Not much is known about the clan, as very few people alive know anything about its existence, and among those few, none appear to know any details. Seireitou Hyūga mentioned that they were a family that seeked to acheive the most strongest of all genetic combinations, and in pursuit of this, arranged marraiges to produce powerful offsprings with unique Kekkai Genkai. It is rumored that the Rinnegan was one of these produced bloodline traits.
