"That is how we solve things here. If a tribe has a problem with the other, they send their best warriors, and the winner decides how things will be," The beast king declared. "If you want to stop all the tribes from joining the war and forgetting what you humans did to your honor, you will have to defeat all of them. Do you accept these terms?"

"You have the numerical disadvantage, so we will let you fight all of us one at a time," The beast king explained. "If one of us loses, the next can face the same tribe leader, but if all of you three lose against the same tribe leader, then we will do what we want. Even if you lose against one, the loser can face the others."

"Simple enough," Rain nodded.

Things weren't so simple enough, actually. Rain and the others would carry out the damage to the other fights, but so will be their adversaries. It was simple enough for him, who was planning to defeat everyone by himself.
