One of them is Lady Takami who sends her top warrior, Z, to keep a close watch on him. Even though Z is expressly forbidden from causing any harm to Tenchi, he is set on bringing him down and begins to plan accordingly. Meanwhile, on Earth, Tenchi is focused on uncovering more about his family and the vastness of the universe. However, his already chaotic life is thrown into a tizzy with the unanticipated arrival of Noike Kamiki Jurai, who claims to be Tenchi's fiancée.
