Byakkotai

is a group consisting of surviving Otsutsuki Clan members of the Family Branch. Over the past millenium, they have hunted down members of various clans and even payed off other clans to see that descendants of the Branch Family of the Ōtsutsuki Clan are killed and utterly wiped out.

Over the many centuries, they have become modern and have slayed many remaining Ōtsutsuki Clan members as well as members of their descendants. They have personally wiped out the Senju clan and had the Uzumaki and Kaguya Clan clans killed off. They helped dwendle the numbers of the Uchiha down until they made their home within Konohagakure. They couldn't touch the Hyūga Clan due to them being so heavily guarded at the time.
