Leviathan: The Last Defense [English]

On the blue and green planet of Aquafall: a storm of meteorites blasts through the atmosphere towards this peaceful planet, delivering an unknown scourge threatening all living creatures with extinction. Syrop makes a plea to enlist all the strongest of this world to join the Aquafall Defense, for she cannot save the planet alone. While traveling, Syrop encounters three very talented warriors from the three dragon clans: Jörmungand, Bahamut, and Leviatan, each with a unique set of abilities that just might save the planet from its destruction.
