One day, two identical children were born to a farming family on the border of Caslano, whose parents named them "Green" and "Geert".

Although the brothers look like each other, their personalities are diametrically opposed.

The elder brother Green has a cowardly temperament, and the younger brother Geert has a strong personality and arrogant ego, and the first reaction when encountering an obstacle is to think about breaking it.

When the two were fourteen years old, they were tested by missionaries passing through a small border town to control spiritual power, and they were given the title of "Capable Ones", and they were also the first pair of capable people to appear in the place where they were born.

The missionaries had no time to teach them the magic of performing miracles, and after their family and most of the townspeople had converted to their faith, they made an excuse to hurry on their way.

The two brothers, who lost their teacher, could only resist the ardent hopes of their neighbors and explore ways to refine and control the spiritual power of the atmosphere by themselves.

They train on time and every day to help their parents and those around them who need help, and it seems that the flames of war will never reach the surrounding city, and they will always be able to live in peace and tranquility like this.

The two of them thought they had never done anything unethical, and they didn't even deliberately do or say anything about the Kaslano's consistent discrimination against their neighbors...... But no one could have imagined that he/his relatives and friends would be in great trouble when he was 20 years old.

The civil strife in neighboring Adriel has caused many nobles who have relatives in Caslano to flee here, including a mad historian who has mastered the principles of the "guardian beast" contract.

The loss of her husband and children in the chaos of Adriel, and the separation of all her husband's relatives from her, drove her into a frenzy, ostensibly a helpless, mentally fragile woman, but in reality held over a secret that could destroy a nation, waiting for someone to pry her mouth or heart open.

The ruler of Caslano, "Yoi", did just that.

They are plotting to take advantage of the illness in the neighboring country to directly overthrow the rule of the old king, set up a puppet regime, and then encroach on Adriel's territory little by little.

In addition, the eyes of humans have also turned to the "Beast Island", which is related to the secrets of the "Guardian Beast", which is a hermitage for the beasts, and in addition to the ancient life forms that may have existed since the birth of the planet, new life is constantly being born inside.

The newly-born beasts are unwary of the creatures of the outside world, and humans lure them out with "contracts", and then invest them in various projects, squeezing all the value that can be used from them.

Due to the large number of orcs sent into the land of Kasrano, the "human supremacy" church has been given room for development, the monster hunters have been given employment opportunities, and the contradictions between human countries have been buffered, gradually turning into conflicts between different races.

With the addition of the new variable "Third Orc", Kasrano, known for his orc hybrids, and Adriel, who gained power from the "Mark of the Guardian Beast", finally have a common threat.

In the face of racial interests and survival, the original justification for war was a joke.

However, this is limited to the surface.

Because this "third party" is a conspiracy devised by the emperor of Caslano and a down-and-out nobleman who has a secret, the orcs were brought to the territory of the human race by themselves, and only the upper echelons of Adriel and his people, as well as the lower people of Casrano, were deceived.

Even if the neighboring countries have solved the internal and external troubles of the time, the new king will inevitably be dragged into this grand conspiracy, and they will have more opportunities for development, and the gap between the two countries is bound to grow in the next few years.

However, the empire designed its neighbors, but it also harmed its people.

The catastrophe of the Grimm and Gelt brothers came from the orcs who were sent into the land in this scheme.

In those beasts, there are intractable and deadly infectious diseases against humans, and the "causes" of biological diseases are varied, and experts and scholars laugh at them.

The "cause" here is not a "reason" such as being injured, catching a cold, swimming in a river, or approaching a resentful spirit, as is the case with traditional diseases, but rather a "logic" or a "law".

It's like an ordinary person being cursed inexplicably, and when he inquired, he found out that he accidentally yawned last year, and as a result, the breath he exhaled stinked and killed a passing bug, and that bug happened to have a dose of medicinal materials needed by the spellcaster, so the spellcaster wanted to curse him to death.

But this is the "law" of the "beast disease" that humans suffers from, and this absurd law is reflected in the characteristics that patients share.

Sometimes it's something they do habitually before they get sick, and people who have this habit get sick; Sometimes it's because of their bloodline, and people whose ancestors are from a particular beast clan get sick; There are even times when they have a common mantra and people who say it often get sick; Or after a certain number of people who are related by blood have died, even if they do not die from the disease, the rest of the family will become susceptible.

There are also diseases that can only be transmitted to people "other than blood relatives".

If one of the unfortunate people in a family wins, the rest can applaud and cheer, while their neighbors are all in danger.

And these infectious diseases brought to humans by orcs for different reasons have one and only thing in common: that is, a part of their body suddenly loses its color and fades to pure white.

Pure white, the color of death.

Whether it is a small patch of skin, a fingernail, an arm or leg, or a handful of hair, as long as there is a "discoloration" on the body, that person will become the object of fear and hatred, and that person will no longer be a "person".

A tuft of hair on Green's forehead, turned white.

In his short black hair, it stands out.

And he had the disease that "only blood relatives can be infected", so his parents and brothers can be kept safe as long as they hide in the house.

None of the people who had been dreaming of becoming capable would want to die in vain because of contact with Green, and their parents and other relatives also had different concerns, believing that the sick person should cut himself off from future troubles, and if he didn't have the guts, he shouldn't stay in this small town, because they didn't want to have their hands stained with the blood of the same kind, and they didn't want to be implicated by the patients.

The only person who hasn't changed his attitude towards Green is his twin brother, Gelt.

Geert's personality determines that he is more likely to encounter opportunities than Green, so he knows more about "spiritual power" than Green, and will perform more kinds of miracles.

He summoned pure atmospheric spiritual power to protect himself from fatal diseases, and with the two conditions of "blood connection between himself and his brother" and "brother Green has talent", he designed a simple spell formation to save his brother's life.

"Next, we just have to wait for the scholars to come up with countermeasures to fight the disease."

Geert took his brother away from the chilling border town, and in order to comfort his frustrated brother, he miraculously dyed his hair white with the materials he had obtained on the way, and kept a tuft of black forehead hair to match his brother.

"Look, we're all the same now, brother." He said so.

"Don't be sad about the things in your hometown, brother, it's the ungifted people who are jealous of the gifted us, when they still need us before, they don't need to show this nature, and once they get a reason, they will not hesitate to hurt us, as a way to show that they can overcome us as incompetent people."

The two embark on a journey where they can only depend on each other.

Years later, in a distant city, they passed by a church decorated with a swastika and recalled the words of the missionaries.

At that time, the era of infectious diseases was a thing of the past - it is said that the emperor and his minions flipped through a history book called "Another Time and Space: The Other Era", and found a solution to the problem in it, saving the lives of most of the people in time.

However, the grievances and sufferings they suffered will not come to naught with the end of the incident.

The two men immediately joined the church and began to avenge their past misfortunes.

They received the approval of the bishop known as "Mr. Whitebridge" and were invited by him to join the Church's team called the "Seven Virtues."

The timid and fearful Green became "temperance", and the arrogant and troublesome Geert received the name of "humility".

They have access to the information about the beasts collected from all over the world since the establishment of the church, and they are required to fulfill the obligation to seal the beasts and kill the beasts.

While they shoulder more responsibilities, they also get the opportunity to find the real object of revenge, and even if they can't find the culprit of the disease, they can solve the orcs they encounter one by one, and kill them to the end, maybe the other party will come out on their own.

……

"Mr. Shirabashi is a little weird today, brother."

"Hmmm......"

"He listened to what Gai reported and his face became very exciting, and I was standing on the sidelines, and I wanted to applaud his performance, brother."

"Hmm...... Gelt, Mr. Hakuhashi is wearing a mask, and you can't see his expression. ”

"Don't underestimate my eyes, brother, let's not talk about this yet, but he immediately sent us out to 'welcome' the return of a certain beast? Holy Cross, O Alternate Time and Space, what does he think? What do you think, brother? ”

"He's probably too tired."

"You have a point, and I think so, so we don't have to take the order literally, all words have their implications, don't we, brother?"

"Hmmm......"

"And, based on our investigations over the years, that disease is more like a 'curse' from some beast king, and it curses us humans! Well, it will have to pay a terrible price many years later! Isn't it, brother? ”

"Hmm...... You're right, Geert. Green's tone suddenly became firm.

"Let's go 'meet' it, then, brother." Geert looked up at the dilapidated mansion in front of him, and felt uncomfortable with the plants that grew on its building materials.

But what made him even more uncomfortable was the existence of a creature in it.

The two approached the mansion, and before they could pass through the main entrance, they saw the beautiful orcs standing indoors, enough to catch the eyes of all who witnessed them.

It radiates a holy radiance, white as if it were made of ice and snow, and its two large horns are like the finest works of art, shining in the light of the beams of light that pass through the roof and into the room.

"You're finally back." Geert mimicked the sarcastic tone of their "Mr. White Bridge" when talking about the beast, and turned it into the other's rhetoric.

"Write a false evil beast that has been expelled from the position of a divine beast, hideous."

Of course, neither of them noticed that the little beast sitting on the back of the ice crystal giant deer was the real goal of their trip.
