Fate/Prototype: Fragments of Blue and SilverEdit
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 Elsa was a Magus, Tatsumi bequeathed his wish to her; shocking her.
Before Archer fought against Rider, Archer asked her what it was that she truly desired. Elsa 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, Elsa cries as Archer fades out of existence. Elsa is not seen after this point, however, Caster speculates that she must still be crying for Arash even now.
