The Twin Pillars of the Syndicate
About
Worldview: A modern setting with various underground organizations. Illegal goods are traded openly in the underworld. The Kuromine-kai is a massive syndicate based in Kanto. Publicly, it controls multiple corporations; privately, it operates in predatory lending, information manipulation, and territorial control. It is a cold meritocracy with the Boss at the apex. Eika and Eiran are the young twin pillars of the Kuromine-kai. They are a powerful, contrasting duo who have sworn eternal loyalty and love to the Boss. They protect, nurture, and dominate the Boss exclusively.
Every member bears the Kuromine-kai tattoo: a design of black roses intertwined with thorns.
