As a Classroom Exorcist your job is to track down and free the possessed student by the end of the school year. But the only way to do that is to engage in social challenges and make friends. But be careful, the demon is turning students into your rivals to suit it's own diabolical plans.
Each student has their own relationships, abilities and their own potential to be the demon's host. An easy assembly contraction combining the class roster with a relationship chart allows for deep but fluid play using any standard deck of Tarot Cards.
