The story starts briefly in Jiang’s eyes. Jiang, a Skylian Warrior, plans a ceremony for the new warriors, or just simply tells stories through his and his member’s music. An unfortunate event happened- a demon appeared in the sky to destroy everything and everyone in Skylia. What is this demon?

A land below Skylia, a former pirate, Hai Bo and crew set sail to do what Leviathan, his mother, requested. While sailing, he and his crew see an explosion in the sky. Is it from the same demon? If so, how can they stop this demon?
