Yu Takeyama/Relationships

Shinji Nishiya
Yu mercilessly stole his fame by taking down a villain in her debut and he was left in a slump as she was praised.

Despite this, they were seen working together in Later, they work together along with Death Arms as security guards during U.A's Sports Festival, where he questions whether she has any sense of shame or pride when she successfully uses her body to be able to acquire an order of takoyaki for free from a vendor.

After the Denki Kaminari vs. Ibara Shiozaki fight, Mount Lady teases that Kamui has a similar Quirk to Ibara Shiozaki's. At one point, she felt bad for stealing his glory though her tone implied she was being sarcastic. During the raid on the League of Villains hideout, (in the anime) the two rode together in a car, and later Kamui Woods rescued the unconscious Mount Lady and tells her that she did well.

It was mentioned in the Remedial Course Arc that they have formed a team.

During the Pro Hero Arc, their close association led to rumors about them being romantic and when questioned by this matter, Yu chose not to comment. She later cried to Death Arms after Kamui became the No.7 hero though called him senpai.

Death Arms
Besides Kamui Woods, she is also see.

Nemuri Kayama
Yu does not appear on good terms with her, as they got into an argument after Mt. Lady made comments on her liking attention. This further escalated with Mt. Lady admitted to looking up but poked at her age, resulting in the two fighting in televised interview.
