After the battle Goku flew around the city searching for a place to stay and eat. He doesn't want to steal because it was not in his nature to do that he also couldn't go fishing because he was afraid somebody would notice him. He then decided to stop at a park to think about what he is going to do.
"What am I'm going to do? I'm hungry but I don't want to steal. Chichi would hit me if I do that. The fish around here is small. I could go fishing at the sea but someone would notice me if I do that." thought Goku. "Also I had already gather enough attention as it is. Going Super Saiyan was not a good idea." He thought how Illya would scold him if she knew what happened. "Alright that is enough. I have to stop this holy grail war fast so that I could revive Illya" thought Goku while standing up. But then he sensed a servant was nearby.
"Well.. well, what do we have here." said the servant as he comes out of the shadow. The servant looked like a man. The man was clad in blue. He was carrying what looked like a spear. "You look strong, maybe you could provide me enough energy" said the man. He didn't notice that Goku was a servant because Goku had lowered his energy to be a little stronger than a human. "Before you die let me introduce you to your killer. My name is a secret but you can call me Lancer". "I'm sorry for doing this but my master forced me to" Lancer said while beginning to to thrust his spear. Just when Goku was going to react someone came in between them and stop the spear. The sound of metal clashing can be heard by everyone there.
Goku looked at the person in front of him. It looked like a girl. But this girl was wearing armor and she has yellow hair. Goku sensed that there are 1 more person coming here. He sees a boy coming here. He feels more powerful than the average human at least."Saber" the boy yelled. "Be careful" the boy continued. "Don't worry Shirou, you better take care of that guy first" said Saber. Realizing that, Shirou went to Goku. He asked Goku to go out of there. Goku didn't want to so he pretended to be hurt. Because of his sense of justice, Shirou said don't worry he will protect him.
Shirou then went to help Saber with the fight. Goku then from the sidelines watches the fight that was going on. He could see sparks flying when Lancer's spear strike the invisible weapon that Saber is holding. Shirou then join the fight using the same weapon that Archer was using. Kanchou and Byakuya both manifested in both his arms.
Lancer succeeded in making Saber off balance and when she was almost being hit by the spear, Shirou jump in and uses his blade to counter the spear. He goes on a full on assault not caring about his body. Lancer was surprised by this but only for a second. After that Lancer began to counter every strike that Shirou dishes out. The fight was really one sided. It wasn't fair for Shirou who was human to fight a servant. "Get out of the way Shirou" yelled Saber as she continues the fight with Lancer replacing Shirou.
Lancer was so excited to fight someone. Just when he was going to activate his noble phantasm, Kirei then commanded him to go back saying it was enough. Eventhough he was mad at Kirei he can't do anything because Kirei was his master. "Sorry Saber but my master has commanded me to go. I hope we can meet in the future." Lancer then flee from there.
Shirou than went to see Goku who was pretending to be hurt. As Shirou and Saber went to see Goku. They hear a grumbling sound. "Is that you Saber. I know you can eat a lot but that is going overboard" said Shirou. "No it wasn't me." Saber said angrily. "Sorry but it was me" said Goku while rubbing at the back of his head. "Wow you made that, you must be really hungry. How about you come to my place and have something to eat" asked Shirou to Goku. "Wait Shirou you remember what Rin said. We cannot involve normal people into this." Saber said reminding Shirou. "Oh, don't worry. There is always a lot of weird thing happening around me since I was little. I am also a martial artist. So you don't have to get scared that I will tell anybody anything about this." said Goku.
"See Saber it's alright. He seems really trustworthy. I can feel that he is really important somehow. Also Rin isn't here, so we don't need to follow all of her rules and maybe he can also teach me some martial arts while he's with us." said Shirou full of passion. Saber sighed. "Your sense of justice is too big Shirou. Someday it will bite you in the back but for now I will protect you. But you must become stronger so we can get the grail.". "Don't worry Saber, we will get the Grail." Shirou said. He then turned around and talked to Goku telling him that it was okay for him to follow. Saber was still wary of Goku. Goku notices this and decided not to show all his power to her. There is also the concern that his power is still slowly slipping away. It was just a matter of time before he would evantually vanish. He needed to end this war fast.
At Emiya manor.
Shirou was cooking with Sakura in the kitchen while Saber, Taiga and Goku was waiting for their dinner. Goku was sleeping while he was waiting for dinner and Taiga was also sleeping because of Goku. Sakura was there when Shirou, Saber and Goku went there. She was waiting for Shirou to come home. Shirou explained that Goku was a martial arts master that he found on the street to teach him. Taiga was still suspicious about that and decided to call the police but she stopped when Goku tapped lightly at her back to knock her out. He then apologizes and said that this is the only way because he really wanted to eat. They all eat and Goku manage to convince Taiga so he could sleep there. "At least it's not a girl this time" Taiga said go himself. They all went to sleep.
Somewhere
"Well I think it's time for me to meet Saber. Also I haven't sense that strong energy that I sensed sometime ago" said Gilgamesh. "Maybe he died. Well a mongrel is still a mongrel no matter how powerful he is" Gilgamesh said to himself.
Another place
"I managed to summon Assassin, and make him my servant. I think I will make him .guard the gate so that nothing like the energy sometime ago doesn't enter." said Caster. "Well dear, don't worry I will get the Grail for us. We would always be together." said Caster to her master.
