Underworld:

Fallen Angel Base:

The scientist smirked as he viewed his latest creation. It was almost complete, there was only one thing left. " Will Raynare please come to my lab? " He spoke through a microphone.

After a few minutes, the door opened, and revealed a panting female. " You called for me, Azazel-sama? " she spoke, as she offered the man a bow.

The man spoke, " Yeah, I did. According to Dohnaseek, you have the twilight healing sacred gear, that once belonged to the nun. Am I correct? " The girl stiffened slightly, then spoke out a short " Yes. "

" Good. You didn't lie, surely you remember her, don't you? " spoke the governor general, as he pointed towards what seemed to be an examination table. The girl followed the man's finger and gasped, for on the table was a carbon copy of the nun, though it just seemed... unnatural.

" This is... Azazel-sama, why did you summon me? " she asked.

" By researching sacred gears, I came to a major discovery: When the bearer of some certain sacred gears dies, a part of their soul is stored within it, that said, the consciousness of the nun might be stored in your sacred gear. " he explained, as he remembered what happened with Vali.

" What do I have to do? " she asked, the man merely smiled, and led her to machine, that had a small opening, the size of an average arm. The girl put her left arm within the machine, and waited. " Are you sure this will work? " she asked, hesitating slightly.

" No. Either way, I do have the girl's memories. " he spoke honestly. He then pushed a few buttons, and after the machine lit up... nothing noticeable happened. "Looks like this sacred gear doesn't keep consciousnesses... " spoke the scientist, scratching his neck, sheepishly.

The weaker fallen gave the man a bow, then spoke, " May I leave, Azazel-sama? " .

" Yes. " spoke the man, as he saw his subordinate leave. " Now that's done, guess I'll try you out. " spoke the man, as he viewed a small data card in his hand.

Occult Research Clubroom:

Riser had just challenged Rias to a rating game, and she was surprisingly calm about it. The girl had then left the room, followed by Akeno. " She's quiet serious about this. " noted Kakuzu.

" Of course she is, as this will affect her freedom. " commented Aimi.

Kiba gave her a nod, then spoke, " We can't even waste a moment. " After a few minutes, Rias came in the room.

" I've contacted Sona about our leave. We will depart tomorrow. " she spoke.

' So, even Shitori is a devil, huh? ' thought Kakuzu. " President, can't we leave today. " he asked in all seriously.

" It would be best if everyone time some rest, as our training location is a bit far from here. " Rias explained her reasoning, to which Kakuzu nodded, and then went out of the room, probably to pack his stuff, or to complete a pact.

Base of a Mountain:

The next day, Rias had transported the peerage to the base of a mountain, which thankfully had proper stairs.

" President, why are we here? " asked Kakuzu, who was carrying a large bag, filled with Rias, Akeno, and Aimi's supplies.

" A villa that my family owns is present at the top of the mountain. " explained Rias, " And the reason you're carrying all of that is because your sacred gear requires your body to be able to withstand stress. " she added.

The boy nodded and started walking. In a short amount of time, Rias, Akeno and Koneko had almost reached the top, with Kakuzu, still near the back, cursing at his physically weak body, and because of the amount of load on him, with Aimi and Kiba near him.

" Yuuto-san, you may join the others. I have to discuss something with Hyoudou-san. " spoke the woman, to which the knight nodded, and then left for the villa.

As soon as he was out of sight, Kakuzu spoke, " So, what did you want to ask me, Kasagi-san? " asked Kakuzu, to which the teacher, boldly spoke.

" Who are you really? ", surprising the miser.

" Oh, and what do you mean by that? " he asked, a hint of curiosity in his tone.

The woman bluntly spoke, " You recognized that Jashinist at the church, even though it's not an actual religion. " hearing this Kakuzu concluded his suspicions about the woman.

" You were a member of the Akatsuki. " he spoke, and the woman nodded rather grimly.

" It's been a long time since we met, Kakuzu. " she spoke, her voice monotone.

" You're Konan. " the miser concluded with furrowed brows. He knew that it couldn't be Deidara, or Sasori, as they would always babble about art, it wasn't Kisame, as he would gladly battle almost any opponent that he thought was strong. Itachi, and Pein were out, as they probably had little to no interest in art, or being slaves. The woman nodded, then spoke, " I'm guessing that Freed was Hidan. " receiving a nod from the miser.

" So, I'm also guessing that you have a strategy or two for Riser. " she continued.

The miser smirked, then spoke, " Well, I could probably paralyse him, and then break his neck, though I'm not sure that it would be acceptable in devil society. " making the female hum.

" Let me guess, you won't do that in favour of the prize money, if there is any. " She spoke, rolling her eyes.

" To be honest, I never thought that you'd be this cheerful, when we first met in you're house. " spoke the miser.

The woman shrugged, then spoke, " Maybe it's because I actually have parents in this world, a family even. " ending it with a smile. " So, how was life for you? " she asked.

" I've found myself a pretty good supplier, and that's about every notable thing. " answered the boy. The woman merely let out a sigh, and spoke, " You noticed that Riser had a family member in his peerage, maybe we can hold her hostage, and force him to give up. "

" That could work. " was all the miser spoke, as he saw the peerage present at the top.

Top of the Mountain:

Kakuzu, along with Konan, had reached the top, with the former mildly exhausted.

" It seems all of us have arrived. " spoke Rias.

Kakuzu nodded, but then his sights were settled on the villa, rather the mansion in front of him. His respect for the Gremory clan suddenly increased.

" Issei thanks for carrying our stuff. You can put it down, it's time for us to change. " she spoke briskly. After her announcement, each peerage member took some clothes, and went to certain rooms to change.

Kakuzu had changed into a gray and white sports outfit, with Kiba wearing a similar one, Rias had worn a red themed one, Koneko was wearing a simple white shirt, with gym shorts, along with knee high black stockings. Akeno had worn a traditional Japanese miko outfit, and the only bishop of the group had worn a simple red shirt, along with deep blue trousers.

" Okay, everyone, it's time for our training to begin. " announced Rias. " Issei, you're going to work on training your reflexes, with Kiba, Aimi will work on her magic, courtesy of Akeno. Also, you're also going to need to strengthen your body. " she continued.

The members of the peerage nodded, and then it split up to do different tasks, Kakuzu, Kiba and Koneko went to a small clearing besides the mansion, the others went to a clearing behind the mansion.

With Kakuzu, Kiba and Koneko:

Signalling Kakuzu, Kiba called him to the actual clearing, and Koneko looked at them with mild interest.

" Issei-san, catch. " spoke the Knight as he created a wooden sword and threw it at the former shinobi, and made on for himself.

The boy caught the blade, and after a few test swings, spoke, " Let's begin. " .

As soon as the words left his mouth, the two males charged at each other. Kiba allowed Kakuzu the first hit, which, in Kakuzu's mind, was a simple mistake. The miser slashed at the blonde horizontally, but it was blocked, however, the miser didn't give him a moment, and continued with relentless attacks, all of which were either blocked, parried, or didn't hit their intended target. The miser gritted his teeth, and threw miniature paralysis spells at the blonde, that went unnoticed.

Kakuzu then started targeting the more vital areas, such as the blonde's neck. After a few minutes, Kiba was easily slowing down. At this point, Koneko had narrowed her eyes and was staring intently.

The match ended when Kakuzu successfully hit the other male's neck.

" I surrender. " announced the Knight, and Kakuzu retracted the sword. " But you used magic. " he continued, when he noticed that his body was seizing up a bit, not much of a problem, but it was distracting.

" You never said that magic wasn't allowed. " spoke the miser.

The blonde let out a short laugh, " It seems that I underestimated you, Issei-san. The spar won't be so easy the next time. " he spoke, his voice honest.

" That's true, however, you also made a another large mistake. " spoke the miser. Seeing Kiba's confused glance, and Koneko's curious face, he continued, " When you face an opponent, go at him with the intent to kill, otherwise, the chance of you losing will be much higher. " his voice full of truth. Before Kiba, or Koneko could say anything, he continued, " Of course it's your choice to kill them or not. "

" Fine, then, but Issei-san, our next spar would be much difficult for you. " spoke Kiba.

" Sempai, battle me. " spoke Koneko, as she walked forward, her gaze neutral. " No magic. " spoke the quiet girl, as she went into an offensive stance.

Kakuzu went into a stance himself, and the two allowed Kiba to step back. As soon as the blonde was out of harm's way, Koneko sped forward, her speed much slower than that of Kiba's, and pulled back her small fist.

Kakuzu prepared himself, and attempted to guard his chest. The punch was blocked, but Koneko seemed to have expected this, and swept one of her legs under Kakuzu's.

In an attempt to avoid it, the boy jumped up. Seeing this, Koneko grabbed one of the boy's legs and attempted to throw him, but before she could do as such, the boy kicked her face, momentarily blinding her. The girl winced slightly, and let go.

The boy then found himself thrown head first into a tree. " You lose, Issei-sempai. " spoke the girl. She was about to check on the boy, but stopped when she heard a groan. " You really pack a punch Koneko-san. " spoke the miser as he sat up, rubbing his head.

" The only way to get past you would be to use magic, or having superior speed. " he summarized.

" Thank you, I'll keep that in mind. " spoke the girl.

With Konan, Rias and Akeno:

Akeno had started training 'Aimi ' and to the surprise of Rias, the woman had actually learnt so much in little time.

" How did you manage to master these spells in only a few days? " asked the King, aware that she had trained with Akeno, almost immediately after the church incident.

" I guess I just have the talent for magic, that's all. " she answered with a smile.

" Ara Ara, buchou's right. Have you been training on your own? " spoke the Queen, receiving a nod from the woman. Her magic potential was extraordinary, though it would require some training if they were to match Riser's peerage...

Unbeknownst to them, they weren't the only one's training.

adislt ( PM ) - The reason for this is because Kakuzu has Issei's body, not his own.

WolkaiserDrake - Thank you, also, that remains to be seen.

dveth - I'll try to take care of these problems, besides, I suggest that you first read every chapter before reviewing.

Bye Everyone!
