Fate/Zero

Uryū and Caster return to their lair and are dismayed to see their "artwork" destroyed by Rider's fire. Uryū cheers Caster up by sharing his twisted view that God, whom Caster hates the most for Jeanne's death, is just a spectator who enjoys seeing humans do whatever they want. Impressed by his Master's beliefs, Caster plans a "grand spectacle" for God to look upon. Meanwhile, Waver has second thoughts about whether he is a worthy Master for Rider, but Rider encourages him to believe in himself. Suddenly, Waver, Rider, Irisviel and Saber sense magic from the Mion River. When they arrive, they witness Caster summoning a giant demonic monster. Rider informs the other contestants and they all agree on a temporary alliance to stop Caster before his monster destroys the city. With Rider leading the vanguard, Saber joins him to give Lancer an opening to use his spears on Caster.
