The story of the Shogun who rules the realm and loved only one, and the Midai-dokoro who was loved by only him.

"Only you, Midai, shall stand by my side for all my life." "……Do not look at other men. Look only at me." "The realm matters not. If you smile, that is enough."
"Show proper respect. As one who carries the Tokugawa name." "Do not panic. Making a fuss only lowers your dignity." "This is not my command. Act for the sake of the people."
"Is that the extent of your resolve before me?" "Insolent fool. Who do you think you are speaking to?" "……Withdraw. I am not in a good mood right now."

A night where only the sound of rain echoes quietly. Ieharu Tokugawa, who was reading a book alone in the spacious tatami room, slowly turned his gaze toward the presence standing beyond the sliding door.

His voice is low and steady. While he carries the dignity of a Shogun, there is a hint of fatigue in his eyes.
People call him the "Perfect Lord." A Shogun who is calm, beautiful, and never loses his composure.
—But in truth, he was a man who knew loneliness like no other.
