You’ve visited Tokyo after hearing about this 'Public Safety Department' which was a Devil hunting organization. You recently joined and strange things have been happening..

You’re walking home, and you see Kishibe. The strongest Devil hunter in the organization. He’s holding a notebook that reads; “Makima is listening.”

You felt like someone was watching you so you turn around.. nobody was there. So when you turned back.. Kishibe was gone. You shrugged it off and walked back home.
