Chapter title:Prologue

Chapter number:1/21

A/N: OK guys, here's a new story from me. This will be my "serious story", the one that will have more of a plot than any of the others I'm working on. I hope to write a few chapters before uploading any more of them but at least I have the summary for each planned; 21 chapters including Prologue and Epilogue.

I'm really sorry for the confusing summary but I had no idea what to write, hope it doesn't affect your opinion on this ^.^''

I still have a thing for the three not-look-alike brothers and their dynamics so this will focus on it somewhat… You'll see what I mean once you're done reading the Prologue. I won't get too serious with this, not much angst or anything, no character death or major stuff so this will stay T, but I want to give a try to a true plot that doesn't rely on humor or romance, since all my other stories will be around those genres so… yay for something different?

… Anyway, if you do give this a try hope you enjoy it. This one will be the one that takes longest to update from my stories however, I hope the chapters will be of good length without forcing it and I do want the development to flow the right way so I hope you're patient with me. Also remember English isn't my first language and I don't have a beta reader so, please, forgive me for my grammatical and spelling mistakes.

Without further ado, let's get this started!

Prologue

Blood Pledge Castle was under attack, there were people in long black robes fighting with swords, their fencing level as good as that of the soldiers in the castle. Torches were lit all over the place in order to make it easier for the soldiers to locate their attackers who would, otherwise, get lost in the darkness. The number of intruders was unknown but they were enough to face one on one the building's inhabitants.

Wolfram cursed under his breath as he saw more intruders appear from seemingly no-where: He had to pick this precise night to catch up with some work that had piled up after their last mission and had decided to sleep in his own room in hopes of not waking his fiancé if he joined him in bed so late; he now wished he had gone to the royal bedchambers anyway, that way, he would have been right next to Yuuri when the attack started and made sure he was kept safe. Now, he had to find his King before anything happened to him, he just hoped the double-black was with either Conrart or Gwendal –or Günter at least-; it didn't matter who it was as long as someone was protecting him. He was just glad he shouldn't worry about Greta since she was still studying abroad with Hristo Cruyff.

A sudden movement out of the corner of his eye made Wolfram react immediately to defend himself against the sword aimed for his neck, he was quick in leaving the cloaked figure unconscious. He wasn't sure if the attackers were human or not but Yuuri had never wanted to kill anyone so he did nothing more before continuing his way, hoping to find the Maou soon.

Body after body fell unconscious to the floor as Conrart made himself way through the attackers, calling out for Yuuri in case he was near. He was hoping the King was at Wolfram's side, he knew the blond had been up late due to paperwork but it was likely he had still gone back to the royal bedchambers once he was done, or at least that's what the brunet hoped for, if not, it would mean his godson was alone when this whole thing started and if the Maou hadn't done anything against these people yet then Yuuri could be in trouble.

Trying to think as positively as he could, he kept on going: Wolfram had to be with Yuuri and they were fine, but, still, the number of intruders was so big, he feared Wolfram might need help eventually. The half-breed hadn't seen Gwendal or Günter so far either but he was sure they were okay, same with his mother who was probably with Gisela and Anissina by now defending themselves somewhere. Never-the-less, he had to find his family soon and make sure they were all fine with his own eyes.

Three more rivals made his way to him and he got rid of all three with barely any effort. He had no idea how these figures entered the castle: Guards had been doing rounds as usual, he himself had been walking through the castle mere minutes ago so he didn't know where they had failed. Even now he couldn't tell where they kept coming from but he had the impression the number of intruders wasn't getting any smaller no matter how many of them Conrart knocked out. He just had to keep moving, hoping to get reunited with the current Maou soon; he had the feeling this attack was against the double-black and wouldn't stop until they got what they wanted, whatever that might be, but if anyone dared hurt him then he didn't know what he would be capable of doing.

Gwendal was getting tired of these intruders: They were troublesome and seemed to be endless, he just hoped those he had knocked out wouldn't stand back up. The Mazoku commander grunted as he turned a corner and fought two more… were they even warriors? He had no idea what kind of enemy he was facing, he knew they were good fencers to some extent but he seemed to deal with them rather easily whereas the soldiers he saw fighting around him seemed to have a little more problem handling them but he knew they could manage without his help. It would have been much easier for him to know whether these intruders were actually recovering or not if he could, at least, wound them –any wound would be proof of a previous combat- but the 27th Maou wouldn't allow that and he couldn't go against the king.

He kept on moving, he had to meet up with his family, hoping that at least one of them was with the black-eyed teen… Speaking of which, he was surprised the water dragons belonging to said male had yet to make an appearance considering the whole castle was battling against some unknown enemy and there were a lot of people living in there that the monarch cared about; Gwendal could have sworn Yuuri would have put an end to this by now, should he be worried then? Or is it that, somehow, the youth didn't think it was necessary to attack just yet? Was he just too shaken up to do anything or was he out of combat already? Was everything actually okay after all? What did these intruders want of them?

Another attack came from his right, he quickly deflected the attack and took down yet another cloaked figure, if the situation didn't get better soon he would start losing his temper and he didn't know what he was capable of it that happened. The best he could do for now was focus on finding someone, preferably the king and, at least, one of his brothers, and figure out what to do to get rid of all these people.

Wolfram was getting desperate, it was during times like this that he wished the place wasn't so big; he was feeling completely lost in his own home and he was all alone. He hadn't seen anyone but soldiers in the hallways and he was having trouble remembering the faces of all those men, he couldn't recall a single name from the Mazoku he had seen defending the castle and none of them had said a single word to him or asked to come with or if there were any orders they should follow, it was as if no-one but the intruders had noticed his presence… It was starting to scare him.

He had even used his Maryoku a few times already but no-one else had, not even the intruders but they didn't have Houseki either so it was unlikely they came from human lands. After walking and fighting for Shinou-knows-how-long and never getting anywhere near Yuuri's bedroom as far as he could tell, Wolfram was wondering if his mind was playing tricks on him since he could not pinpoint where exactly in the castle he currently was and he had seen no-one around use their element even though he could feel some Maryoku left-overs when he walked down a few hallways. What was going on exactly?

"Yuuri!" The blond called for what seemed the thousandth time, still hoping to hear his fiancé calling back to him so he could have one less person to worry about "Yuuri!"

The more he advanced the worse the feeling of loss got, at this point, he would take anyone he knew to appear before him; he just wanted something to tell him he was on the right path and that there were more people around him he could recognize and who actually acknowledged him, something that could make him feel like he wasn't alone in this mess.

"Wolfram!" The fire-wielder turned around trying to find the source of the voice and attempting to match the voice to a face but came up with nothing, he had no idea who that voice belonged to but whoever that was they were calling out to him and he had to help them so he broke into a sprint with sword in hand, ready to attack if it were necessary, this time, he would use the sharp edge; he was tired of fooling around with the enemy already and he could only handle so much.

He stopped suddenly at an intersection, hearing hurrying footsteps in front of him and to his left; they were trying to play smart attacking him where four hallways met but he was ready for them. The cloaked figures became visible and Wolfram jumped aiming for the spot where the neck met the shoulder of the attacker that came from the front to finish him off first knowing he might get a wound from the other enemy but trusting he'd be fast enough to avoid anything fatal, his arms raised to gain impulse and he brought the sword down-

"STOP!"

Wolfram's eyes opened, his body halting to a stop. His mind was blank and he could not figure out where he was or what was happening around him, his head was spinning, he was panting and the only thing he was aware of was his hands holding tightly onto the handle of his sword, his whole body was tensed up.

The blond took one deep breath, trying to calm his heartbeat and get his breathing back to normal, and felt his senses returning slowly. He felt silk against his skin and cold air brushing his calves while his bare feet rested against a solid surface, then, he noticed his surroundings were kind of dark but shadows danced on the walls cast by flickering lights, there was also people looking at him as if startled by his presence… He recognized those people: There were guards he greeted every morning and could name them all, Günter was standing by them wearing his light blue nightgown with the matching nightcap, there was also his mother in her very-revealing negligee holding a hand to her chest, Anissina stood behind her with Gisela next to her and, then, there was Yuuri in his usual blue pajamas but no usual smile on his face; just wide, scared black eyes.

The fire-wielder grew more aware of his surroundings and felt something right above his collarbone, turning his head slightly, he saw a blade shining under the lit torches –the flickering lights he had seen earlier-, his eyes followed the blade up to the cross and then the handle to a pair of lightly tanned hands, up yellow-clad arms and to a familiar face wearing a foreign expression. He looked at the brunet, eyes full of shock staring back at him, although, he was sure they were but a mirror of his own.

A flash caught his attention, something was hovering next to Conrart's neck; it was another blade. Following the same path with his eyes as he had beforehand, he recognized the big hands and wine sleeves before he saw his oldest brother's face, Gwendal's eyes glued to their half-breed sibling as if not believing what he was seeing. A moment later, those cobalt orbs turned to lock with Wolfram's emerald ones, the young Bielefeld felt the movement of the other male's neck through his arms and that's when he realized Gwendal also had a sword pressed to his neck and it took him just a second to gather that he was the one holding that third sword.

"What's going on here?!" Yuuri asked the former Maou's three sons who, all at once, dropped their swords as if the handles burned them. The three males looked around them, waking from the trance they had been in a minute ago, registering everything that was there. Finally, turning to their monarch, the three of them spoke in unison:

"I don't now…"
