Merry Christmas!
Chibi Miku, Neru, Teto, and Suzu say: "Meri Kurisumasu!"
As a matter of fact, ALL the Vocaloids have something to say:
This is the first time I’ve seen ALL the Japanese Vocaloids together in one song.
That’s all I have to say. Everyone have a very merry Christmas, and I hope Santa gave you lots of good stuff. ;)
