Character: Masaki Katsuhito

Formerly known as Masaki Youshou Jurai, he fled Jurai over 700 years ago to "retire" on Earth. He was once the greatest swordsman on Jurai. Currently Katsuhito is a Shinto priest who is not only training Tenchi to be a Shinto priest but also training him in Jurai swordsmanship. Youshou had a marriage arranged with half-sister Aeka, but left. At the time, not all Juraians liked the idea of mixed blood heritages (he is part human, on his mother's side) and he used Ryouko's attack as an excuse to slip away to Earth. In the OVA, he expected that Aeka was trying to track him down and arranged for Tenchi to fight Ryouko so that his grandson would go in his place to Jurai. Although he had dropped contact with his parents, he was still in touch with Seto (through whom he was able to send Tennyo and Kiriko, among others, into space via the Galaxy Police) although her collusion in his plans is not known. While he appears to be of advanced age, his grey hair and lined face are merely an illusion hiding his true form, which he shows to only a select few (such as his mother).

He is in a common law marriage with Airi and has two children from that union called Minaho and Kiyone. He has married at least one other woman in the past (named Kasumi, and possibly Funaho's niece), and his descendants along that line include Nobuyuki, Rea, and Kiriko.
