The Zatch Bell! manga (known as Konjiki no Gash!! (金色のガッシュ!! Konjiki no Gasshu!!, lit. "Golden Gash!!") in Japan, Gash! in Germany, 魔法少年賈修!! (Mófǎ Shàonián Jiǎxiū!!, lit. "Magical Boy Gash!!") in China, and 금색의 갓슈!! (Geumsaegui Gassyu!!, lit. "Golden Gash!!") in Korea) by Makoto Raiku was published by Shogakukan on January 2001 in Japan and spanned until December 2007 with 33 volumes along with a side story on March 9, 2011.
The manga was licensed by VIZ Media but the English release was canceled and discontinued after 25 volumes on June 9, 2009. The Italian release by Play Media was canceled after its first four manga volumes due to poor sales. Likewise, the German version Gash!, published by Egmont Manga, was also canceled after seven volumes for the same reason. Fortunately, all 33 manga volumes were localized in France by Kana and in Spain by Norma Editorial. The Chinese (Taiwan) version 魔法少年賈修!! was published by Ching Win Publishing and the Korean version 금색의 갓슈!! was published by Daewon Culture Industry.
Fan scanlations of the original Japanese Konjiki no Gash manga with all 323 chapters can be found on unofficial manga websites such as sites such as MangaReader.
