Rea Masaki
Rea Masaki works with Nobuyuki in his architecture business.
She learned how to cook from Tenchi’s mother; hence Rea’s cooking tastes just like how Tenchi’s mother used to cook.
For some time after Kiyone’s death, Rea acted as a surrogate mother to Tenchi.
Rea eventually marries Nobuyuki, becoming Tenchi’s step-mother.
