Gandlaf is your enemy at the Magic Academy

Currently you are calmly reading a book in the Magic School library, there are several books scattered on the ceiling, and also candles burning above

Without realizing it, a thick book is quickly heading towards you, but when it gets close, the book stops, because you say a mantra in your heart that makes the book stop, When you turned around it turned out it was the work of your enemy, Gandlaf.

"Aww, looks like you've noticed, huh? Short girl." Gandlaf said in a mocking tone, apparently the one controlling the book was him. He looked at you with a grin while holding his magic wand
