A/N: Linda: That's the first summary that I did a good job on! Please R&R, I hope you like it! Lydia: hehe, this is just about the best beginning we've come up with so far in all our fanfics! Linda: really. We're mean to Kuwabaka. In addition, to the readers, Lydia- chan is my other personality. ^-^

Chapter One: About the Culprits. "Hello Carrot Top." Came a voice as a small black figure entered the den of Kurama's house. The black haired man was about half way across the room when,

"Oh hi Hie- WAIT A MINUTE! WHAT'D YOU CALL ME SHORTY!?!?" Kuwabara had been standing by one of the walls, staring at the pictures of Suichi and his mother. Hiei just kept walking across the room.

"I called you Carrot Top. And it really does look like you have a carrot sitting on top of that head of yours." Hiei stepped slightly to the left, avoiding the fist attack that was coming from behind him. Kuwabara missed, and fell flat on his face. "What are you trying to do?" Hiei asked in a calm voice, turning around to look at the pile of limbs on the floor.

"I'M TRYING TO PUNCH YOUR LIGHTS OUT, SHORTY!" Suddenly, Kuwabara stopped talking and just stared into outer space. Stupid baka. Can't even keep one thought for two minutes. Thought Hiei as he turned around and began to continue his walk across the room. "Fine you get away this time, Hiei, but only because Yukina said something about not hitting you."

Hiei had turned around so fast, that a gust of wind could be felt coming from him. Kuwabara, who had tried to sit up, fell back over on his back from the gust of wind. "WHAT DID YUKINA SAY ABOUT ME???" He yelled, eyes bulging and face cracked in an evil snarl. Kuwabara got up from his spot on the floor, dusting himself off.

"Something about how she hated seeing people getting beaten up, and that I shouldn't beat anyone up unless I really have to." Kuwabara had a puzzled look on his face. "Why do you care, hmm?" Hiei just relaxed, straightened his outfit and turned back around again. All of a sudden, Kuwabara got a half-angry, half-comical look on his face. "Don't tell me you like her! Because she's my girlfriend, got it Shorty?" Hiei just thought to himself He doesn't know about you being siblings. Just let him think he's right.

"Hn" was all the answer Kuwabara got, which left him screaming at the top of his lungs "YOU STAY AWAY FROM MY GIRLFRIEND! YOU HEAR ME??" while Hiei just left the room. He went over to the fridge and got out a soda. Plopping down on the couch in the living room, Hiei grabbed up the remote and switched on the TV.

"HEY KUWABAKA!" Hiei heard yelled out by someone who had just entered the den. A couple of other voices could be heard as well. Hiei just ignored them, deciding instead to take a sip on his soda. He switched stations to the news, not caring what he was watching. Soon, a reporter came on with what was said to be 'urgent news.' Hiei listened in.

"Today, seven children have suddenly fainted from unknown causes. Their condition is like none other, doctors say." A woman came onto the screen, whispered something in the new reporter's ear and then walked away. The man continued. "Make that ten children, people. Please, keep your children inside the house and do not let them dehydrate themselves. Thank you."

Hiei tried to think of where he had heard of something like that happening before. Then out of the back of his mind, thoughts came floating back to him. "The orb of Baast! Now that I have this, I don't need to try to cook children anymore! This little beauty does it all for me. Perfect souls, ripe for the eating." (A/N: That's not the real quote, I'm to lazy to look it up.)

Of course! Thought Hiei, the last time something like this happened, was when we stole the Orb of Baast, the Forlorn Hope and the Shadow Sword. But I thought Koenma took those back. How did someone new steal this thing all by himself or herself, without me knowing?

Right at that moment, Yusuke entered the room. "Hey Hiei! What are you doing here?" he said, walking over and sitting down on the other end of couch. Yusuke looked to the television, seeing the news coming back from a commercial. Hiei was watching. TV? And the news, at that!

"Same reason you're here. Kurama called me, telling me Koenma wanted to talk to us." Hiei took another sip of his soda, switching off the television before anyone else could see what he had been watching. Lucky for him, Kuwabara, Botan, Kurama and Keiko entered right at that moment.

"I see you found your way to the couch, Hiei and Yusuke?" said Kurama, sitting down in between the two. Yusuke nodded, and Hiei only replied with a 'Hn.' Kuwabara sat in a chair, while Keiko and Botan sat in the love seat. All the group did was look at each other. None knew why they were there.

"You all made it, good." Said a voice from the doorway. Everyone looked up to see the teenager Koenma standing in front of them all. He strode over to a place in front of the television, and looked to each person in the room, one by one. However, before he could look at them all, Kuwabara shouted out,

"So why are we here? I've got things to do, you know!" he said, standing up front the chair. A small 'oh!' came from Botan, but besides that the room was silent. But that was only until a large POP sound came from where Koenma had been standing, and all eyes fell back to the now toddler Koenma.

"Oh calm down, you big oaf! I'll tell you why you're here, just wait one little minute!" He said, falling down into a sitting position on the floor. "I have a mission for you four. Keiko and Botan, you're here just to know what's going on. Someone, somehow, has gotten into my father's Private Vault again. Luckily, he's away on business so he hasn't learnt this bit of information yet. However, he comes back in two weeks! So I need you four to go and stop the Yokai from using the items from the Vault."

"Seems simple enough," said Yusuke, relaxing quite a bit. "I alone could get the three items from Hiei, Kurama and Goki. I don't see why you need all four of us to get them this time." Putting his hand behind his head, he began to laugh.

"Yusuke! Koenma-sama must have very important reasons for sending all four of you! Don't disrespect him!" Botan said, standing up. Yusuke stopped laughing, but still acted as though he thought this was going to be an easy task.

"Yes, I do have good reasons. The two Yokai who took the items are very strange. We didn't even know about them in the spirit world until the Vault was raided. Their names are Amaya and Mitsuko. Do you remember Juri from the Dark Tournament?"

"She was one of the refs. right?" Said Keiko, a puzzled look on her face.

"Yes, she was. Amaya looks just like her, with different hair and eyes. We don't have a description on the other girl. In the Vault, we found this note." Koenma popped something out of his hat, and handed it to Kurama, who then read it allowed.

"'Hello Koenma! We didn't think it was going to be this easy to get into the Vault after what happened with Kurama, Hiei, and Goki. If you would like your items back, send Yusuke and the gang over to find us! Have a good time while your father is away, Amaya and Mitsuko.' Well, at least they were kind enough to leave a note." Kurama handed the note back to Koenma, who in turn put it back in his hat.

"You see, these two girls want you four to find them. I can't tell if this is a trap or not, but you should go. The only reason I'm worried is that no one knew that my father was away! Except for me of course. And that little incident with you two and Goki," Koenma looked at Hiei and Kurama, "Wasn't just told to everyone! The only people that know about it are my father and us. I don't know where they got this information, but you must get the items back as soon as you can!"

"Right, we'll get straight on the case!" said Yusuke, who suddenly seemed to realize the importance of this mission. "Hey Keiko, sorry but as you see, I won't be able to go to school for a while. Do you think you could collect my homework?"

"COLLECTING HOMEWORK?!? Is that all I'm good for now?!? Yusuke!" Yusuke sank lower into his seat as Keiko yelled at him. Once she was done, she flipped her hair and said in a calm voice. "Of course. Sorry, I didn't mean to yell." Everyone except for her got a big anime sweat drop. (A/N: sounds weird in the story, but I had to say it)

Everyone stood up, and the four boys came together in the center of the room. Botan and Keiko left with Koenma. "So, we'll start our search tonight, alright then?" Said Yusuke who seemed pleased to be able to skip school again, but for a reason this time.

"Meet here, at my place around nine tonight?" asked Kurama. Yusuke and Kuwabara nodded, and Hiei didn't do anything. Kurama nodded in agreement and the others left.
