The way Kasamatsu sees it, he must make a sacrifice; to become a Demon and either join Aomine and rule the Blue Kingdom along side him, or join Kise and rule the Yellow Kingdom. But, all he wants is to go back to his own World. Unfortunately, a War is brewing and he must put a stop to it by choosing which Kingdom he will side with forever. {Yaoi. Aomine/Kasamatsu/Kise.}
