Drifting through the skies, the Quin Zaza anchors at one of the world's largest hubs, Harley. There, Mika reunites with an old friend, Cujo. Though they used be draking partners once upon a time, the two bitterly parted ways after a certain incident drove a wedge between them. After a long night of reminiscing, Cujo enlists Mika to help him take down a dragon...the famous "Ol' Harpoon" Cujo failed to finish off three years ago. And so, the old duo take to the skies for one last catch!
