I love that scene where Kenshin flies at him to hug him(he's such a sweet guy!) and Hiko dodges and lets him run into the wall!

And says. "I don't think I'd like a hug from a man, stupid apprentice!"

Although there are times when he is quite wonderful and wise with Kenshin. And even loving, in his own way. Such as at Tomoe's grave when he finds Kenshin crying in the rain.

He's so funny! But, people think his horribly sarcastic humor is mean. I find it.... the perfect counterpoint to Kenshin's earnestness.
