; :Mitsuru is beautiful, graceful, admired by many people, but she has a weird problem. As an effect of her mother's "Spartan Love", a single violent movement against her can get her begging sweetly for more. She returns to her normal self once she faints. Her nickname M is the first letter of her name, but also stands for
masochistic. She has an elder brother and sister. She is in love with Amakusa and because of her friendship with both Amakusa and Hijiri this has subjected her to bullying by the other girls in her class. However, she is still admired by the male classmates. She "protects" Hijiri from dogs and considers it her duty. ; :Natsuhiko is a guy who has found out Mitsuru's secret on their first day of senior high school. Even so, he has an equally bad problem. Even the mere glimpse of his reflection can send him into a flying fit about how beautiful he is. He tries to hide that by wearing glasses in school, tripping over any objects at times, avoiding the girls admiration of him and especially mirrors. But he gets his own dose at his mirror shrine in his bedroom, because N is
narcissistic. Natsuhiko is nicknamed as N. He considers Mitsuru his first friend and vows to protect her and later falls in love with her. He gets easily jealous when other males touch or fawn over her, particularly Hijiri who he (Natsuhiko) knows that Hijiri likes her. He is currently oblivious to Hijiri's fear of dogs. ; :Eiichi is Mitsuru's popular senior in school. He's handsome, athletic, and has the style of a strategist. He is also Yōichi's older brother (see
Gakuen Alice). His biggest weakness are dogs and he dramatically screams and runs away whenever a dog is near or the very word 'dog' can send him into a fit. He also knows about Mitsuru and Natsuhiko's secret. Apparently, he is in love with Mitsuru, and though it's unrequited, he still tries to protect her. He just recently found out about Natsuhiko's weakness and frankly asks him (Natsuhiko) if an "N" can love someone other than themselves and claims that he (Eiichi) will steal Mitsuru. ; :Ririka is Mitsuru's friend from the same year. It appears that she is the only normal character throughout the series. ; :Yōichi's is Eiichi's younger brother. He is 3 years old. He appears as a student in the
Gakuen Alice, the latest series of Tachibana Higuchi. Just like Gakuen Alice, he has the ability to see spirits and controlling them. In extra stories, it seems that he is the one who doing work behind Eiichi's work. ; :Reika is Mitsuru's mother. She's a landscape artist. ; :Mitsuru's older brother works as a
dentist. He has an
Oedipus complex that is not so apparent on the outside. ; :Saaki Amakusa is Natsuhiko's mother. She used to be a member of Takarazuka, causing her to display an extreme character by dramatizing every single thing. ; :Noriko is Eīchi and Youichi's mother. Eīchi and Youichi's father died when they are young. Noriko remarried later on. She usually looks very plain and speaks in a weird accent, but her personality drastically changes when she wears make up. ; :When Mitsuru was only 3 years old, her parents chose a person for her to marry. He is now 32 years old. ; :Kazoumi's friend during high school and Nariaki's secretary. ==Media==
