After seeing a picture of Naotora Kusunoki as a kid, the crown prince of the Kingdom of Urunei in Southeast Asia fell in love at first sight. The only problem is that Naotora is the son of a bureaucrat in the Japanese Ministry of Foreign Affairs. Eager to please the prince, Naotora's father forces him to cross-dress and fly to Urunei to get married to the prince as "Nao". Once in Urunei, he unintentionally captures the hearts of the populace who see Nao as the return of Putri Harimau, the Tiger Girl of legend who had a hand in the founding of Urunei with the Dragon Prince long ago. However, there are some in Urunei who are not so happy about Nao's arrival.
