Kayneth visits Risei and asks for his reward for Lancer helping defeat Caster. Risei agrees to reward Kayneth a Command Seal before Kayneth kills him to ensure the other Masters don't get one as well. However, Sola was kidnapped by Maiya during the battle at Mion River which she also cut off Sola's arm containing her Command Seals. As Kayneth scolds Lancer and mocks his chivalry, Saber and Iri, tipped off by Kiritsugu, arrives at Kayneth's hideout, where Saber wishes to finish her duel with Lancer which he agrees. As Saber and Lancer duel, Kiritsugu confronts Kayneth and having taken Sola hostage, gives Kayneth a magical unbinding contract that he will no longer harm or kill him and Sola if he does one thing for him; use up all of his Command Seals to force Lancer to commit suicide. Desperate to save Sola, Kayneth does so which Lancer curses everyone around him before dying. But because the contract only applies to him, Maiya snipes Kayneth and Sola, killing her instantly. As Saber ends Kayneth's suffering, she finally calls out on Kiritsugu for the terrible and dishonorable things he'll do to win which he retorts there's isn't anything honorable about chivalry and he will do everything to win to ensure his and Iri's wishes to save the world. As Kiritsugu leaves with Maiya, Iri collapses from exhaustion.
4. The Eighth Contract
Kirei discovers Risei's body and informs Tokiomi. Kirei is saddened over his father's death, although Archer suggests that his sadness is due to not having the chance to kill his own father himself. Maiya informs Iri and Saber that Tokiomi wishes to discuss an alliance, and Iri agrees to go to the church to discuss the offer. Before his meeting, Tokiomi visits his wife and Rin, giving his daughter a spell book and some wisdom before leaving. During the meeting between Iri and Tokiomi, Tokiomi suggests a temporary alliance to defeat the other contestants first. Iri agrees, but on the condition that Kirei leaves the city and can no longer be involved in the Grail War. Tokiomi complies. As Saber, Iri and Maiya leave the church, a sickly Iri reveals to Maiya that she is actually the embodiment of the Holy Grail in human form and will die to form the Grail once the war ends. Maiya promises to protect her until that time comes. Meanwhile, Kirei is preparing to leave, but reveals to Archer that his father's dying act was to leave Kirei the remaining Command Seals, restoring Kirei's ability to be a master in the War. He also reveals the secret reason behind the war; the Holy Grail can be activated only by the sacrifice of seven Heroic Spirits. Thus, even a victorious Servant must die - which is why Tokiomi is reluctant to use his command spells, as he needs at least one to command Archer's suicide should they be triumphant. Furthermore, Kirei still wants to explore his dark desires, and Archer yearns for a more stimulating master. Later, Kirei meets with Tokiomi, who gives him guardianship of Rin should anything happen to him, and an Azoth dagger as a symbol of his completed apprenticeship. Kirei then stabs Tokiomi in the back with the dagger, telling him that, just like his own father, both men never really understood him. With Tokiomi dead, Archer and Kirei form a new contract as Master and Servant.
