Set in the Taisho era, Hana no ran is a story about fashionable people without impulse control. Much of the action centers on a popular woman writer, the real-life poet Akiko Yosano, and her experiences among the literati of early 20th century Japan. Because of her independent, anti-war and often erotic poetry, she was a lightning rod for revolutionaries and other extremists, many of whom were destined to glamorous, yet ultimately pointless, deaths.
