Rukia doesn't like Danny

Rukia: Your parents are idots!
Danny: I'm aware
Rukia: What is up with Americans assuming all ghosts are evil? We aren't all bad. That's racism!
Danny:....
Rukia: Stop doing my job for me! It's my job to beat evil ghosts, not yours. I have to deal with enough half ghost boys as it is.
Danny: Hey, I'm just trying to help.
Rukia: Why won't you admit you're in love with the goth gorl?
Danny: Why won't you choose between Ichigo or Renji?
Rukia:...Touche.
Danny: Thought so.

Rukia and Danny would not get along.
