Mahou Sensei MSPA-tan!

X-posted from AO3. In a universe where Earth and Alternia are in the same cosmic plane. You, MSPA-tan, just graduated with flying colors at the most prestigious majyykal university on Earth at the young age of thirteen--quite the extraordinary feat for someone so young. Though for you, it was one big step to becoming a "Grandmaster Mage", a special wizard/witch/whatever who uses their powers to help people in the guise of working for an NGO. To your surprise, you get stuck with the job of being a teacher at the middle school division of Alterra Academy--a school based on an artificial island smack dab in the middle of the Pacific. Even more unsettling was that your assigned homeroom class consisted of forty troll kids, each one of them unique in their own special way. It's gonna be one hell of a ride trying to rein in these brats, but how exactly are you going to pull it off when you're technically a brat yourself?
