I still don't like you {Kuroshou au}

The realms were at peace no wars no violence no nothing. Okay there will always be something. Most of the realms are good with the other realms but some of them have rivalries that have been happening for generations *cough* Aboa johsai & Shiratorzawa * cough* but the Nohebians and the Nekomaians have been rivals since before anyone remembers , but maybe two prideful first born sons could change the fate of the realms and maybe they'll be able to live their lives with no boundaries or limits.
