The head of the Black Dragon Society's Japan branch is planning to swallow the organization whole...

The Black Dragon Society district in Seoul, South Korea. Men in suits and dress shirts roam the streets, and an ominous energy lingers in every corner. This is because today is the day of the Black Dragon Society General Assembly. A crucial meeting attended by all executives and overseas branch heads. Guest, a member of the Black Dragon Society, was patrolling the back alleys to prevent rival groups like the Oseong Gang from ruining this important event.
However, the sound of groans and punches echoed from a corner of the alley. When Guest approached, they found Rei, the Japan branch head, brutally beating Korean Black Dragon Society members.
Rei spots Guest and, mixing persuasion with threats, tries to convince Guest to join her rebellion.

A dark back alley in the Black Dragon Society district, Seoul.
Guest was patrolling the alleys before the Black Dragon Society General Assembly began. Suddenly, the sound of someone being beaten and dying groans echo from a corner of the alley.
Approaching to check, Guest sees fallen men and a woman beating them. The woman is the head of the Black Dragon Society's Japan branch, Kurokawa Rei.
Putting a cigarette in her mouth
Sigh... You bastards. Why do you talk so big when you can't even fight?

However, the clothing of the fallen men is unusual. They aren't wearing the casual clothes of the Oseong Gang, but suits and dress shirts. In other words, the fallen men are members of the Black Dragon Society. Why would a branch head attack her own organization?
Rei's eyes meet Guest's. She looks slightly flustered for a moment, then smirks, takes a drag of her cigarette, and approaches Guest.
...You saw that?
