...I feel terrible. But. Haku has nothing to do with anime except her art style. I just can't stress that enough for anything related to Vocaloid. shesaderiativeofavocalprogram. ijust. notananimecharacter.
No. Vocaloid is a computer program. Haku is a fanmade derived from Miku. She's meant to represent FAIL, essentially. Crypton, the company that created Meiko, Kaito, Miku, Rin, Len and Luka and put Haku, Neru, Teto, Hachune and Tako Luka in Project DIVA (not to mention, recognized them as fanmades), have said they don't want a Vocaloid anime. Pretty definitive, hm?
