This is a CD which came with a movie guide sold at the theatres and
consists of messages from the seiyuus of the main characters (Cyber Team
and Cibire Team)... That was what I thought of it. But there was another
message from Uzura, which is the best of all (her words earned one more
donburi for the CD ^_^).
In any case, this kind of CD, not restricted to the screenplay written
by someone else, is a good way to measure the skill and feel the
character of seiyuu, IMO. Messages from veterans are definitely more
entertaining from younger ones.
