Keiko's Ghost:
Yusuke Urameshi hovered above the buildings as he gazed down at the girl hurrying down the street.
"Yusuke" Botan greeted happily, appearing at his side "how are you today?"
Yusuke waved a hand sharply, silencing her "ssh"
"Are we spying on Keiko again?" Botan demanded.
Yusuke frowned, but didn't reply. Instead, he watched as Keiko's pace slowed. Then, like the previous times, a group of unknown students encircled her.
"Hey Yukimura" one of the boys greeted with a leer "you're Urameshi's girl, aren't you? That isn't counting for much since he's dead."
Keiko avoided his gaze, staring at the ground. She wished that she could tell them that they were wrong. That Yusuke wasn't dead... that he was still alive.
"Look at me, bitch!" the boy yelled, and slapped her.
Keiko gasped, reaching up to lightly touched her reddened cheek.
Yusuke growled, slamming his fists together.
"Botan, tell me how I beat them up" he muttered darkly.
"Um, you can't touch them" Botan admitted nervously, shooting a look at the furious ghost.
"Why not?" Yusuke demanded "he hurt Keiko! There's got to be a way that I can beat them up!"
"Well..." Botan shot a look at Yusuke "there might..."
---------------------------------------------
The three boys entered the room.
"That was so funny!" the one who hit Keiko laughed.
"Yeah... Yukimura is pretty cute though."
"Are you kidding? She's Urameshi's girl... what the hell happened to room?"
The room was in shambles; the furniture destroyed and paint poured over the mess.
The three stared in horror at the message on the wall. It said:
"Stay away from Keiko. Stop bothering my girl!"
"Urameshi's ghost!" one of them yelled "ah!"
All three turned and ran.
They avoided Keiko after that.
---------------------------------------------
Yusuke smirked as he watched Keiko walk down the street, not bothered by anyone.
"They won't be bothering her anymore" he said proudly.
"Remember Yusuke, you owe Koenma a favor for that" Botan said "ghosts aren't really supposed to be allowed to be poltregists."
"How else was I supposed to teach them a lesson?" Yusuke demanded "I had to do something Botan."
"Yes Yusuke" Botan sighed heavily "and what will you do next time?"
"Next time?" Yusuke demanded "what do you mean by 'next time'?"
"I'm sure that other people will decide to harass Keiko" Botan said calmly.
"They better not" Yusuke muttered darkly. His face darkened "I'd better do something about them too."
Botan laughed "Yusuke, you can't scare them all" she said.
"I will" Yusuke said stubbornly, crossing his arms across his chest.
"Let's go talk to Koemna then" Botan suggested "come on, let's go!"
---------------------------------------------
Keiko was never bothered again. The few people who decided to stopped quickly when mysterious frightening things happened to them. Keiko never found out about it; instead she forgot quite quickly about it.
Yusuke meanwhile, was quite satisfied watching his extremely rewarding work.
He was quite happy scaring away all of Keiko's tormentors.
He decided to ignore all of Koenma's teasings about his hobby of guarding Keiko.
He kept watching after Keiko though... but didn't like the name he was given... Keiko's Ghost.
