Kagome - 20

Ranma - 18

Yusuke - 15

In the recent years of his life, Ranma had been the victim to a lot of magic in its many forms. Liquid, spices, powder, pills, talismans, amulets and many more, even a wishing sword. But the sword that lay before him set off every danger sense he possessed, the sheer power sent chills up his spine and the pulses thundered through his body. He didn't like the feel of the sword, it was overflowing with yoki, and its pulsing had sent vibrations to his very core, his very soul. His pigtail stood straight up at the sensation, a reaction that was usually brought on by glomping fiancees, an angry Akane, and those of a feline genus, in other words, cats.

"Sh-Shippo . . ." He stuttered, for once at a loss for words.

"This is Tetsusiaga, the brother of Tensaiga, both forged of the same fang of Inutaisho, Inuyasha's father. It's purpose is to suppress a hanyou's demon blood so it doesn't rage out of control." Shippo sighed. "If Toutosai were still alive, he could forge a sword or some other item for Rei-chan of Mama's fang. As it is . . . we'll have to cross that bridge when we come to it."

Ranma's eyes were wide, he'd only heard of the Tetsusaiga from Kagome. And now, that very same sword lay in front of him, finally he understood why Shippo needed his help, Shippo couldn't touch it. Even though Ranma wasn't a weapons user, and rarely touched them unless he absolutely had to, he couldn't help but feel respect and a sense of reverence for the deceptively decrepit blade as he drew it from it's sheath and looked at it.

From the blade itself he felt a thrum that he could only describe as a feeling of excitement.

Shippo looked at Ranma's awed face and finally felt a slight smirk grace his features.

"Tetsusaiga's excited, it's not just your imagination. This is the first time in 500 years it's been needed." The smirk turned into a full out grin as Ranma turned his surprised face toward him. "Don't look so surprised, all magical items have sentience, that sentience is just determined by the level of their magic. But don't go telling anyone that. Now, hurry to the shrine and give it to Mama, she'll understand. It'll hurt, but she will understand that she needs it. I'm going to pick up your mother before meeting you there. Hurry now! And may the gods be with you! By the way, do you want me to pick up your father as well?" Shippo called as Ranma bounded up the stairs.

"HELL NO! The old fart can take care of hisself!"

There was a sigh of relief. He didn't need to move all his valuables after all.

Koenma Jr. sat at his desk shaking his head at one of the older files which had occurred several centuries ago, the actions of this yokai had landed him the position among the very select few who guarded the entrance to the Gate of Rebirth in the Reikai. A very surly fellow who desired nothing more than entrance into the Ningenkai once more. However, that wasn't possible, that realm wasn't ready for him yet.

"Hmmmm . . ." Koenma Jr. hummed as he skimmed over the profile of the yokai's mate, the least he could do for the yokai that guarded so well was deliver a brief glimpse of what happened to her.

The doors to Koenma's office were suddenly slammed open by his blue oni office assistant who was carrying a slim folder.

"K-Koenma-sama! There's been a level 2 transformation in the Ningenkai by this human!"

"WHAT?!" He yelled in shock. And indeed he was surprised to hear such a thing, there hadn't been a level two transformation in the Ningenkai since before the creation of the Makai. Snatching the folder from the oni he opened it and looked at the picture of the human girl that had been in it.

"Get me the file on this girl at once!"

The oni cowered.

"I tried Koenma-sama! But I don't have the clearance to access this girl's file, only Yama-sama and Kami-sama do!"

He instantly became still, frozen in the motion of putting the empty folder on his desk and eyes wide with disbelief. For the clearance to the girl's file to be so high . . . her destiny must be a large one, one that would affect the three worlds; either that, or she held an item of such power it could either deify her or transform herself into something else entirely, which was apparently the case. Letting these thoughts sink in, Koenma Jr. slowly leaned back in his chair with his arms folded in front of his chest and closed his eyes in thought.

She was a loose cannon, untouchable by anyone short of Kami-sama and his father. But he wanted to know why she was so off-limits, why she was an untouchable. The girl was a mystery, one he wanted to solve. Thoughtfully he chewed on his pacifier, surely there must be a way . . .

His eyes lit up as a brainstorm hit, her file might be off limits and no one from the Reikai or the Makai could touch her, but that didn't mean no one could keep an eye on her. After all, what were Spirit Detectives for?

"Summon Botan, I have a new case for the Reikai Tantei."

Gliding along the river Styx on her oar was so natural it only took a fraction of her attention, the rest of it was focused on the photo of a young woman that Koenma had given her as the assignment. She was pretty, Botan supposed, it puzzled her though; how could a mortal such as this suddenly be put through a level 2 transformation? Oh well, level 2 was better than a level 1, if that had been the case they would have had to kill her.

Eyes focusing ahead to the portal leading to the Ningenkai she quickly tucked the photo in her kimono and plunged into it. The energy which constructed the vortex swirled around her in colours of dark violet and black with a thread of light blue that wove itself between the two. Exiting the doorway between the two worlds she paused and glanced back, the blue wasn't normal; but it didn't seem to be affecting it in anyway . . .

She shrugged, Koenma-sama would take care of it if it was a threat.

"So, what does the toddler want now?" Yusuke mumbled as he stuck his pinky in his ear and twisted it around. Kuwabara hit him upside the head for his lack of manners in Botan's presence. Yusuke scowled at him.

"Three hours ago there was a level 2 transformation . . ." Hiei, who had been leaning against the wall with arms crossed over his chest and his eyes closed in disinterest suddenly opened them; Botan had his full attention now. Kurama's eyes widened a little as the surprise of the news made him loose his cool composure ever so slightly. The two humans of the team just looked at her blankly, not understanding the significance of Botan's message.

". . . here in the Ningenkai, and Koenma-sama wants you four to keep an eye on her, once you find her that is."

"Oi! Wanna cripple that and run it by us one more time? What's this level 2 thing? And why do we hafta find this chick in the first place? Doesn't the toddler know where she is?"

Kurama glanced at Yusuke knowing that his words, while rough, showed the leader in him coming through to the surface. Within the depths of his mind, he heard Yoko snort and wonder with a great deal of amusement how Botan and Koenma were going to answer Yusuke's question. Botan's confidence turned to slight embarrassment as she wrung her hands and turned her head from the inquiring gazes of the Tantei.

"Ano . . . Koenma-sama doesn't have the necessary clearance to view the file, all he has access to is this picture of the girl the day before her 15th birthday which was 3 years and 1 month ago."

Yusuke burst out laughing.

"BWAHAHAHAHAHAHA!"

Embarrassed, and turning a previously unknown shade of red Botan handed the picture to Kurama. While he studied the girl's face and imagined what she would look like now, Yusuke finally got a grip on his laughing fit, his face turning serious.

"Look Botan, tell the toddler I can't do this now. Something's up with my family, I haven't been able to contact them; so I gotta find out what's wrong." His chocolate eyes became windows to his soul that showed his concern as he thought about what could have happened to his cousins, aunts and uncles that would force them into hiding, especially Ranma and his parents who were all powerful martial artists in their own right.

Atsuko Urameshi watched worriedly from the kitchen as her son slammed the phone on it's cradle and cursed resoundingly. Earlier that day he had stormed into the apartment with a sour expression. While that in itself was hardly unusual, it was his intense gaze that bid her to watch him as he picked up the family address book and began dialing. With each call and each negative answer Atsuko could see Yusuke becoming more frustrated, she couldn't help but wonder why he had this sudden need to contact his cousins. And now she wondered why he couldn't find them anywhere.

"K'so!" He swore as his hand hit the wall.

"Yusuke . . ." Atsuko began quietly. "Call this number."

She turned and walked back to the kitchen with a dismissive wave.

Yusuke looked at the slip of paper before he watched his mother pick up her coffee and sip it.

"Okaa . . ."
