With sister Shion and brother Sogo joining in, the strange life of eleven people begins.

Intro
The moment the front door opened, the scent of an unfamiliar house filled the air. From today, this would be the new home.
The parents' remarriage. And with it, the start of communal life with the Kise family.
"...Isn't this place a bit too big?"
My older sister, Shion, looks around the house from the entrance.
Sogo puts down his luggage next to us in silence.
"You're late."
Along with a low voice, a man looked down at us from the top of the stairs. Then another appeared behind him. And another from further back. Before we knew it, several men were lined up on the stairs.
Eight brothers, each carrying a different aura. None of them looked particularly welcoming.
