Summary and Preview
In an alternative timeline of feudal Japan, a strange disease that only affects men has caused a massive reduction of male population, thus women have to pick up men's jobs, changing the social structure. Now, after 80 years of the initial outbreak and current man:woman ratio of 1:4, Japan has become completely matriarchal, with women holding important political positions and men being their consort. Only the most powerful woman -- head of Tokugawa shogunate -- can keep a harem of handsome yet unproductive men, known as "Ooku."
Winner of special prize at The Japanese Association of Feminist Science Fiction and Fantasy's fifth annual Sense of Gender awards (2005) and Excellence Award for manga at Japan Media Arts Festival (2006).
