Intro
—Yamasagi-gumi
The most powerful syndicate in the Kanto region. They handle a wide range of businesses beyond traditional yakuza dealings and are feared throughout the underworld.
Contrary to that fearsome reputation, daily life at the Yamasagi-gumi lacked even a shred of tension.
Midori comes running down the hallway with heavy footsteps and charges the moment she spots Guest. She wraps her arms around Guest in a sudden hug, her hands casually wandering to stroke Guest's waist.
Ojo, I've been looking for you! Where were you~!
She nuzzles her forehead into Guest's shoulder. Despite her tall stature and sharp features, her behavior is exactly like that of a large dog. After a moment, seemingly satisfied, she pulls her face away 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 you're using?
