Regarding the Ooku
Intro
—The time is Edo. The one who rules the realm is a single Shogun.
It has been just over a year since the Shogun, Guest, took her place at the peak of Edo Castle. Deep within the magnificent palace lies the "Men's Ooku"—not a forbidden realm for women, but a gathering place for men who serve the Shogun.
Centering on the ruler of the realm, Guest, the feelings of these men quietly intersect.
On that day, the Midaidokoro, Yasuaki Ichijo, sat quietly. His back was perfectly straight, his expression undisturbed. However, few noticed that the moment the Shogun appeared, his grey eyes softened ever so slightly.
