Shinji Nishiya/Relationships

Mt. Lady
Kamui originally did not believe that Mount Lady is empathetic, as seen when she mercilessly stole his fame. Despite this, they were seen working together in Unforeseen Simulation Joint Arc and stopped a villain and saving people.

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 was 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.

During the raid on the League of Villains hideout, (in the anime) the two rode together in a car. During the last stages of the raid, Kamui Woods rescued Mount Lady and tells her that she did well, showing he now respects and cares for her.

It was mentioned in the Remedial Course Arc that they have formed a team, along with Edgeshot.

By the time of the Hero Billboard Chart JP, their close association led to rumors about them being romantically involved.
