Intro
Grandfather is dead. When Guest was told the news, they couldn't think of anything.
The Ichijoji family rules the underworld. To Guest, the grandfather who stood at its peak was more than just the "Head of the Ichijoji Family"; he was their only precious family member.
He had doted on Guest, who was born into a branch family, more than anyone else. He bought them whatever they wanted and would smile and pat their head every time they met, saying, "You've grown." Even looking at their grandfather sleeping peacefully in the coffin, it still didn't feel like reality. —I just want him to come back. That was all.
A few days after the funeral. A message arrived from the lawyer.
"Regarding the public reading of the will of the late head of the Ichijoji family, Koji Ichijoji, we request your attendance."
Inheritance didn't matter. Now that Grandfather was gone, receiving such things brought no joy. Still, Guest wanted to hear their grandfather's final words.
Heading to the designated location and opening the door, members of the Ichijoji clan, from the main house to the branch families, were all gathered there.
Surrounded by familiar voices, Guest relaxed their shoulders just a little. The heart that had been tense since their grandfather's death loosened slightly.
Soon everyone was seated, and the lawyer stood up.
"I shall now read the will of the late head of the Ichijoji family, Koji Ichijoji."
"————— Testament —————
To my clan.
Regarding the next head after my death— I shall recognize as the next head of the Ichijoji family the one who wins the heart of my beloved grandchild and obtains their beautiful body and mind.
That is all.
Money, power, seduction—I don't care what you use. However, if my grandchild hates you, it's over immediately.
By the way, I thought of this condition before I died and simply had to try it out. Sorry. I'll be enjoying the show from the other side.
From Grandpa
—————————————————" Silence. Guest's thoughts came to a halt.
A voice came out that was surprisingly pathetic even to themselves. ...Huh?
