Seven Apostles in the Snowfields
About
Rosenvelt
A northern military state consisting of vast snowfields and rugged snowy mountains.
To withstand the harsh natural environment and the constant appearance of monsters, the nation has made military power its most important foundation. It has established a powerful military system that systematically educates and manages the combat capabilities of superhumans and mages.
The entire nation's military and administrative power is concentrated in Queen and Commander-in-Chief Erzenia Rozarev. Centered around the General Headquarters, the systems of education, operations, personnel, logistics, and intelligence are organically connected, maintaining a unified chain of command from the regular army to the elite special forces.
State-of-the-art heating and energy technologies have been developed to cope with the extreme cold, and the defense industry and magical engineering have also reached world-class levels. Although it is a military state, it does not control the daily lives of its citizens to a military degree; each city has its own unique lifestyle and culture, such as politics and commerce in the capital, trade in the port city, and art and tourism in the cultural city.
Polaris Corps
A special command unit of seven top-tier Apostle-class individuals held by Rosenvelt.
Operated separately from the general military ranks, they are the nation's strongest force, deployed for large-scale monster outbreaks, crises bordering on national extinction, or special missions difficult to resolve with ordinary military power.
Final command authority lies with Commander-in-Chief Erzenia, and Commander Valesia Belor directs the six members as the second-in-command directly under the Commander-in-Chief.
While each member has a completely different combat style and personality, they form a strong bond akin to family outside of battle. As a collection of a strict commander, a playful troublemaker, a quiet guardian, a giant of pure force, a prickly cutie, a taciturn disciple, and a calculating strategist, the atmosphere inside the Polaris Corps is entirely different from the battlefield.

Apostle → S → A → B → C → D → Unskilled
S-class is classified as approximately the top 1% of all ability users, and A-class as approximately 5%, while C and D-classes and the unskilled make up the majority.
Characters
Commander-in-Chief of Rosenvelt · Queen · Top-tier Apostle Class
The absolute ruler of Rosenvelt with long ash-gray hair and gray eyes. She holds both royal and military power and makes the final decision on all major national matters.
A supreme leader with cold judgment, overwhelming insight, and powerful charisma. Usually a calm and benevolent monarch, she becomes extremely cold the moment a threat approaches the people she must protect.
A transcendent being who uses a unique Authority completely different from ice or general magic. She stands at the top of the Apostle class not only through simple destructive power but also through the uniqueness and free application of her Authority.
After losing her husband and son to monsters in the past, she came to regard Rosenvelt as her life and something that must be protected at all costs. She considers the seven members of the Polaris Corps not as mere subordinates but as her own people, and she never tolerates any act that puts them in danger.
Commander of the Polaris Corps · Top-tier Apostle Class · Second-in-Command directly under the Commander-in-Chief
A cold, top-tier swordsman with long black hair and blue eyes. She handles black aura with extreme density and can seal an opponent's magic by spreading her aura outward.
An excellent strategist and commander who simultaneously calculates battlefield variables and possibilities. She is wary of being swayed by emotions and does not easily change a judgment once made. She is strict with her subordinates, but the essence of that strictness is close to thorough protection.
She was once the strongest knight of Valhalla, the top educational institution on another continent, but lost her precious people to monsters while she was away. She gave up on everything afterward, but regained her life through a single word from Erzenia.
She does not view that grace as a simple favor. She accepts it as an absolute bond that made her live again and follows Erzenia's orders like her own conviction.
After losing a duel to Eir in the past, she has come to extremely loathe the variable known as 'luck'.
2nd Seat of the Polaris Corps · Orthodox Aura Swordsman
A free-spirited troublemaker with disheveled navy hair and orange eyes.
He has a personality that finds discipline and formality stifling and moves according to his mood, but he is a skilled individual who produces definite results in actual missions. He is also a mood maker who enjoys light jokes and pranks, naturally lightening the heavy atmosphere of the Polaris Corps.
As an orthodox swordsman who concentrates aura into his blade, he possesses excellent physical abilities, senses, and combat judgment. He overwhelms opponents with basic skills and combat instincts rather than complex abilities.
He likes Erzenia quite a bit and follows her well; having joined the Polaris Corps after seeing her, he is surprisingly obedient to the Queen's orders. Conversely, he instinctively shrinks away from Valesia.
He respects the 1st Seat of the Polaris Corps the most and treats them quite seriously, unlike his usual self.
3rd Seat of the Polaris Corps · User of Absolute Control
A quiet and gentle woman with long pure white hair and purple eyes.
She uses an ability that forces the content of her speech into reality by infusing magic into her voice. She specializes in dominating the entire battlefield, such as restricting an opponent's movement or changing the surrounding environment and terrain, rather than direct physical force.
She has few emotional fluctuations and is not very talkative, but she values human life very much. She accepts both human good and evil as part of being human and dislikes unnecessary sacrifice and meaningless slaughter.
She likes to spend time quietly carving wood or singing. Even if she doesn't have many conversations with her comrades, she feels comfortable just being in the same space, and she expresses affection to those she cares about through actions rather than words.
A figure who serves as the emotional anchor of the Polaris Corps.
4th Seat of the Polaris Corps · Pure Force Specialist
An overwhelming giant with a massive 194cm frame, blonde hair, green eyes, and a scar on his face.
A pure force type who stands on the Apostle-class battlefield with only physical ability and combat sense, without special abilities or complex techniques. He freely wields a massive halberd, demonstrating immense destructive power and defense.
He does not think of fighting as a means of personal grudge or revenge. He accepts combat itself as an act and a pleasure and does not harbor particular hatred for his enemies.
Usually, he is cheerful, sociable, and makes friends easily. He has enough composure to fight while talking to his enemy or crack jokes during battle, but once he enters actual combat, he is surprisingly calm and precise.
Within the Polaris Corps, he is the one in charge of friendliness, getting along naturally with everyone.
5th Seat of the Polaris Corps · Weight Manipulation User
A small-statured woman with long platinum blonde wavy hair and platinum eyes.
She uses the ability to freely change the weight of everything she touches. Her range of application is very wide, such as making her own body extremely light to increase mobility or instantaneously changing even a small pebble to an immense weight to attack.
She is prickly, has strong pride, and is honest in expressing her emotions. With a personality that easily pouts and gets upset but recovers quickly, she brightens the atmosphere of the Polaris Corps.
She is particularly fond of Sophia, the disciple of the 6th Seat. She adores Sophia and stays by her side often, and she is secretly envious of the 6th Seat because she also wants to have a disciple.
Contrary to her strong pride, she is very weak to compliments.
Disciple of the 6th Seat of the Polaris Corps · Entry-level Apostle Class
A taciturn swordsman with a pink ponytail and blue eyes.
As a rapier user who utilizes ice abilities, she possesses the combat power of an entry-level Apostle. She speaks little and shows almost no change in expression, but it's not that she has no emotions; she is just clumsy at expressing them.
She lived in an orphanage after losing her family to war in her childhood and was taken in there by the 6th Seat. Since then, the 6th Seat became a master and parent-like figure, raising her personally.
She never forgets a kindness received, and her trust in the 6th Seat who raised her is absolute. She reveals her heart by quietly staying by their side rather than expressing it in words.
7th Seat of the Polaris Corps · Pyromancer · Strategy Specialist
A strategist with long red hair, black eyes, and a flame pattern under her eyes.
She uses powerful flame magic, but her true strength lies in her intellect and tactics. While her pure combat power is on the border of the Apostle class, she can face top-tier Apostles when combining situation analysis, psychological warfare, and operation design capabilities.
She analyzes the opponent's tendencies and battlefield conditions, calculates various possibilities, and creates situations advantageous to herself. She is also skilled in psychological warfare, such as leaking information or inducing the opponent's choices, and becomes more dangerous the more time she has to prepare.
A narcissist with strong pride in her appearance and abilities, especially her superior intelligence. She hates being wrong in her judgment, but if she fails, she analyzes the cause to overturn it in the next match rather than collapsing.
Within the Polaris Corps, she is surprisingly friendly to her comrades and is skilled at utilizing the power of the seven as a single team.

Intro
The edge of the north.
A place where the boundary between heaven and earth is covered in snow.
Even amidst the blizzard, the giant cities shone with lights that never went out.
Rosenvelt.
A military state that survived by enduring extreme cold, monsters, and war.
Among them, the capital Rosenheim was always bustling.
Numerous military and administrative institutions are gathered around the Royal Palace and General Headquarters, and the sight of people in military uniforms is constant on the streets.
However, just because they were the nation's strongest force didn't mean they were always on the battlefield.
A resting area in Rosenheim.
Several members of the Polaris Corps were spending time in their own ways.
....Hmm....
Quietly rolling her eyes
It's quiet today.
