Having left Kyoto a month ago after spending some time with Yasaka and Kunou, though he felt his heart constrict at leaving the woman he loved and their daughter again. Damian sat on a small rock in front of a campfire he made, cooking some fish he caught from the nearby river. The sun beat down in the sky with very few clouds being present in the sky. It was a pretty nice day in his view.

Damian was not far from a small town named Kuoh, so he might pass through or stay in the town for a couple of days before moving on. Maybe he'll investigate the Devils and Fallen Angels he can sense within the town. None of them were on the level of a High-Class Devil, so they wouldn't be too much of a threat or challenge. He was also aware that Kuoh was the territory of one of the Devil families but wasn't sure which one.

If things ended in a confrontation, Damian knew he'd handle it quickly.

As Damian watched his fisk be cooked, his sharp eyes snapped to the bushes as they rustled before a black cat with amber eyes came out, sniffing before it looked at him and tilted it's head. The cat then saw the fisk that was cooked and stared at it hungrily. Damian glanced back and fourth between the fish and cat before he sighed and picked up the cooked fish.

"Come on." He said, putting the fish down a few feet in front of the cat. The cat edged forward warily, as if thinking it was some kind of trick, but it's hunger must've taken over because the cat was quick to bite into the fish and start feasting on the meal. Damian tossed another fish to the cat and watched it devour that as well. "You must've been very hungry."

Once the cat had its fill, it came over to Damian and rubbed itself against his legs while purring. Damian smirked a bit and scratched the cat behind the ears, getting louder purrs in response. He kept it up for a few minutes before he picked the cat up by the scruff of its neck and held it in front of his face, seeing the confused look on the cat's face.

"So, care to tell me why you're here, Devil?" He asked with a more serious tone and saw the cat's eyes widened. "you might be able to turn into a cat, which means you are a Nekamata, but I know a Devil signature when I sense one."

Before anything else could happen, both sensed a new power appearing not too far away and begin coming in their direction. And from what Damian could sense, this was someone very strong. Damian looked at the cat and noticed it was shaking a little in fear before he sighed and placed the cat down, gesturing to the tent he had set up nearby.

"Get into the tent and stay there. I'll deal with this." He ordered. All he got was a stare in return before the cat purred at him again and quickly sauntered into the tent and disappeared from site. The tent was magic, appearing bigger on the inside, so the cat would have many places to hide and not worry about someone peeking their heads in as if it was a normal tent.

Damian sat back down on the rock and just waited. But he didn't have to wait long before a man came out of the forest. He was a tall man appearing to be in his twenties with an average build, black hair, golden bangs and black goatee. He wore a V-neck maroon long-coat with a wide, open high-collar that opens up at the hem. The long-coat also featured two black belts around the waist and four black bands on each arm, two of the bands at the wrist and the other two near the elbow. He wore grey slacks and brown shoes.

"You are a hard man to find." The man said with a grin. "Two hundred years of being on the move made it difficult to track you."

"And how exactly did you manage to find me... Azazel?" Damian asked, narrowing his eyes at the Twelve-winged Govenor of the Fallen Angels.

Azazel puffed out his chest. "The Grigori have spies in every country on the planet. One of my guys felt a rather powerful devil signature appear a few weeks ago by chance in Kyoto. It took a while and a lot of magic tracking but we eventually managed to find you."

"Hmm." Damian sounded as he eyed the Fallen Angel cautiously. They weren't friends or enemies. Damian wasn't like other members of his kind where they'd see every Fallen Angel as an enemy just because they are Fallen Angels and the natural enemy of Devils like the Angels of Heaven are. The only way to become Damian's enemy is to target him, the ones he loves, his home, stuff and people he cares about... or piss him off to the point he wants you dead.

While the man was strong, it was his mind and tactics that many had to keep on their toes around. Before he fell, he was one of Heaven's best and would have been a Seraph if he had not given into his desires and sins.

"The last time I saw you, you kicked my ass and buried me into Mount Fuji. It took me two days to dig my way out of that volcano," Azazel said with a pout.

Damian ignored the stupid look on his face and flat out asked the man. "What do you want?"

"Can't I visit and talk with an old friend?" Azazel asked but got a glare in response from the grandson of Lucifer, making Azazel sigh. "You are similar to your grandfather it scares me." His tone changed to a serious one as he spoke. "In the last decade there has been a group beginning to form that could very easily pose a threat to not only the Human World but the Underworld and Heaven as well. This group is a little different from the other sort of groups or factions that have been put together in the past."

Damian was silent as he listened.

"The group is not just solely one species but made-up multiple divisions, each which has a different species of creature occupying it. Fallen Angels, Devils, Strays, Magicians, Yokai. You name it they have all joined this group." Azazel said, before his eyebrows lifted as Damian chuckled.

"You're talking about the Khaos Bridgade." The Mammon heir stated more than asked.

Azazel gave him a look of surprise. "You know?"

Damian scoffed. "Did you really think I wouldn't know about such a group forming? Only fools would take no notice of them."

"But HOW do you know of them?" Azazel asked.

"They asked me to join." Damian said coldly as he stood and looked out at the view of the light. Azazel's eyes widened as he began to cautiously eye Damian.

"And what did you say?" He asked suspiciously and slightly with fear.

"I said no." Damian said with a scoff. "I could care less about whatever their agenda is, so I told them to go to Hell and when they didn't take the hint... I killed the ones who came to me and sent their heads back to whoever their leaders are."

Azazel nodded, He had been worried there. He knew how strong Damian was, being the grandson of Lucifer himself. If he was to join the Khaos Brigade, which was already filled with many strong beings, they'd be unstoppable. However, he knew he'd have to keep an eye on the Devil just in case he was lying.

Decepticon was in the Devils' nature.

"Does anyone else know?" Damian asked but Azazel shook his head.

"No, but I think your old buddies, the Four Satans, are starting to take notice of the group's actions." Azazel said. "I have noticed Sirzechs and Ajuka sending some of their peerage out more and more lately on recon missions. The actions of the Khaos Brigade are beginning to get noticeable."

"Not surprising." Damian said, his arms crossed. "And how is my former friend? Backstab any more friends lately?"

Azazel winced at the bitter tone he spoke in, mentally fighting over whether he should tell him about a certain piece of information. It was not known publicly around the world, but many higher ups were aware of the situation between Damian, Sirzechs and Grayfia.

"What was the last you heard about Sirzechs and Grayfia?" Azazel asked and noticed the twitch in the Devil's hand when he said her name.

"Only that he and Grayfia were living a happy life as the mighty power couple of the Underworld." The sarcasm was evident in the Devil's voice along with a hint of anger, hurt and bitterness. "About fifteen years or so I think."

"Then you should know they had a pretty big life changing experience ten year ago," he said noticing the Devil's attention was now firmly on him.

"And what would that be exactly?" Damian asked trying to keep his emotionless mask on his face.

Azazel sighed while rubbing the back of his head before he spoke. "They had their first born ten years ago. A little boy I believe."

Damian stared at Azazel coldly for several seconds before turning away. "I see... Sirzechs sure it's his? I wouldn't be surprised if it turns out Grayfia went and spread her legs for anyone behind Sirzechs' back... what's the kid's name?"

"Millicas Gremory."

"Hmm... a okay name." Damian muttered, running a hand down his face. He then turned to Azazel with narrowed eyes. "Getting back on topic, why are you here? I doubt you went through a lot of trouble to find me... only to tell me about the Khaos Brigade."

"Well, two things really. The first is to tell you that the Old Satan Faction may get involved with the Khaos Brigade." Azazel said, causing Damian's eyes to narrow.

"Then I'll finish what happened and end them for good instead of sending them cowering into their little holes." Damian said coldly.

"Yes, but even you can't do it alone." Azazel told seriously. "From what I can tell they will target the Underworld eventually. Whether its people or land a new potential war is brewing…The Underworld will need you."

"...We'll see. And the second reason?"

"I need your help." Azazel said, making Damian look at him and give him the gesture to go on. "I sent a group of Fallen Angels into Kuoh town, the territory belonging to Rias Gremory and Sona Sitri. Their mission was to keep an eye on a boy with a Sacred Gear, one that I think may be the Red Dragon Emperor."

"And how does this require my help?" Damian asked with a raised eyebrow.

"Well, they've stopped reporting to me which is naturally suspicious since they were supposed to report twice every month, and they haven't done so in two months."

"So why do you want my help?" Damian asked.

I sent a group of Fallen Angels to the town of Kuoh, to keep an eye on a boy who may contain a powerful Sacred Gear, but they haven't reported back to me in weeks, and my own spies reported the boy being killed when I ordered him to just be watched over, and now he's a Devil under Rias Gremory. I was wondering if you could go and sort it out for me and bring them back alive, and if you can't bring all four back... try and bring at least one or two of them back."

"You suspect they've been led false information?" George asked with furrowed brows.

"Perhaps." Azazel said. "Wouldn't be surprised if Kokabiel was behind it. He's been getting awfully suspicious lately with his desire to restart the Great War between the Angels, Devils and Fallen Angels. Hey, I'll make it worth your while."

Damian raised an eyebrow. "How so?"

Azazel's grin turned perverted. "You bring Raynare and Kalawarner back, who are two hot babes with big breasts, and I'll let you keep them. Later!"

With that, he spread his twelve wings and took off, leaving a very annoyed Devil behind.

Damian growled. "Fucking bastard."

He turned and walked into the tent. The tent itself was a magical tent meaning it was a lot bigger on the inside. While outside it looked like a simple four-person tent, inside it was as big as a four-bedroom house with a small kitchen with warm colored carpet, mats and furniture. There was even a bathing area.

"So Nekomata, I hope you have some answers for me and tell me just who you are." He spoke as he looked over towards one of the bedrooms and saw a cat shadow figure run along the white sheet.

He then watched as the cat grew and took on a human shape in the form of a very beautiful woman standing before him. Just like the cat form she was using, she had long black hair and golden eyes. She was wearing a tight, black kimono with a red interior and a yellow obi that accentuated her large E-cup breasts. She was also wearing an ornately decorated headband and a set of golden and black beads around her waist where her kimono had an opening, showing off her long, smooth legs. Something interesting about her was the pair of black cat ears and tails that were swaying behind her.

The woman gave him a cheeky wink. "Thanks Mr. Devil, I owe you one, nya~!"


And that's it for this chapter everyone. I hope you liked it. I've decided to just make it a harem of seven women, mostly one of each species with the exception of Raynare and Kalawarner because... why not?

Harem: Yasaka, Kuroka, Serafall, Gabriel, Tiamat Raynare, Kalawarner.

If you want more, I may put it at 10 women max, but right now... my mind's made up on seven women and that should be enough. A Kitsune, a Nekomata, a Devil, an Angel, a Dragon and two Fallen Angels.
