Author's Note: I know that this story may sound like my story, 'The New Yusuke Urameshi', but I'd like to make some adjustments to the story. Instead, I'll put this story in the Yu Yu Hakusho section. I own Hikari Urameshi.

Chapter 1: Back from Demon World and Surprises

It was the day after the Demon Tournament, in Raizen's castle Yusuke Urameshi was packing his things to go back home. He spent three years in Demon World and he was feeling a bit homesick. He missed every one of his friends at home, his mom, his sister, Keiko, hell even Kuwabara's ugly mug as Yusuke would say. After he finished, Yusuke walked out the castle after saying goodbye to his followers.

'Probably, I should pay the old man a visit,' he thought as he walked towards Raizen's grave, "Hey, just to let you know that the tournament is finished and sorry that I didn't make it," he said

Just then a transparent image of Raizen appeared on Raizen's gravestone, "Don't mention it," he said, "At least there won't be any human killing or eating anymore."

"Yeah, I guess that some good came to it," Yusuke said, with a lopsided grin

"So, you're going back?" Raizen asked

"Yeah, right away of course," Yusuke said, "There's a certain brown haired girl that I missed so much."

Raizen let's out a chuckle, "I see that this girl has a violent temper that she unleashes on you."

Yusuke smiled, "You have no idea," he said, "I guess that what I missed about her. I'll see ya, around, Dad."

"See you around, Yusuke," Raizen said as he disappeared

Yusuke walked away from the grave and from the cemetery. Yusuke stopped and put his hands in front of him, "I guess that this is it," he said, as energy came out of his hands and created a black portal. The black haired teen jumped into the portal.

In the human realm, the portal opened and Yusuke jumped out and landed on the grass, "Ah! Feels great to be back!" he exclaimed with happiness

"That was sure quick, dimwit!" came a so familiar voice

Yusuke looked behind him to see Genkai, with her arms behind her with a smile, "Hey Grandma," he greeted and noticed something weird, "You sure haven't aged a bit."

Genkai raised an eyebrow, "What are you talking about?"

"Well you look like the way I remembered you, three years ago," Yusuke said

Genkai shook her head, "Same old, Yusuke."

"What's going on here, Genkai?" Yusuke asked

"Follow me, dimwit," Genkai said as she walked ahead with Yusuke following to the pond, "Take a look at this"

"Okay" Yusuke walked towards the pond and looked at his own reflection, which appeared to look like a fifteen year old version of him, which he was freaked out, "Whoa! Whoa! I just look like I'm still fifteen years old!" he exclaimed

"That's because you are fifteen years old, Yusuke!" Genkai told him

"But I was gone for three years"

"No, you wouldn't," Genkai said, "You were gone for three weeks."

"WHAT!" Yusuke exclaimed, with disbelief, "How could it be three weeks!"

"Maybe, Demon World time is different from this world," Genkai said, "So, in other words a year in Demon World is like a week in this one. When, you crossed from that world and this one you were made three years younger than you were at Demon World."

Yusuke was stumbling and trying to keep balance, "So that would mean that, I'm still in junior high and nothing has changed." Yusuke said

"So, what would you do now?" Genkai asked

"Right, since I'm an S class demon now, I'm practically stronger than anyone here." Yusuke said and shrugged, "Oh well, I guess that idea would pop up sooner or later. Goodbye Genkai, nice seeing ya again!" Yusuke walked off to the entrance of the temple and walked towards the stairs, "I wonder if I can make it down these stairs in four leaps," he said to himself, "It's worth a try" He jumped up and got down the stairs in four leaps without tripping, "Okay that was boring to even try and I'm still bored." Yusuke sighed, "Well, back to the old drawing board."

Yusuke was walking in the streets of Japan, 'It sure is good to come back home, I could visit Kuwabara or Keiko but they're at school now or I could get home and mom's gonna kill me because I didn't get that 6-pack.' He thought. A few moments later, he arrived at his apartment and opened the door, only to smell nothing…, "HOLY SHIT!" he screamed as he dropped his stuff and rushed to the kitchen to see that the oven is burning, "WHOA!" he screamed as he went to get the fire extinguisher and blew the flames away. Yusuke breathed heavily and came to a conclusion, 'Hey wait a sec,' he thought, 'Mom doesn't cook, I wasn't here and definitely can't cook and Keiko can cook and has enough sense to not to leave the oven on unattended, so the only that has the house key, could pull something this stupid and tries to cook and made us sick from it is………' Just then a sound of the door opening occurred, "She comes to the scene of the crime," he said to himself as he walked out of the kitchen, "Hikari!" he screamed, "You left the oven on again!"

"Oh shut up!" Hikari snapped, "At least I try to cook, Yusuke!" she set the groceries on the table.

"Yeah, tried to kill people with it," he muttered under his breath, "What was that, baby brother?" Hikari snapped and glaring her dark piercing brown eyes at Yusuke, which was very similar to Keiko's glare and as always, would scare him.

"Nothing, big sis!" he squeaked, with fear

Hikari Urameshi or Kari, what her brother, Yusuke and friends call her is Yusuke's twin older sister by two minutes and made sure that Yusuke never forgets it. She looked kind of like Yusuke, except in girl form, has brown hair instead of black and an athletic body, and isn't a street punk, plus much smarter and mature than her brother, except she fights only bullies and not rebellious like her brother and has a very dirty mouth like Yusuke. Her punches and temper towards Yusuke rivals Keiko's, which could be a very useful tactic towards her brother. Her long dark brown hair tied to a ponytail and wore a white dress shirt, jeans, white sneakers and a denim jacket.

"Where's mom?" Yusuke asked

"She's at a friend's house for the weekend," Kari said, "Probably drinking again."

"How was the visit to Duel Academy?" Yusuke asked

"It went well, we're just getting ready till then," Kari replied, as she put the salt in the cabinets, "You should apply though."

Yusuke was going to object to that request, until he really needed something to do with his spare time.

Kari had finished putting the groceries away and looked at Yusuke, who was walking towards like with a smile on his face, which scared her a bit, "Yusuke, what are you doing?" she asked as she felt her brother's arms wrapped around her waist and pulled to a hug, "You just given me an idea, Kari."

"You do realize I was joking, right?" Kari asked

"Yeah, but I'm serious"

Kari raised an eyebrow at this and smiled and wrapped her arms around Yusuke's shoulders, returning the hug, "You do realize that it's gonna be hard to get into," she said, "It's the best dueling school in the world."

"I know, but I want to at least try."

Kari pushed Yusuke away and made him look her in the eye, "You can't keep skipping the classes there like you've been doing in school, you know." She told Yusuke

"I know okay," Yusuke said, "When are you going?"

"In four months"

"When is the written exam?"

"In three weeks, Yusuke, do you even know how you are in duel monsters?"

Yusuke knew how he played duel monsters, he played very horrible and has beaten Kuwabara every match they'll get with each other, "I know," he said, "You could tutor me, right?"

Kari was shocked at this, because Yusuke has never asked her for any kind of help before from her, which meant that he was being drop dead serious, "Listen, tomorrow I'm going to Domino to see Grandpa and Yugi, I guess that you could come with me."

Yusuke smiled, "Thanks Kari,"

"Hey, what are big sisters for?" Kari asked, with a wink at her brother

"I'm going to my room, now," Yusuke said, as he walked towards his bag and picked it up

"So, how was Demon World?" Kari asked

"Well it's the…." Yusuke came the conclusion that Kari has never been told about the spirit case with Sensui that Yusuke was involved in, "Okay, how did you know?"

"Botan spilled the beans"

"I'm guessing that you know that your brother is now an S class demon called the Ma-zoku," Yusuke said

"You too!" Kari said, to Yusuke's surprise, "Hey wait a sec, you're a Ma-zoku also!" Yusuke asked

Suddenly, familiar marks appeared on Kari's face, "Well, yeah, like you."

"How did this happened?" Yusuke asked

"There was this powerful demon that killed me, when I was at Dueling Preschool and I was resurrected as a Ma-zoku. Botan told me that you were killed for the second time." Kari replied, showing off her fangs, "And this form was at least a month ago and I tried to hide the marks with make up."

'A month ago, that's when Sensui died,' Yusuke thought, "Hold on, you're not gonna eat any humans, are you?"

Kari giggled, "No, of course not!" the marks disappeared from Kari's face, "So, did you see Raizen?" FYI: Hikari was with Yusuke during his days as a spirit detective until the start of the Sensui case.

"Yeah, I did," Yusuke said, "He's also our ancestral dad."

"I bet is better than the bastard, who left us when we were in diapers," Kari said, with venom in her voice, "So, any idea on how you're gonna explain this to Keiko and Kuwabara? They expected to see you in three years not three weeks."

"Yeah, I know," Yusuke said, "But, this should be a surprise to them that Demon World years is weeks in this world." Just then the sound of the door begun to unlock to reveal Keiko Yukimura and Kazuma Kuwabara standing behind it, "Hey Kari, we're here!" Kuwabara declared and when he and Keiko looked at Yusuke, they were shocked, "Hey guys, what's up?" Yusuke greeted, innocently

"Hey Kuwabara, today's lunch at school was unusual, right?" Keiko asked, with disbelief, "Because I'm seeing Yusuke here in front of us."

"Yeah!" the two teens walked towards Yusuke and poke him to see if it's an illusion or not. They kept poking him until Yusuke got to a point that he was very vexed, "WOULD YOU TWO KNOCK OFF, I'M NOT AN ILLUSION!" he yelled and slapped the fingers away

Kuwabara was stammering, while Keiko was in a loss of words, "N-no way!" Kuwabara said, "He's definitely real!" Keiko added

Yusuke scoffed, "Some friends!" he said, "I'd expected to have a warm welcome from you, instead I get to be poked."

"Urameshi, you were…..I thought that you were to stay in Demon World for three years, not three weeks!" Kuwabara yelled

"Right about that it, appears that I have some explaining to……" Yusuke was interrupted when a sound of something dropped on the ground, "KEIKO!" Yusuke and Kari yelled, as the see the brunette on the ground, unconscious, knowing that she faulted.
