KiriMina

KiriMina is the het ship between Eijiro Kirishima and Mina Ashido from the My Hero Academia fandom.

Canon
Eijiro gets along well with Mina despite not interacting with her as much. The two collaborated together on Team Bakugo during the Sports Festival arc and seemed to work well. Kirshima and Mina have a quiet and subtle history together, yet they keep it between themselves for the most part. She'll occasionally check on him and show concern, seeing if he's overcome his old-self.

They both attended the same middle school, Mina was the rising star of their school, while Eijiro was often picked on and teased for having a 'weak quirk'. Ashido was basically the embodiment of everything that a modern-day pro hero is, she was essentially perfect, while Kirishima was like the embodiment of old-school outdated heroes, where popularity and flashiness didn't matter, it was just about being heroic and manly. One of Eijiro's buddies points out that Mina herself is very athletic, outgoing, strong and eye-catching. Then he goes on to say that Eijiro and the others are boring and wouldn't cut it with today's societal standards of being a pro. Eijiro seems to admire Mina for how naturally amazing she is, but also begins to feel self-conscious, thinking of himself as dull and useless.

This is later reinforced when he attempts to stop a villain, Gigantomachia, but his legs freeze up in fear and he is unable to move. Mina shows up and stops the villain herself, leading it to a fake direction so that the villain could leave their classmates alone and they could get away safely.

Eventually, Eijiro goes to the girls from that incident as well as Mina Ashido and he apologizes to them for his cowardliness. Later on, both Ashido and Kirishima take the U.A. entrance exam together, which both of them end up passing. On their first day of high school, Kirishima goes through a complete appearance change, dying his hair red and spiking it up in a style that is inspired by Crimson Riot. His hairstyle also appears to have two little horns. Mina picks up on this and calls themselves 'horn buddies'. It's at this moment that Eijiro vows to say goodbye to his pathetic old-self and swears that he's gonna be the kind of hero that never has any regrets.

The past incident has really taken a toll on Kirishima, the guilt was eating him alive, and Mina picks up on this so she lightens the mood and teases him, poking him repeatedly and telling him not to overload himself with pressure. She expresses concern for him by doing this in her own playful way. She asks him how he's going to move on and say goodbye to his old self if he's still pulling the same-old gloomy face as before. She then smiles at Kirishima and tells him to tell her when he really does overcome his regrets from the past and his old self. He smiles back at her in agreement and apologizes.

Fanon
Kirishima's prototype was revealed to have gone to U.A. to impress a girl from his middle school. Because Mina is the only known character to have gone to his middle school, many fans started speculating that Mina was the girl he had a crush on and was trying to impress.
