The Isekai Adventure System
The hero!

Sveinar had been brainwashed into evil with his blank gaze that was guarding the body of the dying demon lord.

Sven is forced to cripple his sister to finish off the demon king, now Sven and Sveinar are facing off and will start their battle.

Sven tried not to hurt his sister who only used his physical strength, but every attack was always imitated by Sveinar.

Sven learns that his sister has the ability of Copy Skills that can imitate any movements and moves he sees, therefore Sven will not use other skills such as Time Stop or Disable Power, because if his skill was imitated by his, then Sven would have trouble fighting him.

For now Sven only used his physical strength and only used his teleportation skill.

Every move and attack that Sven did would instantly imitate him and make it difficult for Sven to find a way to defeat his sister.

Fortunately Sveinar who is now still C+ rank and can still be made Sven retreat little by little.

Although Sveinar has the status of C+ but he can rival and match the physical strength of Sven who is already OG status!

Sven thought if his sister had reached SSS+ rank maybe he would be equivalent to his sister.

The stupid demon king who brainwashed Sveinar while C+ rank and did not brainwash Sveinar when he was SSS+ status.

Sven would not let his sister be brainwashed a second time by the next demon lord and would end this now before it was too late.

When Sven and Sveinar were fighting each other and fighting an attack, Sven was thinking hard to find a way to defeat his sister.

For hours they fought each other relentless physical attacks and made Sven have no other way but to use his other skills.

The demon lord was about to recover and was about to escape again, yet it took a while longer to fully recover the demon lord's wounds.

Before that happens, Sven must defeat his sister to stop the demon lord from escaping.

First of all Sven will use his Time Stop skill and will instantly paralyze his sister by hitting the back of her neck when time is stopped temporarily.

His first plan was successful and he immediately launched his second plan, which was to use the Disable Power skill on his sister, which made him unable to use any skill for a while, then Sven would bind his sister's entire body and would close his sister's eyes.

Now Sveinar has been collected for a while, and Sven manages to defeat his younger brother.

Now it was time for Sven to kill the mortally wounded demon lord Luc-III.

As usual, Sven used the Disable Power and Time Stop skill on the demon lord to guard against his cunning tricks.

After that Sven immediately executed the demon lord with great brutality and torment when time was stopped.

Sven chopped her up using Lion-O's sword, skinned her, mutilated her, and had her chopped off her head.

The demon king's body was already separated and had been cut into small pieces, then Sven put all the pieces of the demon king's body that had been cut into pieces into his magic bag.

Sven then brought the fainted Sveinar to the Sky Kingdom to be healed by the God Diyn.

While Sveinar was being treated with the Diyn God skill with the heaven light, suddenly something came out from inside his mouth.

Out came the pulsating black flesh from Sveinar's fainted mouth.

The mother and father who saw it immediately cried and grieved, because the small and innocent Sveinar was a victim of the behavior of the demon king.

A few days later Sven had already summoned all the members of The OFS back to the Sky Kingdom to recount his incident against the demon lord a few days ago.

Now Sveinar has realized from the stupor and has returned to normal as usual.

Sveinar does not remember anything when asked about the events that happened to him some time ago , Sven also told the incident to Sveinar from beginning to end.

.

Then Sven took out the head of the demon king Luc-III from inside his magic bag as proof that he had managed to kill the demon king.

Everyone who looked to the demon lord was instantly shocked and startled because sven had actually killed him.

The news of the demon lord's slaying had spread to all corners of the world that was spread directly by the gods and some adventurers who saw him head-on.

Sven was then forced to take the demon king's body to a place that looked like a sacred place surrounded by strange objects.

The place was attended and witnessed directly by the kings of every kingdom and also the gods.

Sven had already placed all the pieces of the demon lord's dismembered body into the magic circle of the gods to eliminate and scorch the demon lord's body forever.

The ritual lasted for hours and had transformed every part of the demon king's body into a golden bead of light that entered Sven's body.

Suddenly a notification popped up from her status screen.

Then after the ritual was completed, now Sven had become an adventurer who managed to become the second Hero officially.

Sven was given the Hero sign on the collar of his clothes like a small iron and gold star-shaped.

The mark had been worn by a Hero before who had been killed by a demon lord.

Now Sven is a Hero who is recognized by all the kings who are watching it.

The kings who witnessed it will tell all the citizens of their respective kingdoms that a Hero has appeared and reappeared after hundreds of years have passed.

Sven became very famous and had already surrounded all the kingdoms to visit every adventurer guild in the various other kingdoms.

Because it's a newly raised Hero tradition.

Although Sven was embarrassed and did not want to show the status of his Hero to everyone, but he was forced to do that to respect the traditions of the kings.
