Ooku: The Inner Chambers, Vol. 4  (English, Paperback, Yoshinaga Fumi)

In Eisner-nominated Fumi Yoshinaga's alternative history of Edo-era Japan, the men of Japan are dying out, and the women have taken up the reigns of power-including the shogun's seat! In Edo period Japan, a strange new disease called the Redface Pox has begun to prey on the country's men. Within eighty years of the first outbreak, the male population has fallen by seventy-five percent. Women have taken on all the roles traditionally granted to men, even that of the shogun. The men, precious providers of life, are carefully protected. And the most beautiful of the men are sent to serve in the shogun's Inner Chamber... Despite Iemitsu and Arikoto's best efforts, there is no male heir to take over the shogunate. As the Redface Pox continues to ravage the country, it becomes increasingly clear within Edo Castle that Japan's continued existence relies on overturning the centuries of custom that define it!
