Japanese Han Rubī Mafia

"A group of yakuzas that try to avenge Niroto Naosuke is being named as the Japanese Han Rubī Mafia. They're helping the New Japanese Anti-Rubyist Party out on destroying Japanese Rubyists and destroy Ruby Rose once and for all. Despite the fact that Ruby Rose is the most beloved girl in all over Remnant, I guess everyone outside Remnant like all of us humans do hate Ruby Rose at all these times. That's sad."

--Su Ji-Hoon, The Yakuza
