The last official VOCALOID voicebank for Hatsune Miku (dubbed V4X). Following a similar design to the VOCALOID3, she now has tighter detached sleeves and thigh boots that are see-through. The skirt is still double layered, she has a smaller headset, a white sleeveless shirt and pink hair ornaments (now a single pink square).
The official works are by commissioned artists: iXima.
