By the time the Fifth Holy Grail War takes place, Naruto is a seasoned Kunoichi and attends the orphan Emiya Shirou's high school. The Night Lancer attacks, both teens are pulled into a secret war that they had no idea of, nor want to participate in. (Minato/Kushina, one sided Gil/Female Naruto Shirou/Saber and Rin/Archer)

Summary: After fleeing Konoha, Naruto and her mother Kushina find themselves thrust into a secret war. With her Servant Assassin by her side, Naruto must somehow survive the Holy Grail War and Gilgamesh's attention.

(Prologue: Fleeing Konoha)

Kushina leaned against the cave wall as she watched the Kyuubi's rampage. His behavior really scared her. For years she had been his container and every time she had needed help his chakra, and advice, had been at her disposal. Seeing him act so insane when he was normally a calm, cheerful, gentle, playful giant was unnerving.

She knew that she should have died when her friend was ripped from her seal, but apparently, Kyuubi had set a fail-safe in place to protect her from death. Kushina could sense a tail's worth of his chakra flowing in her Tenketsu, keeping her alive. How her friend had done it she didn't know. But she knew that she was grateful to him for managing it.

Kushina knew her husband was out there with their daughter, she hoped they would both be alive at the end. "Please come back to me Minato…" She whispered. She didn't want her daughter to be without her father! "Please…"

Suddenly, everything was silent, and Kushina returned her gaze to the village. Kyuubi was nowhere to be found, was he gone? Silly question, he had to be. Sealed, sealed into her baby daughter…

A tall blond man appeared, staggering towards her. Kushina gasped. "Minato! Are you ok?" She raced to his side. Held tightly in his arms was a tiny infant girl. "How is Naruto-chan?"

"She… She's …fine… Kushina-chan…" Minato stumbled, nearly falling to his knees.

"But what about you…?" Kushina asked, "Minato I don't want to be a single mother!"

"I'm sorry; I won't be able to be with you…" Minato started coughing up blood; He let Kushina help him to the cave. He collapsed at the mouth of the cave and Kushina helped him sit against the wall. "I've told Sarutobi-sama that I want Naruto-chan to be celebrated as the hero of tonight, but I doubt that will happen…" he brought one of his hands to his mouth, as he coughed harder, and to wipe the blood away.

"Why not Minato?" Kushina asked. "What do you want me to do?" She watched in despair as the color and life drained from her husband's face.

Minato pushed their tiny daughter into his wife's arms. "Her name is Uzumaki-Namikaze Naruto you know…" He struggled to get out. "Sandaime-sama told me that after this night, her name will be Uzumaki Naruto if you stay, you will lose our daughter, and she will lose her name, her history, her… our clan…" with each word, Minato's voice got fainter and fainter.

"Why? Why would he strip her of her name?" Kushina asked.

"Supposedly to protect her from my enemies…" Minato answered. "Sarutobi… plans to take Naruto from you and place her in the orphanage… Promise me something…"

"Anything Minato…" Kushina whispered with tears in her eyes. "What is it you want from me?"

"If you stay you will lose everything," Minato told her. "Sarutobi plans to announce to the village that Naruto is the Jinjuuriki, we both know that the civilians and the less educated ninja will believe that she is Kyuubi-kun… Take Naruto-chan, and flee… Run Kushina and don't return until you feel that it is safe for her… But more than that… Make sure that she knows who she is and that I love her more than anything… Tell her that I died so that she could live…"

"Minato…" Kushina breathed, tears streaming down her cheeks.

"Train her, Aisai… [1] Train her to be the best Kunoichi, I am naming her my successor, Sarutobi-sama knows and approves…" Minato leaned forward and weakly pressed his lips to hers in one last kiss. "Only return when you feel it is safe… Run Kushina, run…" His bright blue eyes went dark as he died.

"I will do as you wish, Yondaime-sama…" Kushina whispered, her voice trembling and cracking. "Goodbye Minato, I love you…" She turned, fleeing the village, taking her daughter with her.
