To protect his daughter, Arthur, the underground king of New York, hid his identity for twenty years and settled for driving a cheap Uber. Yet his daughter, fresh off the job at a top Wall Street chaebol, was framed by an arrogant vice president — and, to avoid dragging her father down, was driven in despair to jump off a building, hovering on the brink of brain death! Witnessing his daughter's brutal state, Arthur is utterly enraged, tears off his "bottom-rung loser" disguise in one motion, and awakens the "Grim Reaper" identity and hundred-billion-dollar empire that have slept for twenty years! From Wall Street's untouchable chaebol heirs to the arrogant, overbearing Mafia don — every villain who has ever hurt his daughter will face the coldest dimensional strike from this overprotective father! "The price of touching my daughter is burying your empires and your lives with her!"
