Demon Lord's Reincarnation

Kim Chul was what you would call your average everyday teenager. He would go to school, he would leave school with his friends to go and hang out. He would return home pretend to study, but in truth was just playing video games, or sometimes watch some vtubers. 

His everyday life was the same thing over and over again. There was no particular thing of interest. 

...

One day as he was playing on his laptop he noticed something weird. A questionnaire suddenly popped out, usually, he would quickly dismiss this thing, but for some reason, he felt drawn to it. Also, the topic was something he quite liked. 

If you were transported to another world, what class would you pick? It was just like a character creation screen. After answering a few basic questions like name and gender, Kim Chul arrived at the part which was like class selection. 

Do you wish to be a swift and silent Assassin? This class uses daggers, whips, and bows. A class suited for those who wish to finish off their opponents without being seen. Assassin is a class suited for the shadows, their speed and stealth are unmatched. 

Do you wish to be the raging Berserker? This class uses all two-handed weapons, from swords to staves. A class that doesn't know the meaning of defense. Berserkers are fearless warriors of the battlefield and only death could stop them. 

Do you wish to be the elegant Sword Dancer? This class uses every type of sword imaginable. A class that dances around the battlefield like a deadly fairy. The beauty and elegance of each strike are equally deadly and proud. The Sword Dancer is a class suited mostly for one on one battle.

Do you wish to be the powerful Mage? This class uses offensive magic. A class that uses the elements of the world to do his bidding. The Mage Class offers large scale attacks the decimate the battlefield. 

Do you wish to be the faithful Paladin? This class is defense-oriented and offers various buffs on one's self. A class that uses a towering shield coupled with one-handed weapons. The Paladin class boasts an unrivaled defense.

Do you wish to be the jack of all trades master of none, Mage Knight? This class is an all-rounder that could use weapons and magic. A Mage Knight is much sturdier than a mage and has more powerful area damage than a Sword Dancer. 

'They're all somehow offensive type classes with the exception of the paladin. There's no real support type class, well the Paladin and Mage Knight were kinda like that. I wonder what I should pick?'

Kim Chul looked at the classes again, even though he knew that this was a simple questionnaire and not an actual game, he still wanted to choose seriously. 

'Even though it doesn't say it, each class has distinct weaknesses. The assassin class has the obvious weakness of defense, and most probably power since it does say speed and stealth. The Blade Dancer is a duel type class, basically a PVP class. The Berserker sounds nice, but the no defense does sound a bit scary. The Mage is most probably similar to the other mages in most MMOs, it should basically be a glass cannon. The Paladin and the Mage Knight seem to be the most balanced. The Paladin focusing more on defense with little offensive abilities, while the Mage Knight should be versatile but with no absurdly powerful abilities. I wonder what should I pick?'

...

After that event, Kim Chul was transported to another world were he was given the task to be the hero of the Holy Kingdom. It has been five months since he had come to this other world and all he did was try to level up. His current stats were high as unlike the people in this world who need to train their whole lives to grow stronger, all Kim Chul needed to do was kill, gain experience, level up, and he would grow stronger. 

This world truly felt like a video game to him, if not for the pain he felt he would've thought that he was in a dream of sorts. He had already defeated a lot of monsters, and even a boss monster called a Primordial Demon. 

The Primordial Demon that attacked the Holy Kingdom a few weeks ago, was so strong he thought that he would die then and there. After he gained the victory, Kim Chul knew that he was too overconfident recently. So without any delay, Kim Chul started looking for stronger monsters to kill to level up faster. 

He now had defeated many beings, from trolls to King Drakes. Kim Chul's current level was far beyond what it was when he fought the Primordial Demon. His stats were now like this:

HP: 42,000/42,000 MP: 2,350/2,350

STR: 18,000

AGI: 20,400

DEX: 20,400

INT: 1,530

WIS: 1,000

VIT: 7,322

Luck: 1000

Compared to the Sword Saints of this world, which the Holy Kingdom has two, his stats overshadow them. To have a clear picture this is what a normal Sword Saint stats look like:

HP: 18,000/18,000 MP: 950/950

STR: 4,200

AGI: 8,400

DEX: 8,400

INT: 430

WIS: 500

VIT: 1,300

Luck: 40

He was so much stronger than those this world consider to be near the top humans. Yet today he was facing three very special people. 

...

When one of the priests of the Temple of the Goddess of Light told him there was a disturbance in the food district, and he had to go help, Kim Chul was confused. Usually, as the summoned hero he would be given missions like killing a troll attacking a village, or a mission to protect the Holy Kingdom like the time with the Primordial Demon. In the several months, he has been in this world, he never needed to deal with some public dispute, that was usually the job given to the guards. 

Still, since the monsters in the surrounding area were no longer giving any EXP, he had nothing to do so he decided to look at the disturbance. Based on the initial report there were four criminals who suddenly attacked some citizens and fought the guards and even some knights. 

These four were suspected to be a part of the rebel army called the Fangs of Katar. Kim Chul had heard about this rebel group that has caused numerous disturbances in the Holy Kingdom. Supposedly this rebel group was composed of demi-humans that wanted to destroy the Holy Kingdom as an offering to their evil god. 

Kim Chul wasn't that interested in the politics of this world as he was currently focused on leveling up. He just wanted to get as strong as possible, so that he could protect himself. Since it was obvious to him that he was summoned here to fight some great evil. 

Still, no matter how many times he asked the head priest about his actual task, all the head priest ever answered him was that he wasn't strong enough to know yet. The head priest did tell him to simply focus on leveling up for now. The head priest and the reason he was summoned into this world was obviously suspicious but Kim Chul who was treating this world as a video game decided that the main quest wasn't available to him since his level was too low. In fact, that was the only way he could still remain somehow sane after all the things he has been through.

'I wonder what kind of opponents I'm about to face that they actually needed to send me. Well, it doesn't matter if they're just some slightly stronger Swords Saints then I can deal with four no problem.'

That's what Kim Chul thought as he headed to the scene of the crime. 

...

Upon arriving at the scene Kim Chul quickly spotted the four criminals. The guy who was torturing the person on the floor was obviously one of them. The lady who was fighting the wyvern knights was another. The guy who was carrying two beastkin children watching the fight with a smile on his face, and the one standing behind him, that was all four of them. 

After spotting the four, Kim Chul walked in between the lady and the knights. Seeing that Kim Chul had arrived the Knights backed off and so did the lady.

'Alright let's just get this over with.'

"I heard you people are causing a lot of problems." Once Kim Chul said those words he suddenly felt a chill down his spine. He then heard someone speak to him, it was the man who was carrying the two beastkin children. The man had handed over the children to the one behind him and spoke. 

"To what do we owe the pleasure, hero!" The smile on his face was like that of a lion, ferocious. 

"Hmm..." Kim Chul didn't reply as he felt something bad was about to happen. So he used one of his initial skills, which was the status check. He tried to look at the man's status and was surprised at what he saw. 

Name: Ren

Class:???

Secret Class:???

HP: ??? MP:???

STR: ???

AGI: ???

DEX: ???

INT: ???

WIS: ???

VIT: ???

Luck: ???

Kim Chul couldn't believe his eyes everything aside from the name was ???. 'What the f*ck did my system bug out?' Kim Chul then checked the status of the others. First, he looked at the man standing behind Ren.

Name: Johnathan Brown

Class: Guide

HP: 120/120 MP:10/10

STR: 15

AGI: 20

DEX: 20

INT: 18

WIS: 19

VIT: 12

Luck: 10

When Kim Chul saw that he was relieved as that was the normal standard of the people of this world. He then looked at the man who was torturing someone and was once again surprised. 

Name: Valdel

Class: Hero

Secret Class: Former Demon Lord (Past Life)

HP: 32,000/32,000 MP: 12,350/12,350

STR: 24,000

AGI: 28,400

DEX: 28,400

INT: 950

WIS: 820

VIT: 10,322

Luck: 10,000

Except for HP, INT, and WIS that person was stronger than him. That guy was also a hero like him, and he even had a secret class called Former Demon Lord (Past Life). Kim Chul then quickly checked the last member which was the girl.

Name: Lara

Class: Fighter

Secret Class: The Seeker 

HP: 22,000/22,000 MP: 1,350/1,350

STR: 16,000

AGI: 19,700

DEX: 19,700

INT: 970

WIS: 820

VIT: 5,322

Luck: 400

Even though she was weaker than him it was only a small number difference. The three in front of him were the strongest humans he has ever seen. Still, he was confused as to why Ren's status was filled with ???. 

'Does that mean I can't see through it, since the level difference is too large?' Even the Primordial Demon from before was stronger than Kim Chul by a large margin, but even then he could still perceive his status. Then how much stronger does Ren need to be for him to show ???. 

Kim Chul was feeling afraid. Even though he already knew that the one with the higher stats wouldn't necessarily win as evidence by his fight against the Primordial Demon, but even then... If it was only Valdel and Lara, he could still deal with them if he used his ultimate skill. Yet he wasn't sure if he could deal with Ren even if he used all of his trump cards. As Kim Chul was thinking about what he should do next, he heard Ren speak to him. 

"Oh, so you're one of those types. You're a summoned hero with the ability to strengthen himself by killing. Just now you checked on our statuses, right? What did you see, oh hero?" When Kim Chul heard what Ren said he was stunned. 

Even the people who summoned him didn't know that he had the ability to see statuses as he kept that a secret, yet Ren knew. Those eyes looking at him, felt like they could see right through everything. 

"Just who are you?"
