Chuu is a 1st year who has never told anybody except family her real name. She lives exotically, with her hair dyed a bright peachy pink and her eyes constantly adorning red contacts. Without contacts, her eyes are chestnut brown. Her voice is quite pitchy and whiny. 

In full unit songs she'll be singing as Nico and Kanan, and in Subunit songs she'll be singing as Nico and Ruby.
