The fall of a giant

You, Saber, and Rider arrive at the stairs of the temple just in time to witness a massive explosion. "We'd better hurry." Rider says. You and Saber nod, ascending the stairs as quickly as possible.

The three of you dash up the stairs to see the smoke clear and Berserker fading into ether. "Nooo! Berserker!" Illya cries. You clench your fist. "You made her cry." You say as you stare at Caster. Illya turns to you and runs behind you and your two servants.

"You will pay for what you've done to her and the people of the city! Rider!" You exclaim. Rider readies a battle stance in front of you, wielding her nail-chain. "We should attack quickly before she regains her Mana, Master. Even with my interference she is gaining quickly." You nod.

Rider needs no more confirmation from you to shoot herself forward in an attempt to finish Caster once and for all. Caster grins and quickly babbles out the most powerful spell she can muster from what Mana she's been able to recover so far.

Circles of Mana surround Caster before shooting out in a wave of magical bullets. You look on to see what should be impossible - Rider nimbly stepping between bullets and dodging each shot until..

You see an explosion of energy as Rider collides with Caster. When the air finally clears, you see Rider standing triumphantly over Caster's now-limp body as she fades away.
