Hogwarts’ Beloved Is Frantically Testing the Limits of Expulsion

System Mission 1: Pet Professor McGonagall's cat head during Transfiguration class

System Mission 2: Use Potter family shampoo to wash Professor Snape's hair during Potions class

System Mission 3: Go all out on the back of Quirrell's head during Defense Against the Dark Arts class

The professors: "Expel him!"

Kailan felt wronged. It was the System! The System made him do it!
