Summary: What if Yusuke had a younger sister? Would everything happen differently? See what went on in my crazy mind if Kyokai Urameshi was thrown into the plot!

Disclaimer: I own everyone in Yu Yu Hakusho. Yep, I made all those crazy things happen. You believe me? Dude, I have no money to claim Yu Yu Hakusho. I only own Kyokai.

Quick little explanation: Kyokai was the name Yusuke's father gave her (you will find out the meaning of it) but since she knew by instinct what her name meant, she didn't want it to slip so when she was enrolled at school, she put her name as Lyoko. Sorry, so when I say "Kyokai" or "Kyo" and someone calls her "Lyoko" or "Lyo" I mean Kyo, kay?

OOOO

Chapter 1

Kyo waited patiently for Yusuke to come down to meet her so they could walk to school. Her phone buzzed.

"What?" she asked gruffly.

"Hey, sis, listen, uh… I ain't goin' to school today, 'kay? Bye!" Click.

Kyo snapped her phone shut and gripped it tightly, baring her teeth. Yusuke, you punk, she thought. She stomped up to her apartment and grabbed Yusuke by the ear and dragged him to school, Yusuke crying out, "Ow!" the entire way.

Kyo plunked Yusuke down in his seat and glared threateningly at him.

"Stay. Put," she growled. Yusuke shivered.

At the end of the day, Yusuke yawned, happy school was over. He waited patiently while his sister packed up her things. An announcement came on over the speakers.

"Lyoko Urameshi to the office, please."

Kyo smiled at Yusuke. "Go on home. I'll check it out." With that, she walked out of the classroom.

Yusuke stood outside the office waiting for Kyo.

She finally came out a few minutes later.

"Well?" Yusuke asked.

"Just thanking me for dragging you to school," Kyo smiled.

Once Yusuke and Kyo made it off the school grounds, they were hit by a rush of wind.

Kyo clung to her brother's arm tightly. Yusuke wrapped a protective arm around his sister. Yes, he may seem to hate her, but he was the only female he was related to that wasn't drunk or stoned, or something like that (no offense to Atsuko. I respect her with all my heart).

"Hello, Detective. Lyoko."

Kyo looked up and her eyes brightened. "Hiei…" she murmured.

"'Sup, Hiei?" Yusuke smiled.

"Koenma just wanted me to give this to you," Hiei said, giving Yusuke an envelope.

Kyo looked at the envelope with awe and wonder.

"Should we read it when we get home, Kyo?" Yusuke asked. Kyo smiled and nodded.

"And Koenma told me he wanted your sister to be a part of the team," came a voice from behind. Kyo and Yusuke looked back to see Botan.

"What?" Kyo asked.

"Kyo," Botan started. "do you know what your name means?"

Kyo's face was then grim. "Yes," she replied nodding.

Hiei's eyes lit up. "What does it mean?"

Kyo looked at the ground. "It means Hateful Warring Demon," she whispered.

Yusuke's smiled had also vanished.

"Mom told me… Dad insisted on that name…" Yusuke said.

Botan's breath caught in her throat.

"I don't like my name," Kyo whispered. "Even the nickname 'Kyo' means 'Hateful War' for Christ's sake!" She let go of her brother's arm and ran off. "I'm sorry. I can't be on the team," she whispered to Botan when she passed the Shinigami.

"Kyo…" Yusuke murmured. "Yeah, she doesn't like 'Kyokai'… she prefers Lyo or Lyoko." He started walking after his sister. "I know where Kyo goes when she's like this."

Botan shrugged to Hiei and followed, Hiei coming along, too.

Botan and Hiei found Yusuke and Kyo up in a tree. Yusuke trying to coax his sister to come down.

"I-I don't want to," Kyo hiccupped. She had been crying. "I don't like Life…"

"Well, Dad was an idiot for your name choice. I mean, come on, I can start callin' ya 'Lyo' if ya want. Sis, you mean a lot to me. I can tell Mom to stop calling you 'Kyo' if you want," Yusuke said.

"Can you?" Kyo asked through sobs.

"Promise," Yusuke said.

Kyo smiled and Yusuke picked her up and jumped down from the tree, setting her down.

Maybe… I should be a better brother, Yusuke thought. (A/N: YA THINK?)

"Did you change your mind?" Botan asked.

Kyo nodded.

"And she goes by Lyo now," Yusuke said.

Botan nodded.

Yusuke grabbed his sister's hand. "Come on, let's get home."

Kyo nodded.

OOOO

"Hey, Lyo, you almost ready? I wanna show you somethin'!" Yusuke called.

Kyo came down that minute, tying her hair up. She gasped when she saw what Yusuke was wearing. She smiled and her eyes started tearing up. She flung herself at her brother.

Yusuke was wearing the proper uniform for school.

OOOO

Shippa-chan: okay, might've made Yusuke a little OOC, so sorry. :( This was all written at 9:36 PM... So…
