Ultra Maniac is a Japanese romantic comedy manga series written by Wataru Yoshizumi.

It features two eighth grade students named Ayu Tateishi, a tennis club member, and Nina Sakura, who is actually a trainee witch from the magical kingdom.

A manga adaption began serialization in Shueisha's Ribon magazine from February 2001 until January 2004, published in five collected volumes.

With Miho Shimogasa (character designer of Cutie Honey Flash and one of the animation directors of Sailor Moon) by designing the characters and Animation Production by Ashi Productions (who did with Magical Princess Minky Momo, Magical Angel Sweet Mint, Jankenman, and Flower Witch Mary Bell).

On her way home, Ayu finds a small computer underneath the bench she knew Nina to be at earlier that day.

The former herself had always shunned the ideas of magic and fairy-tales, even admitting she had never read Harry Potter, thus having someone tell her they are a witch might not be something she can easily accept.

As Nina gives up the stones and her dream, the couple's romantic relationship is made official while she stays on Earth with her friends.
