Recalling What's to come?

After finally getting her room to herself, Lillian sat at her desk with an intense focus look on her face.

Looking down at a particular notebook with a pen in hand, she began jotting down the events that would happen.

First, she had to remember about a certain bin she had been pouring water inside the entire time.

Once every month leading up to this point, on a random day, a mysterious individual would drop in a cardboard box. Lillian knew that the individual was a student here at the academy.

Well...

She says student, but she wasn't sure about that. In the game, the student was a living puppet that was being mind-controlled.

The person who mind-controlled them was none other than the leading attacker in the invasion to come.

One of the 5 Priests of the Cult of Jesters. He was the weakest but the most impulsive and willing to not follow the orders of his superiors, which were other priests who were much stronger than him.
