Headcanon (AU+OU)
→ Kim's family is poor, or her father left and her mother struggled to make ends meet. This is why she charges for everything and has a heavy reliance on money, also why she barely trusts people to begin with.
→ Her great-grandmother was a witch previously, but the magic skipped her grandmother and mother, passing it down to Kim instead. This is possibly why she uses regenerative magic instead of destructive magic.
→ While she seems like she doesn't want a relationship, her self-consciousness is stopping her from being physically involved with someone. She doesn't think anyone can like her for who she is, and this includes romantic-wise relationships.
→ She has a hell of a sweet tooth. She gets all gooey-eyed and drools over things even as simple as an ice cream sundae. She has a fast metabolism which means she can eat sweets to her heart's content.
→ Once someone's won Kim's affection, she's very protective of them to the point of being borderline possessive. She will go through Hell and back just to keep them safe.
→ Kim knows a couple of hand-to-hand fighting styles. Her small stature means people overestimate her ability to fight, and she uses this to her advantage if she's caught without her Weapon partner.
→ She and Jackie board in the Shibusen girl's dorms even though they've both graduated to the EAT class. They share a bed because Kim has nightmares about being found out to be a witch, and even after she was shown by Ox that it was okay that she was a witch they still sleep together.
→ She's ticklish, but only in one specific spot and only Jackie knows where it is.
→ Her soul is a little lighter purple than that of other Witches souls, due to having healing magic, and has dollar signs for eyes and a raccoon tail, along with raccoon-type stripes around it. People with Soul Perception will see her soul personality as greedy, distrusting, self-conscious, bitchy, unsure, closed-off.
