Open Invitation + ｳｯｰｳｯｰｳﾏｳﾏ(ﾟ∀ﾟ) (Sugarmint)

From Youtube: http://www.youtube.com/watch?v=ERIyOhDM7EcThis is the song "Open Invitation" originally sung by Cindy, and performed by Mai Shizuoka and Hatsune Miku for this video.The performance is similar to the 7th ending from "Urusei Yatsura". Too many choreography and a good colors choice.Bonus Track: The song "Caramelldansen", which no anime character have resistance. Additionally Mai-chan, belonging to "Sugarmint Crossover, not resisted this catchy dance track.
