A chibi, minigirl characterization of Kirisame Marisa with mouse ears, as well as a tail with a bow tied to the tip. She is often drawn without her witch hat, though this is not consistent. First created by Yuasan, she quickly gained enough popularity to sell her own merchandise.
Mouse Marisa can speak, though the only word she knows is "now!" (なう!), which is sometimes depicted as a demand for the viewer to feed her cheese immediately.
