The world was once in a crisis.
There were nine kingdoms in one continent.
It was a temporary peaceful world built thanks to its perfect military balance.
But it collapsed only ten years ago.
It was around that time that an evil dragon appeared on the faraway lands of the north.
Heading towards one of the northern countries was the feared evil dragon called Colchis.
The dragon devoured people as if mowing rice, driving that kingdom to the brink of destruction.
Several countries joined forces, sending troops in order to subjugate it.
But it clear as day that the evil dragon was an invincible existence.
It’s black and shiny scales were harder than steel, to the point that it could easily repel ballista arrows and battering rams.
And then, from heights that neither swords nor spears could reach, the dragon breathed a red hot breath capable of melting steel and burned people into charcoal.
The battle resulted into a one-sided trampling which made the evil dragon angrier.
The people that it treated as food and toys tried to attack it. That fact was unforgivable.
The evil dragon immediately aimed at the kingdom’s capital, burning its castle down together with every single statesman within.
Furthermore, it spread its route towards the neighboring countries, and all the towns and villages that entered its path were also reduced to ash.
Because of this incident, the three northern countries were wiped out in a flash.
In response to this, the other six countries finally realized that a world crisis was happening.
However, there was nothing they could do.
Even with a large army, it was impossible to injure or even leave a single scratch on the evil dragon.
In that case, what could they do to subjugate the evil dragon?
Adding to that, if they fail, all the countries would be burned down out of retaliation.
If they move the armed forces, there will definitely be retaliation.
On another note, without using the army, their military strength would definitely be insufficient.
The worried countries’ leaders finally found a solution to this problem.
They selected the strongest fighting power from each country, making a team of unrelated vagrants that will attack the evil dragon.
Because there won’t be any country getting involved, there’s no need for them to worry about retaliation.
Also, because the army isn’t the one moving, it’s easy to for them to induce carelessness and they can secretly approach it.
The disadvantage of having a small number of people can also be compensated if they are fighting inside a cave that became the evil dragon’s den.
Or rather, they thought it would be better fighting it inside the cave so it can’t turn the tides by flying into the sky.
Thus, each country selected one of the six heroes.
One country, a human hero wielding a holy sword, Lyel
One country, a dwarf warrior wielding a sacred shield, Gadols
One country, an elf who mastered each and every magic, Maxwell
One country, a human saint that could heal any injury as long as you’re alive, Maria
One country, a sage of the cat people that took down a thousand lives with one command, Cortina
One country, a half-demon whose name is famed as an assassin known as Shadow Wing, Reid
In accordance to expectations, those powerful people ended this fierce battle, and the evil dragon Colchis was subjugated.
Without even losing one person, which raised unprecedented achievements— however, that was too much for their home countries to handle.
Lyel and Gadols’ fame shook the throne, Maria and Cortina popularity exceeded the Pope’s powers.
With the exception of Maxwell, who was already a prince of the Elf Country, all the five heroes positions were beyond control each country’s control.
The people of power feared retaliation from the heroes. And then there was the hero Reid…
Among the six heroes, the hero Reid was a heterogeneous existence.
He was an assassin, but he wasn’t evil.
He, who fought and killed according to his justice, was greatly feared.
The criteria of good and evil were purely based on himself, which draw a line between him and other powerful people.
Originally such reckless action would not be permitted. But his fighting strength was enough to push through it.
For this reason, as a hero—it can be said that they were selected as mankind’s trump card.
In the end, they were expelled from their home countries under the pretext of reviving the three ruined countries.
However, it was already a concluded event to them.
The Sage Cortina had already predicted that circumstances would advance in that way.
Of course, so as to not get antagonized, each country gave those rewards as means of holding down their spirits of rebellion.
The heroes knew the real intentions of those powerful people, but they went to the remote regions obediently.
That conflict was useless, they were not interested in political power and just wanted to spend the rest of their life peacefully.
But to the heroes, they knew that an end will come soon.
Everything started with the marriage of Lyel and Maria.
After getting together, the party was then disbanded.
There were no problems in their relationships, the problems came afterwards.
The superior ability they carried was too big of a power for the other adventurers to adapt.
Moreover, Gadols realized the dream of owning a store and retired.
With all main forces retired, Maxwell returned to his hometown where he could bear the title as a king.
Losing their destination, only Raid and Cortina continued being adventurers.
But eventually, there was an event where Raid had to fight against the Demon alone ending up losing his life.
The backup did not make it in time, and Cortina now all alone, also retired in despair.
Maxwell decided to settle down teaching at his newly opened magic school.
And then time passed… It was ten years since then.
