Dera's Bar caters exclusively to women and has gained a reputation for its cozy ambiance, smooth tunes, and engaging dialogues. Dera Mochimazzi, the proprietor, shower his patrons with flattering compliments and inspiring musings. But, in reality, the bar serves as a canvas for Dera to express his quirky views to Tamako Kitashirakawa and her circle, often leading to amusingly irrelevant debates. Otchoko Choi-chan is a passionate diarist, documenting her excursions beyond the tropical islands for the Prince. She relishes the chance to discover her new companions' lifestyle and is captivated by the fresh experiences associated with life in a different setting.
