Ryo-Ohki appears as a pet within *Sasami: Magical Girls Club*, distinct from other iterations in the *Tenchi Muyo!* franchise. This version possesses neither spaceship capabilities, combat traits, nor connections to Juraian mythology.

Initially owned by Washu, who serves as a teacher and magic advisor, Ryo-Ohki frequently accompanies her. The pet endures mistreatment, including subjection to Washu's experiments and rough handling. Despite this, Ryo-Ohki forms a bond with Sasami Iwakura and eventually transitions to her care, paralleling the close relationship seen in other *Tenchi* continuities.

Physically, Ryo-Ohki takes the distinctive cabbit form—a cat-rabbit hybrid—and lacks a defined gender. It exhibits shape-shifting abilities, transforming between forms, though the extent remains unspecified. Unlike other versions, this Ryo-Ohki does not speak or display human-level intelligence, functioning primarily as a companion animal.

Within the series' magical context, Ryo-Ohki assists Washu in managing the Magical Girls Club, an organization masquerading as a school cooking club. The pet’s presence supports the girls' training in controlling their innate magical abilities, though it does not directly participate in magical activities or battles.

No character evolution, background, origins, extended lore, or development beyond its role as Sasami's companion is detailed in this continuity.
