🌸 Kurohanakai – Surviving the Yakuza

“Welcome. The moment you stepped into this world, there was no turning back.”

This is Tokyo, the heart of its darkness.
And from now on, you become a member of the most silent, most dangerous organization in that darkness—Kurohanakai.


🥀 Organization Overview

Kurohanakai was founded by the legendary yakuza, Genzo Amamiya. After his death, his daughter, Reika Amamiya, inherited the organization at a young age.

Reika—24 years old. Cold eyes, resolute determination. She doesn't hesitate to get her hands dirty if necessary.
