"What is that?" Those words... those words rang in Constance's mind for what seemed to be forever, Agatha unraveled the mat black scroll with shiny white writing explaining miss hardbrooms whole life and they were about to experience it-

Miss hardbroom: WAIT! What if we battle? 1 vs 3? If you win you can do whatever if I win you stay away from This academy till the day you die and so forth!

Agatha: alright but you can't use magic!
The girls and teachers wondered how would miss hardbroom win without magic?
Miss hardbroom grinned and the only word she said was
"Bet..."

Amelia gathered all the girls to the left side and put a border so no spells could hit them and Agatha and Constance set ready to duel.
You could cut the tension with a knife.
Miss cackle said...

The handkerchief went down the battle has started, Miss hardbroom threw down her locket she always wore around her neck and a black smoke came out of it surrounding her.

Agatha: I SAID NO MAGIC

MISS HARDBROOM: IM NOT USING MAGIC JUST MY NATRAL ABILITIES!

Miss hardbroom's hair turned white and neon green and her eyes glowed red a metal rod appeared in her hands and a golden mask covering her face 2 sets of blazing red horns and wings also materialize on her, Agatha knew she had mad a mistake and that miss hardbroom was not a born witch but made a witch, it had hit Agatha that miss hardbroom was indeed a demon. It explains why she has no parents, and never has any photos of her family except her younger sister Hecate hardbroom.
