KiriSero

KiriSero is the slash ship between Eijiro Kirishima and Hanta Sero from the My Hero Academia fandom.

Canon
For their Battle Trial, Eijiro and Hanta are paired (together) on Team J as the villain team, against the hero team, Tsuyu and Fumikage (Team H). As the arc took an almost complete center around the sole fight of Tenya/Katsuki vs. Ochako/Izuku, the content of Eijiro and Hanta’s trial was minimal although the two are briefly shown protecting the target of the fight, a bomb. Hanta laces the bomb, as well as the area surrounding it with a web of his tape, while Eijiro stands guard in a ready position. The outcome of the trial remains unknown, as no further expansion is/was made.

In the Cavalry Battle during the Sports Festival, Eijiro and Hanta form a team together alongside Mina and Katsuki.

After his work study with Best Jeanist, Katsuki finds that his hair is stuck in the flat, slicked down style Best Jeanist styled it in during their time together, and unfortunately has to attend class with it. As soon as they see it, Hanta and Eijiro both break out in cackles, simultaneously yelling “HOLY CRAP!! WHAT THE HECK, BAKUGOU?!” (in reference to his hair). Literally shaking from anger, Katsuki commands the two to stop laughing or he’ll ‘kill’ them. At this, Hanta teases, “I’d like to see you try, ‘Pretty Boy’!”, causing Katsuki to become so angry his hair somehow poofs back up to its regular spikes. Seeing this, the boys begin to laugh harder, until Katsuki captures them by the backs of their (uniform) blazers and drags them across the room. Hanta and Eijiro share a slightly remorseful glance between themselves as he does.

As he works up the ability to create Unbreakable, Eijiro flashes back to a day at the dorms; Eijiro speaks down on his quirk, as it lacks the flashy, long-range capabilities that Hanta and Katsuki have. Hanta takes the straw of his juicebox from his mouth to comment that it’s unlike Eijiro to be such a whiner, to which Eijiro replies to give him a break.

After Eijiro returns from his internship (alongside Ochako, Izuku, Tsuyu), he’s crowded by worried classmates. Hanta runs up and throws an arm around him in a side-hug, although his eye gets poked by a spikey tuff of Eijiro’s hair during the gesture. He asks why Eijiro and the others didn’t say what had been going on during their internships, and the he, as well as the rest of the class were concerned. Eijiro apologizes, as they were “sworn to secrecy”.

Fanon
KiriSero pales in comparison to the other popularized slash ships of the BakuSquad, more specifically KiriBaku (on Eijiro’s part) and KamiSero (on Hanta’s part). But the everlasting friendship between the boys is enough to make the ship known, and has sparked a number of fanworks, with 90+ works on AO3. Notably, many of the interactions between the two tend to center around the concept of teasing Katsuki (in a playful/friendly manner, which is something that commonly carries over to fanfiction.
