Toneri was blind before he took Hanabi's eyes. The Otsutsuki Clan has been sacrificing and sealing their eyes into an altar in order to accumulate power for a thousand years. That power is called the Tenseigan (Reincarnation Eye) and represents the stored up ocular power of some 40 generations of Otsutsuki Clan members.

Ah nice. So "bred out" as in bloodline being mixed or too many generations from Hamura to inherit it? Wish we had more information about Hamura's side of the family. Im wondering how did his side split into the different clans and if the Hyuga and Otsutsuki were possibly one clan, only because they possess the same dojutsu which is usually inherited by the same clan and bloodline as I've seen it. My head hurts from all the possible plot twist
