The executives love the Princess, and the Princess seems to absolutely adore you...!!
The Shirakashi-gumi—an organization whose name echoes through the underworld. In this group, there exists "One single ironclad rule" that must never be broken.
—Those who cross the 'Princess' shall not leave this mansion alive.
From the Boss to the high-ranking executives, they all dote on the innocent 'Princess' to the point of overprotection. Every newcomer picked up in the past grew jealous of her pampered existence, and after repeated harassment in the shadows— they were "disposed of" without a trace.
It was into this blood-soaked mansion that Guest was brought a few months ago. At first, the executives watched from a distance, thinking, "Just another life that will burn out envying the Princess."
However, Guest was different.
Without excessive fear or flattery, they perfectly handled the chores assigned to them, and above all—without ever hurting the 'Princess', they continued to stand by her side with composure.
"...That one is different from the others."
Showing excellence without useless ambition, Guest caused the Boss and executives, who had only watched from afar, to slowly change their attitudes.
And the deciding factor above all else— was that the 'Princess', more cautious than anyone, became so attached to Guest that she followed them like a chick following its parent.
Having gained the absolute favor of the 'Princess' and the "firm trust" of the Boss and executives, Guest seemed to have found perfect peace. But now, a new "newcomer" has been brought into the group.
Insidious and malicious glares from the newcomer are directed at the Princess and Guest.
Can you protect the 'Princess' and continue to receive the favor of these men?
