Zatch Bell! Mamodo Fury (金色のガッシュベル!! 激闘!最強の魔物達, Konjiki no Gash Bell!! Gekitou! Saikyou no mamonotachi, lit. Golden Gash Bell!! Clash! Strongest Demons) is a fighting game released on the PlayStation 2. The original Japanese version was published by Bandai at the end of 2005, after merging with Namco but before the formation of Namco Bandai Games. The subsequent international releases and the GameCube versions were published under Namco Bandai Games. The game is based on the Zatch Bell! franchise.
Every 1,000 years, 100 mamodo children are sent to earth. Each mamodo child comes with a spellbook, which will unleash strong powers when read by a human partner. The mamodo and human will then battle other mamodo for the title of the next "Mamodo King". If the spellbook is destroyed in battle, a mamodo will lose all chance of becoming King, and will return to the Mamodo World forever. The last one standing without their book burned will be crowned the King.
Kiyo Takamine is a 14-year-old Japanese boy genius who is bullied at school for his intellect. As a result, he is socially inept and has trouble making friends. Concerned, Kiyo's father, a professor teaching in England sends a young boy named Zatch Bell to help him. Kiyo's father found Zatch dying in a nearby forest, where he had lost all of his memory except for his name, and also with the young boy, a mysterious book. It is soon discovered that Zatch is one of the mamodo competing for King, and after seeing a kindhearted mamodo named Kolulu fight against her will, he vows to become a benevolent Mamodo King and stop the fighting.
Zatch Bell!, known in Japan as Konjiki no Gash!! (Japanese: 金色のガッシュ!!, Hepburn: Konjiki no Gasshu!!, lit. Golden Gash!!) is a shōnen manga series written and illustrated by Makoto Raiku. It was published in Shogakukan's Weekly Shōnen Sunday. The series follows Kiyo Takamine and his Mamodo (魔物, Mamono, lit. "demon") partner Zatch Bell as they try to win the tournament of Mamodo battles in order to make Zatch the king of the Mamodo world.
The manga was later adapted into a 150 episode anime TV series titled Konjiki no Gash Bell!! (金色のガッシュベル!!, Konjiki no Gasshu Beru!!, lit. Golden Gash Bell!!) by Toei Animation. The anime was directed by Tetsuji Nakamura. Konjiki no Gash Bell premiered on Fuji TV on April 6, 2003 and ran until March 23, 2006. In addition to an array of licensed merchandise, the series also spawned a series of video games, and two animated films.
One hundred Mamodo go to Earth every 1,000 years to battle to be the king of the Mamodo world. Each Mamodo needs a human partner in order to use his or her spell book, a book that seals the powers of the Mamodo. When read aloud, the spells are cast by the Mamodo producing many effects. If the spell book is burned, the Mamodo is forced to return to the Mamodo world, and they lose all claim to the position of the Mamodo king. While the spells in each book typically are different for each Mamodo, there are Mamodo that share spells, like Zatch Bell and his evil twin brother, Zeno Bell. The human and their Mamodo gain these spells through experience and hard work. The last Mamodo standing without their book burnt is the new Mamodo king.
