Again, I only own Kasumi, Kiyoshi, Takeshi, and Akiko. I do know it's pretty long, and a lot of description. But who my four characters are is a bit complicated. I figured it would just be easier to say it outright than to try and give enough clues about it to have you all figure it out on your own. Thanks.

Since I haven't been able to figure out a place to include a physical description of my four main characters in the actual story, here they are.

Kasumi: five foot four, dark hair that almost reaches her waist, medium brown eyes, 16

Kiyoshi: five foot seven, short black hair, dark green eyes, 15

Takeshi: five foot five, dark brown hair reaching a little past his chin, pale brown eyes, 14

Akiko: four foot nine, pale blonde hair, very light blue eyes, 19

And this chapter is dedicated to kurama1sauske1 for their quick review. :)

"A throwback." Koenma echoed Kasumi. Only seconds later her put all the pieces of the puzzle together, understanding the full implications of the statement the girl had made. Eight generations ago, one of Kasumi's grandmothers never married. Because she was in love with one of the missing members of the team. And eight generations ago was when this particular throwback line had been created. And that line knew the basic idea of releasing the demonic side. Another thing was her eagerness to join and how quickly she believed what he told her. And her lack of questions. That could only mean one thing. "The grandfather you mentioned, the demon, was he…?"

When he trailed off, she just looked at him stoically, and he understood that she was going to force him to say it aloud. "Was the demon a demon throwback like yourself? And did he go by the name of Yusuke?"

She clapped slowly and loudly, acknowledging that he was correct. "Congratulations. You figured it out. My grandmother Keiko never stopped loving him; he never stopped loving her, either. He'd come and visit her every few years. And her diary—a family heirloom, now—starts with the night he revealed everything to her. The night he went missing."

Koenma was in shock. How did she know so much? And how had this escaped not only him, but everyone else in the underworld? How had Keiko kept that secret from him the many times he had questioned her throughout her life? Just as he opened his mouth to ask, she answered his unspoken question. "We don't know where he went; where he was then or where he is now. He never told her. She understood. But he still felt guilty. One time he visited, he felt bad enough about leaving her alone, that he told her he and Kurama and Hiei were still traveling together. That's all the diary revealed. That and the fact that she lived for his visits, she loved him so much. The last thing in the diary is a note she wrote to her daughter just before she died. It said that the man, Yusuke, who visited every couple of years was her father. Her daughter met with Yusuke at the funeral. He continued his visits for the rest of his daughter's life, teaching her aura-building techniques and other weapons, that even humans could use, which were then passed down through the generations. Those and the story of his transformation. Finally reaching me." And from under the she pulled an index finger that was silently glowing. Koenma leaned forward slowly, and rested his forehead on the edge of the table. Not again, he thought.

Six days later he met with the entire group. They ignored each other so intently, it couldn't have been an accident, and they waited for him to speak. Botan stood nearby holding what looked like three makeup mirrors. Koenma said, "I believe you have all met Botan?" They nodded and she handed each of them one of the devices, except Kiyoshi, because he already had one.

"Press the button on the left to contact Koenma, the one on the right to contact me. Always try the right first, unless it's an emergency." She said. Then Koenma took over.

"Okay. Your first mission…"

"Wait." Kiyoshi said, sounding panicked. "What about the training?"

Koenma just smiled, "Your first assignment is to travel to this temple, where your training will then take place." He showed them a picture and handed a map to the nearest, which happened to be Takeshi.

"I bet I'll get there first," Takeshi muttered.

"Here's the catch: you must all work together." Audible groans issued from the teenagers in front of him, but he ignored them. "Botan and I will be there when you arrive, along with the master of the temple. Go." And with that, he and Botan disappeared.

As soon as they were gone, Kasumi spun around and before Takeshi knew what was happening he was knocked to the ground by the force of the collision of Kasumi's fist with his face.

He looked up at her from the ground, bewildered. "That was for the last time we were both at school and you told the principle I was smoking on the roof." She leaned down and whispered threateningly in his ear, "Next time you get me suspended, it'll end up getting you something more than a relatively painless punch in the mouth."

Kiyoshi's mouth dropped open. Akiko merely stood to the side, looking bored. Kasumi stood back up and said, "Okay, let's get this show on the road. Literally." She grabbed the map off the ground from where Takeshi had dropped it. She saw the place Koenma had circled in red ink, and started off.

Jumping up, Takeshi said, "Where are you going? We're supposed to work together."

She stopped and turned around. Looking calmly at Takeshi she said in a voice so quiet it was threatening, "Oh, but Takeshi. I thought we were working together." Her eyes flashed violently and her hand curled silently into a fist.

Takeshi glanced at it, glared, and then followed Kasumi when she turned around. Kiyoshi had already decided it was best just to do what Kasumi wanted unless it was downright dangerous or stupid. Akiko just chuckled, muttering to herself, "I like this girl already." She then followed the other three to wherever it was that Kasumi was leading them.

Little did they know, Koenma and Botan were watching them. They followed the small group to a bus stop, and onto the bus, each person paying there own fare.

Half an hour later, they got off. Kasumi and Akiko set off in the direction the needed to go, mindful of only one thing: reaching the temple as quickly as possible. Takeshi and Kiyoshi followed.

A shrill beeping suddenly burst forth from Kiyoshi's pocket. He pulled out the device Koenma had given him and flipped it open. Koenma stared back at him from the small screen. "How's it going, Kiyoshi?"

"Fine. Well, not really. Takeshi and Kasumi already hate each other."

"Why isn't this surprising?" Koenma muttered, more to himself than to the fifteen year old he was talking with. "I suppose blood runs even thicker than I thought. I thought that after a hundred and fifty years and eight generations this feud would have disappeared. Although, when I talked to him, he wasn't upset about dying as much as he was upset about never defeating Yusuke in a fair fight. I guess that desire was passed down unknowingly, until it finally reached Takeshi and Kasumi."

Kiyoshi just listened, understanding intuitively that this could be the first clue as to why Koenma had chosen the four of them over all the other spiritually gifted people in the world. Suddenly, the communicated flashed off, so he shut it and stuck it back in his pocket.

Dragging Takeshi by the sleeve of his jacket, Kiyoshi walked up to Kasumi and Akiko and said, "Do any of you three know something about a man named Yusuke? I think he was a member of the Reikai Tentai Koenma created about a hundred and fifty years ago."

Upon hearing Yusuke's name, Kasumi stopped dead in her tracks. "Yusuke was one of my ancestors. The other three members were Kuwabara, Kurama, and Hiei."

"If you're the one who's related to Yusuke, then Takeshi must be related to another member of the team. One who apparently died without fulfilling his long-lived wish of beating Yusuke in a fair fight."

Kasumi groaned. "Kuwabara." She spun and faced Takeshi. "Is there a Kazuma Kuwabara in your family?"

He nodded. And she smacked her hand to her forehead. "Wonderful. Descendants of the old team. Just spiffy. That's how he picked us. That makes me feel just wonderful. I'm not picked for my abilities, but for my lineage."

"Koenma did mention something about that when I met with him." Takeshi said.

"So who are you two?" Kasumi asked, suddenly addressing the other two members.

Akiko replied quietly, "Hiei was one of my grandmother's twin brother. He told her this—he had kept it hidden from her, thinking that to be what was best—just hours before he disappeared."

Kasumi looked at Kiyoshi. "That means you're from Kurama's line. Which means you must be a throwback like me."

"A throwback?"

After a moment's silence she said, "Then again… Kurama never fell in love. At least not with a human. But if not Kurama, then who?"

"The only thing I could connect this to would that be one of my grandmothers—seven or eight generations back, of course—had a son who went missing. That would have happened around the time Koenma's last team went missing. Could that have been Kurama?"

Everyone just stared at him. He obviously hadn't any idea who he was talking about, and yet the circumstances of Kurama and this missing son fit together perfectly. They were stunned simply by his logic. Finally, Akiko said, "Kurama inhabited a human body for sixteen years, after which he went missing. It's entirely possible that they are the same person. The person Kurama considered to be his mother was an entirely human woman by the name of Shiori Minamino. Does that name ring any bells? And if it does, did she have another son after he disappeared?"

"I think so." Kiyoshi muttered. But before he could ask another question, Takeshi interrupted.

"Whoa." After hiking up a mountain through fairly dense vegetation, they had found the temple. And it was bigger than they had thought it would be. In fact, it was absolutely massive. "This must be the place," Takeshi said weakly.

"Thanks for the obvious," Kasumi replied.

Botan and Koenma came out the doors, having somehow arrived before them. Behind them was a woman older than anyone they'd ever seen before. Anyone human, at least. Takeshi and Kasumi scoffed openly. "How can she teach us anything? She's so old she should barely be able to walk." Kasumi muttered. Takeshi snickered in response.

And, suddenly, they were knocked over by an unseen force. "That is what someone gets for questioning me." The old lady snapped, clasping her hands behind her back and glaring at them.

Kiyoshi looked startled, unaccustomed to displays of aura like that one, but Koenma merely laughed. "I don't advise messing with her. I knew that eventually hiring a new Reikai Tentai would become a necessity. It took a great amount of persuasion to convince her to hang around the human world until then, instead of dying and traveling through Reikai. And only her already-amazing spiritual power made keeping her alive even possible. And she has progressed since then."

The woman chuckled. "I should have died over a hundred years ago. Well, technically, I did die, but your ancestors won a tournament in which they were granted anything they could wish for. They chose to bring me back, which their opponent and Koenma here made possible."

They all just stared at her, and she said, "Lesson one: quit gaping. Control of one's emotions is vital in effectively controlling and manipulating reiki, also known as aura." She glanced at Koenma. "There's no point in hiding it from them. I'm sure they've all figured it out by now anyway."

"Takeshi," she said sharply, making him jump, "Eight generations ago, one of your grandmothers was Shizuru Kuwabara, sister of Kazuma Kuwabara, possessor of the only known Dimensional Sword in existence. I hope I can at least build you up to a simple aura sword."

"Akiko. Your grandmother four generations ago was the twin sister of Hiei, Forbidden One, possessor of the Jagan Eye and the Black Dragon. Unfortunately, as an Ice Maiden, you won't be able to master the flame techniques he did. However, it should be a good indication of the levels of power you could reach, as aura capacity and spiritual abilities are often passed down through families."

"Kiyoshi. Eight generations ago, a woman in your family had a son named Shuichi Minamino. However, this was actually a demon by the name of Kurama. Shortly before he disappeared, she had remarried. Shortly after, she had another son, the start of your line. From what Koenma tells me, since her, your family has possessed a slight sense, most likely due to her continued exposure to Kurama's demonic aura. Also, a rare but not unheard of thing occurred. Since Shiori, your family has had a strange connection to plant life. Kurama was skilled at manipulating and summoning plants. It is possible that a slight amount of that ability was inserted in among Shiori's human genetics, simply from the nearly seventeen years of exposure to it. It was then passed down. My hope is that we can build on that enough to make it useful, although both Koenma and I believe it to be impossible for you to reach anywhere near Kurama's skill level, because despite that small amount of genetics, you are still human, and he is a demon."

Here she stopped for a moment before turning to Kasumi. "Koenma mentioned to me that you knew the father of Keiko Yukimura's daughter. You knew that it was Yusuke, which we should have realized before now. You also knew of the Reikai Tentai. You already possess the Rei gun so there isn't much I feel it is necessary to teach you. However there are some more advanced aura-building techniques that no one other than me knows exactly how to work. Also, despite your prowess, you don't yet have enough power to be able to undertake the transformation should you die. I want to work you up to that level of power, just as a backup."

She met each of their eyes. "You now know who you are and what I want of you. I expect you to work hard, and do exactly as I say. If you don't, don't expect to progress. And two final things. First, I will be observing you all throughout this training regimen, and, in the end, it will be I who chooses from among you the new Underworld Detective. In other words, I will decide which of the four of you is most suited to become the leader of the Reikai Tentai. The last thing I must say to you is related to the Underworld Detective. I'm sure you all understand this already, but I want to say it aloud just to make sure there is no confusion. My last pupil…" she sighed, the breathed in deeply; it was still difficult for her to talk about him. "I miss him deeply. He was annoying beyond all measure, but when he really put his mind on studying, he progressed quickly, although he always did better in direct combat. My last pupil was also an Underworld Detective. Yusuke Urameshi, missing person, and demon throwback. That's whose shoes you are expected to fill. Good luck."

Again she met each of their eyes. "I don't believe I've introduced myself. I am Master Genkai."

The reason for the end is that I suck at developing characters. So it's just better if I use characters I don't own as much as possible. I only own five, so far (one doesn't come in until the seventh chapter; yes I have written that far already, and that's the only reason you're getting updates so fast. Now I'm stuck, so that probably won't last long.).
