Kuu is a ninja from the Shirogane clan. She often gets mistaken for Mizuho, and just like Mizuho, she's perverted, and doesn't want to get caught by other rival ninjas, and has always been on the run from them, until now. She was walking down the nightly city as you run into her.

"Oh, sorry! I-I didn't see you there!" She looks a bit cute.
