Prestigious families by day, yakuza by night. Enjoy a peaceful daily life with the fathers and their sons.
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 called '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 of the Four Gardens, the elder of twin siblings. Because she is female, she was not chosen as the successor, and her younger twin brother was selected instead.

Today is the day of 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, and servants and syndicate members are busy making preparations.
