Kyoka Jiro/Relationships

Denki Kaminari
They seems 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 working well together. Kyoka has been very helpful to Denki at the USJ, helping him to have more self-confidence about using his quirk. Denki thinks that it can't fight with Kyoka and Momo and he was not able to use it well, but forced by Kyoka to use it, he finally realized that he can fight too and be helpful.

Though the two seem to work well together, they tend to argue quite a lot. Even more likely, Kyoka will tell Denki rude things that will put his mood down. However, Kyoka happens to enjoy Denki's brainless state, finding it uncontrollably funny. Despite that, Denki does refer to Kyoka as a friend and she seems to view him in the same light as she was hesitate to let a villain kill him.

Interestingly, when Denki finds out about her music hobby, and compliments her, encouraging her to embrace her hobbies publicly, Kyoka gets flustered by his praise and rejects his encouragement.

Momo Yaoyorozu
Momo and Kyoka appear to be close friends with each other. Along with Denki, the two battled against the Villain Alliance at the USJ, proving to work well together. Kyoka later asked Momo to tutor her for the end of term test, which she happily accepted.

When the class split up to go shopping for the training camp, they paired up and went off shopping together. As well as this, Kyoka has proven to be somewhat defensive of her. During the summer training camp, she punched Sero for comparing Momo’s quirk ability to convert fat at an atomic level into many different objects, to pooping. She later joins Kyoka's band, playing the keyboard, during the school Culture Festival and they pull of a wonderful performance with the teamwork of all of Class 1-A.

Koji Koda
Kyoka was partnered with Koji during the Final Exams Arc against Present Mic. Although Koji was very shy and terrified of insects, Kyoka's words and example of bravery convinced him to use his Quirk to talk to bugs of the forest. Koji carried an injured Kyoka through the forest to cross the escape gate and together they passed the exam.

Toru Hagakure
They appear to good friends as they are often seen talking. During the Sports Festival, she was put off by Toru's desire to act as a cheerleader after they were tricked by Denki and Minoru. She was also partnered up with Toru in the 'Test of Courage' during Training Camp.

Toru was also thankful for Kyoka halting Minoru's attempted peeping on the locker room.
