Ayeka Masaki Jurai

Ayeka is the first princess of Jurai first born to Misaki and Azusa. Over 700 years ago, Ayeka was arranged to marry her half-brother, Yosho. However when Ryoko attacked Jurai, Yosho fled the planet to defeat the space pirate. Desperate to find him, Ayeka left Jurai two years later with Azaka and Kamidake to locate Yosho. She was put into suspended animation for 700 years until Yosho was found to be on Earth. Learning Ryoko was also on Earth, Ayeka grew anxious to capture her believing Ryoko was responsible for Yosho's disappearance. However, she is forced to live on Earth when Ryoko crash lands Ryu-oh into Earth. Ayeka still held her vows in trying to locate Yosho until she learned that Tenchi's grandfather, Katsuhito, was her half-brother. She also later learns that Ryoko didn't intentionally attack Jurai as she was under the influence of Kagato's mind control. Ayeka currently has her sights on Tenchi and constantly feuds with Ryoko competing for Tenchi's affection. However, she restrains herself from her affections upon hearing that her grandmother Seto arranged for Tenchi's marriage with Noike.

Ayeka is always being guarded by her two Jurai 'log' guardians, Azaka and Kamidake. However, Ayeka is actually much stronger as she has the power to generate smaller versions of the two. These versions can be used to immobilize enemies or as a protective barrier against any incoming attack. Ayeka generates the power with her mind meaning any type of strong force that she guards or attacks against can exhaust much of her energy at times.

When we first see Ayeka, she acts like a stereotypical princess in anime: spoiled, demanding, and can get frustrated if her orders are questioned. She has a strong hatred for Ryoko thinking she was responsible for the loss of Yosho and does show some hatred for Tenchi at first thinking that he was Ryoko's lover. However, Ayeka eventually shows some attachment to Tenchi when she learns that Tenchi has no romantic interest in Ryoko. During the conflict with Kagato, Ayeka learns that Ryoko wasn't actually responsible for the attack on Jurai. After Kagato's death, Ayeka is no longer the royal pain she had been before. She can now do almost any type of regular chore around the Masaki household on her own and doesn't show as much hatred towards Ryoko. Ayeka does respect Ryoko more but still dislikes her quick attempts for Tenchi's affection. She is very polite and proper all the time unless she's aggrivated by Ryoko. Ayeka is trying to start her relationship with Tenchi slowly, but Ryoko's interventions in this plan tend to get Ayeka quite frustrated. She is quite picky with discussing sexual affairs and is a light drinker on sake though there are times where she can drink too much (like in the onsen where she calls Ryoko an old lady while drunk). Ayeka proves her devotion to Earth and Tenchi by refusing to go back to Jurai from Azusa's orders.
