When Raiko started making original manga content, he made several one-shots for the shōnen manga anthology including Bird Man (a one-shot story about a young pilot), Aishū Senshi Hero Ba-Ban (a one-shot story about a happy but feeble superhero), and Genmai Blade (a one-shot and two-part story about a medicinal exorcist). In 1999, he created the manga series Newtown Heroes, which was published in Shōnen Sunday Super, a seasonal publication featuring upcoming manga artists and one-shots from the main Sunday book.
Main article: Zatch Bell!Raiku created the manga series Konjiki no Gash!! (金色のガッシュ!! Konjiki no Gasshu!!, lit. "Golden Gash!!"), which was published in 2001 in Shogakukan's Weekly Shōnen Sunday. An anime adaptation of his manga, Konjiki no Gash Bell!! (金色のガッシュベル!! Konjiki no Gasshu Beru!!, lit. "Golden Gash Bell!!") aired in Japan in 2003 and was produced by Toei Animation.

Gaiden: Tomo (金色のガッシュ!! 外伝「友」, Konjiki no Gashhu Beru!! Gaiden "Tomo", lit. "Golden Gash!! Side Story: Friend"), taking place after the finale of the manga.
