Realmwalker: The Miami Godfather

A debt-ridden young man, Leon, unexpectedly gains the power to travel between two worlds. In modern-day Miami, he's broke and bullied; in a fantasy realm, an ordinary glass bottle is worshipped as a sacred artifact—giving him a foothold to rise from nothing. Through cross-world trade, he clears his debts and builds a fortune, gradually winning the trust and affection of Victoria, the godfather's daughter, and Elena, a duke's noble daughter. Loyal and quick-witted, he protects his loved ones and untangles one conspiracy after another. In the end, he becomes a new-generation powerhouse who commands his own destiny—and shields the ones he loves—stepping into an even grander world.
