I definitely agree that Avril sounded malicious when she said it. I merely wanted to point out that monster can even be taken as a compliment depending on how it is used.

My friend and I use it in a more straightforward manner though, because we are aware of how different we are from most people. Different is not negative, so I am fine with that.

Avril is pretty childish, especially when it comes to her feelings for Kujou. She should just grow up and give up. There is NO way she can defeat that spring of BAAAWHHH.
