Kaida, the Serpent. Whatever name one calls her, she's here. Both the cities and the wilderness are her home, but she seems to arrive only to fight more, and disappears for more Pokemon and training. She's not cruel though, her Pokemon know a kind owner, one who thinks constant fighting is the key to survival and keeping one's family from becoming nobodies. Now that her Pokemon is her family, she aims to protect them. She favors predatory Pokemon, seeing them as better fighters. Her name means "Little Dragon", and she takes this very seriously.

Friends

Kaida knows acquaintances and sparring partners, but friends are a little harder to figure out. One who interacts with her a lot, or participates in a dangerous situation with her, is sure to earn her trust. She also tends to sympathise with people who have truly fought for things, as her scars will show, or people with a similarly nobody past. Most Trainers can expect at least civility from her, perhaps rivalry.

Enemies

Trying to kill anyone she knows, or her Pokemon (Arceus forbid!) is a great way to get both her and her Pokemon after you. People who cause harm for harm's sake, don't expect any admiration. She chose Pokemon that hunt for a reason, any harm they cause to another is for survival, not pleasure. On a more mundane note, she tends to dislike Breeders due to not liking the idea of manipulating a Pokemon for humans, and overly rose-colored glasses can irritate her.

Love?

That is the question, is it not? Being the way she is, for Kaida, love will have to bloom on trust, and nothing less. She generally won't recognize this though, thinking that the person she's starting to fall for is just a friend she trusts lots. Anyone can play this role, with the only real requirements being that their philosophies aren't too different (Someone who thinks Pokemon should never fight would be a challenge, for example), and she trusts the person.
