Earth (2004)

Shirou residence

She stood up and looked at them. "Shirou and Sakura" Rin says.

"I never expected you two to be the new master" Rin says.

"so you two already know about the Holy Grail war" Rin ask them when she nodded at him.

"Kiritsugu taught me everything about the holy Grail war" Shirou replied.

Archer, Saber and Trunks was looking at each when Rin looked at him. "you must be Trunks Brief" Rin says.

He was surprised. "how do you my real name" Future Trunks says.

"in our school they taught us about you and the other heroes during the age when the Androids was killing innocent people" Rin says.

"so I know a lot about you like example" Rin says.

"Trunks Brief the son of Bulma Brief and Vegeta" Rin says.

"wait you know my father" Future Trunks says in shock.

"yes know the Vegeta is the Prince of all the saiyans" Rin says

"you're was able to transform into super saiyan and super saiyan two" Rin says.

He was going to say something but she interrupts him. "Bulma told everything about her adventures that why it appears in our history" Rin says.

"even the mage society feel bad the saiyans are extinct" Rin says as Shirou and Sakura was confused.

"no they didn't feel bad the saiyans getting kill by Frieza" Rin says.

"they're known the half blood have a lot of potential so if the half blood have the mage bloodline he would be a lot more stronger" Rin says.

"yes I understand…is kind weird the everyone knows about my history" Future Trunks says.

"is normal you was responsible the we was able to have a peaceful life" Rin says when he nodded at her.

She was looking at her and saw the Saber was looking at them. "Shirou are you curious about her true name" Rin ask him.

"Saber can you tell me you true name" Shirou ask her.

"is unwise to know my true name" Saber says.

"Saber just tell us" Shirou says.

"is better if you don't know my name most likely you would tell you friends" Saber says while looking at them.

"I'm going to guess you name" Shirou says when she nodded at him.

"Jeanne D'arc?" Shirou ask her.

"do I look remotely French do you" Saber says angry.

"Saber can you give me a clue" Shirou says.

"I'm going to give you three" Saber says.

"I was born in Britain, I was a knight and I hide my gender when I was alive in the era" Saber says.

"a famous knight" Shirou says.

"Mordred?" Shirou says when suddenly she hit him on his head.

"I'm not Mordred" Saber says angry.

"my true name is Artoria Pendragon" Saber says while looking at him.

"what about you" Shirou ask him.

Archer looked at them. "I'm not going to tell my true name plus I don't remember anything about my past because my master make a mistake " Archer says while looking at them.

"is not my fault the you don't remember about you past" Rin says angry.

He looks at her and saw she was already tired. "Sakura is better if you go to sleep" Future Trunks says.

"the room is over there" Shirou says when they're walked over there.

They're walked inside the room when she laid down on the bed when he looked at her. "are you sure the is safe here" Future Trunks ask her.

"yes everything is going to be okay" Sakura replied.

"good night" Sakura says.

"good night" Future Trunks replied when he saw she was already sleeping when he walked into the window and sat down when he was looking around.

"good thing they was able to have a better life after defeating them" Future Trunks says when he grabbed his sword.

"I wonder if the holy grail would be able to grant my wish" Future Trunks says while looking into the sky when he saw the Archer was jumping in another room.

In the dining room when Rin looked at them. "so what are you going to do" Rin ask him.

"I don't know…I'm not going to hurt Sakura" Shirou says.

"I know the Trunks is you idol too" Rin says.

"he is one of the reasons you wanted to be the hero of justice…right" Rin ask him.

"yes it was him and Kiritsugu" Shirou says.

"what? Are you planning to fight him" Shirou ask her.

"no…he is strong but Archer have a chance against him" Rin says.

"sabers servant are weak against archer servants" Rin says.

"but no I prefer to wait and learn the identity of the other masters" Rin says.

"saber are you able to defeat him" Rin ask her.

"Trunks is good but he didn't master his sword so I have the chance to defeat him but I need to be careful from his attacks" Saber replied.

"I think is better if we have Trunks and Sakura like allies instead of enemies" Saber says when they're nodded at her.

He was going to say something but suddenly her a started to growl. "you're still hungry" Shirou says surprised when she nodded at him.

"next time I'm going to make the same amount as Trunks so you don't get hungry" Shirou says.

"I'm going to my house and get all my stuff I decided to stay here" Rin says when he was going to say something but she left the house.

He stood up and looked at her. "I'm going to cook the food right now" Shirou says.

"I'm going to help you" Saber replied when she walked beside him and walked into the kitchen.

Future Trunks dream

He opened his eyes when he was looking around and saw he was in a unknown location when he felt the he was shorter than before.

He looked himself and saw he was a little boy. "what is going on" Future Trunks says.

He turned around and saw a younger version of herself. "Sakura" Future Trunks says when he saw the old man was dragging her in another direction.

He quickly ran and tried to stop but nothing happen as he continued to follow them when he opened the door and saw a dark hallway. "Sakura!" Future Trunks screamed when suddenly he fell down into the floor.

He started to heard screams of pain as he was looking around and wasn't able to find her when suddenly everything turned dark.

Sakura dream

She opened her eyes when she saw the Fuyuki city was destroy when she looked around and saw a old sign when she read it. "West City" Sakura says when she saw a younger Trunks and Gohan training with each other.

She was getting closer at them. "so this is West City" Sakura says when she saw they're stop fighting against each other when she slowly walked near them.

"Gohan I want to help you fight against the Androids" Future Trunks says.

He looked at him. "Trunks if you want to help me you need to learn how to transform into super saiyan" Future Gohan says when suddenly she hear multiple explosions.

Future Gohan looked at him. "stay here" Future Gohan says when he quickly left when Future Trunks looked in the sky.

"Gohan…next time I'm going to help you defeat the androids" Future Trunks says when suddenly everything turned dark.

Sakura dream ends

She woke up and saw he was sleeping on his sofa. "so that was a memory of Trunks" Sakura says when she turned around and closed her eyes as she fell down to sleep.

Next day

She woke up and saw the Future Trunks was already awake. "good morning Sakura" Future Trunks says.

"good morning" Sakura replied when she hear somebody knocking the door multiple times when she opened and saw it was Rin.

"Sakura are you planning to go to school" Rin ask her.

"yes" Sakura replied.

"make sure the other classmate doesn't see Trunks" Rin says.

"if somebody saw him they're would be able to identify him" Rin says when she nodded at him.

She walked at him as she was looking at him. "Trunks do you best to hide you presence because a lot of people knows about you" Rin says when he nodded at her.

"goodbye" Rin says.

"goodbye" Sakura replied when she saw the Rin already left the room.

"Trunks let's go to school" Sakura says when suddenly he turned invisible when he started to follow her when he saw the Saber was following Shirou.

"Saber I'm going to be okay" Shirou says.

"no the other servants are going to go too so I'm going to do the same thing" Saber says.

"okay just hide you presence" Shirou says when suddenly she turned invisible.

He walked beside her. "Sakura what kind of wish you're going to ask the holy grail" Shirou ask her.

She looks down. "I don't know…what about you" Sakura ask him.

"I want to be a hero of justice" Shirou says when she nodded at him when they're walked into the school.

Three hours later

Homurahara Academy

Roof

Future Trunks sat down and looked around. "is a good thing the my mother was able to help them" Future Trunks thought when he turned on and saw the Saber was already over there.

He quickly stood up and grabbed his sword. "I didn't come here to fight you" Saber says when he put his sword away.

She sat down beside him. "I heard is not you first time participating the holy Grail war" Trunks says.

"yes this is my second time participating in this holy Grail war" Saber says.

"my previous master forced me to destroy the holy grail that why I came again so I would be able to ask for the wish" Saber says.

"what kind of wish you're going to ask" Future Trunks says.

"I'm going to wish the I never pulled Excalibur so somebody would be able to become King" Saber says.

"what about you" Saber ask him.

"my wish is to eliminate the androids and Doctor Gero from this timeline so Gohan and the others would be alive" Future Trunks says when he continued to observe the new view of the city.

One hour later

Rin walked into the roof when she saw the two Sabers was talking to each other when she turned around and saw him. "did you find the other masters" Rin ask him.

"I wasn't able to find the master of Lancer but I found another servant" Archer says.

"Caster" Archer says.

"good but don't attack her yet I want you to find more information about the master and maybe find her true name so we can eliminate them faster" Rin says when he nodded at her.

"what about them" Archer says.

"is better to keep them as allies" Rin says.

"we don't know nothing about the other servants so is better to have allies" Rin says when he nodded at her.

"I'm going to continue to look for the other servants" Archer says when he left as she turned around and saw the Shirou and Sakura was already there.

"Rin you forgot you lunch" Shirou says while giving her a lunch box.

"thank you" Rin replied when they're walked over there when Sakura give Future Trunks a lunch box.

"thank you" Future Trunks says when Saber was already eating her lunch box.

Rin was looking at them. "Shirou and Sakura…I was thinking the we should look around the town to look for the other servants" Rin says.

"yes is a good idea" Shirou replied.

"what if we was able to find another servant" Sakura says.

"it depends the best option is to gain information about the servant so we be able to find a weakness but the other option is to fight him" Rin says.

"the easy way to eliminate a servant is by killing the master so you two need to take care of you master" Rin says while looking at then when they'll nodded at her.

"let's continued planning" Rin says when they're walked to talk.

One hour later

Future Trunks dream

He suddenly stood up when he hear a loud voice screaming when he quickly turned around. "Sakura!" Future Trunks screamed but she didn't replied back.

He looked himself and saw he was little boy again. "what kind of dream is this" Future Trunks says when he hear the screams was getting louder.

He looked at himself and saw his hand shaking. "calm down…I need to find her" Future Trunks says when he walks backwards and step on something squishy.

He moved his feet and saw a strange and disgusting worm as the worm tried to jump at him but he quickly threw it into the wall. "what the hell was that" Future Trunks says when he saw the disgusting worm.

He started to hear help voice as every second was screaming even louder than before. "what is going on" Future Trunks says.

He started to laugh when he stop and looked at him. "Trunks…he looks like a worthy opponent to release my full power" Gilgamesh says.

"he is going to be the first servant to witness my full power" Gilgamesh says with a cocky smile on his face.

"are you strong enough to defeat him" Kirei says when suddenly he stood up and mocked his hand when multiple portal appeared around him.

"Don't you dare to question my power!" Gilgamesh screamed at him.

"I know I would be able to kill him" Gilgamesh says when he nodded at him.

He moved his hand and suddenly the portals disappeared. "call me if something interesting happens" Gilgamesh says while walking away.

"Saber the King of Knights….you're going to be mine" Gilgamesh thought.
