Drifting Dragons manga volume 13 features story and art by Taku Kuwabara.

The crew's on a quest for a second core ballast to complete the Quin Zaza Mark 2. Luckily, they've already got a lead on one--the original Quin Zaza, which went down years ago. Or did it? Locals claim they've seen the old draker vessel wandering the skies like a phantom. Mika and the others have fought all manner of dragons, but how will they fare against a haunted ship?
