Mahoujin Guru Guru

"A long time ago, the evil Giri, who controlled devilish black magic, attempted to dominate the world and unleashed many monsters. Confronted by a formidable enemy, the Kodai Kingdom asked for the help of a Dark Magic User from a particular tribe and succeeded in sealing off Giri. However, after 300 years, the evil Giri is now freed from the seal and once again threatens the world. To rid the world of this terror, the chosen Hero and Magic User began their long and tough adventure."

—Episode Prologue

When the King of Kodai makes a proclamation demanding a hero come forward, a village man Bado sends his son Nike to see the local witch so he can take up the call. The witch tells Nike that to combat Giri he needs the power of the magic of "Guru Guru" which the Migu Migu tribe alone could use. Fortunately, it just so happens that the witch has been raising the last of the Migu Migu, Kukuri, in secret. Together, the reluctant Nike and naive Kukuri set out to face the evil Giri.

Mahoujin Guru Guru (Magical Circle Guru Guru) is a 45 episode anime series that follows Kukuri and Nike's adventures. There is also a 38 episode sequel series, Doki Doki Densetsu Mahoujin Guru Guru. Together, these two anime cover eleven volumes of a sixteen volume manga, which has just recently begun to see scanlation by "imangascans."
