I was just wondering how to pronounce Rivaille? (Sorry if I'm writing this wrong I haven't read the manga and I had hard time catching up with the name thing) also , someone wrote this on a question and I wanted to know if it's tru - " Rivaille" came from the romanization of his name, リヴァイ, which is "Rivai". So without word of god the name could have really been Revi, Levi, Rivaille, Livai and so on. But yes, Isayama has confirmed that he intended the name to be Levi"
Haha you already answered your question. Isayama has confirmed that his name is Levi. But since this combination of letters is not working in Japanese, they say Ribai which is closest to Levi, the ‘someone’ was right
