GakuKai

GakuKai is the slash ship between KAITO and Kamui Gakupo from the Vocaloid fandom.

Canon
Kaito and Gakupo are two voicebanks from the voice synthsizer Vocaloid. Neither of them have a canon personality or background, and their relationship and dynamic depends on the song that they sing together. Even so, Kaito and Gakupo has the disadvantage of being from different companies (Kaito is from Crypton Future Media/Yamaha while Gakupo is from Internet Co.). Eventually they don't match in many semi-official stuff. Although Gakupo appears in the manga Hatsune Mix.

Songs
Gakupo and Kaito don't have many original duos, much less songs were they are in love. But it is still one of the most used Vocaloid combinations mostly due the fact that they are two of the most popular male vocaloids. There are a lot of covers of them of songs like Magnet, Matryoshka and Brain Fluid Explosion Girl. There is also some songs that aren't actual Gakukai duets but show us their dinamic. For example, in The Lunacy of Duke Venomania, Gakupo made a pact with the Devil in order to atract all women as possible, until Kaito, dressed as a woman, scammed him and stabbed him in order to get his wife back.

Imitation Black is a saga mostly sang by them. Although is also sang by Len. The saga talks about two vampires that fall in love with a human (Len), but the love between a human and a vampire is forbidden and Len doesn't admit his love for them. In one of the songs, Lovelessxxx, Kaito and Gakupo start a relationship because they thought that Len didn't care for them. Len saw them having sex and he almost try to kill them, but he isn't able to do that and lost his memory at the end.

Fanon
Being Kaito and Gakupo two of the oldest male vocaloids ever created, GakuKai is one of the most popular Vocaloid slash ships, if it isn't the most popular. It has a strong competence against KaiLen for the first place, although their threesome with Len is pretty popular too. It is often paired along with Negitoro, and its main rivals are KaiMiku, KaiMei, GakuLuka and GakuGumi.
