A/N: Okay, I'm bored. In the car, on the way to Ham. I'd be really happy, except I'm about to hurt some of the people in this car. They're playing the ABC game and looking at clouds, trying to figure out what they look like. .

~*~ Gryffindor Common Room ~*~

Kurama sat in one of the chairs, working on extra credit for Herbology; which was quite easy for him. Yusuke slept in a chair next to him, about to fall out. Hermione, Harry and Ron sat in their favorite chairs by the fire, doing homework. At least Harry and Ron were, Hermione was pretending to. She kept checking her watch, then looking to Kurama and Yusuke.

"They look so. calm. Don't you think they should be worried because we're still here?" she whispered to Harry and Ron. Ron stopped writing for a second.

"Hermione, calm down. We'll pretend to go upstairs in a little bit, okay? Unless you want to go and investigate them about it." He said, before turning back to his homework. "Where was I."

Ten minutes later, Harry, Ron and Hermione closed up their books and walked upstairs. Harry got out his Invisibility Cloak while Ron got out an Extendable Ear and let it down to listen to Kurama and Yusuke. Hermione in her own dorm room was also getting an Extendable Ear ready. But instead of going downstairs, the end of her's was in the boy's dorm. When everything was set, they sat and waited.

Downstairs, Kurama began to put away his school books. He left them on the table where he had been sitting; planning to get them when he came back. He stood and stepped over to Yusuke. "Yusuke, time to get up.. come on Yusuke." He soothed. Yusuke slowly opened his eyes.

"What is it Kurama? Morning already?" he said after he yawned. Standing up her stretched while Kurama spoke.

"No, its not morning. Hiei and I are going out to train with Genkai-sensei; and I was wondering if you would like to come and watch." Kurama replied smoothly, flipping his hair back out of his face.

"I thought I heard you say something about training when you went to ask Grandma about 'homework.' Sure I'll come." Yusuke walked over to the back of the portrait. Kurama followed him out and the two began their decent to the Forbidden Forest.

"Come on Hermione, we're going downstairs." Harry said towards the Extendable Ear lying motionless on the floor. It soon disappeared and Harry and Ron walked down to the common room. Here they met up with Hermione. Throwing the Invisibility Cloak over himself and the others, Harry led the way out into the hall.

Once they got outside, they were just able to see Kurama, Yusuke and Hiei at the edge of the Forbidden Forest. But also there was Kuwabara and Botan. Botan could be seen and heard yelling at them as Harry, Ron and Hermione got closer.

"You two can't battle! What happens if you get hurt and then Voldermort attacks Harry?" Ron and Hermione made a little gasping sound, but it wasn't heard by the others.

"Calm down Botan, these guys know what they're doing! Their skilled demons, they aren't going to hurt each other." Yusuke said, his eyes drooping. Hermione gave Harry a little push, but Harry ignored her. He was too busy trying to listen to the conversation in front of him.

Just then, a small figure moved forward from inside the Forbidden Forest. Harry almost leapt out and attacked it, but he restrained himself. A husky voice came from the shadowed figure.

"Would you two stop bickering and follow me? Last thing we need is to have seomone wake up and find us out." Even though Ron, Hermione and Harry had only heard this voice once before, they all knew who it was. At the same moment, the same thought crossed each of their minds. 'Professor Genkai.'

"Oi, baba! How come you gave us so much homework in class?" Yusuke asked, his head turning to face Genkai.

"Because I want to look like a real teacher, that's why. None of you have to do any of my work if you don't' want to. All of you are getting full marks on every test." Genkai responded. Kuwabara and Yusuke let out a "whoop." Aside from Botan's smile, the others didn't seem to register this idea or didn't care. "Well, let's get going. We only have a couple of hours." Genkai turned and walked farther into the Forbidden Forest. The group of new students followed her. Harry, Ron and Hermione slowly began walking forward. They soon had to hurry, though, because once in the Forbidden Forest, the black surrounding darkened even more.

"Where is she taking them?" Ron asked quietly. Harry made a slight shrug. Then he looked in front of him and noticed Hiei had disappeared.

"Hiei," was the only word Harry said, but Ron and Hermione both knew what he ment. A couple of minutes later, they arrived in a clearing. Out of a tree, Hiei came into the center of the field. Harry, Ron and Hermione stayed on the side of the meadow. They were still able to hear Genkai when she said,

"Hiei, Kurama, face each other. The rest of you stand behind me." Everyone moved according to what Genkai had said. Once everyone was still, she continued. "The two of you will fight normally. No Yoko, and no Dragon of the Darkness Flame. Understand?" she asked, directing her speech towards Kurama and Hiei. Both nodded. "All right then. Begin."

Kurama instantly pulled his hand through his hair, pulling out a rose. He gave his wrist a slight flick, and the rose turned into a whip; covered in thorns. Hermione gasped, noticing all the rose petals everywhere. She told the other two that they had to move, or the petals would fall onto them. Kurama let his whip fall to the ground in a tight circle as the three watchers moved.

Next, Hiei reached back and pulled out his sword. For a second, he disappeared then landed right where he had been. But when he landed, his sword was out in front of him as if he had sliced through something. He was also on one knee as if bowing. A few seconds later, two giant trees fell. By the way they had been cut, Hermione guessed Hiei had somehow cut the two trees.

Kurama smiled at Hiei as he stood up. "Ready Hiei?" he asked in a low voice. Hiei made no movement that Ron could see, but Kurama soon spoke again. "Good, because I need an aware opponent." Kurama ran forward towards Hiei, and lashed his whip out at him. Hiei quickly dodged and made his own attack. Seconds later, the pair had disappeared.

"Where'd they go now?" Ron asked in a rather loud voice. At the same time, both Harry and Hermione said "SHHH!" All three looked over towards Yusuke and company to see if they had notice. Genkai was looking towards them out of the corner of her eye.

"Ron, be quiet. I don't know where they are. But in History of Magic, if you had been listening, you would have heard Professor Binns telling us able these creatures, demons I think, that were able to travel faster than the human eyes could see." Hermione whispered quickly; her eyes traveling back and forth trying to see something in the clearing. Suddenly they heard Genkai shout out.

"Stop now!" was all she said. Kurama and Hiei came back into sight. Both had small marks all over their bodies where weapon had meet skin. Kurama was only bleeding on his shoulder, but it was a small straight cut. Here had a mark on his cheek and a slight amount of blood was dripping down.

"Both of you, during Kurama's last attack, were horrible. Kurama, when you raised your whip you left your stomach wide open. And Hiei, why did you not attack when you could? You dodge to quickly as well, Kurama had plenty of time to change his attack." Genkai grunted and stepped forward. "We're going to try that again. And Yusuke, you are here to practice your sight. Stop staring at the trees over there and make sure you see every attack." Yusuke nodded, his eyes turned and locked on the pair of fighters in front of him. This time, Hiei came running towards Kurama. Soon the pair had once again disappeared from Harry, Ron and Hermione's view.

It was then that they realized that Yusuke and Botan had also been looking in their direction. "Come on, let's go back now. I don't want to be seen." Hermione said, turning slightly. Harry nodded and turned as well. But Ron's eyes were focusing on the spot where Hiei had just stood before.

"Come on Ron." Hermione hissed, pulling on his shoulder.

"Oh, right." he said, also turning. The three walked silently back to the castle, and up to the Gryffindor common room. Once in the common room, Harry pulled the Invisibility Cloak off the three of them. Hermione began to walk towards the stairs.

Stopping by the chair Kurama had been sitting in she said, "Hey what's this." Harry and Ron both walked over to her. Hermione picked up Kurama's schoolwork, and turned to face the others. "It's Kurama's school stuff. I wonder why he left it out."

Harry shrugged. "He probably is going to get it when he comes back. Just leave it were it was, we don't want him knowing we were up." Hermione nodded and turned to place the books back down where she had found them. That's when a little piece of paper fell down onto the ground.

Ron's eyes fluttered to the piece of paper as he reached down to grab it. He stood up again with it in hand, and began to open the folded parchment. Then he read the letter aloud to Harry and Hermione. "Hey guys listen to this: Dear Kurama, Yusuke, Hiei, Botan and Kuwabara. I know what you're up to; I can see your pathetic plans. Keep away from Harry Potter, the boy is mine. Do not think you can defeat me, for I am much stronger than all of you are. I suggest you leave Hogwarts now. Its signed Voldermort!"

Harry and Hermione were speechless. All three just stood there for a moment, thinking. "What does he mean, 'Keep away from Harry Potter?" Harry asked quietly. "Are they trying to kill me like Voldermort is?" Hermione was quick to respond.

"No. If they were trying to kill you, they would have done so long ago. Besides, he said something about defeating him. Maybe they're on our side." She sighed and sat down in the chair behind her. Ron and Harry stood staring at each other.

Right then, all three heard someone or something behind them. They turned to see Kurama, Hiei, Yusuke, Botan and Kuwabara walking into the Gryffindor Common Room, deep in conversation. They too stopped when Hiei said,

"Looks like we aren't alone."
