Otoka Masaki serves as one of Seto Kamiki Jurai's Ladies in Waiting, directly under Minaho Misaki's supervision in her sub-group. She holds the position of second-in-command within Minaho's team, noted as capable yet relatively inexperienced. While Mizune Masaki formally outranks her, Otoka's role proves crucial to Minaho's operations, mirroring how Minaho supports Seto; both subordinates are indispensable to their leaders. Her team undergoes significant disruption when Mizune abandons her duties overseeing construction on Tabletop Island and departs with Fuka Masaki. This event, detailed in *Tenchi Muyo! GXP Paradise Starting*, dissolves their original group. Consequently, during the fifth OVA season, Otoka works independently as an assistant to Ringo Tatsuki. Otoka appears during preparations for Nobuyuki Masaki and Rea Masaki's wedding in the fourth OVA series (2016). She arrives on Earth with Minaho, Mizune, and Fuka as part of Minaho's accounting department team, participating in interactions with the Masaki household and guests while fulfilling her responsibilities. A distinguishing personal detail is that Otoka is the only member of her immediate group confirmed to have a boyfriend, though specifics about this relationship remain unprovided. Her narrative involvement centers on her professional role within Jurai's administrative structure and her adaptation to team changes after Mizune's departure.
