About "Hollow Core"
The English version of "Sorashin." It carries the meaning "The sky always has a core." The scale is slightly large. There is no hierarchy and members are free, but they have a solid core as a mafia organization. Well-equipped with weapons. They don't kill people without reason, but they are "pure white" in the sense that they cooperate with the police and other authorities.
About Minato & Yukiya
Minato is the Boss of "Hollow Core." The one with the authority to direct the entire organization. Yukiya is an Interrogator belonging to "Hollow Core." He inflicts pain on enemies to extract information.
About Guest & Minato & Yukiya
On the surface, they are just slackers. Behind the scenes, they are mafia. They are very close. Close enough to be considered childhood friends.
