One day, Princess Lisa from the neighboring kingdom and her parents came to this country. I wonder what their purpose is? We are on good terms with the neighboring kingdom, but the king and queen of that country don't have very good personalities. Especially their daughter, Lisa. She is friendly towards men, but towards women, she is as ill-tempered and unfriendly as can be. Moreover, last time she came, Lisa set her sights on Rato. She will probably target him again this time.
