KaiLen

LeKai is the slash ship between Kaito and Len Kagmine from the Vocaloid fandom.

Canon
Kaito and Len are both popular characters from the Vocaloid franchise. Many songs have been made using the two of them in the romantic way. However, besides the fan made content, there isn't much content that is canon besides the interactions they have in the Project Diva opening movies. This is because Vocaloids have no canon background, and many Vocaloid fans like to make headcanons for their characters. Fans of Len commonly headcannon him to be in a relationship with Kaito.

Songs
As mentioned previously, many songs have been made using Len and Kaito in a romantic way. One of the most famous songs that have been produced using them is Erase or Zero by Crystal P. The song is about Len and Kaito getting stuck in a time loop, and being faced to confront their feelings for each other. The ending of the song is still up for debate, and fans still theorize this song to this day. Other famous songs include:


 * "The Immoral Memory ~The Lost Memory~" by NatsuP and Haku
 * "FLY AWAY" by ShadowDragonP
 * "Gray Snow" by KID-P, ZankyouP, and CrystalP

Fanon
The LeKai ship is quite popular among the fans and is by far the most popular Slash ship in the Vocaloid fanbase. Despite the fact there isn't many songs depicting them in a romantic way, lots of fanart has been made for the ship. Many people like this ship because of how it looks. Many fans of this ship are already big fans of Kaito and Len, so it would make sense to ship them together.
