Wow some people really think Yukiji is a funny character? When serious, she's actually 100 times more interesting than when comedic mode is on. She's a painfully unfunny and annoying character. I get that you shouldn't take things like lack of responsibility and openly theft behaviors in a gag manga seriously, but I just don't like her. Yes I don't take it seriously, but seeing her casting all problems on responsible and can't-say-no people like Hayate for 8 out of 10 times of all appearances without giving a single thought about it whatsoever is annoying to me. No matter how I look at it.
At least, have the balls for once and make her take accountability, or at least acknowledge her own actions for once (doesn't need to be "oh I finally understand my actions are bad", just at least know what you're doing, like in this chapter for instance). She lacks so much self-awareness in a not-so-amusing way, that it just isn't funny. If she were anyone but a teacher then I'd probably be more tolerating.
