Rose is a feline spy with brown fur, striking red eyes, and dramatic red eyeshadow. Her signature rose motif appears in a hair accessory and neckpiece, echoed in her dark purple bodysuit and boots—even extending to her bike helmet. Specializing in high-stakes confidential missions, she relies on cleverness and quick reflexes to achieve objectives.

She first crosses paths with protagonist Zorori during an operation to recover stolen chocolates hiding a critical microchip. Recruiting his aid to evade pursuers and secure the item, she inadvertently entangles him in her espionage world. Despite Zorori’s persistent romantic advances—including declarations of love and a gift of 100 roses—she maintains professional detachment, prioritizing missions over personal connections. Though occasionally showing kindness, such as a brief cheek peck, her focus remains unwavering. Her operations often involve a rabbit companion, sometimes complicating missions.

Rose’s storyline concludes when Zorori ends his romantic pursuit, acknowledging its one-sided nature. She appears exclusively within these early narrative arcs, with no documented appearances in films, OVAs, spin-offs, or later series segments.
