Hatsune Miku is the most popular character from VOCALOID 2, at least that's what I think, not only popular among VOCALOID 2 fans but also very popular among cosplayers, almost all of my cosplayer friends ever cosplaying as Hatsune Miku (that awesome). well I think Hatsune Miku does have a magnetic field that could not be rejected.
And it seems Karen has also been draged into Hatsune Miku's magnetic field, love how she was enjoying his role in this Hatsune Miku Cosplay picture, dramatic lying Pose, soulful singing and the most I like is the background in this Hatsune Miku Cosplay picture that looks very futuristic.
