Unaired episode included in the seventh Blu-ray and DVD volumes.
Haruka is busy working at the agency so she can't help the idols with the preparations for the Christmas Party held by Shining Agency. A lot of memories and information are revealed while Starish is preparing for the party.
I would say this is my favourite episode. Regardless of just being a special, I would say this is also the most funniest one of them all. Mainly because of Kurosaki Ranmaru, and his reaction when “meat” and high grade food is mentioned. It really makes him seem like a completely different character, in comparison to how he acts in the main episodes of Uta no Prince-Sama. Of course overall I think that everyone has a funny character, and this really sets it apart from the main storyline. If you want to have a bit of a laugh, then you need to see this special
