Training to Rule

It was the next day and Filius had woke up earlier than usual, he had a request he needed to ask one of his guardians.

He along with a maid that was escorting him, were currently walking to the entrance of the 5th floor of The Great Tomb of Nazarick. Filius was here to start his training, he had talked with Demiurge and asked him how he could master or test his unknown abilities. Demiurge had suggested that, since he was the son of the Supreme Being he would need to test abilities with the highest level resident. But in order to master things he would have to do them separately, training physical combat with Cocytus and Mare with magic. But if he wanted real combat experience in both he would have to battle Shalltear or Rubedo, though Rubedo could easily lose control. So that left, by default Shalltear.

"Lord Filius, what are we doing here", asked his personal maid.

"I need to speak with Cocytus, and I decided I should see his home", Filius lied.

The maid didn't say anything, she believed that if she said something she would offend her master's son.

The door to the 5th floor opened and they both walked in. The room was something else, everything was encased in ice or so it seemed. If inspected closely you would notice that the wall, the pillars were all made of never-melting ice. They shined like gems, though it didn't take away the frost effect. Since everything was ice the room was cold and the frozen pits of Niflheim.

Filius continued walking, he then approached another door, as he took another step the door opened by itself revealing on the other side two maids that opened the door.

They quickly noticed that it was the young lord and bowed, "Welcome Lord Filius."

"Hello, please call Cocytus for me", as Filus said this a maid stood up and left to his request.

"Lord, do you want to wait for him in the waiting room?", Cocytus's maid asked.

"No, I'll be waiting in the fighting arena, let him know I'll be there", he said as he started walking to the fighting grounds.

"Young lord, what are we doing here?", the maid asked.

"You'll see", he said with a smirk.

After a while, the two maids returned with Cocytus, "Young. Lord. Why. Are. You. Here?"

"I came here to give you orders", Filus then proceeded to unsheathe his sword, "I order you to help me train in the art of combat like a true warrior." His sword was a beautiful katana, the level of the sword was maxed out since Momonga and HeroHero made it that way.

"Young. Lord. Are. You. Sure?", Cocytus asked in a worried tone.

"Cocytus, I wouldn't be asking you this if I wasn't sure", Filius then positioned himself in a typical kendo stance.

"But. lord?", he was then cut off.

"Come on Uncle Cocytus!", Filus teased. He remembered what Demiurge told him about Cocytus's uncle fantasy.

Cocytus went all cutie and nodded without hesitation, "Alright then young lord"

Cocytus took out his own katana and held it in a samurai stance, "Question. Young lord. What. Is. It. That. You. Want. To. Learn?"

"I want to go over everything, every technique, and every style. You'll be the teacher here", Filus grinned.

"Well. Let's. Get. A. Sparring. Match. To. See. Where. You. Are. At. In. The. Scale.", Cocytus said.

"Couldn't have said it any better", both Filus and Cocytus were staring at each other.

Filius then made his move, he charged at high speeds towards Cocytus and swung his sword aiming for the shoulder. Cocytus was surprised by the young lord's speed he quickly moved his sword to block the swing. When both swords hit the floor beneath them cracked and there was a slight shock wave.

"Wow!", the maids said in unison.

They were shocked seeing how much power the Young Lord and Cocytus had, they weren't even fighting with all they had. Filius then went for a kick, it was a low sweep, this surprised Cocytus as he didn't expect that Filus would be willing to fight like an adventurer. Cocytus tripped back a little and Filius tried swinging his sword once more but was deflected by Cocytus's short dagger.

"I. Hope. You. Aren't. Mad. That. I. Am. Using. A. Secondary. Weapon. Young. Lord", he said.

"Not at all, the more the merrier!", Filius once again charged at Cocytus, and all their weapons met creating sparks. Cocytus pushed Filius back and then tried attacking, but it was blocked by the peculiar block Filus had. Cocytus tried swinging downwards but Filius blocked it with his sword and then slid it off to the side of his blade. He then had an opening and swung at Cocytus. Cocytus quickly moved his dagger in front of Filius's face while Filius's sword was on his neck.

"It seems we are in a draw", Filius smiled.

"No. Young. Lord. This. Was. Your. Victory.", Filius knew that he would try to praise him for something like this.

"Cocytus it's ok, I know you weren't trying too hard on me either so it's ok", he said as he placed his sword back in its scabbard. "Now that you have seen my abilities what do you think of it", Filius asked in a chirped tone.

"I. Believe. That. You. Have. So. Much. Potential", Cocytus exclaimed. "Though. There. Are. Still. A. Few. Things. That. We. Could. Improve."

"I'd expected that", Filius then positioned himself in a tai-chi battle stance, "Now let's start!"

Cocytus smiled, though his facial expression didn't change at all, "Let. Me. Teach. You. Every. Thing. I. Can."

That afternoon was full of training in physical combat for Filius. He was taught so many things like reading your opponent's next move, fighting with only your ears, even fighting a weapon barehanded. This was just the first day, they arranged when they would meet. Cocytus was going to show Filius the various forms and styles of fighting that he could learn, from there he would learn their way of battle. Filius was excited for learning more, another thing he learned especially was that when in a serious death battle never play of toy with your opponent. When a death battle commences, make sure to attack and never let up.

Filius smiled and thought about his father, "I'll make you proud and become like you."

Filius quickly jogged to his next destination, it was the 6th floor, where there was two elf guardian he going to meet them. He entered the floor and was immediately met by two maids.

"Let Mare, Arua know that I am here to see them", Filius asked one of the maids.

"Yes sir, Lord do wait in the waiting room?", she said.

"Yeah", they then directed him to a room, one of the maids left to tell the guardian while the other one served him tea. After a while, he heard some running when suddenly the door opened. Arua and Mare quickly came and sat in front of their young master.

"Lord Filius, you should have called us to meet you instead. We would have gone at your beck and call", Aura stated as Mare nodded his head in agreement with his sister.

"Nonsense, besides I was busy, it would be better to meet you instead of making you wait", he said with a smile. "Sit, I have something important to discuss with you two"

They both sat down, "What was it that you wanted to speak about?"

Filius smiled at both of them once more, "Don't worry it isn't something problematic. You all know that my father is the all-seeing and supreme lord of our home. My objective is to continue that lineage, he deserves it, though since he is an undead he can't give birth to another child. So I plan to make that future for him, but I need to get stronger before I do that. I know that Mare is the strongest magic caster of all Nazarick, besides Shalltear. I want you to show me everything you know in magic "

"Lord shouldn't you talk to Lord Ainz for advice, he is a stronger caster than I or even Shalltear", Mare asked.

"That was my first thought, but he is busy with more important matters so I came to you for help and Shalltear is like a boss for me. Once I know how to fight, I'll go and challenge her to a spar. So Mare your my only choice."

"Hum....H-....okay...I'll teach you what I know, I can't promise that I'll be a good teacher for you though", Arua lifted her thumb at her brother and Filius smiled.

Later they were in the arena practicing their magic. Filius was learning a ton of spells, things like water control, fire, earth wind control too, he even learned a few summoning spells. He was currently practicing his fire manipulation when he got curious.

[I wonder is there a way I can combine my entire body with magic kind of like a buff], he then stopped his flames. "Mare is there a type of magic that gives you a fire buff?", he asked.

"Hum...no not that I know of", Mare answered, she was confused by the question.

"Ok that makes it easier", he then quickly whispered his magic, "Maximize magic Flame from hell, create, greater magic, " A fire them formed from his hand, the flame was dark purple and it seemed to burn the very life of anyone who would dare touch it. Filius then slammed his hand together forming an explosion and the flame blow up in his face.

"Lord!", both Mare and Arua yelled in worry for their master.

The fire then dimmed down and formed a silhouette, the figure then walked away from the rest of the fire, "I'm okay, I have just done something out of this world. I created my own magic" He then lifted his arms up then slammed them down extinguishing the fire out, "Hell Flame Armor"

"Incredible lord, how did you do that?", Mare asked.

"I just quickly combined various magic spells together to create a new one with creating magic", he turned around to look at the damage of his fire, there were dozens of holes in the floor around him. "I'm sorry for the mess"

"Don't worry about it Lord, Mare could always fix it", Arua said while handing her brother all the work.

"Yeah my Lord", Mare said.

"Okay so we know I can combine magic and make it simpler", he then turned around and looked at the sky, "I just accomplished something revolutionary, but I need more strength." He turned to look at Mare and Arua, "Let's keep going."

That afternoon Mare had taught Filius all the Magic she could, they didn't go too in-depth but they got the basics. Filius also managed to make new spells with his new method.

With that, they ended the day and Filius returned to his quarters, he closed his door and walked up to his mirror. "Shapeshift", his body then transformed into something else besides his metallic form, he had a human body. "This body would be good if someone wanted to see if I was really human", his father had told him that he planned to go into the human world and explore. He requested that he and Naberal Gamma joined him in this adventure so he was picking up what disguise he would use. He would also use this time to get close to Nabe and tell her about his plans.

He threw himself on his bed while looking at the ceiling, "Man what a day, I see why everyone loves this place. I swear I'll protect my home."

Timeskip...............................

The next day they all left for E-Rantel, Ainz had told Fiius that it was the capital of the region they were at. This would be the best place to make a name for yourself, it was what Filius thought.

He had decided to honor one of his uncles, the Warrior Take Mikazuchi. He already used a katana so he added some Japanese Styled leather armor and gauntlets. His pants and shoes were also in the Japanese style. Thanks to his father all his gear were maxed level so he didn't need to worry about bad equipment. He used magic to cover the areas that exposed his true body and on his face, he wore a mask of a demon made from small pieces of metal.

Ainz, Filius, and Naberal entered the city together they all walked down the main road. Filius was stoked, he saw sale stands and random people walking, he didn't like the environment though everywhere was dirt and sand. The people's clothes were ragged and old, they even were ripped, he knew that if he or his father were ruling they wouldn't live like that. He also saw adventure, but honestly, he wasn't impressed, they all were ugly looking and had the worst equipment.

Filius, Ainz, and Naberal stood in front of the INN, this would be the marking stone of the new era that would come. The mark of a new age.
