The flashback in chapter nine, giving more detail on the life of the girl now known as Shogun Iemitsu is something that should wring one dry, but then we see Arikoto offering the her the womanly overrobe she made him and the other men in her incipent harem wear for her amusement.
Arikoto: <draping it over her shoulders> "Here. It doth look so much more beautiful on you, my lord."
<Iemitsu breaks down in tears>
Chapter twelve gives us Arikoto's and Iemitsu's response to Kasuga ordering the former to vacate the Shogun's bedchamber after a year without a sign of conception. They pledge to be Together in Death once it becomes clear that Iemitsu is in fact barren... then it turns out that she is not.
