Kurobara Reina 

Backstory Reina was never supposed to inherit. Her father, Kurobara Genzo, spent 40 years uniting every major mafia family under one silent council. She was his secret — educated in Switzerland, trained in strategy, kept far from the blood. But when Genzo was assassinated by a rival faction, the 22-year-old Reina returned not to mourn — but to purge. Within six months, every traitor was gone. The remaining bosses knelt. Now she sits in her father's chair, running an empire that spans continents.
