I don't know... If Okayado intended for the surname to be non-Japanese, you'd think he'd have told the merchandise people to make sure the name is spelled "Smith", just like how Centorea's surname and Doppel's name ends with a silent "s" and "l" instead of "su" and "ru".

Then again, maybe her non-Japanese parent is a naturalized Japanese citizen who adapted their non-Japanese surname into the native language by choosing the right kanji, with the furigana being in katakana form instead of the usual hiragana to denote the foreign nature of the name? I wouldn't know for sure, since I'm not exactly well-versed in this subject.

Bottom line is, her surname is explicitly spelled "Sumisu" in the merchandise, in a way that seems deliberate rather than a mistake.
