Kamakku (カマック Kamakku) and Raion (ライオン Raion) are an ancient mamodo team. They were seen only once, when Dr. Riddles has a flashback of their adventures on the Devolo Ruins. Raion is a bookkeeper which heart is being controlled by Zofis. In order of defeat, Kamakku was the first ancient mamodo to be defeated. Raion's Seiyū is Jun Azumi.
