I read whispering about A-1 pictures or JC Staff taking this series but so far there is no confirmation, while the cast from the CD Drama remains the same (confirmed), I would like to rad/hear from an official source that the anime will have the same designs used for Denpa Onna which are fair enough to give justice to Buriki's designs.
