I don't recall it being mentioned at any point and I can't find any information about except for this page [1] which claims she's English. But I have a hard time believing anything on this site because of some of the other content. If anyone knows, it might be worth mentioning on the page. - The 4th Snake 21:25, June 12, 2011 (UTC)

I think the information at Chewiki is wrong. Maria-san is Japanese. But she can speak English/Chinese/... bla bla bla. --Nechigawara 22:53, June 12, 2011 (UTC)
I just find it odd that she doesn't have a Japanese name. I imagine the idea of her being English comes from the Animax Asia dub. - The 4th Snake 05:10, June 13, 2011 (UTC)

She has no known last name.

That's true. TechnicGeek10 (talk) 12:41, March 18, 2015 (UTC)

But we don't know her defined ethnicity. While she's nationally Japanese (being born & raised there), she may not be ethnically Japanese.
