List of characters

Ayu Tateishi
One of the female protagonists of the story, Ayu constantly tries to stay calm and keep her cool about everything. This is quite a facade for her to keep up, because the only reason she wants to be "cool" is because Tetsushi Kaji (her crush-later on her boyfriend-, and the star of the school baseball team) told her once that he liked how cool she was about everything. (He said this because when given a pop quiz she was the only one in the class who didn't freak out but she was actually just tired.) However, after she met Nina, she was everything but cool and calm. She is the president of the girl's tennis club and one of the most popular girls in the school, and she works hard on keeping up her "cool, calm and collected" reputation.

Nina Sakura
Nina Sakura is a second female protagonist in the story Ultra Maniac. Her first scene is when Ayu Tateishi finds her crying because she lost a small, pink "box". Later, when Ayu finds and returns to box to Nina Sakura, Nina realizes that she has found a perfect person to reveal her strange secret to. She later reveals it to Hiroki Tsujiai who also becomes her boyfriend in the manga. She is often seen in the anime trying to help Ayu with her love life. She'll do absolutely anything to ensure that her friends are happy, even if it means suffering a little grief herself. Nina is very peppy and perky, and she loves sweets. She also enjoys manga.

In the anime, the last of the five holy stones was unleashed when she and Tsujiai were reaching to each other in the dark zone.

Tetsushi Kaji
Considered an idol by the girls in his school, Kaji appears to be cool and always has a nice smile, but that's just his outer shell. In reality Kaji is a normal person who doesn't even like being an idol. He only acts like Prince Charming because Ayu unwittingly stated once that she liked him that way. (Ayu acted "cool" for the same reason). He later explains to Nina that he's being "the nice guy" because of Ayu and that he worked hard for the title. Nina has a crush on Tetsushi during the second book, but she forgets her original feelings for him when she sees how happy Ayu is to be with him. In the 2nd volume, Kaji finally dates Ayu.

Hiroki Tsujiai
Kaji's best friend, who is often seen together with him. He is the head of the boys' tennis club. He is a fan of many manga and has similar taste with Nina. He is very steadfast and has a good sense of self-worth. Hiroki is in love with Nina. He and Nina start to go out with each other mid-way through the series. They continue to date until the end of the series.

Maya Orihara
One of the candidates to be the princesses of the Magic Kingdom and Nina's childhood friend, Maya has a pet chameleon named Lulu. Her hobby is black magic. At the beginning of the story, Maya had a strong rivalry with Nina but in episode 26, the rivalry ends. Maya has a crush on the prince, who loved her since the time from their childhood when they danced together and she saved him, and later marries him to become princess of the Magic Kingdom. She does not appear in the manga, but in the epilogue chapter she is mentioned as the roommate of Nina in Eltoria.

Rio
Nina's pet cat, Rio (called 'Leo' in the English translation of the manga) can change into the form of a little boy, with a magic candy. In the anime, all he has to do is a flip and he becomes human. In the anime, he starts to like Ayu's dog, Tamako.

Yuta Kirishima
Coming from the Magic Kingdom, Yuta and Nina are childhood friends. He is adept enough with magic that he doesn't need a computer to cast spells like Nina does, and teases her about that frequently. He has a kind heart. At first, Yuta appears to show affection for Ayu, but, as Ayu later discovers, he is actually crazy about Nina. In the last episode of the anime, Yuta appears to have some feelings for Luna, but in the manga, he falls in love and goes out with Sayaka till the very end.

Sayaka Nakamura
A beautiful girl at school, who is known as an "ice doll" because she is frosty towards all of her classmates. She is interested in dating Yuta, but has a secret agenda. Sayaka is revealed to be half-witch on her deceased mother's side. She taught herself magic, and as she grew up on Earth, Yuta and Nina could not detect that Sayaka had magic powers. Due to bad experiences when she revealed her powers to friends in the past, she is envious of Nina who has so many magical and non-magical friends. Near the end, she admits her feelings for Yuta, and they get together for real. She is a manga-exclusive character.

Jun Kawanakajima
