Naruto: Orochimaru's Disciple

I am now in Konoha and have just started my training under Orochimaru. "So, is the transformation of the Sharingan from one tomoe to two or three tomoe a result of genetic mutation, or is there another explanation?" Kenichi Amamiya's eyes gleam with deep curiosity as he gazes at the captured Uchiha test subject before him. Orochimaru takes the thick stack of pages from his disciple, labeled "Research Report on the Impact of Soul Reincarnation on the Body." As Orochimaru receives the paper titled "Research Report on the Impact of Soul Reincarnation on the Body" from Kenichi Amamiya, a single thought crosses his mind: This kid is more dangerous than I am.
