Characters Dragon King Nation The Dragon King Nation is the largest and most prosperous empire in the other world, and a member of the Alliance of Four Nations. Its primary populace consists of dragons, who have the inherent ability to shapeshift into human form; but because of their aura, they tend to repel most normal animals, which renders them unable to keep pets. Dragon blood can also be used as an ingredient for powerful healing agents, but is deadly poisonous if not properly processed. While ruled by dragons, the nation's reign is benign and cosmopolitan, with everyone enjoying equal rights regardless of their ancestry; hence the realm is inhabited by a mixed balance of humans and beast folk. The title of the Dragon King is not hereditary; it is won by challenging and defeating the incumbent ruler in a public duel held every thirty years. Because of the dragons' inherent strength and toughness, it is also the militarily strongest realm.

After Ruri's secret comes out, Jade begins wooing her to become his queen, which is made rather difficult because of Ruri's belief that he might like her more as a cat than as a human.
