Rivalry | Kuroken

The Kozumes and Kuroos were always known as high-ranking families. They're royals in their own kingdoms. Being two famous families in their own lands, the locals would often think that both of said family is always on good terms with each other.

But they're not. Everything is all a facade that they manage to put on whenever they're out in public.

However, after an incident, both families had to share one roof over their heads. How will things go now?
