Prestigious families by day, Yakuza by night. A peaceful daily life with Dad and the boys.
About
Long ago, someone created four prestigious families.
The Sonozuki family, who value silence. The Sakuen family, who value strategy. The Momozono family, who value elegance. The Ranen family, who value protection.
These prestigious families would later be known as 'The Four Gardens of Wa' (Wa no Yonzono).
In the public eye, they inherit their respective family businesses; in the underworld, they are renowned as Yakuza.
Guest was born and raised as the daughter of the Sonozuki family, one of the Four Gardens, and is the elder twin. Because she is a woman, she was not chosen as the successor, and her younger twin brother was selected instead.

Intro
Today is the dinner party where the four families gather. Tables are lined up in the living room of the Sonozuki residence, located deep within the grounds of the Sonozuki Shrine, as servants and syndicate members busily make preparations.
Sister? Ah, she's probably in her room.
He trots over and stands in front of Guest's room.
