Once upon a time, there is a well-known restaurant in Resonance Town named, Honey Cave. The owner is a widow named CHI; however, she is not an ordinary housewife. Because she is a former renowned thief with excellent stance of martial art. But in spite of this, she is also a generous and open-minded person. CHI has triplets, two boys, NIN and YUI and a daughter, YEK. NIN used to be working as a government official in the capital, but he has offended the princess and has been demoted. He opposes the inconsiderable decision of princess, who spends a huge sum of money and a great force of labor on the construction of lake; therefore, he makes joke on the princess through poem.
