Hitoshi Shinso/Relationships

Izuku Midoriya
Hitoshi claimed to be jealous of Izuku's Quirk, as it gives him combat efficiency. On the other hand, Izuku understands Hitoshi's situation as he himself was considered unfavorable due to having no Quirk. Before their battle in the Sports, Hitoshi and Izuku were hostile to each other, but after their battle, Hitoshi seems to have gained respect for Izuku, telling him not to lose too pitifully while Izuku respects Hitoshi's goal to enter the Department of Heroics.

They meet again while Izuku is friendly to him, Hitoshi ignores his greeting. Hitoshi would surprise Izuku after it is revealed he would play a role in a training exercise in the Department of Heroics. The two soon learned they would fight again in the battle of Class 1-A and Class 1-B.

Katsuki Bakugo
Due to Katsuki's attitude towards the non-Class 1-A people, Hitoshi misinterpreted the Department of Heroics as arrogant people.

Mashirao Ojiro
Hitoshi may not like Mashirao, as he called him a "monkey" when attempting to provoke Izuku into attacking him. Hitoshi brainwashed Mashirao into teaming up with him in the Human Cavalry Battle. After being brainwashed by Hitoshi, Mashirao begins to dislike Hitoshi and warned Izuku to be careful in his fight with him. Hitoshi returned this feeling as he claimed Mashirao's decision to resigns from the tournament event to save his dignity, was very foolish in his opinion.

Shota Aizawa
The Hero Class 1-A's teacher who, because of the similarities in their quirks lack of real combat efficiency, having taken note of Shinso during the Sports Festival decided to mentor Shinso. The teacher beginning to pass on his binding cloth techniques to Shinso to increase Shinso's battle efficiency, training him so that he may transfer into the Hero Course.
