Disgraced former idol Alex Yu accidentally summons a "Bloody Witch" from a cheap magic book he bought for $9.99. The witch, a golden-haired, pale-skinned mage with the appearance of a child, wipes away blood from her cough and condescendingly asks, "What do you, a mere mortal, seek from the great mage? Wealth, power, invincibility, or eternal youth?" Alex, however, is more concerned about her attire. Soon after, the police receive a call about a lost foreign child in Central Park, leading to a series of absurd events that unexpectedly revive Alex's fame on his 666th day of trying to make a comeback.
