Denki Kaminari

Since they happened to be seated one behind another in class, they became friends and often make comments to each other. They were later assigned to work together along with Katsuki for the Provisional License Exam. They have similar, congenial personalities, although Eijiro is more boisterous compared to Denki, who is more mischievous.

Katsuki Bakugo

Eijiro and Katsuki are on very good terms with each other. They're often times seen together during class, and despite Katsuki's aggressive behavior, it's been indicated that the two of them are friends. Eijiro has described Katsuki as being "manly," a quality that Eijiro is known to admire.

Katsuki and Eijiro team up

Eijiro and Katsuki team up

Before getting to know each other, it’s suggested that Eijiro did not admire Katsuki, as is seen in the Battle Trial arc. Eijiro criticizes Katsuki’s fighting tactics as “unmanly,” a discredit to Katsuki’s hit-and-run tactic. Later, however, while working together in the Unforeseen Simulation Joint arc, the two of them team up, soon sparking Ejiro’s admiration for Katsuki, and what would turn into a deeper admiration and friendship as time goes on. Ejiro goes on to describe Katsuki as “manly” on a few occasions, a clear sign of respect for his friend.

Due to his upbeat personality, Eijiro is usually unfazed by Katsuki’s abrasive behavior. When Katsuki’s divisive attitude arises, Eijiro often makes an effort to subdue it. Although they’re on good terms and Eijiro accepts Katsuki for who he is, he doesn’t take Katsuki’s behavior lying down. Eijiro has also been known on occasion to criticize Katsuki's demeanor, as in the Provisional License Exam.

He even actively seeks out Katsuki’s presense, asking him to be on a cavalry team with him in the Sports Festival arc, to study together before the midterm, and also teaming up with him during the Provisional License Exam arc. He also invited Katsuki to go shopping with them at the mall after the midterm, but was declined. During the Internship arc, Eijiro finds inspiration in Katsuki, who had praised his quirk in a previous conversation, when Kirishima had been feeling down on himself. 

Eijiro also shows worry and concern for Katsuki, clearly caring about him. During the School Trip arc, Eijiro shows visible worry for Katsuki when it’s announced that the villains were looking specifically for Katsuki. He also initiates the effort to rescue Katsuki after he’s kidnapped.

Tetsutetsu Tetsutetsu

Eijiro and Tetsutetsu

Eijiro and Tetsutetsu happy to see one another

Eijiro and Tetsutetsu initially had a rocky relationship because of their similar Quirks. During the U.A. Sports Festival, they met when they both survived being crushed by a 0-Point Villain.[1] As the festival progressed, Eijiro resented being constantly compared to Tetsutetsu, like when Present Mic gave them similar intros prior to their match against one another. [2]

After Eijiro defeated Tetsutetsu in an arm wrestling match [3], he congratulated the latter on a battle well fought, starting their eventual friendship. In Eijiro's next match, Tetsutetsu cheered for him to knock Katsuki out. [4]

They both proved to be on good terms with each other when they ended up interning together at Fourth Kind's Hero Agency. They were initially surprised to see each other, but instead of lamenting about comparisons, they friendly greeted each other. [5]

Hanta Sero

Eijiro and Sero are good friends with each other. Hanta, Denki, and Eijiro are often seen hanging out together.

Izuku Midoriya

Eijiro seems to be on good terms with Izuku. When Shoto told Izuku that he will defeat him, Eijiro tried to stop any further arguing and when Izuku started to talk negatively about himself, Eijiro tried to encourage him. He also told Izuku that he is envious of his Quirk.

He also seems to admire Izuku's growing confidence and seems to be impressed by his quick thinking and logical reasoning. He also seems capable of understanding Izuku's feelings to some extent, understanding how he felt when he was unable to rescue Katsuki. In the internship Arc, Ejiro and Izuku are shown to be on even better terms than previously, often interacting in friendly ways.

Mina Ashido

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

In chapter 144, it was revealed that Mina was the source of a lot of Kirishima's self-doubts. The two went to the same junior 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 forcing the student and the two bullies to break dance, diffusing the situation and ending the issue. One of Eijiro's friends point 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 and envious of the fact that Mina is exciting and heroic while he is not. This is reinforced 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.

However, in spite of these facts, the two are not particularly close, as they are rarely seen interacting with one another. Mina thinks they are 'horn buddies'.

Crimson Riot

Eijiro idolizes a retro pro hero called Crimson Riot and desires to become a hero just like him. Eijiro chose his Hero Name "Red Riot" to pay homage to him.[6] In middle school, when Eijiro was questioning his dream of becoming a hero, it is old footage of Crimson Riot that reignites his passion for heroism. Eijiro shares many of his values with Crimson Riot, most notably Crimson Riot's high regard for manliness and chivalry.

Tamaki Amajiki

Eijiro and Tamaki have a senpai-kouhai relationship since they both are in internship under Fat Gum's care. Eijiro holds a lot of respect for his senpai as we see him praising the latter abilities multiple times and refusing to let go of the criminal who shot Tamaki in chapter 134. He is also shown to be thankful to his senpai because it's thanks to him if he could join Fatgum team.

Later, in the operation to save Eri, Eijiro express confidence in Tamaki's abilities to take care of three ennemies. In return, the latter respects Eijiro and compares him to Mirio saying they both have a "optimist personality".

Fourth Kind

Eijiro idolizes Fourth Kind and worked under him.

Fat Gum

Eijiro respects Fatgum and picked him for his internship, though he admits that he only picked Fatgum because Fourth Kind was unavailable. Eijiro is impressed by Fatgum's abilities as a hero and takes every advice he gives him really seriously. Eijiro's desire to protect Fatgum allowed him to go beyond his self-doubts and fears, meaning he cares greatly for the latter's safety.
