usui sachiko

A main character in Mount Celeb Kaneda-San.

Sachiko is one of Mochiko's classmates. A normal, sensible girl and the class rep. She is a frequent target of Mochiko’s outrageous wealth-flexing habits.
She often plays the role of the "straight-man", unamused by Mochiko's bragging and over-the-top schemes.

She's a plain girl with long black hair styled in a pair of twin braids with blunt bangs. She sports a pair of round glasses. Unlike Mochiko, she has a very "slight" figure.

Usui Sachio is her little brother.
