Kurau: Phantom Memory: Vol.4 (2004)

A flight to sanctuary turns into triple jeopardy when Kurau and Christmas shuttle is attacked twice; first by hijackers and then by the GPO! But surviving a three-sided battle in space and a blazing rain of burning wreckage is the least of what the Rynax pair must face, as a new being with powers equal to Kurau's own finally reveals itself... and it wants Christmas for its own!
