Notes:

Inspired by a wisecrack from u/FlameDragoon933 on Reddit. Original image is a screengrab from the Reign of the Seven Spellblades anime. Ophelia Salvadori warns protagonist Oliver Horn to "stay in the school building like a good student, especially for the next few months". Three episodes later she has an experiment go awry and is "consumed by the spell", and her chimeras start to rampage through the labyrinth and kidnap seventeen students.
