In the original novels, Rahanimu was a bounty hunter and was sent along with Dilgear and Vrumugun to capture Gourry, and Lina, and Zelgadiss and bring them to Sairaag by Eris. Rahanimu later teamed up with Vizea but was killed by Zelgadiss in the same manner before Copy Rezo blew up Sairaag. In the manga, Rahanimu formed a partnership with Dilgear to defeat Gourry, Lina, and Amelia but in the end they were easily defeated.
