Demon Lord's Reincarnation

Ren became excited as he heard the news of seven heroes appearing in the allied kingdoms' ranks. Each one of these so called heroes were extremely powerful and with distinct styles of combat. The knights who had survived the encounter with the seven reported back to Ren. 

There was a gigantic man who held a halberd of equal size. He was the most aggressive of the heroes it was as if he did not fear death, in fact, it was like he was seeking it. The way he deals with his opponents is pretty straightforward charge at everyone and slash away. He doesn't defend nor does he dodge any attacks, but no matter how much he gets hit he doesn't stop and only grows stronger. 

That was the type of hero Ren liked fighting the most since both of them could simply duke it out. No need for fancy techniques just a brutal pounding. 

...

Then there was the supposed gentleman of the battlefield, to this date this person has not killed a single knight. He was courteous to everyone even to his enemies, but even then he wouldn't allow anyone to pass through the border he was protecting. 

This person's way of fighting was the exact opposite of the gigantic man and used softer tactics. If it wasn't for Ren training his men to never retreat, they wouldn't have gotten beaten up so much. 

...

There was also the woman described to be incredibly beautiful and haughty, her beauty could rival Tsukiyomi and the rest. She had the demeanor of a king and every time she meets any knights she would offer them any price they want if they would follow her. If they refuse she would use some mysterious techniques and would decimate any knight squadron without even standing up from her golden throne. 

That golden throne that she sits upon is able to move from place to place by floating, the knights that reported to Ren had already confirmed that she didn't use any mana to move the throne and sometimes she would talk to it, it was as if it had a mind of its own.

...

There was also an unknown hero that doesn't show his/her face as she would easily kill those that come close to his/her territory. 

...

Another hero was the man who always sleeps like Nezzard, but unlike Nezzard this man never leaves his bed and like the golden throne the bed moves from place to place. This man's ability was weird as he would do some hand gestures and manipulate his opponents' movements without using any mana. 

...

Then there was the strongest of the summoned heroes, the little girl who warns any of those that come close to her space, that they would die. The knights who watched as their comrades continue onward and simply die without any explanation were confused. They had tried numerous times to figure out what kind of power the little girl had but no matter how hard they observed they could not understand how she killed her opponents. 

Unlike the man on the bed who also used a weird power or the lady on the throne, who both make hand gestures as they attacked or at least move some body part to indicate they had attacked, this little girl was always meditating even as she kills. After giving out her warning she would not even open her eyes, which makes the way she kills the most horrifying. 

Also unlike all the other heroes who at least dodge when being bombarded by spells, this little girl could reflect any spell base attack without moving an inch. Among the heroes present, she was the most frightening.

...

Then finally there was the weakest of the heroes, yet has the greatest potential to advance. In the beginning, this hero was extremely weak and could not even defeat the weakest of knights, but his escaping skills were excellent, helping him survive the battlefield. 

Yet as time went by this particular hero was getting stronger, and it was not just little growth spurts. Every time he would appear his strength, speed, technique, everything about him would improve drastically. 

Nowadays he could easily defeat a squadron of knights, without sustaining so much as a scratch. He was even wearing better equipment compared to when he started. 

...

When Ren heard the description of the last hero he was reminded of someone. Wasn't there a hero in his past life who continued to defeat monster after monster and every time he battles he would grow stronger and gain new skills? 

'Is it possible that someone similar to Sora appeared?' 

Simply thinking about his fight with the first hero he encountered made Ren's blood boil in excitement. He could no longer hold it in and wanted to see these so-called heroes for himself. He immediately headed for the base of the allied kingdoms. 

...

Upon arriving near the allied kingdoms' base Ren used one of Shadow Clan's techniques that he had improved and blended into the environment so no one could see him. He walked through the base and saw the other heroes. 

When he saw each one he felt a tiny bit disappointed, he could tell their level at a glance. In his current state, none of them were his opponents. Still, they could probably fight on equal terms with the current Tsukiyomi, Lara, and Silika who were not in their peak states. He then decided to let the three of them deal with these heroes.

He also found he hero who had a similar ability to Sora and to his surprise this person looked very similar to Sora himself, in fact, if not for some differences here and there, Ren would've thought that Sora had revived. Ren then came to the conclusion that it was possible that this was a descendant of Sora's.

Unlike the other heroes Ren saw, he knew that this person still had room to grow stronger and at a quicker pace than the others. For now, Ren would wait until this person reaches his maximum level to see if he could face him. 

Since he already saw the descendant of Sora, Ren was about to leave when he suddenly felt a powerful presence that was near his own level close to him. Ren smiled as he turned around and saw a little girl staring straight at him. At first, the little girl looked like she wanted to attack, but suddenly she had this look of extreme horror fill her face, and after trembling for a bit she fainted. 

'... Did this girl try to peek into my soul?... How unfortunate, I thought she would be a good playmate, but I guess after seeing what's hidden within she won't even have the guts to lift her head in my presence. How disappointing, I guess Sora's descendant is the only hope I have for a good time.' 

Ren who had infiltrated the allied kingdoms' base with high spirits left dejectedly.
