Also check out this: http://blog.livedoor.jp/mix921/archives/52467523.html. I'll delete it as soon as people see it, and it is a big list of comparisons in Japanese which aren't needed, anyways, but on a sentence, it says that her name is Aguri. I translated it, and the way you wrote it, 円亜久里, it is correct, and if you translate it, it is, 円 is Madoka, and 悪久里 is Aguri. So Aguri is her name. I don't know if it is enough of evidence, but the only thing is to see the next episode. And the sentence is:

In Japanese (the bold one is the name): 彼女の名前の 『アグリ』ですが、似た名前は現代文とかで見たことがあるでしょう. アグニ.

In English: Her name is Aguri, this name might be similar to the word. Aguni. ''Aguni kind of the translation of Agri. Aguni is just a refrence, as shown there, no need of that anyways.''
