^ oh i see! thank you for clarifying!
i think part of sony's promotion for chiaki would also be anime tie-ins. all 3 of her singles are all anime tie-ins, lol. she should get better or more well known types of promotion. gundam did good for her debut since it's gundam and all, but i'm not sure gintama helped kanousei girl much, since the ranking's pretty low.
i dunno how popular this "Level E" anime will be, but sony should really branch out more and plan her promotion more carefully. hopefully her debut album can at least make the top 10, whenever it'll be released. i think spring or early summer would fit.
