KaiSai

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

Canon
Upon Shun's first appearance, he had started thinking about the 'Dark Reunion'; an enemy organization he made up. Kusuo, 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 Kusuo, announcing that they're the only ones with these powers. Kusuo 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. Kusuo claims that he is, with no hesitation, weeping in the bathroom.

When he feels a snake actually coming, Kusuo 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, Kusuo is left shocked. The snake then goes for one of the students, although Kaido gets between the two, and Kusuo saves him, by electrocuting it. Everybody cheers for Kaido, and Kusuo leaves, calling him a moron.

Later on, Kaidou started following Kusuo, believing they are already friends. Kusuo claims they aren't friends, though he keeps him under his watch anytime he's in danger.

When Shun was dating Chiyo, Kusuo stayed close by them to check that nothing goes wrong, since he noticed Nendo ate the cookie Chiyo prepared for Shun. At the end, when Shun realized Chiyo made her a cookie, but he never got the chance to eat it, Kusuo somehow felt guilty, and he felt worse when Yumehara told Shun they are better as friends. Kusuo didn't tried to unite them again, but admitted it was a good move since he says love sometimes is hard, and he didn't want to be protecting them anymore.

When the kids finally realized something is wrong with Kusuo, Shun wanted to know what was happening to him. Kusuo didn't want to tell him, but you could see he was sad somehow. Finally when the others calm down Shun to stop asking Kusuo's secret, Shun accepted and told him he would wait for the time he wanted to say it, like the others said. Told them they are really some pain in the neck, smiling and finally accepting they are really his friends.

Fanon
KaiSai is moderately popular, but ships like SaiTeru and KuboKai are more popular in the Saiki K. fandom. That being said, KaiSai still has a good number of fans. Many people ship this because of their funny dynamic, and their friendship. Some people ship it romantically, while other prefer to leave as a friendship, since later Kusuo admitted he and the other are really close friends to him, and he would regret if something bad happens to them. The ship sailed since Shun went to the bathroom and Kusuo followed him, and how Kusuo answered to himself everything Shun was saying in his mind.

In the manga was quite different, since he saw Kusuo teletransportating, but didn't recognize it was Kusuo himself and had the idea it was a sort of alien. Everyone took Shun as a crazy guy, but Kusuo did know about it and helped him that everyone believed him he actually saw it, without revealing it was Kusuo itself.
