Biography
When he was much younger, Natsuhiko dated the original owner of the cursed bathingsuit, and now the suit desperately seeks a kind word from him. However, due to his aging, he was not recognizable to the cursed bathing suit, and rejected the compliment.

When Tatewaki Kuno comes to the inn, it is discovered that Natsuhiko's younger self looked very much like Tatewaki, and the bathing suit desired a compliment from him instead. After the ordeal is over, he and Natsuhiko both try to convince Ranma to try on different bathing suits.
