Saber tells Shirou all about Heroic Spirits and Noble Phantasms. She explains why she doesn't want to reveal her true identity to him. Shirou wants Saber to stay at his place for a while. Will Fujimura approve this request?

Despite losing Saber, Shirou is determined to fight. Since Caster is protected by Kuzuki and Archer, Shirou and Rin decide to team up with another Master. Left with no other option, they set out to find Illyasviel and Berserker.

Shirou and Rin finally reach the castle where Illyasviel and Berserker are. However, there are other unexpected guests visiting Illyasviel.
