Can humans and dragons coexist?
A mystical continent where humans and dragons have existed together since ancient times. This continent, which had maintained peace for centuries based on the logic that the two races could coexist, now sees the sparks of war ignite due to the dragons' desire for dominance.
Dragonic Blood, a dragon alliance including four of the Six Great Dragons. And the Dragnia Allied Forces, a coalition of humans and moderate dragons opposing them. A war written in the blood of humans and dragons: The Dragon-Blood War.
Who will ultimately emerge as the victor?


An army of dragons gathered to subjugate humanity.
An alliance of dragons who harbor grudges against humans for their own reasons, or who view humans purely as prey.
It is an unprecedented dragon coalition featuring four of the 'Six Great Dragons,' the most powerful beings on the Arcadian continent. Due to their overwhelming strength and ferocity, countless humans are currently suffering.

An allied force gathered to protect the bond between humans and dragons.
The Dragnia Allied Forces were formed to protect the solidarity of humans and dragons from the tyranny of Dragonic Blood.
Composed primarily of moderate dragons and humans, they stand in opposition to Dragonic Blood. The army is led by Queen Serena of Dragnia as the head of the alliance, Katrina, the second princess of Eisenroth, as the Commander-in-Chief, and Miriel, the court mage of the Astrabeil Magic State, as the strategist.
"Humans and dragons can coexist. Just like the peace of the Kingdom of Dragnia that has lasted for centuries."
「The Dragon Queen」 Serena Dragnia
Serena is a 26-year-old woman who believes in peace between dragons and humans, serving as the 20th Queen of the Kingdom of Dragnia.
She believes that humans and dragons can live together in harmony and formed the Dragnia Allied Forces to protect humans from radical dragons and maintain the bond between the two races.
"I was once a princess of Eisenroth, but now I am the commander of the Dragnia Allied Forces. I will lay down my life for Her Majesty."
「Commander-in-Chief of the Dragnia Allied Forces」 Katrina Eisenroth
Katrina is the second princess of the neighboring Eisenroth Holy Kingdom. Having been pushed aside in early power struggles, she walked the path of chivalry from a young age to protect the royal family.
Now, she has joined the alliance to protect human peace from the dragons. As a loyal knight protecting Serena, she takes to the battlefield wielding 'Ascalon,' the holy dragon-slaying sword passed down through her royal line.
"Those dragons, they certainly know how to cause a nuisance."
「Strategist of the Dragnia Allied Forces」 Miriel Astrum
Miriel is a 47-year-old woman and the court mage of the neighboring Astrabeil Magic State. She is a middle-aged mage who has fixed her appearance in her 20s through magic.
However, her skills are undeniable, and she currently plays a vital role in the war as the strategist for the Dragnia Alliance.
"Humans are not prey for dragons, but beings with whom we must join forces to draw the future."
「Guardian Dragon of Dragnia」 Lucinir the Radiant Dragon
Lucinir is the guardian dragon who has protected the Kingdom of Dragnia for generations and is the Radiant Dragon representing light among the Six Great Dragons. She is willing to give her life to protect Serena and Dragnia, serving as the spiritual pillar and core military strength of the Allied Forces against Dragonic Blood.
While she possesses power near the top even among the six great dragons, her gentle nature means she does not enjoy fighting.
"Coexist with humans? Do you intend to throw away the pride of dragons? Humans are all just food. There is no predator in this world that coexists with its prey."
「Leader of Dragonic Blood」 Caligonus the Abyssal Dragon
Caligonus is a dragon of darkness notorious for having the most ferocious personality among the Six Great Dragons. She formed the blood alliance known as Dragonic Blood with the ambition to subjugate humans under her and eventually bring the entire continent under her rule.
"I just want to eat. I don't really care about the fighting~"
「Breath of Decay」 Lindwurm the Venomous Serpent Dragon
Lindwurm is one of the six great dragons who commands poison, a powerful predator that corrodes everything with deadly toxins and swallows them whole. She joined Dragonic Blood after yielding to Caligonus's power and enters the war to devour even more humans.
"Why did I join Dragonic Blood? That's obvious—because I want to fight!"
「Iron-Blooded War-Maniac」 Volcania the Purgatory Dragon
Volcania is a battle-maniac who pursues pure combat. She joined Dragonic Blood simply out of a desire to fight strong opponents. In this war, she doesn't care who wins or loses; she only wants a battle where she can clash with everything she has.
"It is because of you humans that my sea is in turmoil. I intend to collect that debt."
「Ruler of the Azure Sea」 Mareciel the Sea Emperor Dragon
Mareciel is the dragon king of the sea who rules the azure waters. Among the six great dragons, she was originally a queen of a maritime kingdom where humans and dragons coexisted, possessing a gentle nature rivaling Lucinir's. However, unable to stand by as the sea became polluted and the marine ecosystem was destroyed by human greed, she joined Dragonic Blood and turned her back on humanity.

The Arcadian continent.
It was a world where humans and dragons existed. Because both lifeforms possessed high intelligence among the creatures living in the world, they naturally became the pillars of the world.
Humans banded together to form civilizations, and dragons learned the ways of cooperation by living alongside those humans.
Among them, the Kingdom of Dragnia was a nation established by the combined efforts of dragons and humans, playing a significant role in showing the entire continent that the two races could coexist.
Because Lucinir, one of the six especially powerful dragons known as the Six Great Dragons, wisely coordinated the relationship between humans and dragons alongside the Queen of Dragnia, they became a model for neighboring nations.
Hmph, ridiculous. Coexistence between humans and dragons? What nonsense. To a dragon, a human is nothing but prey. How arrogant of them to try and be treated as equals.
However, not all dragons agreed with those values. Caligonus the Abyssal Dragon, also one of the Six Great Dragons and the polar opposite of Lucinir, was one such dissenter.
She formed 'Dragonic Blood,' a dragon alliance with the intent to subjugate surrounding dragons through force and place all humans beneath her feet.
This news spread across the entire continent.
Instances of human kingdoms being attacked by dragons increased, and eventually, some neighboring nations began to define dragons as the enemies of humanity.
