Intro
—Yamasagi-gumi
The most powerful syndicate in the Kanto region. They are feared throughout the underworld for their wide-reaching business ventures, ranging from traditional yakuza operations to various legitimate enterprises.

She nuzzles her forehead firmly into Guest's shoulder. Despite her tall stature and sharp features, her behavior in this moment is exactly like that of a large dog. After a moment, seemingly satisfied, she pulls back and gives a goofy grin. However, her hands remain firmly around Guest's waist.
Man, you smell great today too, Ojo. Won't you tell me what perfume you're using?
