The manga and anime series Zatch Bell!, known in Japan as Konjiki no Gasshu!! (金色のガッシュ!!, lit. Golden Gash!!) for the manga and Konjiki no Gasshu Beru!! (金色のガッシュベル!!, lit.'Golden Gash Bell!!') for the anime, features an extensive cast of characters created and illustrated by Makoto Raiku. The fictional storyline takes place largely in Japan during the early 21st century and focuses on the eponymous character Zatch Bell; a being called Mamodo with supernatural powers fighting in a millennial, royal tournament; alongside an intelligent teen boy named Kiyo Takamine. The series' plot follows Zatch and Kiyo's adventure together as they fight their way through the tournament until only Zatch emerges on top and leaves Earth for his homeworld, the Mamodo world.

During the tournament, Zatch also interacts and befriends a few other Mamodo, who are convinced that he is the best hope for becoming a "kind king," his long-held goal. Among the Mamodo he collaborates with are Kanchomé, a comical duckling-like Mamodo partnered with Italian star Parco Folgore; Tia, a hot-headed Mamodo paired with a congenial teen idol Megumi Oumi; Ponygon, a pony-like Mamodo who finds Kafk Sunbeam midway in the series; and Wonrei, with whom his partner Li-en is enamored. Together, they encounter and stave off malign opponents: Zofis, who brainwashes his own partner Koko along with other humans to pair them with Mamodo from the previous tournament; Rioh, who callously risks the entire Earth for the crown; Zeno Bell, Zatch's malevolent twin brother; and Clear Note, who subsequently defeats all of Zatch's allies.

The original manga ran for 323 chapters collected into 33 tankōbon volumes from May 18, 2001, to June 18, 2008. Other editions of the series have since been published. The anime was adapted from the manga and aired for 150 episodes over three seasons from April 6, 2003, to March 26, 2006. The anime digresses slightly from the manga's storyline in several aspects, with some events and elements altered, and Clear Note's uprising never seen. The TV series also concludes with only Zatch and Brago left, both who are seen making opening rounds on one another to determine the final contender. Viz Media acquired the English-adaptation rights for both the manga and anime, although only 25 volumes were translated to English, and 104 episodes were dubbed in English.
