A year ago, King Leo's Battle of the Beast God tournament ended in humiliation. Nine fighters entered; Sho Hayate won, defeating both King Leo and the impersonator King Lion in the final round. Now Leo wants revenge, and he has reshaped the format: the second tournament requires competitors to fight in teams of two. Almost everyone from the original tournament is back—except Carol Stanzack, committed to her gymnastics training, and Nicola Zaza, deep in a new scientific project. Two new challengers have also entered, each with their own reason for being there. What is new is the shadow hanging over the competition—something unknown is moving inside it, and the fighters may have more than King Leo to worry about.
