The legendary ruler of the underworld, “King Yama,” is forced to bind himself to the [Good Karma System] to escape his enemies’ pursuit and cure a hidden illness. He must disguise himself as a woman and pose as “Auntie Liu,” the dorm supervisor at an art college, while accumulating good karma. And so, an all-purpose dorm auntie is born: she uses gang-negotiation tactics to settle dorm disputes, counter-surveillance methods to catch students sneaking in late, and the mindset of a financial criminal to help the student council manage its money. Not only must she spoil a group of wildly different “little tyrants,” she also has to discreetly eliminate the various assassins who infiltrate campus without exposing her identity.
