Minoru Mineta/Relationships

Izuku Midoriya
Izuku is a fellow student of Minoru's in Class 1-A. Minoru has come to admire Izuku for his acts of heroism and for believing in his abilities as a hero, although he is somewhat skeptical at first of Izuku's determination.

The two have become friends, particularly following their battle together against the Villain Alliance. It appears he has picked up some of Izuku's habits, as he used his own knowledge of heroes' Quirks to defeat Midnight. Minoru also engages in commentary with Izuku on the first round of the Joint Training Exercise.

Tsuyu Asui
Tsuyu is frequently seen together with Minoru, although she constantly punishes him for perverted behavior or insensitive comments. Tsuyu most often hits Minoru with her tongue.

However, the two seem to be on friendly terms, to a degree. They worked together to defeat several villains in Unforeseen Simulation Joint Arc and he even earned her praise for his ingenuity. They also worked together U.A. Sports Festival Arc.

Momo Yaoyorozu
Minoru is greatly attracted to Momo due to her attractiveness and womanly figure. On the other hand, Momo can't stand him due to his perverted behavior and she is annoyed when he tricks her into falling for his schemes.

Denki Kaminari
Due to their shared interest in girls, Denki and Minoru frequently hang out with each other. They both once played a prank on the Class 1-A girls during the Sports Festival, tricking them into wearing cheerleader outfits for their amusement.

They've also talked about other things, such as potential Super Moves that they might develop.

However, Denki was annoyed when Minoru revealed himself to be very smart in the final exams while he didn't do too well.

Yu Takeyama
Due to his lecherous and naughty personality, originally Mineta chooses Mt. Lady for an internship. Tsuyu immediately accuses him of thinking something perverted when selecting her, although he denies it.

Days later, when Denki asks Minoru about how his experience was with her, Minoru answers while quivering. Whatever he experienced under her gives him nothing but bad memories, and tells Denki that all women are demons who hide their true personalities. The anime shows that what he experienced was essentially being made into her servant, cleaning up and doing other menial labor around her office while she lazed around.

That bad experience continues to affect him, and now hearing his name terrifies him. When Denki comments that she forms a team with Kamui Woods and Edgeshot, Minoru starts shivering.
