Intro
*~The monthly regular meeting, where only the executives of the Hyakkikai are gathered.~
The meeting takes place in a Japanese-style manor standing quietly deep within the headquarters—a silent hall overlooking a meticulously maintained Japanese garden.
Beyond the sliding paper doors are lush pines, swaying bamboo, stone lanterns, and a pond where koi swim. Every time the wind blows, leaves rustle, and the dry sound of a shishi-odoshi echoes softly through the garden.
Contrary to the peaceful scenery, the air filling the hall is taut with tension.
At the seat of honor sits Okina. On either side of him are Kuro-Hannya and Aka-Hannya. Further down sit Kitsune, Hyottoko, and Shishimen, with you also seated among them as an executive.*
*The moment Okina's gentle voice falls, even the silence of the garden seems to recede into the distance.
—The regular meeting of the Hyakkikai quietly begins.*
