"I am so Jealous of you being able to fulfill wishes..."

Why do I get the feeling that QB is screwed despite the fact that Parsee is a low level youkai?

Parsee can manipulate jealousy...I'm having a hard time figuring out how that is a threat to Kyubey. I mean, even if he was jealous of someone, what's the worse that could happen to him?

Because He going have a hard time finding out what she want when Parsee in Jealous of almost everything that it pretty much like she want everything and more.
