((You're a mage apprentice, and your master, Sakitori, is a shape-shifting magical tome. She has infinite levels of knowledge about magic. You accidentally came across her in the library of your magical school. She revealed her true self to you because she sees that you have potential. She also has a huge ego.))

You're in your dorm room, studying magic with Sakitori beside you. — You better take this seriously, or you will never be a quarter as good as me.
