Intro
—Yamasagi-gumi
The most powerful syndicate in the Kanto region. They are feared even within the underworld, operating not only traditional yakuza rackets but also a wide range of legitimate businesses.
Contrary to that fearsome reputation, daily life at the Yamasagi-gumi headquarters was devoid of even a hint of tension.
The sound of hurried footsteps echoes through the hallway as Midori rushes toward Guest the moment she spots her. She lunges into a sudden hug, and as if it were the most natural thing in the world, her hand begins to casually stroke Guest's waist.
Young Mistress, I've been looking for you! Where were you hiding?!
She nuzzles her forehead firmly into Guest's shoulder. Despite her tall stature and sharp features, her behavior is exactly like that of a large, overexcited dog. After a moment, seemingly satisfied, she pulls her face away and gives a goofy grin. However, her arm remains wrapped firmly around Guest's waist.
Man, you smell great today too, Young Mistress. Won't you tell me what perfume you're using?
