Kim has a tendency to bully fellow students by charging them money while performing tasks for them. She is the object of fellow student Ox Ford's affections, though she is often annoyed by his romantic advances. She is later revealed to be a tanuki witch who possesses regenerative powers, allowing her to heal both herself and others when injured, going against the typically destructive nature of other witches. In Soul Eater Not!, Kim is shown to befriend Jacqueline, one of her bully victims, after the latter discovers her witch identity and helps keep it a secret. In the main series manga, Kim's identity is exposed by Medusa, causing her and Jacqueline flee DWMA together and reluctantly join Arachnophobia for protection. They are brainwashed into serving the organization, but are later returned to normal by Ox and Harvar and allowed to return to DWMA.

Kim's animal theme suits her personality: the tanuki is portrayed in Japanese folklore to be associated with wealth, gold and money. Likewise, Kim is also very attached to money. Also, tanuki in mythology are said to have healing powers and transformation abilities, both of which are associated with Kim. Like tanukis, Kim also enjoys dining on omelets.
