Fūka Masaki holds position as one of Seto Kamiki Jurai's Ladies in Waiting, working alongside Mizune Masaki and Otoka Masaki under the direct supervision of Minaho Misaki. She operates primarily as a combat specialist, displaying exceptional skill and serious dedication as a bodyguard during official duties. Off duty, her demeanor undergoes a significant shift, revealing a relaxed and playful attitude where she frequently engages in humorous behavior similar to her colleague Mizune. This duality between professional intensity and personal levity defines her character. A pivotal event in her background involves abandoning her responsibilities overseeing construction tasks on Tabletop Island. She instead chose to flee with Mizune Masaki. This act of defiance underscores her loyalty to Mizune and highlights a willingness to prioritize personal bonds over assigned duties when not on duty. Fūka Masaki later appears in the fourth OVA series, *Tenchi Muyo! Ryo-Ohki 4th*, serving within the Galaxy Police’s accounting department led by Ringo Tachiki, confirming her continued involvement in galactic affairs beyond her service to Minaho. The name "Fūka" (風香) combines concepts of wind, breeze, manner, or method (風) with fragrance (香), while "Masaki" (正木) signifies right, proper (正) and tree, wood (木).
