Author's Note: Hello, On this website, my name is Mark Tarr. This is my first fanfiction that I am writing, so it might suck. Nonetheless, I will do my best to make it as good as possible. This is a crossover between Fate/Stay Night, The Persona Games, Duarara!, Assassination Classroom, And Danganronpa. A bizarre combination, obviously. If I mess up any of the characters, I apologize ahead of time, and I will pray and work to improve for future stories. I don't own any of franchises that I am using.

Prologue: End of One War

Kiritsugu Emiya's Point Of View

"I am finally going to do it. I will finally save the world. After all these years," Kiritsugu thought to himself. He was now standing on Alimango Island, where he was raised. He saw the beaches and the trees, the fishing village and its inhabitants that he had left behind so long ago. The sky turned dark, and the village and its people had disappeared. "You made it!" said a excited feminine voice.

Then, appearing right in front of him, was his wife Irisviel. "You did it honey, you won. Now you can grant our wish,"she said cheerfully. Her pale skin, long white hair, and clear red eyes, along with white dress she had used for years on her lovely figure, brought back his pleasant memories he had with her. And the price he had to pay to gain the Grail.

"My wife is dead,"he responded bitterly.

"Correct,I am the Holy Grail," she told him without any hesitation. "I took this form to tell you, that the only way to save the world, is to do it in the only way you know," she said with a smile on her face.

Then, he was shown in his mind a violent vision of the results of his wish. There were images of wars and battles across the world, cities on fire, all the people who would have to die, screaming for help! Then, he saw the world was unified . However, to keep this new peace, many more people would have to be sacrificed for trying to rebel against the tyrant ruling the world: Himself. While being shown this , Kiritsugu had a look of horror on his face, his knees forcing him to kneel, and beginning to shed tears. "To save the many, you kill the few, the many will then become the few themselves to keep the world safe. This is the miracle I can give to you." The Grail told him truthfully.

"This isn't what I want!" Kiritsugu yelled. He thought back to the way he saved others, and realized this Is the outcome he created through his ideals. He then began to think of a way to avoid this series of events "I must destroy the Holy Grail!" he decided to himself

The Grail knew what his thoughts were. She said " If you try that, I will grant the wish to your enemy," and so, she showed him another vision. He saw Fuyuki consumed by black mud, the city burning in flames, and children suffering at the hands of his greatest enemy : Kirei Kotomine. "There will be blood on your hands no matter what you do,"The Holy Grail announced to him.

"I have to make a different wish!" he decided. "But what should it be?" he asked himself.

He then remembered his longtime assistant : Maiya Hisau. How he saved her from her captors, and gave her a new life with him. He remembered how it felt good to personally save someone. Even so, her purpose was to die for him. He now realized that the only thing he wanted now was peace with his family, an end to him causing endless bloodshed, and to save people personally. He just needed to make sure his wish would kill the least amount of people…it was what he always did after all.

The Holy Grail then said "So, you have a new Wish now?" she said. Kiritsugu nodded. "Before you make it, the last servants need to go. But first, I'll show you what comes with your wish," The Holy Grail told him. So Kiritsugu saw the horrors that were to come when he made his new wish.

Destroyed Parking Lot

Kirei Kotomine's Point of View

Kirei was getting up from the floor. He felt pain from his duel with Kiritsugu, but still felt empty inside. "I need to defeat Kiritsugu, take the Holy Grail, and find my purpose for living!" Kirei yelled to himself, in his mind. Before he could completely stand up, he felt a gun aimed at the back of his neck.

"What are you doing? Don't you want your wish?" Kirei yelled in confusion. "I'm wishing for something different now, and I can't let you interfere," Kiritsugu told Kirei angrily.

"What ?!" Kirei asked, confused and angry. Before he could get an answer, Kiritsugu pulled the trigger. Kirei fell back down and began to choke, as blood started coming out of his neck.

Kiritsugu then began to walk away, leaving Kirei to die. "This is it. I have wasted my life trying to answer what would fill the emptiness in my heart. A fitting end," Kirei thought to himself, as his mind became blank and his eyes closed.

Fuyuki City Hall

Saber's Point Of View

Saber had just defeated Berserker and had now entered the location of the Holy Grail. She realized what her failure was as king. She didn't understand what her people wanted because she didn't understand what she wanted. What she wanted now was to rule as a adult and not a scared girl.

As she walked closer to the Grail, Archer materialized above her, standing on the top of a rail. "It's about time you arrived. I was getting bored. However, before we begin our final duel, I have a proposal," Gilgamesh said. He then looked at her with desire in his red, snake-like eyes. "Lay down your sword and become my wife!" He proclaimed.

Those words angered Saber, who yelled "I will kill you before that happens!"

Gilgamesh laughed then, opening his Gate Of Babylon to prepare for the fight. "Then I will make you suffer before you become mine!" he the swords started to come out of Archer's gate, Saber dodged the attacks.

Just then, Kiritsugu arrived. He then said "With my Command Seal, I order my servant, Saber, to kill Archer with your Noble Phantasm !"

Saber's free will was now controlled by Kiritsugu, preparing her sword with golden energy. While she viewed this as dishonorable , as she judged many of Kiritsugu's past actions and orders, she was to glad that he gave her this order.

"Excalibur!" she yelled, striking Archer with her beam of light quickly. He launched several swords from his Gate of Babylon to block her attack, but they were consumed by Saber's Noble Phantasm. Gilgamesh was struck in his golden armored chest, blasting a bloody hole through his body.

When the attack ended, Archer fell down with a clang on the velvet floor, dying with a smile on his face. "This dream has ended," he said quietly to himself, before becoming golden dust.

Kiritsugu now walked towards the Grail, as did Saber. "Goodbye, Kiritsugu," she said angrily, glad she was finally leaving him.

"I wish to redo the reign in Britain, as an adult, and with proper knowledge and wisdom," Saber declared. She then began to disappear, but would eventually find that her wish would come at a price.

Kiritsugu Emiya's Point Of View

Kiritsugu now made his own wish. "My wish is to raise my family in today, I will end the cycle of bloodshed that I've created. I will have my wife back, and my daughter will come live with me. And…I want to save someone, one last time," he said with sadness in his voice, knowing that mankind will never know peace.

"Then it is time for the sacrifice," The Holy Grail declared, with a deep, haunting voice. The moment Kiritsugu dreaded was here. He was now being consumed by red and black mud, which continued to spread with extreme heat. It quickly covered the entire city of Fuyuki. Once the mud passed, Kiritsugu saw that all of Fuyuki was in flames!

Kiritsugu shed tears, knowing this was his fault. He then began to run across Fuyuki, trying to find someone, anyone he could save!

Then, Kiritsugu saw a sliver of glowing, white hair, coming out of a collapsed mansion. He then realized that it was the Einzbern Mansion! Then his daughter, Illyasviel Von Einzbern ,appeared from a stone she pushed away from herself.

Kiritsugu ran towards her, and hugged her. "Papa!" she yelled happily. She then asked "Where are we? One second I was learning magic from Grandpa, then the mansion collapsed and I'm here with you now."She then saw her father's tears.

Then 2 Einzbern homunculi maids came out of the burning mansion. They both looked very angry. "Leysritt And Sella, you're alive!"Illyasviel yelled with relief. "What happened!?" Sella asked with anger. "Lord Jubstacheit is dead! Did you bring us here?" Leysritt asked, a tired look on her stoic face.

Before they could say anything else, Irisviel came towards them.

Irisviel Von Einzbern's Point Of View

"I'm alive," she thought to herself with confusion. "Kiritsugu, how am I here?" Irisviel asked as she approached him.

Kiritsugu ran up and hugged Irisviel. Irisviel smiled and hugged him back.

"I choose a different wish," he said simply. "The World wasn't going to get peace with my original wish," Kiritsugu explained with a sigh.

"I think I remember that," Irisviel said while thinking back. "How?" Kiritsugu asked with surprise on his face and in his voice. "The Holy Grail gave me the memories it had with you while taking my form," Irisviel explained.

"You betrayed the Einzbern's!" yelled Sella. Illyasviel looks at her servants with anger. " We only serve lady Illyasviel, not the Eiznbern family!" declared Leysritt with finality.

Before anything else could be said, they heard breathing from underneath a piece of stone. Kiritsugu ran over to it and began to frantically place the stone out of the way. When he cleared it, he saw a young boy, with red hair and golden-brown eyes. He had a look of dread on his face.

"I've saved someone!" Kiritsugu yelled with relief. Irisviel came over to them both and began to rub the scorch marks off the young boy's face. "I don't know if he can survive much longer," Irisviel told Kiritsugu with worry. Then, Kiritsugu pulled Excalibur's scabbard out of his body and placed it in the boy's.

Illyasviel and her two maids came to see the boy. "Do I get a new brother!?" Illyasviel asked with excitement. "If he wants to live with us," Kiritsugu said.

Irisviel then bent down to Kiritsugu and told him "There will be another Holy Grail War." Kiritsugu look shocked and heartbroken. He then asked "Where?" Irisviel responded with "Ikebukuro."

I made changes to the scene with Kiritsugu in the Holy Grail. I didn't want to just copy the scene from the anime, and wanted to take a different approach to it. I'm planning on have Artoria coming back as a Lancer servant, but you will have to wait and see what her new history and new wish will be. Expect another prologue to come soon. Until then, see you all later.
