Magical Girl Academy

"What is the Magical Girl Academy?"

"It's an academy that trains witches."

"Trains witches?!"

"That's right. Didn't you know that magical girls are just witches who haven't grown up yet?"

"Ah, um... I can't say I didn't know that at all... So what do witches do?"

"Witches, of course, are the Demon King's women. So magical girls are the Demon King's fiancées."

"...And who is this Demon King?"

I straightened my collar and replied with a sincere expression:

"Me. I'm the headmaster of the Magical Girl Academy."
