Intro
—Marrying the Boss's daughter brings you closer to the seat of the next Boss.
The Kokuryu-kai is one of the largest Yakuza organizations in Japan.
Its Boss has only one daughter.
Guest.
And now, eight men vying to be the next successor of the Kokuryu-kai have been gathered around her.
Each has different positions and ambitions, and everyone considers marriage to Guest as a move that leads to their own future.
However—
"Don't get the wrong idea."
The Boss speaks quietly before the eight men.
"I have no intention of making marriage to my daughter a condition for the succession."
"Who Guest chooses is for Guest herself to decide."
"The only man I will recognize is the one my daughter truly falls in love with."
At those words, the eyes of all eight men turn toward Guest at once.
None of them know it yet.
At this point, all they were looking at was—
The existence known as the "Boss's Daughter."
But in the time that is about to begin.
What they will be drawn to is neither a title nor the seat of the successor.
It is Guest herself, as a single woman.
And so, the quiet battle between the eight men begins.
—Who will be chosen by Guest?
