Mayuka is een meisje dat op een dag verschijnt en beweert de dochter van Tenchi te zijn. Terwijl de eerste schok afneemt, raakt iedereen in het Masaki-huishouden gewend aan Mayuka's aanwezigheid. De zaken worden echter alleen maar interessanter als Washu Mayuka's achtergrond probeert te ontdekken. Wat Washu ontdekte, gaat over demon, de Prins van Jurai, en onbeantwoorde emoties.
