Fate/Prototype: Fragments of Sky SilverEdit
Elza is the master of Archer during the 1991 Tokyo Holy Grail War.
On the first day of the Grail War, Elza summons Archer.
At one point in the war, she attacks Tatsumi Kitano in Akihabara. When she met him, she heard that his wish was to "Save this city (Tokyo) and people who live in it." Even though he knew Elza was a Magus, Tatsumi bequeathed his wish to her; shocking her.
Before Archer fought against Rider, Archer asks her what it was that she truly desired. Elza states that she wants to fulfill Tatsumi's wish. Understanding her real intentions, Archer goes to fight against Rider in order to save Tokyo and its people.
Forced by Manaka Sajyou, she uses up all of her Command Spells to amplify Archer's Magical Energy, enabling him to use Stella at full power in order to defeat Rider. After Rider's demise, Elza cries as Archer fades out of existence. Elza is not seen after this point, however, Caster speculates that she must still be crying for Arash even now.
On the last day of the Holy Grail War after the Holy Grail's destruction or sealment, Elza is seen looking up at the morning sky on the rooftop of the Hilltop Hotel where she is staying. Having sensed the subsequent earthquake that followed the Grail's destruction, she immediately understood that it meant the end of the Holy Grail War. She also somehow found out the truth about the Holy Grail War either from Manaka or Sancraid.
As she thinks about Archer again, Elza starts to cry and calls out his name repeatedly. Having accepted his death, Elza says goodbye to Archer. She then forces herself to perk up after crying a bit more. She then declares to herself that she will cheer herself up, pack her bags and go to the nearest church to see Sancraid. She will then put on her best pitiful woman performance and try to tolerate Sancraid's gloats. She then also declares to herself that after finishing her reports at the Church, she will go back to her hometown and visit Luca's grave. She will then tell Luca all about Arash.
Elza utilizes Elemental Conversion Magic.
