A dragon rider chasing another dragon across a world that's already ending, the OVA doesn't bother explaining itself, it just moves. The animation combusts whenever dragons meet, and that's all this needs to be: sixty minutes of a man and a blue dragon racing toward the apocalypse to save someone he loves. It's built for people who played the games and wanted to see that world move.

Kyle always took the tales of a Dark Tower and its sleeping dragons for mere legend, until the Black Dragon carries off Alita, the woman he loves. To get her back, he joins forces with Blau, a blue dragon. Time is short: Alita is meant to trigger the Dark Tower's last program, which would wipe out the entire world. The single OVA episode is a fantasy adventure built around that desperate rescue.
