Minaho Masaki

The oldest daughter of Airi and Yosho Masaki (her younger sister Kiyone, long since dead), Minaho Masaki works closely with Seto Kamiki Jurai.

Minaho is a very efficient worker, and often keeps her lady informed about affairs within the Jurai empire... as well helping Seto to mettle in the lives with her nephew Tenchi and his friend Seina Yamada, although she has not inherited the playful, almost jokester attitude of her mother.
