Well, that all depends on what you define as 'a jerk'. Because if we're talking about people who are not very nice 90% of the time, I have no right to judge. :)

But in all honesty, if I ask Captain Hitsugaya a question, he won't lead me around in circles by my nose--he'll answer me honestly. Maybe not in a very eloquent or polite manner, but an answer is an answer. Also, we both seem to suffer from what I like to call 'appearance vs. reality discrimination'--I suppose that could be seen as something we have in common. He is not daunted by my outward appearance, which saves me the trouble of proving I'm not what I seem.

It's also highly entertaining to prod at him with jokes he'll never laugh at.
