Mashirao Ojiro/Relationships

Toru Hagakure
They are teamed up together as Team I during the Battle Trial Arc. After the villains retreat during the Unforeseen Simulation Joint Arc, Tooru commends Mashirao's strength, while he asks where she was transported to. After she tells him she was in the landslide zone and mentions Todoroki's strength, he comments that he's glad she was alright. During the final part of the Sport Festival, when Mashirao wants to withdraw from the tournament event, she tries to persuade him to reconsider.

Izuku Midoriya
They get along well though Mashirao didn't team up with him since Izuku was a target in U.A. Sports Festival Arc. Despite that Mashirao tried to warn him about Hitoshi Shinso, Izuku also stood up for him after Shinso insulted him. Mashirao worried for him but was relieved he emerged from the fight victorious.

During the Vs. Hero Killer Arc, he was amazed that the latter improved on his quirk and overcame his drawbacks.

Hitoshi Shinso
Mashirao resigns from the tournament event in the Sports Festival due to being manipulated by Hitoshi, wanting to save his own pride and dignity by doing so. As a result of Hitoshi's action, Mashirao has come to dislike him because he prevented him from doing his best. When Hitoshi approaches Izuku, Mashirao warns Izuku not to respond to his provocations.

Denki Kaminari
Ojiro sits next to Denki and are often pictured talking to eachother in the background. Denki seems to have a fixation on Mashirao's tail and often plays with it and pets the hair on the end of it.
