Katsuhito Masaki (柾木 勝仁, Masaki Katsuhito), Tenchi's grandfather (on his mother's side). In the OVA, Katsuhito Masaki, also known as Yosho (Yōshō), 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 be a Shinto priest but also training him in Jurai swordsmanship. Yosho had a marriage arranged with Ayeka, but left. Not all Juraians liked the idea of mixed blood heritages (he is part Earthling) and he used Ryoko's attack as an excuse to slip away to Earth. In the OVA, he expected that Ayeka was trying to track him down and arranged for Tenchi to fight Ryoko so that his grandson would go in his place to Jurai. In the first TV series he is still known as Yosho and is related to Jurai's royal family and is the greatest swordsman who has ever lived, but is not a close relative to Ayeka or Sasami. In the 'Tench Universe' continuity, Ayeka is of a distant branch family, while Yosho/Tenchi are of the main line. This makes Tenchi the direct heir to the throne of Jurai.
