A Visitor Approaches Lightly.At night, Shirou and Saber return home after their battle with Kuzuki and Caster, but Shirou hides the fact that he 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, Shirou returns home, where Rin suddenly arrives unannounced. Shirou, Saber and Rin proceed to formulate a viable strategy to deal with Caster, which is a full-frontal attack against Ryuudou Temple. However, Saber and Rin fear that Caster might opt to destroy the entire temple if she is cornered. After dinner, Shirou meets Rin in the courtyard, where she muses that Shirou's home is more welcoming than her own, and that perhaps it is better that Shirou did not adopt the lifestyle of a true mage. Although Rin became a mage because she personally enjoys studying magic, Shirou learned magic because he wants to help others. A frustrated Rin cites that it is not right for him to put the happiness of others above his own. She stays at his home for the night after telling him that she plans on punishing him the next day. Later that night, Shirou goes to the shed to practice strengthening magic. Saber comes in to check on Shirou and takes notices of the left side of his body being numb. Archer then arrives and is aware of the symptoms, knowing the precise side effects of projection magic. The pain that Shirou has been feeling is due to activating magic circuits that have long laid dormant. After repairing Shirou's magic circuits and noting of a similar experience, Archer warns Shirou that his ideals are meaningless and doomed to fail, something Shirou denies.
