Nina is a classmate of Ayu. When Ayu first met her, she had lost her "magic computer," and as it turns out, Nina actually comes from another world called the Magic Kingdom! Nina is in fact, a magician, and with the help of her little computer, she can put enchantments on things and people. Although her intentions are usually very good, the results aren't all that magnificent... Nina is currently studying aboard at Ayu's school and lives with a host family (mix of magic and normal human marriage). Nina also has a cat pet, Rio, who can be turned into human form when taking a magic pill. Nina admires Ayu a lot and will do anything to try help her! Nina is also the first one to discover Kaji's true personality. She also likes to refer to herself in the third-person.
Height: 162 cm The popular girl at school who makes friends with the new student at school, Nina, who is a magic girl. Ayu doesn't believe in magic or anything like that, she has to keep her cool to maintain her reputation. She loves to play tennis and has a huge crush on Tetsushi.
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).

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.
