Yu Takeyama

Yu Takeyama (岳山優), also known by her hero name Mt. Lady (Ｍｔ．レディ) is a Pro Hero.

Appearance
Mt. Lady is a voluptuous woman with long, voluminous blonde hair curled into two strands and purple 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

Personality
Mt. Lady is a young woman who seems to enjoy the attention that being a hero gives her and she does not feel any remorse from having to take that fame from another hero while basking in the glory. She is also shown to be vain as she uses her ample sex appeal to further her popularity.

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 harming civilians as she is careful when fighting a villain who has taken hostages. Despite her vanity, she has shown to be selfless as she stopped Mr. Compress from reaching Izuku's group after they saved Katsuki Bakugo even though she was heavily injured from All For One's attack.

Entrance Exam Arc
Mt. Lady first debuted as a new superhero when just as Kamui Woods was about to restrain his opponent with his Lacquered Chains Prison move, she swooped in, attacking the giant villain with her Canyon Cannon move, and subsequently defeating him. 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.

Later, on the same day, when Katsuki Bakugo is taken hostage by a villain, she is unable to do anything because she has no room to move around in her giant form.

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.

U.A. Sports Festival Arc
Mt. 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".

After the rules of the Human Cavalry Battle are explained, Mt. Lady, along with Kamui Wood and Desutegoro 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 Mt. 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. Mt. Lady then comments that sometimes heroes have to cooperate with their concurrents, and that the Human Cavalry Battle is a perfect analogy to that.

Hideout Raid Arc
Mt. Lady joins the Police Force and many Pro Heroes in the rescue operation of Katsuki Bakugo.

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

A mysterious man appears in the shadows; Mt. 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.

Mt. 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, Mt. 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 Mt. Lady’s intervention. Mt. Lady tells the students to escape before falling down and becoming unconscious. Then, Kamui Woods rescues the unconscious Mt. Lady, telling her she did well.
