Kakashi's Son

Prologue

Harry James Potter, future saviour of the wizarding world, future vanquisher of the Dark Lord lay sleeping in Lily Potter's arms. She stroked a strand of his unusual silver-grey hair. She and James had been most confused when he was born with silver-grey hair, instead of red or black, but had taken it in their stride. It hadn't taken Lily long to remember the only other person she had met who had the exact same hair colour. Him. Kakashi Hatake.

She had tried very hard to forget her ninja life. Her father had died on a mission, and her mother had been grief-ridden. She had found a way to leave Konoha, and in fact, all of the Elemental Nations, to the Outside World. She had left Lily, known as Yuri back then, alone in Konoha and gone to a place called England, changing her name to Olivia Smith, purposely choosing a common surname. She had left Lily with information on how to join her, if she ever wanted to, and once a year she gave Lily a letter, strangely sent by a beautiful tawny owl. She had married a man called Peter Evans, and had a daughter named Petunia.

Lily would have gone with her earlier, but a silver-grey haired boy had unknowingly made her stay. Kakashi Hatake. She had been fascinated by him. They had grown close, but after his teammates, Obito Uchiha and Rin Nohara had died, he became distant, having no time for her. He then became an ANBU and Lily had left, heartbroken. He barely acknowledged her and she couldn't stand it. She had no idea that it was hurting Kakashi as well.

When Lily left Konoha she had been transformed into a young six-year-old. Thoroughly annoyed she quickly found her mother's house, as she had landed on their street. Her mother had been shocked, then laughed at her daughter's fate. She welcomed Lily back to the family, meddling with the family's minds, making it seem like she had been born around the same time as Petunia.

Her chakra had been modified, much like her mother's had been. She said it was a side effect of the jutsu that bought them here. She had hit 11 for the second time and received a Hogwarts acceptance letter and, after about 10 minutes of laughing at the name, she had accepted. There she met many, Severus Snape, Peter Pettigrew, Remus Lupin, Sirius Black and James Potter.

And after years of denying him dates she finally accepted one.

And she fell for him.

But it didn't go that smoothly afterwards.

They left the magic school and moved in together. But Lily was homesick, and her mind was plagued by certain Silver-grey haired Shinobi. So when she was visiting her mother and her mother admitted to knowing a jutsu that temporarily transported one to the Elemental Nations she had used it.

She had landed in her old house in Konoha. To say Kakashi was shocked was an understatement. He had been grief-ridden after she left. He had lost Rin and Obito and hadn't wanted to lose Yuri either, so had had become distant, hardly seeing her. He had hated it. And then she had gone missing and it had gotten worse.

He had been sitting on her bed when she appeared. It was the anniversary of when they had first met, and every year he came to her house and spoke to her. She was his weakness, though barely anyone knew it. He had been sitting there half-an-hour in silence. Then Yuri had appeared out of nowhere.

Yuri had made him swear to secrecy about her visit. He had half-heartedly agreed. She then explained what had happened, minus the magic and a certain James Potter. She also mentioned she could only stay for a month. He had been sad, but it was better than nothing.

They grew close over the month, and Konoha was surprised to see him in a happier, cheerier mood than usual, Gai had asked him about why he had decided to embrace his 'flames of youth' and the Hokage watched him in silent contemplation.

When Yuri left at the end of the month she was pregnant.

Kakashi grew reclusive and detached again, more than he was before, leaving the village in a state of confusion. But he slowly came back to normal with the help of his friends.
