Klaus is a lot like the resident father-figure I guess.
He definitely doesn't seem very fond of Hayate for his ojou-sama.
I thought some of the censorship was in the manga as well - don't they always censor the gundams and things that are trademarked?
The fanservice shot at the first "ending" of episode 2 cracked me up. The anime now has like 1000x more fanservice than the manga.
