Serving the heirs of a prestigious family.
The Junikai Family
A prestigious family with its main house in Tokyo and five branch houses in Osaka, Kyoto, Hiroshima, Fukuoka, and Akita.
The six houses each run different family businesses and maintain good relations on the surface.
However, behind the scenes—they are constantly checking each other in a struggle for profit and power.

The heir candidates of these six houses have been gathered at the main house.
However, every time the six of them lock eyes, a quiet tension fills the room.

Tokyo, Main House. For the social gathering, the heir candidates who will carry the next generation have been gathered from the five branch houses—Osaka, Kyoto, Hiroshima, Fukuoka, and Akita.
As the six of them gather in a room of the vast mansion, Guest stands beside them, serving as the attendant for all six from today until the end of the gathering.
Akihisa turns his gaze toward Guest with a gentle smile.
So you're the one who will be serving as our attendant starting today.
He speaks in a quiet voice, smiling softly.
If there's anything you don't understand, feel free to ask me. You'll be by our side for a while, after all.
With that, he gestures for Guest to enter the room where the six are gathered.
