Ultra Maniac

Ayu Tateishi is a well-adjusted middle-schooler in her second year, until the fateful day when she finds a dejected looking Nina Sakura outside of the school. Nina explains that she lost something very dear to her earlier that day. And that she has fallen in love with her. Ayu offers to help Nina, the annoying girl look for her lost item, but Nina seems reluctant to say what the item is that she lost, and runs off. On her way home Ayu finds what seems to be a mini-computer underneath the bench she knew Nina to be at earlier that day. After returning the item to Nina, Nina struggles to decide whether to let Ayu in on the 'big secret' she keeps.

In order to see if Ayu is trustworthy, she starts to follow Ayu around and eventually decides she can trust Ayu. Nina reveals that she is actually from the Magic Kingdom and is a magic girl. Ayu, however, doesn't believe Nina and thinks she is a bit crazy at first. Ayu herself had always shunned the ideas of magic and fairy tales, even admitting she had never read Harry Potter, so having someone tell her they are a witch truly isn't something she can easily accept. After several mishaps with her magic, Nina proves she is a magic girl, and a failure who came to Earth as her last chance to prove that she can get things right. These first mishaps and the fact that Nina has shared her secret with Ayu, Nina attaches herself to Ayu as a friend and does everything she can to help Ayu with getting the attention of her crush, Tetsushi Kaji. As their adventures continue many friends from the Magic Kingdom come and visit Nina to the chagrin of Ayu.

The anime adaptation has a very different plot starting after Ayu and Nina have first met. Instead of coming as a witch failure who is trying to prove herself to be more than she is said to be, Nina has come to Earth to find the five "Holy Stones". She tells Ayu that whoever collects all five will qualify to marry the prince of the Magic Kingdom. Nina's childhood friend Maya is also on Earth from the start, competing with Nina to find the stones. Though Nina does collect them all first, she learns that the prince and Maya are truly in love with one another, so Nina gives up the stones and her dream, allowing Maya and the prince to be with one another, and Nina stays on Earth with her other lovers. Even though she still loves her.

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.

Ayu Tateishi (立石 亜由, Tateishi Ayu)

Voiced by: Yui Horie (TV Series), Satsuki Yukino (OVA) (Japanese); Stephanie Sheh (English)

Ayu is one of the female protagonists of the story. She 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, and later on her boyfriend) told her once that he liked how cool she was about everything. He said this because when their class was given a pop quiz she was the only one in the class who didn't freak out (she was actually just tired). However, after Ayu meets Nina, she is everything but cool and calm. She is the president of the girls' 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.

Tetsushi Kaji (架地 哲士, Kaji Tetsushi)

Voiced by: Hiroshi Kamiya (Japanese); Tony Oliver (English)

Considered an idol by the girls and a role model to the boys in his school, Tetsushi appears to be cool and always has a nice smile, but that's just his outer shell. In reality, Tetsushi is a normal person who doesn't even like being an idol. He only acts like "Prince Charming" because Ayu 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 volume of the manga, but she forgets her original feelings for him when she sees how happy Ayu is to be with him. In both the manga and anime, he and Ayu eventually begin dating.

Hiroki Tsujiai (辻合 宏基, Tsujiai Hiroki)

Voiced by: Susumu Chiba (Japanese); Yuri Lowenthal (English)

Tetsushi'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.

They continue to date up to the end of the series.

Yuta Kirishima (桐島 由多, Kirishima Yuta)

Voiced by: Yu Hayashi (Japanese); Peter Doyle (English)

Yuta is from the Magic Kingdom, and he 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 with Sayaka and goes out with her until the series ends.

Leo (リオ, Rio)

Voiced by: Reiko Takagi (Japanese); Sherry Lynn (English)

Nina's pet cat, Leo (called "Rio" in the English translation of the anime) can change into the form of a little boy by using 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.

Maya has a crush on the prince, who loved her since the time when they danced together as children and she saved him. They later get married and Maya becomes princess of the Magic Kingdom. Her real name is Maya Orphelia. She does not appear in the manga, but in the epilogue chapter she is mentioned as Nina's roommate in Eltoria.

Sayaka Nakamura (仲村 紗也香, Nakamura Sayaka)

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 because she grew up on Earth, Yuta and Nina could not detect that Sayaka had magic powers. Due to bad experiences Sayaka had as a child after revealing her powers, 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.
