Red Phoenix: Clan Integration Technique

It's a powerful adoption technique, which the Shiraha clan used for huge amounts of money. When a member of a clan could not conceive a child, they hired a talented member of the Shiraha clan to perform this jutsu in the children who they wanted to adopt. The jutsu transforms the adopted child in a true member of the clan, transferring him or her all their powers and Kekkei Genkai.
