Thought I should just mention this.

Eir Aoi, the artist who sang the ED song of Fate/Zero, just opened up a fanpage in Facebook.

Eir Aoi fanpage

I found out about the page when I saw the advertisement on the sidebar.

Looks like that her maxi-single came out a few days back, October 19, 2011. Surprisingly enough, she is quite fluent in English. Or that the one writing on the page is believableā€¦

At any rate, head over to her Fanpage and like it.
