Pro Heroes#
Kamui Woods#
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 U.S.J. Arc and stopped a villain and saving people.[1]
Later on, 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.[2]
After the Denki Kaminari vs. Ibara Shiozaki fight, Mt. Lady teases that Kamui has a Quirk similar 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. Kamui Woods later rescued the unconscious Mt. Lady and tells her that she did well, showing he now respects and cares for her.[3]
It was mentioned in the Remedial Course Arc, that they have formed a team with Edgeshot after the raid on the League of Villains hideout.
By the time of the Hero Billboard Chart JP, their close association led to rumors about them being romantically involved. Yu was speaking to reporters and told them that being on the same team as Kamui gave her a lot of encouragement which causes one of the reporters to ask if the reports of an alleged love affair were true. She smiles and declines to comment.[4]
During the Paranormal Liberation War, Kamui called out her last name out of concern for her when she was tossed aside in her struggle to stop Gigantomachia from running to where Tomura Shigaraki is fighting Izuku Midoriya and his allies. She later carries an almost unconscious Kamui, who was burned by Dabi in a surprise attack, on top of her head and managed to latch herself onto Gigantomachia's left leg while her senior uses his Quirk to bind her arms to it.[5] Yu is exasperated at how unstoppable Gigantomachia is and shouts for Kamui to wake up.[6]
Death Arms#
Besides Kamui Woods, she is also seen associating with Death Arms. During U.A.'s Sports Festival, she was annoyed by his constant smoking while he was seen questioning if 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.
During the Pro Hero Arc, Mt. Lady cried and ran to Death Arms for comfort about Kamui being ranked in the top ten. This showed they get along well.[7]
During the Dark Hero Arc, Mt. Lady was shown to be visibly saddened to hear Death Arms had retired due to excessive criticism from the public.[8]
Midnight#
Yu did not appear to be on good terms with her, as they got into an argument after Mt. Lady made comments on her liking attention. This further escalated when Mt. Lady admitted to looking up to her, but also poked fun at her age, resulting in the two fighting in a televised interview.[9]
By the time of the Endeavor Agency Arc, the pair had shown to have at least learned to cooperate better, as they both took part in interviewing Class 1-A.
After Midnight's death following the Paranormal Liberation War, Yu ultimately shows that she did respect her, as she held her mask during her time recovering and later continues fighting as a hero to honor her memory.
Eight years after the Final War, Yu is seen wearing a new costume and her new mask shares some similarities to Midnight's mask.
U.A. High School#
Minoru Mineta#
Mt. Lady has managed to implant a strong fear in Minoru's heart, to the point where she is probably the only female character that he doesn't have perverted thoughts about anymore.
Minoru decided to choose Mt. Lady for the Hero Agency Internships due to his lecherous and naughty personality, likely thinking that he would enjoy his time with her.[10] In the end, Mt. Lady made Minoru her servant, and had him clean up and do other menial labor around her office while she lazed around,[11] although she surely forced him to do even worse tasks as since he returned to U.A., Minoru has had nothing but bad memories of his internship.[12]
The bad experience he had continues to affect Minoru, and now just hearing her name terrifies him. When Denki comments that she forms a team with Kamui Woods and Edgeshot, Minoru starts shivering upon seeing them with her.[13]
When they meet again, he is alarmed to see her and immediately points out that Mt. Lady is the most "showbiz" hero out there. Mt. Lady ignores his protests and encourages him and his class to try their best for the "Hero Interview Training".[14]
Shoto Todoroki#
During the Hero Interview Training lesson, Mt. Lady chose to interview Shoto first and complimented him on his handsome appearance. She is shown to find his denseness cute and develops an interest in Shoto while saying that he should smile more. Her attempts at playfully flirting with him completely fly over his head though, causing her to move on with interviewing the other 1-A students.
During the Final War after Shoto seemingly defeated Dabi, Yu confessed that she was initially worried, as she thought Shoto wasn't the type to pay attention, but he ended up proving her wrong, causing the giantess hero to commend him for his victory.
