Dragon Pilot: Hisone and Masotan
A gigantic, flying fish-like monster - classified as a "Giant Organic Transformed Flyer" - large enough to be mistaken for a small island or mountain when at rest. Mitatsu awakens once every 74 years to change its resting place, and the group of OTFs perform their duty to guide him to his next destination without leaving calamity in his wake. Additionally, a ritual performed by a group of miko is needed to safely put him to sleep.
