Filia was that we used because the game site linked her profile as [...]Filia.png and then some magazine wrote her name as "Filia". However, C9 then discovered that in-game footage (previews) used "Philia" and some new magazine also used "Philia". Guessing that the previous two usages were just mistakes.
