Kageyama Torako
Outgoing and usually the instigator of the pack, she is identifiable by the fact that she does not wear a blazer over her shirt and tie like most other characters. She likes to achieve her objectives in a straight-forward manner and doesn't really seem to mind other people's circumstances. Because she was absent during the first few days of school, she was unwittingly assigned as a member of the discipline committee. She has an older brother Kitsune, whom she apparently holds in very low regard, and an older sister Oniyuri. As she does not have a very good relationship with her family, she often runs away from her home.
Nonomura Ayumi
Popular among boys for having a large bust and a naive personality, her photos are always in high demand. Due to her extreme shyness, she had trouble making friends since the middle school and is most often the victim of practical jokes and mischief by others.
Iizuka Tatsuki
Daughter to the corporate president of E-lectra, one of the biggest electronics company in Japan, she lives in a modest-looking house with a housemaid, separate from her parents due to her father's work. Ever the classy one, she tends to use honorific speech even towards her closest friends and is often annoyed by Torako's mischief.
Saotome Suzume
Torako's childhood friend. She is usually very quiet but possesses monstrous strength and immense apetite. Despite being very athletic, however, she is in distress for looking child-like and not feminine enough. Whenever Torako runs away from her home, Suzume always accompanies her.
