The Reward for the Fight to the Death.Outside Ryuudou Temple, Saber engages Assassin in battle, but she is shocked to find that she cannot break through his defenses despite her advantages in strength and agility. Inside Ryuudou Temple, Caster reveals that she summoned Assassin as her own Servant using magecraft. Archer claims that Caster broke the rules of the Holy Grail War and insults her tactics before engaging her in battle. After a while, Archer manages to critically wound Caster, prompting Assassin to prematurely finish his assault on Saber with his secret technique, Swallow Reversal, which is able to cut down a swallow in mid-fight. Archer refuses to finish off Caster, as his main goal is to ensure Shirou's safety, since he does not believe in senseless slaughter. Caster claims that Shirou and Archer are alike in their ideals, although the two reject her offer to join forces with her. Despite Shirou's protests, Archer allows Caster to flee, knowing full well that she will continue to kill innocent people. Shirou is disgusted by Archer's willingness to allow collateral damage, yet Archer defends his ideals that Shirou criticizes against, citing that the collateral damage would extend far beyond Fuyuki City if Caster were to win the Holy Grail War. Archer slashes Shirou in the back when the latter is unable to accept this. Shirou staggers out of Ryuudou Temple and is tended to by Saber, who survives Assassin's Swallow Reversal. Archer continues his assault, but is distracted by Assassin, who allows Saber and Shirou to escape after being impressed by Saber's power. At the apartment dojo, Shirou asks Saber to teach him the art of swordsmanship, now unwilling to lose to Archer again.
