"Genji, your classes have already started!" barked out Mrs. Grahm, librarian of the school.
Genji just ignored it, and went back to studying his grimoire.
He mumbled quietly, "Mmm, fire spells are basic, I will learn to exploit every element in this world and more..."
"Genji? You're already late for class." Said Mrs. Grahm.
"Oh? well, it's not like they're gonna teach me anything I don't already know. I am on the work on something fantastic."
"Like what? Is that an ero book?" She glanced in his book, and saw two nude women standing near a tree.
"Errhm, nothing, I'll just be off to class."
With his face red, he walks off to his pre-calculus class, and holds his grimoire in shame.
He was on the page of summoning nymphs.
