As the abomination smiled, swinging his fist at Jack's face, a rush of divine magic flooded from his side. His eyes barely moved, seeing Lydia jump on a table while students were still in class, she burst through the door and swung her sword, only the window's glass between her and the abomination, and he could feel that he had to run.

[Divine Cleaver] Lydia's swing destroyed the whole wall and the students were blasted back to the inner wall, gasping for air as they saw her fly away to the edge of the garden, pushing the abomination with her blade.

"What was that?!" A student cried.

"Don't move!" Jack shouted at them, "A monster infiltrated the school, wait for your teacher to come back."

"Jack?!" Those were his classmates, "What are you doing there? The light poles aren't a toilet, you know that?"

"Wait, is that armored girl the monster?" Another gasped.
