Headcanon
→ 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.
→ When Kim types in text, she uses this colour and unless she's feeling lazy or especially pissed off she types perfectly. OTHERWISE BE PREPARED FOR CAPSLOCK RAEG she also uses the following emoticons <3 >3 >| >D :3a
