These twin martial artists appear during Miyuki's Wonderland journey, directly inspired by Lewis Carroll's Tweedledum and Tweedledee. They wear identical mandarin gowns and initially present themselves as seemingly cordial figures, offering Miyuki formal self-introductions. This demeanor swiftly shifts to antagonism as they launch an attack explicitly aimed at removing her school uniform, employing a coordinated combat style to subdue her. Encountered immediately after Miyuki meets the Doorway Girl and early in her initial exploration of Wonderland, the twins serve as chaotic obstacles she must escape. Their presence and role are consistent across both the manga source material and the animated adaptation of the first chapter.
