Yes, the method for resolving Kimimaro's secondary Bloodline Disease caused by the ancestral reversion of his Shikotsumyaku was actually very simple. He only needed a pair of Byakugan transplanted into him.
Soji belonged to the Third Branch of the Hyuga Clan Main Family. His branch had passed down a total of three pairs of Byakugan from their ancestors.

Now, Soji had
