ROOT played Zero in the musical adaptation of Vampire Knight. She and Akira were guests in Kawaii International’s 19th episode: Boyish Street-Style Kawaii on NHK.
Since I already knew Akira was a girl, then I already suspected that the one playing Zero would be a girl too, and I was right! I can’t find a lot of information on her, but please head over to her official Facebook page if you like her portrayal of Zero! Thanks again to Erica for sending this in!
