Denki Kaminari/Relationships

Kyoka Jiro
They seem to be good friends and are often seen together. The two heroes-in-training were paired together during the Battle Trial, and the Unforeseen Simulation Joint, showing to work decently well together. Kyoka was especially helpful to Denki at U.S.J., helping him when he thought that he couldn't fight alongside Kyoka and Momo Yaoyorozu without hurting them, but she kicks him into one of the villains, claiming that she can use him as a "human stun-gun". Her quick thinking was very helpful at that moment, as it was very effective against the villains and it gave Momo time to create a protective blanket for Kyoka and herself to use.

Though the two seem to work well together, they tend to argue quite a lot, although this is generally viewed as friendly banter rather than genuine quarrelling. Kyoka will often pick on Denki by saying rude things that will darken his mood as a form of comic relief. She also, more so than everyone else in Class 1-A, happens to enjoy Denki's brainless state, and is often seen in the background laughing at it with the other characters. Despite all this, or perhaps as a result of it, Denki does still consider Kyoka a friend and she views him in the same way.

Denki is very supportive of all his friends, and this includes Kyoka. When Kyoka shows her insecurities around her music hobby, he compliments her, encouraging her to embrace her hobbies publicly.

When Denki begins to panic and fear for his life during the raid on the Gunga Mountain Villa, Midnight tells him to think of the person who matters most to him, and Denki's focus centers on Kyoka, who encourages him and tells him to stay strong. At this point Kyoka seems to be one of Denki's closest friends, and it's likely that Kyoka knows Denki thought about her following Midnight's advice because, as her earphone jacks were plugged into the ground, she spoke up right when Denki looked back at her.

Eijiro Kirishima
Since they happened to be seated behind one another in class, they became close friends. They often make comments to each other. When the students are together, they are almost always standing or sitting near each other, even when they are out of class. They appear together especially often during comedic scenes.

They chose to work together along with Katsuki Bakugo for the Provisional License Exam. After a student from another school defeats Eijiro and Bakugo, Denki stands up against the student to help them. The student taunts Denki by stepping on Eijiro, which greatly upsets him. He ends up defeating his opponent, saving Bakugo and Eijiro.

Overall, they have very similar personalities, both being very positive, friendly, and likeable, although Eijiro is somewhat more boisterous compared to Denki, who is more mischievous. Their similarities personality wise make them able to get along extremely well. They are also similar in the fact that they both get along well with Bakugo, although Eijiro spends a little more time with him then Denki does.

Proof of their friendship is that Denki is the very first one to congratulate Eijiro for his hero debut defeating a villain alone while he was patrolling on his first day of Hero Work-Studies at the Fat Gum Agency, excitedly showing everyone the news of his feat.

Katsuki Bakugo
Denki initially did not like Katsuki, finding him to be an aggressive bully, but Denki has warmed up to him over time, as he feels comfortable openly teasing Katsuki and trying to converse with him. An example of Denki teasing Bakugo is on the bus ride to U.S.J. while Katsuki angrily insulted him.

Denki was intimidated by Katsuki in Final Exams Arc but agreed with his point of mastering his Quirk. As time goes on, it seems Denki has become comfortable around him and considers him a friend despite his violent tendencies and sees his determination to become a Hero is stronger than most. He often hangs around Bakugo and Kirishima, who is especially close with him. He even got away with calling Bakugo “Kacchan”, an affectionate nickname that Izuku Midoriya addresses him by.

In the Provisional Hero License Exam, it is shown that Denki sees Katsuki as a friend when he saves him and Eijiro from another student's Quirk, and respects him enough to stand up for him. He goes up against a powerful student from another school in order to save his friends.

Minoru Mineta
Due to their shared perverted interest in girls, Denki and Mineta occasionally hang out with each other. They both once played a prank on the Class 1-A girls during the U.A. Sports Festival, where they tricked them into wearing cheerleading outfits for their own personal amusement. Together, they tricked Izuku to help persuade Shota Aizawa to give them permission to use the school pool just to see the girls in their bikinis. Although they were both disappointed to find the girls wearing school swimsuits, Mineta was still appreciative that the girls were wearing swimsuits while Denki insisted that he should get some standards.

Denki and Mineta differ in the fact that Denki respects the girls' privacy, and despite being a little perverted, he knows not to take things too far. In one episode he tells Mineta that he's crossing the line when he reveals his plans to climb the wall to spy on the girls' side of the hot springs. He was also shocked when a peephole to the girls' locker room was discovered, while Mineta had no problems with invading the girls' privacy and saw the peephole as a blessing.

They discussed potential Super Moves that they might develop. Denki was jealous that Mineta got a higher grade than him at the exams which meant he was more intelligent.

Mina Ashido
Kaminari and Mina are often seen together and are considered to be friends, although Denki is not seen as frequently with Mina as his is with Eijiro and his other 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.

Hanta Sero
Denki and Sero appear to also be friends, often hanging around and talking to each other, indicating a friendship. They share a very social personality, tending to be among some of the louder and more extroverted boys of the class. They enjoy making jokes with each other, and appear to be very comfortable around one another.

Mashirao Ojiro
Ojiro sits in front of Denki in class and the two are often pictured talking to each other in the background. Denki seems to have a fixation on Ojiro's tail and often plays with it and pets the hair on the end of it. The two of them appear to have become friends as the show has gone on, Denki sometimes confiding in him with certain things.

Momo Yaoyorozu
Denki and Momo had encountered several obstacles together, mostly during the U.S.J. attack where they fought against villains along with Kyoka. In addition, they were also together in Team Todoroki during the Sports Festival. Later on, seeing her fellows having educational difficulties, Momo suggested to help Denki and Mina with their revision. Denki and friends go to the study session, and during their time there their friendship intensifies. After the exam Denki thanks Momo for her help.

It is also seen later in the manga where Denki and Momo were chitchatting and laughing on the sofa, reflecting on the fact that they are good friends.

Fumikage Tokoyami
During the U.A. School Festival Arc, Denki and Tokoyami are shown interacting more with each other. They were members of the A Band, both guitarists for the class's show. Both lads spent hours practicing and learning how to master several techniques and chords of this musical instrument. Furthermore, Tokoyami tells Denki that he is a magnificent friend and encourages him to fight in the battle.

Tokoyami watches Denki charge forward and thinks back to when they practiced together, how he hurt himself strumming the guitar and he offered for the two of them to take a break. Denki said they should keep going a little longer, because he wants to help out Kyoka anyway he can with his performance. From this statement, Tokoyami deduces that Denki is a man who cares deeply for his friends from the bottom of his heart.

Hitoshi Shinso
They have not had much interactions together so far, as Denki talks to Shinso for the very first time in the Joint Training Battle. Despite Hitoshi's cold attitude, and his statement that he was not there to make friends, Denki makes an attempt to befriend him anyways. He tries to be friendly to Shinso, and he defends him when Katsuki describes him as a dead weight for the exercise due to his lack of experience.

They teamed up during the first round. Even though Shinso thinks he was too slow in capturing Jurota and apologizes to his teammates, Denki points out that he did a good job, tells Shinso that he's rooting for him to become a great hero some day.

Seiji Shishikura
Since Seiji watched the U.A. Sports Festival, he was aware of Denki's Quirk being untamed and he taunts him by saying that he can't use his Quirk because it will also hurt Eijiro Kirishima and Katsuki despite of their deformed state. Denki took those insults personally especially when Seiji stepped on Eijiro's deformed body while taunting him. He ends up underestimating Denki which lead to his defeat.
