Kaji is in the same grade as Ayu and Nina, and is also the school idol. He is considered cool and always has a nice smile. All his fans are constantly giving him presents, and he even has admirers from the 3rd grade. However, this is only his outer mask. Kaji is in reality a normal guy who hates being given presents by people he doesn't know. But he is working hard on his "nice person" persona because the girl he likes, Ayu, once told him that's the way she liked him. He becomes closer to Nina after she discovers his deception. He is an introverted person, and doesn't like giving away his real feelings or thoughts. Kaji belongs to the school's baseball club. His best friend is Tsujiai.
Tsujiai is a classmate of Kaji, Ayu and Nina. He is the head of the male tennis club and is a slightly extravagant person. Ayu seems to hate him because at the start, he always managed to destroy her chances with Kaji one way or another. Tsujiai introduces Nina to Doraemon (which she loves). His best friend is Kaji and he likes Nina which is shown more in the manga than in the anime. He has a cat name Shinnosuke and is the third person to know that Nina was a magic girl because he saw that Rio the cat transforms into a human.
Touma Kazamatsuri is a glasses wearing bookworm, with short, messy dark hair. She dislikes her hair in the morning, as it is a bad bedhead. She also seems to have a connection with a hair elastic. Touma also has a collection of plushies, which sit on top of her bookshelf at home. She prefers to be by herself alone in a quiet place, preferably the library. She also dislikes P.E class. Although Touma is easily annoyed by Torako's interference and she seems to dislike Torako on the surface, she is actually a good friend of Torako's, and cares for her (though she tries not to show it). She and Torako made a promise of becoming mutual friends, when they made a visit to the Kamizono Academy and met each other by chance. Touma has an older sister which she often fights with.
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. Due to this reason, she and Suzume missed the first few days of school as they were very far away from home on the school opening day. She's Suzume's childhood friend. She's 164cm tall and her three sizes are 81-55-82. Her name contains a kanji of tiger (虎, tora?) and the first kanji letter of her name (上) can be pronounced as 'Ue' (West), thus revealing her name's relationship with White Tiger of the West (白虎).

An immortal companion of Yuta. She was raised by a group of old women that kept her captive and incapacitated in a hut. They were really mermaids that sought to eat Mana once she reached her adolescence to regain their youth. She travels with Yuta since, and possesses a large sense of loyalty and feelings towards him, but due to her somewhat naive and spoiled nature, she doesn't seem to truly realize that her emotions towards him are possibly love or just simple affection.
