Rin is a bespectacled girl with long dark-colored hair and a conservative fashion sense. Her lady-like aura stems from her background as a girl raised in a traditional Japanese family. Aside from being an obedient grandchild to her grandmother she possesses a strong sense of responsibility and is willing to help others as a normal girl or as a magical girl. Unlike some other magical girls who were forced to take on the duty of being a magical girl, Rin wholeheartedly chose to become one after her meeting with Mosuke and has been living with the timid shikigami ever since.
