Neito Monoma/Relationships

Katsuki Bakugo
Neito sees Katsuki, along with the other members of his class, as arrogant, and feels that their popularity must be toppled. However, Katsuki didn't give him much attention until he took his bandana in the U.A. Sports Festival’s Cavalry Battle and mocked him for being attacked by villains. This enraged Katsuki to the point that he overlooked Izuku, whom he had his eyes on, in order to destroy Neito's team. Later, after repeated taunting, mocking and copying of his Quirk, Katsuki's rage just grew even further and he swore again that he would become number one, but this time he added that he would be destroying everyone.

Itsuka Kendo
Neito and Itsuka are in the same class. Whenever he decides to taunt Class 1-A for whatever reason, Itsuka will step in, knock him out and apologize for his actions. Itsuka often criticizes Neito quite heavily such as telling him to stop provoking Katsuki and stopped him from picking a fight with Izuku. In spite of this, Neito never seems to have any animosity, indicating the friendly atmosphere between them. She turned him in during the scavenger hunt for being a “perverse person” and taunted him about making enemies with Katsuki while patting his head.

Tetsutetsu Tetsutetsu
Neito and Tetsutetsu are on good terms as classmates. Tetsutetsu also trusts Neito's judgment, along with most of Class 1-B, as he followed his plan to rank in the lower end of the Obstacle Course in the U.A. Sports Festival, and during the Cavalry Battle worked together with him to target Class 1-A's members. During the Cavalry Battle's start, the two also promised to not hold grudges against either regardless of the final result of the game. Much like Neito, it is revealed that he shares the fact he does not want his class to be upstaged by Class 1-A, despite being a lot more tame about it.

Hitoshi Shinso
Upon taking a first glance at the hero-in-training, Neito took an immediate liking to Hitoshi due to the latter's antagonizing of Class 1-A. Neito was happy that Hitoshi was willing to work on a team with him. He expresses empathy for Hitoshi, because like him, he grew up being derided for having a Quirk deemed unsuitable for becoming a hero.

Izuku Midoriya
During lunch time, he intentionally bumped into Izuku’s head and sarcastically apologizes to him, commenting that his head was big. He insulted him and the rest of Class 1-A, saying that they want attention just like the sports festival and when Izuku, Shoto Todoroki and Tenya Iida encountered Stain before being knocked out by Itsuka twice.
