The legendary emperor of the underground world, "King of Hell," was forced to bind himself to the "Good Karma System" in order to avoid being pursued by his enemies and cure hidden diseases. He had to disguise himself as "Aunt Liu", the dormitory aunt of the women's dormitory of the Art Academy, to accumulate good karma. Since then, a "universal aunt" who can use gang negotiation skills to mediate conflicts in the dormitory, use counter-detection methods to catch students who return late, and use financial crime thinking to help the student union manage money was born. Not only does he want to pamper a group of "little ancestors" with different personalities, but he also wants to clean up the various killers who have sneaked into the campus without revealing their identities.
