move around.[4]

Unforeseen Simulation Joint Arc

She along with Kamui Wood were having trouble dealing with Vihara Headgear, as he was holding hostages. That was until All Might showed up and had beaten him and saved the hostages. Although she and Kamui Wood were grateful, they complained that he'll put them out of a job.[5]

Sports Festival Arc

Sports Festival Security Guards

Mount Lady assigned as a security guard.

Mount Lady is seen outside the Sports Festival, having been assigned to guard security. She comments, while eating takoyaki, that all the professional heroes came to watch the event and notes that this year "is gonna be crazy".[6]

After the rules of the Human Cavalry Battle are explained, Mount Lady, along with Kamui Wood and Deathgoro discuss competition and cooperation in the Hero business. The other hero says that if a hero fails, they loose any chances of surviving, and notes that the Obstacle Race is a perfect example of how sometimes one has to lower someone else to show themselves off, and Mount Lady mentions that she felt bad for taking out Kamui Wood's enemy on her first day of work, also asking the other hero to stop smoking, while Kamui Wood agrees with the hero. Mount Lady then comments that sometimes heroes have to cooperate with their concurrents, and that the Human Cavalry Battle is a perfect analogy to that.[7]

Hideout Raid Arc

Mount Lady joins the Police Force and many Pro Heroes in the rescue operation of Katsuki Bakugou.[8]

At the League of Villains' warehouse, Mount Lady destroys the front of the warehouse. Mount Lady along with Tiger, Best Jeanist and Gang Orca infiltrate the partially destroyed warehouse and apprehend all the Noumus while Tiger rescues Ragdoll. Best Jeanist informs Naomasa that the warehouse has been cleared.[9]

A mysterious man appears in the shadows; Mount Lady sees that Best Jeanist is preparing to attack and warns him that the man could be a civilian. Before the Pro Heroes can act, the entire warehouse is destroyed.[10]

Mount Lady survives the attack thanks to Best Jeanist's quick thinking but is heavily injured. After Izuku and his friends rescue Katsuki, Mr. Compress is flung into the air to catch them. Suddenly, Mount Lady uses Titan Cliff and intercepts Mr. Compress, which causes them to smash into each other, preventing Mr. Compress from getting to the students. Izuku along with Katsuki are surprised at Mount Lady’s intervention. Mount Lady tells the students to escape before falling down and becoming unconscious.[11]

Kamui Woods rescues the unconscious Mount Lady.[12]

  • Her name has the kanji for "tall mountain or mountain peak" (?), "mountain" (?) and "superiority" (?).
  • Her anime voice actress, Kaori Nazuka, also voices Tooru Hagakure.
  • Possibly she is inspired by Western superheroes and supervillains like Stature, Giganta (DC) or Garganta.
    • But more probably with Stature, because she has more similarities.
