Ryo-Ohki, a cabbit hailing from the magical realm of Juraihelm, serves as advisor and companion to Sasami Kawai in her role as the magical girl Pretty Sammy. Diverging from his female counterpart in *Tenchi Muyo!*, this male iteration speaks fluently and retains the ability to transform into a humanoid boy. Commissioned by Juraihelm’s queen-elect Tsunami, he guides Sasami through her duties as a champion of justice, providing tactical support and clarifying her magical abilities. In *Magical Project S*, his role expands to practical assistance, collaborating with Sasami’s father, Ginji, to merge the latter’s non-magical expertise—SWAT tactics or NASA-trained problem-solving—with mystical strategies, forging a dynamic alliance between enchantment and pragmatism. The *Bonus Theatre* specials highlight his proactive nature, such as dissecting Pretty Sammy’s unconventional techniques in "26 Secrets of Sammy," including her pigtails functioning as extra limbs or her belt expanding into a wheel-sized weapon. He directly intervenes in conflicts, exemplified in "Video-Jack Misa," where he disrupts Pixy Misa’s scheme by replaying a clip from the main series to reaffirm her prior defeat. Ryo-Ohki displays keen awareness of hidden narratives, notably exposing the Kawai family’s concealed basement and its butler, Alfred, in "Secrets of the Kawai Family," startling even Sasami with revelations about her home. His interactions weave humor into responsibility, whether sidestepping inquiries about Pixy Misa’s "Pretty Wink" target demographic or navigating Sasami’s avoidance of discussions about her disorganized room. Consistently loyal and adaptable across media, he shifts effortlessly between combat support, expository guidance, and comedic interludes. His sporadic use of humanoid transformation underscores versatility in both magical and earthly contexts. While his origins remain tied solely to Tsunami’s directive, his steadfast presence solidifies his role as a cornerstone in maintaining the delicate equilibrium between chaos and justice within the series’ whimsical yet tumultuous universe.
