A fleeing Shirō is eventually cornered by Rin, who offers to spare his life if he gives her his Command Seals. However, he refuses, prompting Rin to try and kill him. Both are then distracted by a scream downstairs and he and Rin find an unconscious girl. As Rin attempts to heal her, a dagger flies through an open door, aimed for Rin, but Shirō blocks it with his arm, wounding himself in the process. He runs outside to find the female Servant, which is of the Rider class, and repels an attack by her. Shirō considers summoning Saber via Command Seal, but decides it is too risky to get her involved and resolves to confront Rider himself. Rider resumes her assault, and Shirō is nearly killed by her until Rin rescues him. At Rin's home, Shirō and Rin decide to form a temporary truce to find Rider's Master.

Saber yelled at Shirou for not summoning her when he was in danger. Saber starts to go to school with Shirou. When Rin appears and says she will walk with Shirou to school, Saber allowing this after Rin talked to her. She explained that this way enemies may think it's a trap to not see Saber with him so they are less likely to attack.Rin explains that there should be spell marks around the school and if they destroy those it will delay the activation of the force field but not destroy it, and most likely force the master out of hiding. After school Shirou and Rin work to find spell marks and destroy them. They end up destroying a good amount of them and call it a night.On the way home, before Shirou gets anywhere but after Rin leaves he feels something really strong. He goes to investigate it and feels its coming from the archery club.

Shinji says things like how he has no intention of fighting and he was just dragged into this war. He asks to make an alliance with Shirou to go after Rin but Shirou refuses. Shinji says because he doesn't know magic other Masters can't detect him so that means Shinji isn't the other Master Rin was detecting, meaning there is a fourth one at the school. Before Shirou leaves Shinji tells Shirou about how one of the Masters has set up base at a temple.Shirou gets home and is yelled at by Saber and Rin, Rin having come over after Shirou didn't come home. Shirou tells them about Shinji and the Master at the temple.Shirou and Rin both agree, against Sabers judgment, that they should not attack the temple yet as they don't know what Servant and it may be a trap.Saber brings up again with Shirou the temple but Shirou insists that they won't be going.

Saber is eager to go to the temple but Shirō has insisted that they won't be going because it seems too dangerous. Nonetheless, as soon as Shirō falls asleep, Saber heads off by herself to the temple, not only to be confronted by the servant identified as Assassin. Unlike any other servant, Assassin actually reveals his true identity to Saber, as Sasaki Kojirou. Although the talking ends here and the fighting begins but while this is going on Rider sneaks past them and enters the temple to fight some woman. Who is this mysterious woman and was Shinji planning this all along?

Saber and Shirou practice for a bit, Saber completely dominating over Shirou and not training how some would think but just a straight out attack between the two of them where Shirou keeps getting hit and slammed to the floor multiple times. Saber comments on how Shirou is doing fairly good and she is amazed by his zeal and things. Thy take a break and Shirou asks Saber what wish she wants granted if she got the Holy Grail.Shirou heads out to buy things for lunch and he runs into Ilya. They talk for a bit about their past and Ilya says where she came from. Shirou tells her that he inherited something precious from him. He says how he didn't receive his fathers Magic Mark but says he is still a master, just a half-assed magician.Shirou gets home, he talks with Rin who says at school Shinji asked her to team up with him. Rin says she rejected him though, saying she was already partnered with Shirou and she trusts him a lot more.Archer says how much of a failure Shirou is and that he would never be able to defeat a Servant. He does however seem to give him some advice saying that, If you cannot defeat someone, imagine something in your head you can defeat them with, for that is all you will be able to do.

After a mornings training session with Saber, Shirou is then straightaway dragged off by Rin for some more training of her own. While this is going on Shirou receives a phone call from Shinji, asking Shirou to meet him at the school. Because it seemed urgent Shirou heads of to school and is greatly shocked by what he sees. Shinji shows his true colors and says how he wanted to show Rin how he was superior to Shirou and that he would defeat him here. What will happen to Shirou and does he have the will to fight off a Master and his Servant, alone?

Shirou is very worried about the well being of the students, staff, and of the school after yesterday's events, he's especially worried about Taiga who seems to be recovering well. Shirou is now determined to put an end to this and plans to go after Shinji before he can make another force field and with Sabers support they head out. However before that, Shirou has some important information to disclose to Rin about Shinji's Servant, Rider about the Noble Phantasm she used.

Shirou falls asleep and sees a dream of a flashback of Saber's past. We see Saber in plain olden time cloths walking up to a sword in a stone.Saber wakes up and notices Shirou is gone. She talks to Rin and despite Archer's objection they go looking for him, suspecting he has been kidnapped by an enemy.Shirou wakes up in Ilya's house as her captive. Ilya says how she wants Shirou to become hers.

Rin, Saber and Archer just outside of Ilya's mansion. They see Ilya walk out so they soon head inside to rescue Shirou.Rin asks Archer to slow Berserker down by himself while the rest of them escape. Archer says fine but asks if it's ok to kick Berserker's ass while doing so. Rin kind of smiles and they run off, leaving Archer to fight Berserker. Before they leave Archer yells out Emiya Shirou. Shirou stops and Archer tells him, Get this straight: You are not one who fights. You're nothing more than one who creates. Throw irrelevant thoughts away. There's only one thing you can do. Master that one thing! Archer then causes part of the ceiling to fall separating them so that Shirou will run away.The fight between Archer and Berserker commences.

Archer has been defeated by the unbeatable Beserker and now Shirou, Saber and Rin are trying their best to escape the same fate. They are able to find shelter to bide some time, because Shirou has to find a way to replenish Saber's mana while Ilya looks for them. With Archer's sacrifice, Rin is that much more determined to get out of this alive and comes up with an elaborate plan. The beginning of a fight between Saber and Berserker commences.

The battle is at the turning point, where Rin is about to be squashed by Beserker and Saber is unable to save her. As a last resort Saber decides to use her Noble Phantasm to defeat Beserker, no matter how it would affect her. Realizing that Saber could disappear from this, Shirou forces her to stop and decides to take matters into his own hands.The advancement of Shirou's character as we find what he is really able to do.

Shirou wakes up after having yet another dream of Saber's past and is clearly shaken up by what happened. That morning, during breakfast, Ilya is introduced by Rin as another person to be staying there for a while and Taiga seems to accept it well. Meanwhile there have been news on even more gas leaks, meaning that the Master at Ryudouji seems to be escalating his plans. While Shirou, Rin and Saber are planning what to do about this, Ilya enters the room with a great deal of information on this topic.

Shirou, Saber and Rin are at the steps to the temple.Assassin appears, he lets Shirou and Rin go past and fights Saber. Shirou and Rin head past Assassin and past him they see Sakura, in rather odd cloths who is in what seems to be pain as she is glowing red. She is in a pit arena area and as they prepare to go down there they are attacked from behind which Shirou notices and blocks the attack with Archer's swords. Souichirou appears and Shirou tells Rin to go ahead as he fights Souichirou and she goes to rescue Sakura. Meanwhile Saber and Assassin fight continues on. They compliment each other on being one of the best swordsmen they have ever faced and Assassin tells Saber that his identity, Sasaki Kojirou doesn't really exist. He is fabricated from people's minds of being a great swordsman so he is a fictional heroic soul. He says he has no desire for the Holy Grail therefore; his true desire is this, a fight with a worthy opponent.We find out more on the past of Rin & Sakura and how they once were bestfriends. Caster is watching this smiling says she just needs one magician for the sacrifice. Everything seems to be going as she had planned.

Saber's fight with Assassin and Shirou's fight with Souichirou reaches its climax. Souichirou shatters Shirou's blades again, sending him flying down to where Rin and Sakura are and it is upto Saber to defeat Assassin and make it down in time to save everyone. With Saber still affected by Caster's Noble Phantasm Rule Breaker, she isn't able to defeat Caster when all of a sudden their fight is interrupted by an unknown Servant. It seems that Saber is familiar with this Servant, but it turns out he's the eighth Servant in this Holy Grail War.In light of the appearance of the eighth Servant, Saber finally reveals to Shirou the shocking events of the previous Holy Grail War.

Shirou takes Saber out on a date to try and convince her not to use the Grail and go back to her own time, but to stay in this time instead.

With the appearance of the mysterious Archer-class Servant, Saber tells Shirou to escape while keeps him occupied. However Shirou, knowning that Saber couldn't defeat him before, foolishly tries to attack him head on and with the snap of his fingers Shirou is quickly defeated. Will Saber have the strength to defeat him, esepecially now knowing his true identity; owner of all the world's treasures, the King of Heroes of ancient Uruk, Gilgamesh.Kirei Kotomine also seems to play a major part in the Holy Grail War and it's not because he's the mediator.

Saber can't seem to get Shirou of her mind but that is short lived when she finds out from Rin that Ilya has a terrible fever and may not last long. Meanwhile Shirou is still missing, having not returned from the night before and Saber knows that there's only one place he could be, the church. It doesn't take long for Saber to notice the wounded Shirou on the floor but she's unable to do anything because she's greeted by Lancer. Saber must decide whether she truly desires the Holy Grail as she's given a means in acquiring it.Kirei Kotomine reveals what really happened at the end of the last Holy Grail War and what will Shirou and Saber do knowing the true meaning of the Holy Grail?
