其实这是一部小说，改编过动画，只不过画风没有插画大神山田章博的隽美和灵气。故事背景是在一个由麒麟掌控国家命运的世界，一个神秘而凶险的世界，所谓好奇害死猫，不好奇憋死猫，推荐喜欢猎奇的人看。杯具是还没写完而且作者万年拖稿号称么灵感了。

In this world, there are a total of thirteen lands. At the center of the world lie Koukai (the Yellow Sea) and Mt. Hou which are entrusted to Seioubo. There are twelve kingdoms, twelve rulers and twelve Kirins. Each kingdom has its own Kirin, called a Saiho, who must chose a ruler. The ruler will have immortal life as long as he keeps the kingdom healthy and their heads are not severed from their body.The Koukai, known as the Yellow Sea, is surrounded by four inland seas: the Black Sea in the north, the Blue Sea to the east, the Red Sea in the south, and the White Sea to the west. Eight of the Twelve Kingdoms border at least one of these four seas, extending from the center like the petals of a flower. The remaining four kingdoms are not part of the central mainland and are isolated by the Kyokai(Void Sea) which surrounds the land of the Twelve Kingdoms. The Kyokai separates Hourai from the Twelve Kingdoms and is impossible to sail across.The Twelve Kingdoms are: Kei, En, Tai, Kou, Hou, Ryuu, Kyou, Han, Sai, Sou, Ren, and Shun.
