A/N: Okay this is another fanfic of mine concerning that, I was bored on my Easter break so I hope you all enjoy it!

Summary: Since Genkai passed away two years ago, everyone else was called into her temple where Koenma gives shocking news and a mission to both the spirit detectives and the girls. As they found out they have kids of their own in the future that would be coming to them, two children are left with unknown father and mother so who is it?

In the Future

"Mwahahaha, so demon wills you hand over your wife to me? Or do you care what happens to your child just what I did to the detective and his friends?" said the other demon who was holding the child hostage, while the other was defending his wife, the demon would not want to give his wife to the demon at the same time. The mother who was desperate to get her child back and the only way to do it is to surrender herself.

"I'm sorry Kurama please forgive Me.," said the woman. She walked passed her husband and said to the other demon,

"Let him go, I'm here and if you want me right now I'm ready."

The women stepped closer until she heard a familiar voice,

"Mother don't do it, it's a trap!"

The mother turned her back and suddenly the demon came close to holding a dagger to kill her but Kurama stepped in and instead of killing the wife, he killed Kurama. Blood spilled in front of her and as she saw her husband begin slain she yelled,

"SAYURI! Get back and fly back to Spirit World with your brother hurry and - "

As soon, as was going to finish the demon had killed and said,

"I have finally killed those pathetic detectives and their pathetic family. Now it your turn now little girl and don't forget your twin brother."

Sayuri who had witness her parents getting killed could not move her brother who was knocked unconscious woke up. As he woke up he heard his sister crying above all that he saw his parents lying dead in the ground, rage was building up in his heart and suddenly he transform to his fox form which he never did. The demon was close to the little girl and she was still shock but as her brother charge in maximum speed closing, her eyes she yelled,

"Hiro don't!"

Suddenly she started glowing and everything went blank. The light was so bright that the demon could not see, and as the light faded, the two children disappeared.

In Spirit World

As the two reopened their eyes, they heard a voice from their right, who said,

"That damn bastard how dare he killed my parents just who hell is he? If I…I was just had reach the house…I could…I could kill that son of a bi-"

"Are even sure you could defeat that bastard for killing your parents?" Asked the voice, who was from the entrance of the door. Behind him were his wife and his fourteen-year-old daughter.

"Shut up pacifier breath!" the child answered back.

Next to him is a girl crying and what's strange was that her tears were turn into precious gems besides her was her cousin who couldn't say anything and just as her father she showed no emotion but on the inside she was crying over the death of her parents.

"M-master Koenma, why are we here?" asked Sayuri. She was still depressing about what happen and she needed answers. Her brother was by her side and asked in calm yet deadly voice,

"Now tell us, why did you bring us here? And above that why didn't you tell our parents about this murderer and what were his reasons for killing them?"

Koenma gave a deep sigh and wondering why these tragedies happen and how he knows that the entire human race would the gone.

"I see your just as your father, all of you remind me of them and-"

"Get with jack ass!" interrupted the child who has named Raizen, he was Yusuke and Keiko's son and he definitely has Yusuke's personality.

"Shut up Urameshi you have no right to insult anyone!" yelled Hina, she was the daughter of Kuwabara and Yukina, and she does have her mother's looks and her father's eyes. She and Raizen were like their fathers who always argue and in a different story; she just acts like Keiko who is also smarter then Raizen. She really is a kind and gentle girl just as her mother and in the same time, she has a fighting spirit.

The two were still bickering and Koenma could not explain until Hanabi interrupted the argument,

"Will you two stop flirting and let him talk."

The two looked at each other with death glares on their faces then turned their heads from the side.

"Why would I flirt with someone who couldn't shut up about how cool he is?" said Hina who crossed her arms not looking at the idiot to the side of her.

"And why would I flirt with someone who's so bossy?" Raizen added.

"Ahem, I hope you two are done because I have a mission you guys should do for Me.," said Koenma.

He looked at the five children then to her daughter who he nodded telling her to be in front of him with the others.

"You see, we have no clue why this criminal wants to kill your parents and were trying to figure out who he is. So what I want you all to do are go back in time to warn your parents about the danger."

"And how are we supposed to do that genius?"

"That would be my job kids.," said the fourteen-year-old girl.

She is the daughter of Koenma and Ayame, she is different from her parents and her powers were mysterious from the others. She had pink cherry blossom hair which were up to her knees and are tied to two ponytails and is always seen wearing a white dress with long sleeves (just what does people from Greece wear.) she does by the way have her mothers eyes and her fathers tattoo on the forehead but instead of the Jr. sign it's a picture of a crescent moon and a small star in the center.

The kids who don't really know her looked her and she introduce herself,

"I'm Sakara, and I'll be taking care of you guys ." she smiled.

"As you can see she will be taking you all seventeen years back where some of your parents might been married at that time." said Koenma he looked at daughter once more and he was a nervous about her safety and what her powers will done to her.

"Seventeen years back." Hiro repeated. He looked at his sister and she looked back.

"Is there something wrong Hiro?" asked Koenma.

"Yes,"

"Our parents were only friends seventeen years ago and we don't want to risk us not being born." said Sayuri. Her mother told her that she was only friends with their father on that time and she didn't have time to explain about it.

Koenma shut his eyes and said,

"Well, you I have to leave you on that one."

Jello! I'm very sorry for the misunderstanding I reread this chapter and oh my lord i made a very big booboo on when the kids were going time traveling and i'd check in there time there parents are so old to have young kids so my bad!
