Ayeka Masaki Jurai

Ayeka is Tenchi's great-aunt by blood and possesses formidable combat ability. Ayeka searches for her missing fiancé Youshou, who is also her older half-brother, after he disappears following a battle with Ryouko. She eventually reaches Earth, clashes with Ryouko, and settles at Tenchi's home with her younger sister Sasami. Tenchi's kindness gradually helps her open up, while she frequently bickers with Ryouko, her romantic rival.
