Shinmoto Chiko

Chiko is the elder sister of the Shinmoto siblings and is a 2nd-year university student. Chiko is a really energetic girl, but can also be lazy at times. Beside that she is 'obsessed' with handsome guys where you can see in the first episode of the anime, that she doesn't seem to like to go to the college just because there aren't any handsome guys.
