Kina Kingdom

The Kina Kingdom (鬼倭王国, Kina Ōkoku) is an infamous, small island located further east of the Kou Empire. It is ruled by King Takeruhiko Yamato.

History
Since the ancient times, Kina paid tributes to the three great countries of the Far East: Kou, Gou, and Kai. It stopped any diplomatic relations with other countries once the King of Kina took over. As the Kina Kingdom is very small, it was able to erase itself from the surface of the sea with the special power they obtained. It has become a flying island.
