Her school uniform has a bow tie, a camera around her neck (the glasses of Fortune in the future) and a big belt around her waist.
She was shown at the start of the series as devilish kind of girl. After the incident of the God of Fortune suddenly appear in her glasses, she slowly becoming ladylike to Kuromine Asahi. Her devilish attitude still hasn't change to other people except for Kiryuin Rin as she is being treated as a granddaughter to her.
She is the president of the Newspaper Club, and has used her position to turn it into a supermarket tabloid. Most of the time, though, the newspaper club members do all the work for her. She secretly likes Asahi, but perceives her lack of femininity as a barrier she cannot overcome, and prefers instead to bully and tease him. She wears fake glasses Asahi won at a carnival when they were younger, and they later become the host of a fortune god in training, though this god's attempts to help only end up causing her more misfortune. Mikan has two younger brothers who occasionally appear in the story. She eventually reveals her feelings to Asahi, who turns her down but also reveals that he has always seen her as a girl, and she just never noticed it, much to her own regret. While she generally puts forward a facade of evilness, she genuinely cares about her friends and will do her best to help them.
