Chiko Shinmoto

Chiko is the elder sister of the Shinmoto siblings and is a 2nd-year college student. She has a blonde hair and blue eyes and is fond of handsome guys. In the first episode of the anime, she doesn't seem to like college because there aren't any handsome guys. Chiko is called an otaku by Chika but seems to hate being called that. Instead, she wants to be called a bishoujo.
