Kuppi is a minor supporting character in the anime Slayers Revolution. She is a female humanoid fish with no hair and black eyes. In her only notable appearance, she is captured by a band of pirates who mistake her for a beautiful human woman. When Lina Inverse storms the pirate hideout and the captain attempts to use Kuppi as a hostage, Kuppi reacts in terror upon hearing Lina's full name; she immediately begins recalling and reciting numerous frightening rumors about the infamous sorceress. Another pirate chimes in with even more horrifying stories, and the terrified crew ends up groveling before Lina, resulting in Kuppi being inadvertently rescued. Kuppi's personality is not deeply explored, but her reaction indicates that she is well-acquainted with Lina's fearsome reputation and is prone to panic when confronted with danger. Her primary motivation is self-preservation, as she is an unwilling captive caught up in events beyond her control. Her role in the story is limited to this comedic sequence, which serves to reintroduce Lina's notoriety and diffuse the pirate threat through Lina's infamous name rather than direct combat. Kuppi has no significant relationships with the main cast and does not undergo any character development. As a fish woman, she likely possesses aquatic adaptations, but no special combat or magical abilities are displayed.
