Gin is a tall private eye with a dangerous side project crafting potent drugs for mobsters. He's also an inept swordsman whose most powerful tool is... bluffing.

Despite Gin's best efforts to eject this annoying (albeit talented) kid from his life, danger knocks on their door. They've got big cases to solve and bigger secrets to discover.
