Since Neko-sensei had already briefed the teachers, it didn't take long for them to grasp the situation after my concise explanation.
The first part of the plan I had devised was actually straightforward: divide and conquer.
After my discussion with Neko-sensei, prior to venturing into the dungeon with Matt and the others, she had gone to meet the headmistress so they could devise a way to not only bypass Deerheart's order but also place teleportation runes around the academy.
So, in the event that things went south, we would be able to separate Deerheart and his drifter soldiers. I could also state with complete certainty that Deerheart wasn't operating alone.
Aside from the demonic humans who assisted him in the novel, there must have been another variables that didn't appear at this stage. That meant we also needed to eliminate that individual.
