KaiSai

KaiSai is the slash ship between Saiki Kusuo and Kaidou Shun from the The Disastrous Life of Saiki K. fandom.

Canon
Upon Kaido's first appearance, he had started thinking about the 'Dark Reunion'; an enemy organization he made up. Saiki, next to him, told the readers to pay no attention to him as he was suffering from chuunibyou. Arriving at school, and the students talk about a snake that escaped from the zoo. Kaido steps in, and says that he will defeat it, and as the students leave, Kaido comes back to back with Saiki, announcing that they're the only ones with these powers. Saiki tells him he's not interested. After other students claim that the snake has died, they start making fun of Kaido, which makes him cry. Saiki claims that he is, with no hesitation, weeping in the bathroom.

When he feels a snake actually coming, Saiki goes with Kaido to the bathroom and finds him through the stall using x-ray. Kaido goes to the classroom and stands up to the snake, Saiki is left shocked. The snake then goes for one of the students, although Kaido gets between the two, and Saiki saves him, by electrocuting it. Everybody cheers for Kaido, and Saiki leaves, calling him a moron.
