Differences from the Light Novel

  • Emile assessing Diablo's Warrior level is omitted.
  • Diablo and Shera's first visit to the Bridge of Ulug is changed to when they take the delivery quest instead of crossing it on their way to Faltra City from Starfall Tower with Rem.



  • The English dub gives Edelgard full sentences when speaking.
