Eien looked through his new magic book, his eyes scanning at every little thing, hoping to learn it all. It turned out that there was actually another library in the castle that had books on magic and things, instead of dead people's lives. This library was heavily guarded at all times and the only ones who were able to open the books were Sasori and Eien, because the Devil created the book, so only the Devil's blood could use it. Though Sasori added a few things to the book his Father made, he let his own son have a look at it, but not try anything just yet; things could backfire.

After a few hours, Eien had to stop his reading when he realized it was time for another training session. This had been going on for a month now and he felt his body being mentally sore. Though besides that, he actually enjoyed fighting, it made him have a quicker wit.

Sighing, the redhead teleported to where the simulation room was, but instead of his Father, it was just Yoru. "I'm sorry, my prince, but the King is very busy today. Did you know another war started? He told me to tell you that once training is done that you head right too him."

Eien sighed in irritation. "What happened to all of his assistants? They were there for a reason."

Yoru stared at the redhead impassively. "Many of them gave up their lives to fight for your Father when Jashin invaded. He is still recruiting more, but it's getting hard to tell which are spies and which are actually loyal demons wishing to serve their King. Though, he can make demons that would be too risky," He said quickly, answering Eien's next question. "It was risky enough for me to become a demon."

The sixteen year old gave another sigh as he prepared himself mentally. "Why is that?"

Yoru almost smirked. "A soul turned into a demon by the Devil himself is very powerful. Have we not talked about this, my prince? I really am one-of-a-kind. Why do you think the King chose me to be your servant?"

Eien shrugged. "Because you're old."

The demon chuckled. "No, I am the only demon of my kind, well elemental, I suppose. The other two that were created by the Devil himself are Hiruko and Sandaime, though they aren't elementals."

Eien suddenly became engrossed in the subject. "So there are other elementals like you?"

Yoru nodded. "Though none as powerful," He said pridefully as he stuck his nose up in the air with a smirk. "I know of three other elementals, but they are only a few hundred years old. One water, another ice, and one fire. I am the only wind elemental ever." This time he swished his hair and Eien rolled his eyes.

"What's the difference between ice and water?"

Yoru smirked. "Oh, there is a difference, my young prince."

"Well, I think that's enough demon knowledge for now." He readied himself and Yoru didn't even bother for a warning as he went after him. Eien saw the wind swirl around Yoru and his eyes turning silver. He concentrated on his aura and also charged after him. He threw a punch out that was powered by his aura, but in that instant the demon turned into the wind and Eien punched right through Yoru's chest. He pulled back as the demon went to strike and he made sure to jump out of the way far enough. "Isn't that cheating?"

Yoru didn't answer as he went again. Eien sent out his aura to attack in spikes but it went straight through him again. The demon smirked. This was going to be a long training session.

-Later-

Eien sighed as he sat down in his throne next to his Father. "Rough?"

The younger redhead shook his head. "More like boring. All I did was dodge and try to hit Yoru, but he cheated and turned into air." He glared at his servant who was smiling happily at him. "I heard you needed me," Eien said, turning back to his Father who nodded.

"As I'm sure Yoru has mentioned, a war broke out and I still haven't recovered from the loss of assistants, so most of the work will be on our shoulders."

Eien nodded his head and a queue of souls filled the room. He and his Father judged one soul at a time even though his Father could do more, he kept a steady pace and saw their life story flashing in them. They weren't all just soldiers who died in the war. There were women, children, and even men who were also casualties. And the ones that were soldiers all had different stories. Family's needing money, blood lust and hatred for the enemy, having nothing left, and many other scenarios.

Eien had never seen a war or heard about it before so when he saw all the memories in the souls he was mortified. Why would so many people do that just to protect their land? Or even their rights? It seemed to strange that they would risk their life for their nation. He never felt anything like that before, probably because he didn't consider Earth his real home anymore, even though he was born and raised there.

Soon there were angry souls and they began to fight with others, and being there weren't enough demons to help with the riot, Yoru stepped in and calmed the situation. It was like a knife of wind cut right in the center of the mob and screams filled the air. Their actual being wasn't really harmed, but they still felt the pain.

Soon the fighting died down so Sasori and Eien could continue.

-Later-

Before Eien would see the next part in his Mum's book, he had to do something. Go somewhere. There was a place where the souls who have sinned terribly were tortured, atoning for their wrongdoings. Tartarus was one of these places, but another was similar just not a pit in the ground.

Eien came to a sort of building where these souls were tortured. It was almost like a prison, or dungeon but they would never leave, though some would 'die'. He walked through the door and heard the wails and screams of all the tortured and pained souls. He tried to ignore them the best he could, knowing the deserved this, but how could he not feel bad? He had put some of these souls here, even though it was for a good reason. But now, he was only there for once reason.

He kept on walking till he found the right 'cell'. Since they were short on demons only a few souls could be tortured at a time and this one was lucky to have a break. The soul was a deep red, and Eien remembered it being so much more vibrant, but years of torture would slowly kill a soul till it no longer existed. Eien was even told a few souls would last a hundred years before actually fading away. This one looked like it had been tortured for almost one-hundred years, but knew it was around eleven. Then again he remembered it being given a sentence which lasted an eternity, but it seemed the soul would sooner or later die, but not anytime soon.

"Do you know why I have come?" He asked the soul, who just sat in his corner his legs pulled up to his chest with his face buried into the his knees. He shook his head and Eien tried his best to restrain himself from attacking the soul. He wouldn't do it. He wouldn't finish off this pathetic creature; it would just be a blessing to him. "Do you even remember me?"

The soul slowly nodded and looked up with a mix of black and red eyes. "Yes, I do..."

Eien clenched his hands into fists. "I have a question... Why?"

Slowly the soul looked up fully, showing a fair face. "Why what?"

The redhead could feel the anger boiling through him. "You know what! Why did you kill him?! Why did you kidnap us?! Why did you make my life a living hell from that day on...?!" Eien could feel his nails biting into his flesh and he swore that angry tears would come to his eyes.

The soul looked away. "You knew that she was a man..." He pondered. It seemed even his mind had gone a little. He looked back at the redhead. "You two were nothing more than filth. I took what I wanted, simple as that, even if it was filth."

Eien felt his aura rise, but it turned red. That was why? Because he was able to keep them, he did? Ever since that day he was always depressed and morose. "Why did you take his life, then? Because you could?"

"He... he would have told my secrets. He had to die and... he didn't deserve to live," The soul spat out with disgust.

Eien's aura began to flare wildly. Ever since the day his Mum died, he had gotten worse. He didn't let his Father know, but he would have probably killed himself if he wasn't there to stop him. Each day with his Mum gone was a greater hell than he would ever experience. And he died because he "didn't deserve to live".

The tears never came, but the scream did. He didn't want to hear anymore from the soul. He didn't even move a muscle as he beat him to a near second death. He was screaming more questions, not expecting answers. This wouldn't bring his Mum back, but he wanted revenge. Almost enough to kill.

After a few hours had passed, Eien stopped from using up almost all of his energy. He left the cell and the near-dead soul, so he could go back to the palace. He didn't have enough energy to teleport so he walked to his room, ignoring his Father's questions about his spiked energy level. Yoru didn't even bother him so Eien walked to his room alone.

Once he got there, he collapsed on his bed and closed his eyes, finally letting the tears pass the barrier he was holding up.

No memories in this one! Revenge!

Fairy Tail songs! Y U do this to me?!
