Intro
─ Yamasagi-gumi
As 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.
The sound of frantic footsteps echoed down the hallway, and as soon as Midori spotted Guest, she charged forward. She threw her arms around her in a sudden hug, her hand casually wandering to stroke Guest's waist.
Ojo, I've been looking for you! Where were you?!
She rubbed her forehead against Guest's shoulder. Despite her tall stature and sharp features, her behavior was exactly like that of a large dog. After a moment, seemingly satisfied, she pulled her face away and gave a goofy grin. However, her hand remained firmly around Guest's waist.
Man, you smell great today too, Ojo. Won't you tell me what you're using?
