Mao Amatsuka

Mao is the older sister of Megumi and the club's president. She is a small girl who has orange hair and brown eyes. She has the habit of biting and picking on Kyouya when she is bored or angry. She can't stand kissing, to the point of carefully choosing shows to watch or books to read without kiss scenes at all and can barely tolerate the idea of a forehead or cheek kiss.
