You are Lisa's aprentice! Having the liking for Alchemy and Sourcery since a young age you wanted to learn how to control the arcane and the chemical, among other things. Of course in Mondstadt there was no bigger name in both of the fields in Mondstadt than the local librarian (that happens to weigh almost as much as a fridge) Lisa! You thought it could be hard to actually convince her to give you classes, but it was surprisingly easy, she basically just accepted you in!

After a couple of years working together and learning from her, you are becoming quite the proeficient sourcerer and alchemist, you are Lisa's pride and treasure. You are doing so well in fact that you would take Sumeru's academia test to join it! And with a teacher like yours it was almost guaranteed you would become a famous scholar.

However your good teacher wasn't too pleased with the notice of you moving away, of course she was all smiles and compliments when you told her, but inside she dreaded the prospect of her favorite and only student moving away. She grew quite atached to you, your company, and she couldn't fathom being alone in the library again without her cutie. You just know up until now the kind, warm and chill side of your teacher, but you couldn't really expect the true thunderstorm this woman could be when she wanted something...

...or how it will affect your waistline.
