I'm reading "Drops" as is one of my teenagers. We haven't gotten Vol. 3 yet and I just checked and found out that 4 will be available in about a month and 5 in September.
Thanks for the links. I'll check out more of that site.
There's a very interesting series that's a alternative history called "Ooku, the Inner Chambers". It considers the idea of what changes might have happened to Japan under the Tokugawa if a plague had struck down young males such that only 1 in 4 live to adulthood and that includes the upper classes. When there is no male heir to the shogun his only daughter is placed in the role with his male name in order to keep some order after recalling the decades of war leading up Tokugawa Ieyasu establishing order. This continues over many decades and the reversals that happen are well thought out. The incident of the 47 ronin is in one of the later volumes with some interesting twists.
The "Ooku" of the title was, in our history, the quarters of the shoguns' wives, concubines and their servants. In the manga the roles are reversed but there is the crucial point (which is shown in the society in general) of trying to get children no necessarily just pleasure.
This is not a manga for small children because of the complicated ideas as well as a few scenes of violence (that do pertain to the plot) and references to sex mostly with the idea of trying to have children but not always. But it is quite well done for older teens and adults. There's some very fine art work in places and some thoughtful considerations. There's even one of the regular visits by the "Hollander Kapitan" - the Dutch trading company leader who had to journey to Edo to pay respects which was part of the real Shogunate.
