Heh, this reminds me a little countdown I once did. While watching Mirai Nikki, I counted down and categorized Yuno's kills.

So with that said, my expert oppinion is, that Irene killed herself, so nobody gets a kill (or a frag). Erza only injured her; that's a "Serious Injury" point. Since Wendy enchanted the weapon, that nets her a "Serious Injury Assist".

You're welcome. :D
