Park
In the park when Illyasviel was looking at him. "Berserker! I want you to kill them" Illyasviel says with a smile on her face.
Shirou saw the small girl. "what…don't tell me the little girl is participating in this holy grail" Shirou thought.
"Shirou! You need to focus on the battle!" Saber says as she prepares to fight him when Berserker quickly ran at them.
Sakura looked at him. "Trunks! Tried to work with Saber!" Sakura says.
Rin looked at him. "I want you to support them" Rin says when he nodded at her as he quickly ran in a different direction.
He grabbed his sword and ran beside her. "Saber… I know a way to eliminate him" Future Trunks says while holding his sword.
"what is you plan" Saber replied when he quickly whisper his plan when she nodded at him.
Berserker ran at him and slammed his heavy sword against them causing a massive crater when Saber and Future Trunks was able to dodge it as he quickly slashed his sword near his shoulder.
"so Berserker have a tough skin" Future Trunks though when he quickly caught his sword causing multiple shock waves when Berserker tried to push the sword against him when the ground started to shatter into little pieces and a crater started to appear below him.
"Saber! Attack him right now!" Future Trunks screamed at him when she quickly pushed her sword against him when he quickly push her away from him.
Shirou moved his hand and created two small blade. "I'm not going to stand her and do nothing" Shirou thought when Rin quickly stop him.
"are you crazy! You're going to get yourself kill" Rin says.
"if you want to help her first make a plan instead attacking like a wild beast" Rin says as she grabbed multiple gems and threw at him causing multiple explosions when the smoke disappeared and saw he didn't have any damage.
Future Trunks appeared next to him and quickly uppercut him into his stomach as he continued to punch him when he slammed his fist causing him to gasp as he grabbed his arm and threw him into the boulder.
"Saber! Do it now!" Future Trunks screamed at him when she moved her sword as the sword was already visible when she started to release more of her power when the sword started to collect energy.
He saw the massive energy. "Saber! Kill him!" Shirou screamed at her.
"Excalibur!" Saber screamed as she slashed her sword caused the energy blast to slash him into two pieces.
She put her sword down and saw he was already death. "yes w-" Saber stop and saw the small girl laughing.
"you all think the one attack is going to kill him" Illyasviel says when suddenly Hercules stood up as he was staring at them.
Future Trunks looked at him. "I never expected to meet another powerful warrior" Future Trunks says as he started to release more of his power when he appeared next to him and slammed his fist into his face causing him to bleed.
Sakura saw her command seal was getting brighter than before. "this is strange" Sakura though when she turned around and saw the Future Trunks was still fighting against him.
He moved his hand and started to gather energy around his sword. "Sword of Hope!" Future Trunks screamed as he slammed his energy blast against him causing a massive explosion when the smoke disappeared and saw him in the ground.
He turned around and looked at her. "we already won!" Future Trunks says when suddenly he quickly turned around and saw a lot of smoke when he saw Berserker again.
"how many times we need to kill him" Future Trunks though as he quickly blocked his punch causing multiple shock waves when he looked at him.
"what kind of servant are you!" Future Trunks says while blocking his punches causing multiple shock waves.
She looked at him and saw he was able to fight against her servant. "no wonder you was able to fight him" Illyasviel says.
"you real name is Trunks Brief" Illyasviel says while looking at him when he didn't say nothing.
"Hercules! I want you to kill his master!" Illyasviel screamed at him when he quickly started to ran at her when he appeared next to him and quickly slammed his fist into his stomach causing him to gasp.
Rin looked at them. "Saber and Shirou tried to protect Sakura" Rin screamed at them.
"Saber let's tried to protect her" Shirou says.
"we can't loss Trunks…he is the only one the is able to defeat Hercules" Rin though.
Future Trunks quickly slashed his head causing him to fell down when he was going to say something but suddenly he stood up started to release more of his power. "how many times I need to kill you!" Future Trunks screamed.
He quickly slash him into little pieces as he moved his hand. "burning attack!" Future Trunks screamed throwing the massive energy blast against him causing a massive explosion when the smoke disappeared and saw he was already gone.
He turned around and suddenly a dark cloud started to appear when suddenly Hercules appeared again. "what! You already died four times!" Future Trunks screamed at him.
She looked at him. "I need to be careful…it would be dangerous if he transform into super saiyan" Illyasviel though.
Future Trunks blocked his punch causing multiple shock waves. "that it! I'm not going to hold back!" Future Trunks screamed when he started to release more of his power as his aura was moving more wild than before when a light appeared causing to transform into super saiyan.
Sakura saw her command seal was getting more bright when she felt something weird on her body. "what is going on..why my energy is getting weaker than before" Sakura though when she saw Future Trunks was already in his super saiyan.
Future Trunks quickly slashed him into little pieces as he moved his hand and slash him into little pieces. "this time I'm going to end you" Future Trunks screamed while throwing the energy blast against him causing a massive explosion.
The smoke disappeared when he put down his sword when smoke started to appeared when he looked at him. "so he still alive" Future Trunks says when he saw the Berserker was able to restore his body.
Illyasviel looked at him. "they already removed five lives of Berserker" Illyasviel though.
Future Trunks quickly slammed his fist and uppercut him into his stomach causing him to cough as he grabbed his hand and started to swing him around. "I'm not going to let him kill her" Future Trunks though as he threw him into the sky.
He moved his hand and started to charge his attack. "final flash!" Future Trunks screamed throwing the massive energy blast against him causing a massive explosion.
He saw the smoke was gone but suddenly he appeared again. "what…we already kill him…six times" Future Trunks thought.
Sakura saw the Future Trunks was still fighting against him when she was having a hard time breathing when she slowly fell down on her knees and spit blood from her mouth as Shirou quickly ran at her.
He saw she was already tired. "Sakura…I think you need to rest" Shirou says.
Illyasviel turned around and saw the Sakura was already in the floor as she started to laugh. "It looks the you master is not strong enough to sustain you power" Illyasviel says while looking at him.
"what are you talking about!" Future Trunks screamed at her.
"you're a strong servant but you're not really that smart" Illyasviel says.
"the master are responsible of giving enough energy to the servant so they would be able to have a physical body" Illyasviel says.
"it looks the you're the same as my Berserker" Illyasviel says.
"the more power you used the more energy she need to used so you would be able to have a physical body" Illyasviel says.
Future Trunks saw she was already and her command seals was brighter than before as he returned in his base form and saw she started to breath normally. "it was fun to play with you two but we need to leave" Illyasviel says.
"Berserker let's go home" Illyasviel says when he app next to her as they're walked away from the park.
He quickly ran at her when he saw she was already tired. "Sakura let me carry you" Future Trunks says while carrying her on his arm.
Rin walked beside him. "she is going to be okay" Rin says.
"she needs to regain some of her mana back" Rin says when he nodded at her.
"Rin I think is better if we leave right now" Shirou says when she nodded at her when they're walked back home.
Ten minutes later
Shirou residence
He walked inside the room when she put her on the bed. "Sakura I want you to sleep so you would be able to regain some of you energy back" Future Trunks says when she nodded at him when she closed her eyes and fell down to sleep.
He left the room and saw the Rin was waiting for him as she walked at him. "it looks when you transform into super saiyan she loss a lot of energy" Rin says.
"yes but I need to make sure it don't happen again" Future Trunks says.
"I think being a servant is restraining most of my power" Future Trunks says.
She looked at him. "if you want to hear my advice it would be better if you only used super saiyan to defeat you opponent" Rin says.
"goodbye I need to talk with Archer" Rin says as she left the house when Future Trunks walked inside the room and saw she was still sleeping.
Ten minutes later
He was removing the sweat from his forehead when he walked into the restroom when he was in shock when he saw the Saber was taking a bath as he quickly turned around. "I'm sorry I didn't know you was taking a bath" Shirou says embarrassed.
She looked at him. "is okay….I'm going to finish soon so you would be able to take a bath" Saber says.
"Saber I was thinking the tomorrow we can train together so we can improve our team work" Shirou says.
"sounds like a good idea" Saber says when he nodded at her.
"Saber…take you time bathing…I think you deserve to relax after fighting with Berserker" Shirou says.
"Thank you Shirou" Saber says when he quickly left the restroom when he almost crash against Rin.
She looked at him and saw he was embarrassed. "what? Did something happen" Rin ask him.
"nothing" Shirou replied when he quickly walked into his room.
She walked into her room and saw the Archer was already there. "Archer did you find the master of Lancer" Rin ask him.
"no" Archer replied.
"it looks the master of Lancer is good at hiding" Archer says when she sat down near him.
"I was hoping the we be able to eliminate him" Rin says.
"what about Caster?" Archer ask her.
"is to early to attack Caster and most likely she is ready to defend her own territory" Rin says.
"right now I only worried about Berserker" Rin says.
"we was able to kill him six times but somehow he was able to come back" Rin says.
"you want me to focus on finding his real name" Archer ask her.
"no it would be risky if you go to the territory of Illyasviel" Rin says.
"what about eliminating you teammates" Archer ask her.
"no...we need they help so we have a higher chance to defeat Berserker" Rin says when he nodded at her.
"good I'm going to rest so don't do anything dangerous" Rin says when she walked into her room while Archer left the house.
One hour later

He sat down near her bed when he saw she was still sleeping. "the holy grail…I'm going to make sure to win this war so I would be able to change this timeline" Future Trunks says as he continued to observe her.
Sakura dream
She opened her eyes when she was looking around and saw a demolish building when she stood up and saw Trunks when he was a teenager.
She was getting closer at him when suddenly she hear a noise and saw a tall man. "Gohan!" Future Trunks screamed with excitement.
Future Gohan looked at him. "Trunks I already told you the you need to stop following me" Future Gohan says.
"I want to learn how to fight so I would be able to help you" Future Trunks says.
He was looking at him and saw he was serious. "fine I'm going to train you but I'm going to focus on pushing you limits so you would be able to transform into super saiyan" Future Gohan says
"don't worry I'm not going to disappoint you" Future Trunks says when suddenly everything turned dark.
Sakura dreams end
She opened her eyes and saw he was already sleeping. "another dream about Trunks past" Sakura says when she walked into the kitchen and saw the Saber was there.
"what are you doing here" Sakura ask her.
"I was going to make something to eat" Saber says.
"is okay I can make you something to eat" Sakura says.
"are you sure? If you want I can help you" Saber says when she nodded at her when she walked beside her and started to help her cook the food.
Sakura room
Future Trunks dream
He opened his eyes when he was falling as he quickly turned around and saw he wasn't able to fly as he crashed to the pit when he moved his hand and saw a lot of worms.
"what kind of place is this" Future Trunks says when he started to looked around when he saw the Sakura was near him as he was getting closer and saw the worms was trying to get inside her body.
He saw the Sakura didn't have any emotions on her eyes as he walked beside her and tried to touch her arm but suddenly he wasn't able to touch her hand.
"so is another dream" Future Trunks says when he was having a hard time looking at her.
He saw she was having a hard time breathing when Future Trunks stared at her. "Sakura…you don't deserve this kind of life" Future Trunks says while looking at her emotionless eyes.
He turned around and saw the old man laughing. "the grandfather of Sakura" Future Trunks though when he quickly push the worms away from him.
He jumped near him and stared at his eyes when he saw he didn't have any mercy on his eyes. "if the same way as the androids" Future Trunks though.
"Sakura…you're going to be the key of gaining the holy grail" Zouken says as he started to laugh when suddenly everything turned dark.
Future Trunks dreams end
He opened his eyes and saw she was still sleeping as he stared at her. "I know this dream was a memory from her childhood but…I don't think is right for me to ask her" Future Trunks thought when he opened his window and saw a strange dark shadow.
He stared at him and felt the dark aura as he moved his hand but suddenly he disappear. "what the hell was that" Future Trunks thought.
He turned around and saw she was awake. "Trunks…are you okay" Sakura says sleepy.
"yes…I just saw something weird" Future Trunks says when he remember the strange dark shadow.
"something weird" Sakura says confused.
"I saw a dark shadow staring at the house" Future Trunks says.
She was going to say something but he interrupts her. "don't worry I'm going to protect you" Future Trunks says.
"yes I know you would be able to protect me" Sakura says.
He looked at her. "but I wonder if the dark shadow is a servant" Future Trunks says.
"I don't know but I heard a lot of rumors the some people are getting disappeared around the city" Sakura says.
"so people are getting disappeared around the city…next time I'm going to fight him" Future Trunks says when she nodded at him.
"I think is better if you stay he tomorrow I want you to rest more so you would be able to have enough mana for the next battle" Future Trunks says.
"don't worry I'm going to stay here…I need to regain most of my mana" Sakura says.
"yes..it was my fault the you lost a lot of you energy" Future Trunks says.
"is not you fault it was my fault for not having a lot of mana" Sakura says.
"I was thinking the you should used super saiyan only when you are going to eliminate the enemy" Sakura says.
"yes is the only way to win the holy grail war" Future Trunks says when she nodded at him.
She laid down on her bed. "Trunks can you tell me more about you life" Sakura ask him.
"I thought you already know" Future Trunks says when he show her the history book.
"yes but still I feel the something is missing" Sakura says.
"I mean this book told most of my life except my adventure from the past" Future Trunks says.
"wait…you went to the past" Sakura says in shock.
"I heard the is impossible to travel time" Sakura says in shock.
"the strange…maybe my mother destroy the time machine so other people wouldn't be able to used it" Future Trunks says.
"can you tell me you adventure from the past" Sakura ask him when he nodded at her when he started to tell his past.

"yes I think so but most likely the other timeline is more advanced" Future Trunks says.
She looks down. "so the means in another timeline they another me" Sakura ask him when he nodded at her.
"I wonder if she have the same experience as me" Sakura says while looking down.
He was going to say something but she interrupts him. "Trunks if you want we can go to the museum" Sakura says.
"museum" Future Trunks says.
"yes it was created to show respect to Bulma Briefs" Sakura replied.
"sounds good but I don't want to be invisible" Future Trunks replied
"yes is fine" Sakura replied when she laid down on her bed.
"goodnight" Sakura says.
"goodnight" Future Trunks replied when he turned around and kept his sword near him.
