in order from most to least preferred, for all publications you should use the name "Elira".
note that even though "Elira" is my professional name for music, it is still my name, and not a moniker/ pseudonym.
in the case someone were to write about me in Japanese, Korean or Mandarin, i included how i'd prefer my name to be written. for ease, honorifics are here too. my birthyear is 2005 in case someone wanted to write my age with the korean system as opposed to the western one.
