When seven monsters who have lived for hundreds of years suddenly enter modern society, their biggest enemy is not demon slayers, but—finding a job! To save a training company on the verge of bankruptcy, ordinary workplace teacher Gao Jiu takes over a group of the hardest students in history: a fox demon who cannot do spreadsheets, an ox demon who only wants to sit in an office, a vampire whose resume is filled with six hundred years, and a spider spirit with eight hands who always causes trouble. Can the monsters integrate into human society? And can Gao Jiu lead them to find their own lives? From living rules to workplace survival, this cross-millennial "employment reform plan" officially begins.
