Mina Ashido/Relationships

Eijiro Kirishima
Eijiro gets along well with Mina despite not being seen interacting with her as much as he does with some of his other classmates. The two collaborated together on Team Bakugo during the Sports Festival Arc and seemed to work well together.

It was revealed that the two went to the same middle school, during their senior year, Eijiro tried to stop two students from bullying an underclassman but did not succeed. Afterwards, Eijiro witnessed Mina step in and solve the issue by getting the student and the two bullies to break dance, diffusing the situation and ending the issue. One of Eijiro's friends points out that Mina is very athletic, outgoing, strong and eye-catching while Eijiro and the others are boring. Eijiro seems to admire Mina for this but also begins to feel self-conscious of the fact that Mina is exciting and heroic. This is reinforced later when he attempts to stop a villain on the same day as the bullying incident but his legs freeze up and Mina stops the villain instead.

Eijiro later apologizes to Mina and her classmates for not being able to do anything to stop the villain. Eventually, he and Mina take the U.A. entrance exam together and pass. On their first day of high school, Eijiro undergoes 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 decides to call themselves horn buddies. It's at this moment that Eijiro vows to say goodbye to his pathetic old-self to her and swears that he's gonna be the kind of hero that never has any regrets. The past incident took a toll on Eijiro's self-confidence: the guilt was eating him alive. Mina realizes this so she teases him and lightens the mood by poking him repeatedly and telling him not to overload himself with pressure, showing concern for him 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. Mina then smiles at Eijiro and tells him to tell her when he really does overcome his regrets from the past. Eijiro smiles back at her in agreement and apologizes.

Mina is shown to express concern for him, checking to see if he's moved on from his past yet.

Recently, Mina unveiled a new defensive Super Move called Acidman. She excitedly tells Eijiro that she created it by imitating his “Unbreakable.” Eijiro seems to be pretty flattered that he inspired the move.

During the Paranormal Liberation War, Eijiro rushed through fire to save Mina from being crushed by Gigantomachia and managed to grab and take her falling 30-liter vial filled with sedative with him, it's later shown that he failed to throw his own vial into Gigantomachia's mouth due to Himiko Toga destroying it by throwing her knife at him so he grabbed Mina's falling vial and threw it into Gigantomachia's mouth while thinking about Mina's chivalrous spirit being in good hands. They survived Gigantomachia's destruction and went back to save other injured heroes together.

Ochaco Uraraka
Mina and Ochaco they are seen together several times and are good friends. Mina was the first of the girls to figure out that Ochaco was in love with someone, and frequently teases her for it. Mina is very interested in Ochaco's love life, and despite her insistence, Ochaco is not overly bothered by Mina's curiosity.

Mina initially questioned Ochaco when she saw her distracted before the Provisional Hero License Exam and quickly guessed that she was in love with someone, suspecting that the boy she liked might be Izuku or Tenya Ida due to seeing her often with them, making Ochaco embarrassed. Mina congratulated Ochaco and Tsuyu when they made their debut as Heroines and reached out to Ochaco after he returned safely from the mission against the Shie Hassaikai.

Before the Joint Training Battle, Mina laughs at Ochaco when she realizes that she knows Izuku's attitude changes and when the training ends, Mina teases her again for grabbing onto Izuku so hard in her attempt to save him, implying that she knows she likes him, which causes Ochaco, along with Izuku, to turn bright red in embarrassment.

Mina eventually confirms her suspicions following a random gift exchange, after realizing that Ochaco and Izuku had exchanged gifts, with Ochaco herself affirming she's in love with him, but decided to put her feelings away for now, which made Mina feel ecstatic for Ochaco loving Izuku. After a session in which the class showcases their progress, she witnesses a touching exchange between Ochaco and Izuku in which the two bump their fists while thanking each other for making one another stronger, which she watches with much joyfulness for them.

For intents and purposes, Mina is one of the staunchest supporters and hopefuls for an eventual relationship between Ochaco and Izuku.

Izuku Midoriya
Mina and Izuku have rarely shared important interaction together but when they do Mina has a playful bounce off of Izuku's muttering, though she doesn't seem to mind it though. Their relationship improves during the weeks leading up to the school festival, when, interested in Mina's dance skills, Izuku asks her to teach him some dance movements that may be useful to his combat style, which Mina agrees.

Mina seems to show respect and confidence towards Izuku, as when she and her teammates were nervous about their battle against Class 1-B, he was the one who encourages them, and they are counting on him to win the round. She is also shown to care for him, as she asked if his Quirk was acting strange. They also work really well with each other, as both of them helped each other in defeating the Class 1-B students. After they won the fifth round in the Joint Training Battle, Mina teases both him and Ochaco for grabbing onto Izuku so hard in her attempt to save him, which causes both Ochaco and Izuku to turn bright red in embarrassment. Although he is currently unaware, Mina supports him and Ochaco and hopes for them to end up together. Despite that, they are on friendly terms.

After battle between Izuku and Class 1-A, Mina pleaded Izuku to come back with them because she didn't want to lose anyone anymore, showing that she cares for him.

Tsuyu Asui
The two girls are friends, as they are often seen talking to each other; they are also on a first-name basis, further reinforcing their friendship. Tsuyu congratulated Mina on advancing to the tournament at the Sports Festival, even though she was angry at her own failure, cheering her on enthusiastically from the stands when he saw her fight and is happy that she wins.

Mina was surprised by Tsuyu's field training with the Oki Mariner Crew and called her time there cool. Despite not being able to go to I-Island, Mina had fun being with Tsuyu and talked animatedly with her and Toru. When Tsuyu participates in the raid against Shie Hassaikai, Mina is concerned for her and was thrilled and relieved when Tsuyu and the other students involved safely returned to the Academy.

Yuga Aoyama
Yuga seems to interact with her more than with his other classmates. Mina often teases him about his stomach aches as a result of his Quirk and also managed to beat him with ease during the U.A. Sports Festival Arc. However, she did look apologetic when she saw that he was dazed from her punching and knocking him out.

A running gag is her interrupting him when he is arrogantly speaking about himself, often making him mad, but they don't seem to be on bad terms.

When learning that Yuga was the traitor who was responsible for the U.S.J. Incident and the Vanguard Action Squad Invasion, Mina was shocked and devastated by this news, being driven to tears by his treachery. Despite this, she comes to understand alongside her classmates that Yuga didn't have a choice and agreed to help Yuga make amends by taking down All For One. Enraged by Yuga's downfall, Mina swears with the rest of 1-A that they'll defeat All For One with a look of fury on her face.

Shoto Todoroki
When the students were moved into the Heights Alliance, during the competition with the dorm rooms, when it was Shoto's turn to show his dorm room, Mina, along with the rest of the girls except Ochaco and Tsuyu, were getting ready to see his room. Mina is one of the girls stricken by his looks, and thinks that Shoto is the most handsome boy in school.

Denki Kaminari
Denki and Mina are often seen together and are friends. They somewhat bonded due to them being the worst students in class in terms of grades. They were partners during the exam before the training camp.

Kyoka Jiro
They appear to be on good terms as they are often seen talking as seen in Vs. Hero Killer Arc talking about their internships. Both tease Ochaco for her affections towards Izuku and like the others, Mina was impressed by Kyoka's voice when she sang before the school festival and described her as "husky and sexy". When learning of Yuga's treachery, she leaned on Jirou's shoulder while crying, demonstrating a level of support between both of them.

Minoru Mineta
Like the rest of the girls in Class 1-A, Mina despises Minoru's perverted attitude towards them and was rightly annoyed when the boy attempted to peek on her and the others through a peephole in the girls locker room.

Outside of this, Mina is well-aware of Minoru's naughty personality and has on occasion used this to motivate and or convince him. During the planning stage for the School Festival, Mina convinced a dispirited Minoru (who couldn't reach the guitar strings due to his small size) to take part by promising him a harem part in the performance, this caused Minoru to quickly come around while in joy and Mina later made good on her promise. In My Hero Academia: Heroes: Rising, Mina tricked Minoru into leaving to assist someone with lost luggage after mentioning that the girl sounded really cute over the phone. In the anime, Mina is also shown throwing a few playful teases to annoy Minoru.

During the Joint Training Battle, Mina is teamed with Minoru alongside Ochaco and Izuku. Mina is thankful when Minoru uses Grape Buckler to shield her from Nirengeki Shoda's attack, although quickly becomes angry again when Minoru used the recoil of this attack to bounce right into her chest area. Mina responds by throwing Minoru with her Acid Layback, causing him to bounce around in a combination Super Move: Grape-Pinky Combo Mineta-Bounce. Despite her team later securing victory, its clear that Mina was still angry at Minoru's scheme and demanded that Vlad King punish him for being “the worst”. Later on while classes 1-A and 1-B socialize in the dorm area, Mina subjects Minoru to the Ludovico Technique as punishment for his actions.

Fumikage Tokoyami
Mina and Fumikage first interacted during their fight at the Sports Festival. Mina was impressed by her Dark Shadow and she didn't get mad about losing to Fumikage and said it was fun.

They have shown good teamwork such as when they faced Gang Orca's Sidekicks in the Provisional Hero License Exam and during the students' counterattack against Nine's team on Nabu Island, where together they faced Slice.

Mina helped him confront Slice by using his Acid on the Villain's hair and when Slice seriously injured Mina, Fumikage became anger and used his Quirk against the Villain. After the fight, while being transported on a stretcher, Mina smiles weakly and lifts her thumb as Fumikage does the same to her Dark Shadow.

Gigantomachia
Mina first met Gigantomachia when she was in middle school. The villain was asking her friends for directions to the Springer Agency, and when they didn't give him directions, he grew angry. It was then that Mina intervened, bravely stepping in and making up some directions. When he left, Mina quickly fell to the ground and broke down in tears of fear.

The memory of this encounter was very haunting for Mina, and during the Paranormal Liberation War, upon recognizing Gigantomachia, she instantly tenses up with fear while some tears come into her eyes, and fortunately Eijiro came in and saved her from the behemoth.
