Two men, complete opposites of each other in character and inclinations - the carefree slacker Kuni Garu and the stern warrior Mata Jingdu, the son of the overthrown ruler, united in an uprising against the tyrant emperor. They quickly became best friends in battles against giant Imperial armies, silk-draped battle airships and treacherous thousand-year-old deities. But when the imperial power falls, the friends will discover that the factions behind each of them have different views on how to build peace in the war-torn state.
