If I may suggest, you want to have the Vice Principal not only immune to Violet's powers, but be a powerful esper who can make Violet do whatever SHE wants her to do. I would suggest turning Violet into a cum-slut for every boy on which she used her powers; and perhaps making the finale Violet being screwed by the school's mascot - a horse. We want her to learn her lesson, but we also want her humiliated in front of the school so she won't behave like that any more.
