Yes, I'm not very familiar with furiganas...
But I think too to people who search this CD on VGMdb: because this CD is known everywhere with the title "Marcello Monogatari", they'll write this title on search engine and they find nothing here...

So i don't sure that a lot of people attribute some importance to a perfect romanization or not...
Well, all I can say about the lyrics, I have " 佐藤ありす" in my booklet (no scanner, sorry

)
And so Anime News Networks do a mistake too (name is also Arisu Satô):
http://www.animenewsnetwork.com/ency...le.php?id=8946
And here it says that "Arisu" is the Japanese romanized form for the English name "Alice".
http://sailormoon.wikia.com/wiki/Arisu_Satou
So Arisu Satô (Satou) is her name in Japanese, and Alice Sato (or Saitou?) her name in English?
And on your artist page on VGMdb, you must write the name in English or in Japanese (romanization)?
Not easy...
