After the battle with Caster and Kuzuki, Shirō and Saber return home. Shirō claims he is fine so as not to worry Saber, but is clearly in pain and off-balance as a result of using projection magic. The next day, he goes to school and finds that Kuzuki is absent due to what is claimed to be an illness. After school, Shirō returns home, where Rin suddenly arrives unannounced. The two proceed to formulate a strategy to deal with Caster. However, their only viable plan is a full-frontal attack against Ryuudou Temple.
