Ok... I'm gonna take a stab in the dark here and say that it says 忌々しいつ。 Something is provoking her? And for that matter, why would anyone want to provoke poor, sweet, innocent, hot, sexy Kyonko?

You're sort of correct. It's most likely 忌々しい～ which pretty much means (by itself) "Damn it."

It says 忌々しい〜.

Yeah, you're right, darkgray and LaC... That's why she looks upset....

I fucking hate handwritten kanji...
