Tenchi's older sister who resembles their deceased mother.
Tennyo is the first child born to Nobuyuki and Kiyone Masaki, being the older sister of Tenchi in the OVA continuity of Tenchi Muyo. Having a near exact resemblance to her mother, Tennyo would usually care for Tenchi in her place when he was younger. Despite her young appearance, Tennyo is actually 80 years old and like her grandfather Yosho, she takes on an older form so humans on Earth don't get suspicious of her physical appearance. She visits Tenchi and his extended family in episode 2 of the third OVA series to introduce the boy to his fiancee, Noike.
