BakuJirou

BakuJirou is the het ship between Katsuki Bakugo and Kyoka Jirou from the My Hero Academia fandom.

Canon
The two didn't have much interaction at the start of the series. They were first seen, sitting next to each other on the bus, indicating that Bakugo must've allowed her to sit beside him.

Besides this, the two became friends at the U.A. School Festival Arc when Katsuki played the drums for Kyoka. Instead of rejecting her plea to play the drums like what he would often do to others, he unexpectedly accepted it alongside ranting about his burden. While the Class 1-A Band prepared for the Festival, Katsuki is seen listening to Kyoka instead of shouting like he usually would.

On the day of the Festival, Kyoka is seen giving one last piece of advise to her band-mates, including Katsuki, telling him "not to improvise the music too much" to avoid confusion since not everyone can keep up with the rhythm yet. He slightly smiled after she sang at the end of their concert.

During the Joint Training Arc, the two were in the same group with both Hanta Sero and Rikido Sato. As Katsuki instructed and told them what they needed to do, Hanta and Rikido complained, recalling how egotistical he still is. On the other hand, Kyoka noticed how Katsuki was more willing to contribute with his teammates, as opposed to when he was working with her in the band. When Setsuna tells Togaru to take out Kyoka first, due to how troublesome she is for them, Katsuki dives into the rescue, blowing Togaru away with his blast while at the same time, kicking Kyoka out of the way. Kyoka then remembers Katsuki's words of "saving them" as the latter manages to send Togaru flying with another explosive attack. Meanwhile, Neito noticed Katsuki's sudden decision to save her, finding it interesting. Eijiro then remarks that this was the first time he saw Katsuki throw himself in the face of danger for someone else, making Kyoka the first person he saved. As she regained her balance, Kyoka looked back at Katsuki who tried to fend off Togaru who escaped. She then thanked him for the unexpected rescue, with Katsuki responding, telling her to get back to action. When Katsuki fought with Togaru again, Kyoka shouted out Katsuki's name in concern.

In the My Hero Academia: Smash!! manga, the two were partnered up for the Folk Dance. As the two held hands, Katsuki became very nervous and managed to keep his cool while at the same time, making small explosions with their hands intertwined, causing Kyoka to wince in slight pain. Katsuki then apologized, which made Kyoka look up at him, thinking to herself whether Katsuki was just plain nervous, or because he was with her specifically.

Fanon
Though this ship is a rare-pair, some fans have come to acknowledge Katsuki's efforts for his friends, particularly Jirou. The ship ceased to get much popularity, due to the other popular ships such as KiriBaku, Kacchako and BakuDeku. This ship however, has already gained some ship art and fan fiction of it.
