Demon Lord's Reincarnation

As Ren was facing the ORIGIN parallel to this, in the Southern borders of the Reschbeauch Kingdom King Willmont was facing his strongest foe yet. Without any hesitation, the King took out the two heirloom weapons of the royal family of Reschbeauch. 

The sword was given to his family by a hero from another world, the other worlder called it the baster sword. It was an enormous broadsword. From tip to handle, it is approximately five to six feet long, with a single-edged large blade approximately one foot wide. There were two holes near the handguard, which the other worlder said was a place to put great power into it.

Though none of the kings of the past could understand what this great power was, it didn't diminish how strong the sword was. The other worlder was the one who created the sword and called it as such. When asked why he named it so, the other world hero replied: "It was from a game I loved as a child." 

The other heirloom was a staff, that looked like a simple stick but it was anything but. This staff was created by a great alchemist from the distant past. The name of the alchemist has been lost in time. But the tale of how he handed the staff to the first king of Reschbeauch was still intact. 

The staff was worthless to anyone but the royal line of Reschbeauch since it converts there bloodline ability into mana. This allowed the Reschbeauch royalty who had almost nonexistent mana supplies to be able to use spells. 

The person in front of the king who was irritated moments ago was now looking at Willmont with renewed curiosity. As someone with a demon lineage, the man could sense the subtle changes in mana. The weapons that Willmont brought forth had interesting mana fluctuations, which rekindled the excitement the man had in facing Willmont. 

"After I kill you kingy, I think I'll take those weapons of yours as trophies." Before Willmont could respond the man moved and got behind him. Willmont was able to follow the man's movement and blocked with the baster sword. A dull clang could be heard as the sword and nails clashed. 

Willmont then raised the staff high into the air and summoned lightning that came down from above. The man was able to evade the lightning strike, but this time Willmont was able to get behind him and struck with the baster sword. 

The man then quickly evaded the strike by jumping forward and rolling on the ground. Willmont didn't allow the man to have any breathing space as he quickly followed through his assault. After a few more clashes Willmont had the man cornered, it was then something different happened. 

The man took off one of the rings on his fingers. Willmont didn't understand what that was for, but this gave him the perfect opportunity to get a strike in. Yet as he slashed down at the man, Willmont's blade was stopped. 

Willmont seeing something was happening quickly backed away and saw what had stopped his blade strike. The man who looked like a normal human being had now two blade-like bones extending out of his wrists. That wasn't the only difference the man's body had, now there were two bone-like things coming out of his back that were shaped like spider legs. 

"You're pretty good Kingy, you actually forced me to show you a bit of my true form. That man called the Grand Mage or whatever was too prideful and full of openings. Well, he was also too old to be able to play around with me. You on the other hand, with those weapons at hand, are awesome. Out of respect to your skills human, I will grant you the honor of hearing my name. I'm the descendent of the demon General Namor, the second in command of the great demon lord's armies, my name is Amon." 

After announcing his name in a grand fashion, Amon started walking towards Willmont. Even as the enemy approached Willmont remained steady and didn't move an inch. When Amon got near enough to Willmont that extending his arms he would be able to touch the king, he spoke. 

"Let's start this in a more proper way, shall we. I Amon descendant of General Namor stand before you ready for battle. Now human king state your name."

Even though Willmont couldn't keep up with the changes in personality Amon was going through, he still responded in kind. 

"I King Willmont Reschbeauch stand before you ready for battle." He didn't know if those were the correct words in response, but Willmont saw Amon smile a bit. After the two gave their names, the battle restarted. 

In his new form, Willmont was having difficulty blocking Amon's attacks. The attacks came from all directions, using his new limbs as blades that could attack in any direction made fighting Amon difficult for the Willmont.  

After a few exchanges, Willmont knew that he was no match for Amon. Once he came to that conclusion Willmont decided to risk it all in one attack containing all the power he had. Sensing the change in Willmont, Amon backed away and smiled as he started gathering mana into a single point of his blade-like limbs. 

Willmont raised his sword above his head and waited for Amon to charge at him. As if able to read Willmont's mind Amon accepted the challenge and charged forward. Seeing the demon in front of him adhere to warrior etiquette made Willmont smile as he unleashed the strongest and fastest attack he could muster at the moment. 

The charging Amon passed by Willmont and the two stood completely still for a few seconds. 

"Heh, you really were pretty good for a human." One of Amon's spider-like limbs were cut off and a part of his neck was bleeding.  

"It was an honor to have faced an opponent such as you." The king smiled for one last time before revealing that his body had been cleanly cut vertically. Amon looked at the fleeing soldiers at the distance and turned around as he picked up Willmont's sword and staff.. Once he got the weapons and picked up the five loyal retainers of Willmont, Amon left without chasing any of the fleeing soldiers.
