Whos this vocaloid character?

She's my fav beside Miku Hatsune or vice versa (not sure which way are u suppose to write her name since the anime expo here at ca [double yay!!] ). She has LONG pink hair,she wears this the same outfit as m.h. only her skirt is sort of knee length with a slit, she wears a black and yellow outfit. Oh yeah, i also want to know alll the vocaloid characters too! Description and everything.
