Good luck with your cosplay of her!
I love her as a character, though the fairy obliviousness is also a point for them. It's no surprise that Watashi is on my list as well. We often point out how no one has real names, except for the fairies.
I get filled in on a lot of stuff that is missing in between the back-tracking episodes though, at least since it got to the first book of the light novel. I'm not reading it, but someone else is, who I watch the anime with~
