Youko

Youko (last name unknown) is one of the main characters in Mizuki Academy. She is 17-year-old girl who is Keiko's best friend ~ she is a very nice girl, and gets taken advantage of easily. That's why Keiko is the boss of the two when Keiko is the youngest.

Youko has a big sister whose name isn't revealed who looks after her, but she also has parents who are never seen. Keiko is Youko's only friend.

Appearance
Youko is quite tall, with a healthy weight. She has a medium-sized-chest and is very embarrassed of it, and comments a lot on how Keiko isn't embarrassed about her chest. She has long auburn hair that is messy at the front but straight at the back. Youko, like Keiko, always lets her hair down. When Youko is out of school, she always wears her hair in 2 plaits.

Her eyes are sea blue, big and shiny. When she wants somebody to do something for her, she'll give them puppy-dog eyes and act like she's going to cry.
