Prologue:

The atmosphere in the room was too gloomy for keiko's comfort. She knew, the moment Koenma appeared-Botan in tow-that there was something going on in the human world, and without a doubt related to demon world, which do nothing good to her queasy nerves.

She glanced at the person sitting beside her.

"Yusuke.."

She murmured the name of her half demon boyfriend. She wanted to ask him if 'everything is okey.' and then he would face her and send his famous cocky grin and assured her that 'everything is going to be fine, because he's just going to kick anyone's ass if ever they try something to harm anyone that he cared for.' and then she would feel better, and her heart would finally stop drumming nervously inside her chest.

But that was not the reply she received once Yusuke glance at her.

She could clearly see the seriousness reflecting over his brown eyes when their eyes locked with each other.

Eyes that usually filled with mirth and mischievousness were now replaced by a sharp edge and hidden anxiety regarding the situation they had in hand, in which, she still didn't know of.

He gave a squeeze to his girlfriend's hand resting on his arm, but said no words of comfort or cocky remarks. Making it obvious to Keiko how much grave the situation they had.

Keiko accepted that. She accepted the fact that even though her boyfriend was one of the most powerful being living on earth, he still had something that he fears and that he was not much as an invincible person as a lot of demons thought he was, but that didn't stop her heart to increase its beating, pounding erratically inside her chest as nervousness vibrated throughout her body.

Keiko looked around the room, realizing that all of the disbanded members of the former Reikai tantei were all present now.

Kuwabara Kazuma, sat opposite of her, reflecting the same seriousness she saw in her boyfriend's face a few minutes ago. Eyes filled with seriousness that she once saw during their escapades as Spirit Detectives back when they were in Junior High.

Beside him sat Yukina, sitting there quietly, looking clueless just like Keiko. Yukina's eyes were shifting from her boyfriend to the other people occupying the room.

To Kuwabara's left side sat Youko Kurama, the fox had a calculating gaze, a grim expression was clearly visible over his handsome face, adding a tenfold of anxiety over Keiko's chest.

Kurama usually the calmest of them all, though he always had a calculating look hidden over his calm exterior in situation like this, but the edginess over his emerald eyes was somewhat different from his usually calm demeanor.

To Yukina's right side sat Botan, looking calm at first glance, but one couldn't hide the feeling of nervousness with an atmosphere as heavy as this.

Botan's eyes were shifting, looking at the people around the room, and she was fidgeting on her seat from time to time.

Sitting beside Botan was the Prince of Spirit world in his teenage form, Koenma, having the same solemn expression over his face like the others had.

Across the table, sat Genkai, and opposite of her, to the other side of the table sat Shizuru, with a cigarette between her pointing and middle finger.

Keiko's eyes landed to the final member of the group. The all quiet and grumpy fire demon, Hiei. Sitting on his usual spot over the windowsill. Looking solemn, though at first glance, he looked like his normal grumpy self, but when one look closely,his tense posture gave him away.

What confused Keiko the more regarding this set up was their presence in here. She, Yukina and Shizuru usually were not a part of any kinds of meetings such as this. Especially when it was about demons, spirits and human psychic's affair.

Before Keiko could voice out her concern, Koenma spoke.

"As most of you know, a disturbance happening over the Makai recently caught our attention."

Koenma said, pausing for a moment as if collecting his thoughts. shifting his eyes towards Yusuke, he addressed him.

"Yusuke, have you discovered something in tourin?"

Everyone's attention focused on Yusuke, Keiko saw, as a frown itched over his face before speaking.

"It was subtle, but I sense a strange kind of energy spiking from the south. We investigated it further but found nothing. Then suddenly, demons of different species started disappearing in my territory."

Yusuke said, displeasure clearly plastered over his face.

"Same thing happened in Gandara."

Kurama stated, catching their attention. He laced his fingers together, eyeing them seriously as he speak.

"Yomi contacted me a month ago, asking for my aid regarding the strange spikes of energy to the north side of Gandara, and as I continue investigating, I found nothing, but then, demons in Gandara are also disappearing without a trace. Some are not just ordinary demons. I tried sniffing the air...and.."

Kurama paused, looking deep in thought, as if he himself couldn't comprehend the conclusion he had come up with. Fortunately, Hiei beat him to it.

"..there are traces of humans hovering around the air.."

Hiei said with a monotone voice.

"We have encountered the same problem to the west side of Alaric, I tried looking for a trace, but even with the help of my Jagan eye, I still ended up with the same information as Kurama and the detective."

Hiei stated solemnly.

Tension filled the air after he said that. The graveness of the situation was finally down in every occupant in the room. If Hiei couldn't find anything with the help of his Jagan eye, then what and who could help them? As far as Keiko knew, nothing could escape the fire demon's eye. Even Reikai didn't know what was going on.

"b-but how can that be possible? Ordinary humans can't stand the air in the demon world, let alone go deeply in every territory of Makai without alerting the higher ups, and as far as I know, the only place in Makai that humans can go without easily alerting anyone are the borders around it, powerful psychic or not. So how can humans go deep in Makai and do something like this under our noses?"

Botan bursted out in frustration. Disbelief was clearly written over her face.

"We don't know."

Answered Kurama towards Botan's question.

"I tried following the scent, and then, it just suddenly vanished. The scent stopping completely..as if..."

"..as if entering a portal."

Genkai finished for Kurama.

"..but I am sure that every portal towards Ningekai has been sealed, and we already investigated all of those ending trails, searching for the place where a particular passage from Makai to ningekai exist, and all of those supposedly portals didn't have any connections or entrances to the ningekai."

Koenma countered, a deep frown over his face.

"..and still, a number of missing demons are increasing, day by day...and now, a few weeks ago, I found out that ten powerful psychics are reported missing."

Genkai said solemnly.

"it only means one thing..Whoever it is that we are dealing With.."

Kurama gravelly stated, faltering at the end. There was a conflict swimming in the eyes of the fox demon, as if he refused to accept the fact that what was happening now was out of their control.

"...Are coming in ningekai now."

Kuwabara concluded, finishing what the fox had failed to finish with a look of horrified realization.

"damn it!"

Yusuke hissed through gritted teeth. Anger screaming over his system. There were a lot of important people living in ningekai. Like Kurama's human mother, step brother and step father, Keiko's family, Yusuke's mother and many others. He didn't want to think of what would happen if one of them loss a love one because of this unknown threat.

"it's like somebody is toying with us-"

Before Yusuke could finish his angry statement, A flash of dark light occurred on the ceiling of Genkai's temple, right above their heads.

"What the fuck!"

Yusuke cursed loudly.

Before Keiko knew it, an arm was encircled around her waist and she was lifted from the tatami she was sitting on.

The next thing she knew, her face was flushed on Yusuke's chest, his hand securing her head over it, and an arm wrapped protectively around her waist. She looked around, everyone had jumped away from the table. Kuwabara was shielding Yukina, and Hiei standing beside him. Kurama stood protectively in front of Botan. Genkai, Shizuru and Koenma were all bucked into a corner. Everyone's attention were focus on the ceiling. Tense and rigid.

Keiko's heart was literally on her throat. She glanced at the ceiling, almost afraid to do so.

What she saw caused her to grab unto Yusuke's shirt tightly as if it was her lifeline. Squeaking a nervous and high pitched "Y-Yusuke!"

Yusuke tightened his hold around his girlfriend, eyes never shifting away from the ceiling, an angry snarl falling from his lips as he glared up towards it. Waiting for someone to come out from it for him to quickly take care of it.

If Yusuke still had his heart, it would without a doubt beating erratically inside his chest. Because even though he was one of the most powerful being living on earth, he still couldn't deny the fact that they still didn't have enough information about who they were dealing with, and in his years of adventure, he learned not to engage in any kind of situation without having enough information. Yusuke had matured over the years and learned who were the people he prioritized in his life, and those people were mostly present in this room where a portal suddenly appeared, and he didn't even know who will come out from it. Yusuke was frightened. Not for his life, but for the lives of his most important people.

He couldn't afford to lose any of them.

Over the ceiling, an endless void of black light had suddenly appeared and now slowly expanding on its size.

"It's a portal!"

Shouted Kurama. Before anyone could move. A feminine screeched was heard coming from the portal followed by a snarl and then a small girl, about the size of Yukina went tumbling down from the portal followed by another figure, a male. The two fell over the floor ungracefully with a resounding 'oof!' and ouch!' Limbs entangled with each other.

Yusuke moved, his face contorted into a deep menacing snarl, opening his mouth to demand answers from the two figures who fell from the portal, but before Yusuke could let Keiko go completely to confront the two intruders, another figure came crashing down from the portal, falling with a loud 'thud' on Genkai's table.

There was a grunt of pain and then silence.

All the occupants of the room stared with widen eyes at the girl sprawled on the table who was bathing with her own blood.

Blood coming from her body, soaking her white shirt and pants.

Her long, dark grey hair was stained with blood, covering almost her whole face and her heavy breathing was resonating all over the room as the girl's body twitched.

No one moved.

It was so quiet you could probably hear a pin dropping on the floor.

..and then the bloody girl, with much effort to her part, slowly lifted a hand towards the portal, before anyone could move, she firmly fisted her hand and the portal disappeared like a bubble on the air. After doing that, her hand dropped limply on the table.

A beat

the girl lost her consciousness.

and all hell broke loose.
