Vocaloid "What If..."

Have you ever wondered what Vocaloid would be like if something were different about it?

Well, you're in luck! Cuz I'll write you a fanfiction like that!

Rules

 * You can use any Vocaloids, Utaus, and Fanmades at all.
 * Everything must be canon. No fanon or opinion, please!
 * Bad "what ifs" include:
 * ​"What if Len didn't have a crush on Rin?"
 * "What if Neru and Haku weren't BFFs?"
 * "What if Gumi wasn't Gakupo's sister?"
 * "What if Gakupo liked Miku instead of Luka?"
 * "What if Meiko didn't try to murder Kaito all the time?"
 * "What if Teto wasn't so annoying?"
 * "What if Tei didn't kill Len?" (Okay, when did she do that?)
 * Good ones include:
 * "​What if Rin and Len weren't siblings?"
 * "What if Gakupo wasn't a samurai?"
 * "What if Meiko was an UTAU?"
 * "What if Tei liked Kaito instead of Len?"
 * "What if Miku and Teto were secretly aliens?"
 * "What if Gumi had red hair?"
 * "What if Luka's breasts weren't so freakishly huge?"
 * Don't be afraid to go crazy! You can do a normal one, like mine about Tei liking Kaito, or a crazy one, like mine about Miku and Teto being aliens!
