Wings of Fire: Awaken the King

A strange dragon appears in Pyrrhia with no memory of his past life. Captured by SkyWings, the stranger is forced to fight in bloody arena fights. The stranger gets in even more trouble when, on a chance encounter, he meets with the Dragonets of Destiny, who also have been captured, and unexpectedly finds himself aiding them in their escape. And then it gets EVEN worse when giant creatures from another world invade Pyrrhia, forcing memories to flood the dragon's mind and awake the Kaiju within. It's time to awaken the King of Kaiju.
