It's pronouned as "Egiru", but it is NOT his official name. His official name is "Agil", derrived from Andrew Gilbert. The raw anime says "Agil" (see the trade window in episode 8 or Kayaba's log out list in episode 14). We have 0 references that would imply "Egil", while we have references for "Agil" and we have a logical explanation for such a spelling, so, unless Reki writes "Egil" in English in the novel, his official name is "Agil".

If you doubt any other name, please see Official Naming. We list all the names of the characters used on the wiki, as well as any references we have to prove the chosen spelling. Non-bolded names are the only ones that do not have any references and may be changed if we have a good enough reason to do so.
