Who Caused a Prank on Vocaloids LE♂N & L♀LA?

Hi, everybody, I'm Kimberly Jordan, preferably known as Kimberly AJ, and I'm the master of the Great Crossover. So far, I solved the voice actress of Sora Haruno, one of the many Vocaloids worldwide and it's entertainer Kikuko Inoue from Japan. I'll be typing it in her lifetime page so it'll be complete.

LOLA (offscreen): Master! *approaching* Master!

Kimberly Jordan: What is it, Lola?

LOLA: Something happened to me and my Leon when we were going to kiss each other as usual. Leon, can you tell her something?

LEON: Well, I---*speaking gibberish*

Kimberly: I don't understand what he's saying.

LOLA: He says that something tampered with his tongue he couldn't speak clearly at all. As for me, I've got a rock on my foot, literally. *struggles to get it off* Oh, God, it's too heavy! How am I going to get it off?

Kimberly: Don't worry, Lola, I'll get my daddy's tools to bust that rock off of your foot.

LOLA: Then I need somebody else to undo this damage... please~!
