Her home town is Saitana. She is in the same class as Michishio and San. Mawari has been friend with Michishio since her early childhood. When they were little they liked playing cards, and this has become their most favorite game. Mawari’s dream is to become a police officer, like her father. Actually, ever since the Edo era (15 century) up until now each one from her family has been in the police. She strictly keeps society’s laws. Smart, shrewd and quite considerate. Always notices even the smallest details.
