Kushina Uzumaki was lying in a bed with two small bundles in her arms. One had a beautiful blond haired baby with blue eyes and whiskers marks, who was named Naruto and the other one a jet black haired one with bright green eyes also with whisker marks, who was named Hari. She was very happy to finally hold her babies in her arms after a very long and exhausting birth. She was a bit angry at Minato who left before he could see his children, but she understood that there was an emergency that needed his immediate attention.
She was watching her children with a exited smile, when suddenly a dark figure appeared out of nowhere, killing the ANBU and the midwifes. Kushina alarmed put both babies in the beds next to her and tried to stand up with no success.
-"Who are you", Kushina fearfully asked the figure
-"My name doesn't matter, but you can call me Tobi. Now let me relieve you of your burden", he said and threw a needle with paralyzing poison at her. The needle struck true and soon she was unconscious, Tobi not wasting any moment started weakening the seal on her stomach. He was almost finished, when a yellow glow engulfed Kushina's bed and a blonde man came out of it and attacked him, but he went straight through him. The blonde man not faltering at all threw a three pronged kunai at Tobi, which he dodged, and teleported to it holding a Rasengan. Tobi became intangible once again, but when he dodged the Rasengan and became tangible the blond man grabbed him and they both disappeared in a yellow light.
Kushina who was almost conscious again tried to fix the seal, but to her horror the seal was already to the point of no return. Knowing that she had a few minutes before the Kuybi was released she headed to her children and with teary eyes she hugged them. -Please forgive me for leaving you alone. I wish I could watch you grow up", she said and gathering all the chakra and strength she could she shunshined away leaving leaves and traces of red chakra behind.
Moments later a monstrous roar was heard. The Kuybi was free. When Minato and Tobi saw the Kuybi, Tobi disappeared leaving Minato alone to fight it.
Minato hirainshined to his children's room and gently grabbed both of them. He hirainshined once more and was now standing in front of the Kuybi. The Kuybi gave a mighty roar and started preparing a bijudama, however before he could finish it Minato started going through many handseals at a blurring speed. When he finished the handseals he hit the ground which cracked. A being almost as tall as Minato came out of it, emitting high levels of KI.
-"Who dares to disturb me", it said with a voice full of authority and power.
-"Shinigami-sama I am sorry to disturb you, but I want a favor from you", Minato said
-"And why should I obey the request of a mere human mortal", it said this time with an angry and challenging voice.
-"I will offer my soul in exchange", Minato said.
-"Very well Human, I will accept your offer. Now state your request".
Before Minato could respond the Kuybi fired his now fully charged its attack to the Shinigami, who negated it with a lazy flick of his scythe.
Amazed at the Shinigami's power he stated his request stuttering a bit
-"P-Please seal the Kuybi in my sons, half of it in each one".
Without answering the Shinigami pierced Minato's body with his scythe and removed his soul, which then put in his stomach. Then he turned to the Kuybi and with a scythe in his hand, he splitted it it in half. He then turned to see the children who would be hosts to the Kuybi but when he saw them, his eyes widened. He gathered the Kuybi once again and this time he splitted it in 3 equal pieces each holding the same portion of the Kuybi's soul and put one of them in Hari, the other one in Naruto and held the third one. Golden and green light erupted from the babies and when the lights settled down Shinigami gently picked up Hari
-Your Destiny is not in this world for now, but you will someday come back to your homeworld, he said with a soft almost human voice and disappeared in a swirl leaving behind a crying baby and two dead parents each one holding onto Naruto. No-one would suspect that there was missing a baby.
The Shinigami or as he was known in this world The Grim Reaper, appeared outside of a manor where Lily Potter just gave birth to a girl named Violet. Currently the only ones who knew about the birth of the child were inside the room where Lily was giving birth thus making it easier for the Grim Reaper's Plan. With a swirl he teleported into the room and with a sweep of his hand he modified the memories of the people in there, so they would think that today twins were bornand froze them until he finished what he wanted to do. He placed Hari next to his sister and started casting a spell in an unknown language which soon changed Hari's appearance to resemble that of Lily and James Potter. He then took the last piece of the Kuybi and gave it to Hari's soster Violet. A intense blue light surrounded her and when it died down whisker marks could be seen on her cheeks. With a satisfied look The Reaper left.
Once he left unbeknownst to The Reaper a woman wearing a golden dress with flaming red hair entered the room and kissed both Hari and Violet on their forehead giving Hari the gift of Magic and boosting both of their magical abilities. As soon as she left the people in the room who were frozen started moving again. They celebrated the birth of the twins, who they decided their names would be Harry and Violet, oblivious to what transpired in the room just a moment before.
One year later those twins would be known as the Twins-Who-Lived, The Saviors of the Magical World.
