Drifting Dragons, 18

One of the parasitic dragons attacking the dragon-ship Quin Zaza steals Takita's right eye while they are chasing the descendant, a gigantic dragon that falls to Earth from the deep sky where it lived. The entire crew decides to pursue the parasitic dragon to help their crewmate and resolve the situation, but then Windigo, a dragon nicknamed the Devourer of All, appears. Mika and her crew decide to hunt down Windigo to prevent it from ruining the "descent."
