Advice on how to better describe a character like Nono other than 'the pale white woman with pink hair', or Saber as 'The pale white woman with purple hair'? I can't use their names since Lucas has never met any of them, and unless the characters keep only those clothes on at all times, which is unhygienic, I can't use said clothes to describe them.

Nono is an android (Okay, okay, gynoid. Whatever), which is fairly obvious in and of itself if he happened to see her fight. So you could use that. 

Alternatively, the happy girl that keeps calling Saber her older sister.
