BakuRaki

BakuRaki is the slash ship between Katsuki Bakugou and Tomura Shigaraki from the My Hero Academia fandom.

Anime
Tomura and Katsuki meet each other at the USJ attack, with Tomura fighting on the side of the villains and Katsuki fighting to defend All Might. However, Tomura doesn't take an interest in Katsuki until the UA Sports Festival. He watches the event unfold on television, and takes careful note of Katsuki and his demeanor. That summer, Tomura and the League of Villains make their move, striking UA's summer training camp. Although the students put up a fight, the villains still manage to kidnap Katsuki.

He is brought to the League's hideout, where Tomura waits for him. He asks Katsuki to join their side, and Katsuki spits back that he wants to be a hero. He then chooses to remove Katsuki's restraints so that he may feel like an equal among them. Katsuki immediately retaliates, flying at Tomura and knocking one of the hands (the one belonging to his father) off of his face. Although this greatly angers Tomura, he also sees just how strong Katsuki is. Still wanting the younger boy to become their ally, he asks for help from All For One. Before this can happen, however, All Might breaks through the wall in an attempt to rescue Katsuki.

Kurogiri uses his Quirk to transport Katsuki, Tomura, and the rest of the League of Villains away from All Might. They meet up with All For One in a different section of Kamino, but All Might is right behind them. In the scuffle of the battle, Katsuki tries to fight off the League and separate himself from Tomura. Izuku Midoriya, Tenya Iida, and Eijiro Kirishima arrive to rescue Katsuki from the villains. The League attempt to chase after them, but are stopped by the Pro Heroes.

Tomura and Katsuki meet again during the Paranormal Liberation War. Katsuki works alongside Izuku to protect him and his Quirk from the likes of Tomura, and together they try to fend the villain off. However, Tomura has upgraded and he merely shrugs Katsuki's attacks off. He also tells Katsuki that he's no longer on his "radar". When Tomura attempts to kill Izuku later in the fight, Katsuki jumps in front of the attack and is gravely injured by Tomura instead.

Fanon
BakuRaki is considered a more rarepair in the fandom. People tend to prefer shipping Tomura with Izuku if they like the appeal of Hero/Villain ships, due to their parallel roles in the story. However, the fact that Tomura put so much effort into kidnapping Katsuki and trying to convince him to join the League of Villains is one of the reasons shippers like the pairing so much. The platonic version of this ship is slightly more popular than the romantic one.

Romantic BakuRaki currently has over 100 works on AO3, while platonic has over 150.
