Unohana Clan

The Unohana Clan was founded thousands of years ago on the Soul Society by a man whose name is still unknown, there are no written records of him anywhere within the Seireitei but it has been orally passed down throughout the generations that Retsu Unohana was a direct descendant of him and because there were no records of the founder she became the first official founder and head of clan after ordering the construction of the manor that still serves as the residence to the main family and other descendants.
