Nyuu will be singing opera! The song is in German and is called Mein Herr Marquis. Lyrics and translation into English can be found here. It's meant to be a fun, humorous song for Valentine's Day. Her outfit is a purple dress with matching purple earrings that are not over-the-top fancy since she's still only been here for a month (and most of the one million gold from Morganna is going into moving her and Lucy out of the hotel).

The stage will be lit with a backdrop of a formal garden with a fountain. Thanks to her animal magic, Nyuu's asked some nice birds to come and sing along with her during the parts with laughter and when she's holding a note (Disclaimer: I'm not familiar with singing terminology.). They'll be perched on the branch of a tree stage prop.
