His name is rendered as Egil, not Agil, as per romanji エ (e), not ア (a). You can quarrel about the anime production team's translator mistaking the reference. SAO contains half a dozen Norse mythological references, a dozen Greek, and various others. This is not a coincidence, it's a production error.
