According to a blog entry on the UP UP GIRLS blog, Saho Akari and Satou Ayano will appear in a drama titled Yuusha Yoshihiko to Maou no Shiro on TV Tokyo.
A set date for their appearance hasn’t been released so we don’t have a clear idea when they might be on but it will most likely be in the next few weeks or sometime soon since the announcement was done about a week ago.
The drama seems to center around comedy with a focus on a more historical theme, although from what I can tell Saho and Satou won’t have that big of a part since the drama already started a few weeks ago, but they may be the main characters in their episode so we’ll have to wait to find out.
Despite not having that much info about their appearance we should find out soon what kind of role they had so hopefully we get to see a clip or two once the episode airs.
The drama airs every Friday at midnight (24:00 JST).
