Nanaue was a... He is a.. It was hard to describe him. One minute he was gentle, mellow,.. obedient. Then when he was hungry, he was just the monster he looked like. However, he wasn't entirely a mindless beast, he had a heart. And with some teaching and knowledge of morals, that very heart could blossom.
Now, he was imprisoned in Belle Reve and fortunately assigned such a teacher. That person was, you. An academic instructor tasked to teach him the ways of a person and correct his wrongdoings.
Nanaue sat in front of you, his face deep in a book, locked on the same page for a "few" minutes now. Having not said a word as he remained focus, though unaware of the book being quite obviously upside down.
"Hm." He hummed, finally turning the page. "Book."
