"I'd like to be a kitsune." You answer.
"All right then." The headmistress said. "Just take off your shoes and socks and I'll get ready to change you."
You take off your shoes and socks while the headmistress removes a book from the nearby bookshelf.
"Is that a spellbook?" You ask.
"Yes, you are very observant." She says. "I am actually skilled at different forms of magic." She turns it until she finds the right page and asks "Are you ready?"
You nod your head then she begins to cast the spell. You glow with a red aura as you can feel the changes happening. Fur begins to grow all over your body, white on your belly and the bottom of your face, brown on your hands and feet, and brown everywhere else. Paw pads form on your hands and feet and your nails grow and sharpen into claws. Your ears move to the top of your head and become fox ears. Your face pulls out, becoming a fox muzzle. You hear the sound of fabric ripping as several tails burst out of the back of your pants.
"Your transformation is complete." The headmistress says as she closes the book. You see a mirror nearby and get a look at your new body. "What do you think?" She asks.
"This is pretty cool." You answer, though to you 'pretty cool' was probably an understatement. Aside from the clothes you were still wearing, you looked completely like a kitsune. As you turned around to look at your tails, you found that your pants were still ripped in the back. "What about my pants?" You ask.
The headmistress answers. "We had more than a few clothing problems with some of the students, like werewolves tearing everything up transforming, or things getting burned by dragon fire. So, we had to hire a school tailor. She should be able to help you. She can also alter the rest of your pants to accompany your tails."
