Mahōjin Guru Guru is a light-hearted show aimed at older children, although it contains occasional toilet gags and some innuendo that might startle western parents.
Mahōjin Guru Guru is a parody of early Role Playing Games, particularly turn based games such as the Dragon Quest games. The narrator speaks in place of the dialog in such games and this is one of the comedy elements of the show. Often RPG-style information boxes are displayed on screen along with accompanying narration in the traditional RPG style. The overall goal of the main characters, Nike and Kukuri, is to defeat Giri, the ruler of the darkness. Since the anime is based on an RPG, several side quests need to be completed before they are able to locate him.
Nike, (pronounced Ni-keh) is the Hero of the show. Nike's father had always wished to be a hero, but due to the lack of any great evil to fight against he had to give his dream up. Still, he made his son undergo hard training as a child in hopes that one day a great evil would arise and Nike could fight it. Because of this Nike is a competent, although cowardly, fighter, however like Kukuri he is initially immature and unexperienced. Nike is from Jimuna Mura (which translates to Plain Old Town). Initially Nike does not want to be a hero, but his parents end up forcing him to.
Kukuri, Seiyū: Konami Yoshida
Kukuri is a gentle hearted magic apprentice. She has grown under the care of Jimuna Town's witch, who received her when she was a baby from a wandering stranger, supposedly a member of the Migu Migu Tribe. Being the last remaining member of the Migu Migu, Kukuri learns the dark summoning magic only the Migu Migu can use known as Guru Guru, which consists of drawing circles on the ground with a staff. She is eager and shows great affection towards Nike, almost always calling him Hero.
Kita Kita Oyaji Seiyū: Kenichi Ogata
Oyaji (real name Udberg Eldol), or just "Old man", used to be the mayor of the town of Kitano, also called North Town. When the town's typical dance, Kita Kita, could no longer be performed because no more girls were born, he decided to start dancing himself. His dance is often regarded as creepy and disgusting by the other characters in the show. He usually follows the duo of Nike and Kukuri around. He wears a Hula dress and usually finds some excuse to perform his Kita Kita dance, much to Nike and Kukuri's dismay. Apparently he wants to pass on the Kita Kita dance to the next generation and is looking for trainees.
Gipple Seiyū: Urara Takano
Gipple is a small wind spirit who occasionally guides the duo, though he vanishes at the first sign of trouble. He can expand his cloak into a tent and store items in it. Gipple has an anthropomorphic body under the cloak and wears a little loincloth.
Giri is the series' main bad guy.
After having been sealed by Guruguru magic for 300 years he finally returned and is unleashing his army of monsters to take over the world. Since his only weakness is Guruguru magic, he does all in his might to destroy Kukuri, the last Guruguru user in existence.
He is always depicted sitting on a big armchair, completely hidden in a dark cloak with only his red eyes glowing through. In his demonic-looking hand he always holds a glass of wine.
After having been sealed for 300 years, the demon lord Giri reawakens and sends off his monster minions to wreak havoc in the world. King Uruga XIII decides thus to place announcements everywhere in the kingdom in search of a legendary hero who can defeat Giri. In the king's castle a competition will be held to discover who the true hero is. Forced by his parents to go to the castle, Nike first visits the witch's house, where Kukuri joins him. Together they travel around the world defeating monsters, gaining new abilities, trying to uncover the mysteries surrounding the Migu Migu tribe and meeting many friends and enemies.
Nike and Kukuri receive a message from Wanchin, the old leader of the Migu Migu, who tells them they need to find the 4 elemental swords in order to defeat Giri. Thus a new adventure starts.
The end of Manga shows Nike and Kukuri seal Giri, while it is not shown in the animation.
