Ok, so I'm just curious, but why do people ship Kaito with himself? It's actually kinda funny to me, he's the only vocaloid I've seen that has a pairing with himself. There's even doujin on ebay that has this pairing. They seem to use the project diva modules for the pairings sometimes too. I'm just wondering why if anyone has an answer or idea as to why he has a pairing with himself.
