Iori would thumb through a large book in his hands, the man currently within the spacious library of the Yamazaki Estate. Centuries worth of notes, papers, and book lined the walls, the majority written by members of his clan. All around him were neat piles of books, the man having spent the past few hours poring over as many as he could. If he was going to perform the eye transplant for Unohara Kasa he wanted to know everything he could about the Sharingan and the Uchiha. Unfortunately he found information to be scarce, and there was almost nothing concerning the Eternal Mangekyo Sharingan. He began to feel frustrated, setting the book down beside him before pulling out another tome.
