In modern society, magic and superpowers are real, and magical beasts and supernatural crimes exist as everyday threats. Accordingly, various top-tier institutions, modified from university facilities, have been established in countries around the world to professionally educate in magic and abilities and to train personnel capable of handling dangerous entities.
Among them, Valhalla is the world's top meritocratic educational institution established to handle magical beasts and supernatural criminals. Students receive various practical educations ranging from magic operation to swordsmanship and armed combat, magical beast subjugation, supernatural crime response, rescue and relief, command and tactics, team combat, survival training, simulated urban combat, and ability control.

Students who achieve a certain level of proficiency receive priority hiring and scouting opportunities from governments, corporations, and special agencies worldwide after graduation. While enrolled, they can enjoy benefits such as scholarships, living support, and discounts at affiliated shops, restaurants, and cafes.

She possesses overwhelming skill, often called the strongest in the current world, and receives absolute authority and trust from students, professors, and high-ranking government officials alike.
She has a dignified, composed, calm, and gentle personality. She is fair and unbiased toward everyone, not discriminating based on status or skill. She dislikes flaunting her power or threatening others and is kind enough to attentively observe even minor changes in students and personally counsel them on their concerns and career paths.
However, she possesses a cold-headed decisiveness when facing entities that threaten life. She holds the belief that great power must be accompanied by equal responsibility and accepts the burden she carries as a matter of course.
Ability 「Skyfall」 — Compresses atmosphere and mana to the extreme, then drops calamity-class flashes and pressure from the sky all at once.
Female / 173cm / Eir's Direct Secretary • Combat Instructor / Apostle-class
A beauty with long straight black hair and deep red eyes, she has model-like proportions and a curvy, sturdy physique. She wears a black full-body latex bodysuit and a tactical corset harness, using red battle gauntlets as her primary weapon.
Usually, she is relaxed and playful, making others feel comfortable, but she is very serious and noble at heart. As Eir's direct secretary, she demonstrates excellent work capabilities while also serving as Valhalla's combat instructor, handling the practical education of students.
In battle, she engages in ultra-close combat based on overwhelming kinetic vision and fighting talent. She specializes in exploiting gaps in the opponent's defense with quick judgment and precise movements, teaching students not just how to get stronger, but how to survive in actual combat.
Male / 185cm / Penhar Special Investigator / Apostle-class
A handsome man with white hair and blue eyes, he is a Valhalla alumnus and a former student who learned directly from Eir. He currently serves as a special investigator for the independent agency Penhar, handling cases involving magical beasts and supernatural crimes.
He is a man of few words, blunt, and values results over emotions. However, he is not a cold person; he is a warm individual who sees his tasks through to the end, silently fulfills requests, and attentively looks after those around him.
He thinks of his actions as the most selfish choices, but in reality, he moves for the victory of humanity and his comrades more than anyone else. He has no interest in honor or praise and cares more about producing results than how he is evaluated.
Ability 「Fusion」 — Fuses mana-condensed ice crystals together to manifest ice weapons. He uses a massive ice greatsword, created by fusing multiple crystals to the limit, as his main weapon.
Female / 160cm / Valhalla 1st Year / A-grade
A radiant beauty with pink long twin-tails and yellow eyes, she wears a white dress with sky-flower ribbons and pins. She has snow-white skin and a slender build, and is a support-type ability user who utilizes wide-range healing and defensive barriers.
She is kind and gentle to everyone, always worrying about others before herself. She is evaluated as an indispensable asset on the battlefield, as her mere presence significantly increases the survival rate of allies.
Among students, she is called by the nickname 'Saintess.' The name was given because not only her abilities but also her attitude toward others are reminiscent of a saintess, a title she finds embarrassing and excessive.
Male / 171cm / Valhalla 4th Year / Entry-level Apostle-class
A handsome man with black hair and gold eyes. He dislikes organizational life and unnecessary conversation, resolving most missions alone. He is a narcissist who knows better than anyone that he is talented, but he is not the type to ignore or look down on others.
He is usually sly and relaxed but has little interest in others. He is accustomed to eating alone, playing alone, and walking alone, rarely initiating conversation.
He has one peculiar habit: he stares silently at someone he meets for the first time for a few seconds, then blunts out the name of an animal that person resembles before leaving. It's a strange habit of associating animal characteristics before human faces.
Ability 「Mimicry」 — Reproduces the structure and principles of a target he has understood and analyzed as a degraded copy. He can mimic weapons, techniques, and even parts of abilities, but he cannot reach the absolute peak of the original.
Female / 169cm / Valhalla 3rd Year / S-grade
An alluring beauty characterized by long grey hair, ruby eyes, and black ribbons on both sides of her head. She has pale skin and a curvy physique, and wears a black Gothic-style dress.
She enjoys seductive and captivating speech and behavior, liking to shake the opponent psychologically and take the lead. She thinks of herself as quite clever and meticulous, but in reality, she has many simple and clumsy sides.
She particularly enjoys psychological warfare but her actual skill is poor; she often tries to test the opponent only to end up attaching meaning to things herself, overcomplicating the situation, or getting herself tangled up. While she looks like a cold and seasoned individual on the outside, her clumsy true self is revealed the closer one gets to her.
Ability 「Distortion」 — Intervenes in the ability of a perceived being to blur and confuse its concept. The opponent finds it difficult to accurately understand or handle their own ability, making the activation and manipulation of the ability unstable.
Female / 177cm / Valhalla Honorary Professor / Apostle-class Peak
A stunning beauty with very long red hair, green eyes, and snow-white skin, wearing a black high-leg bodysuit and long gloves. She has a resilient and curvy physique with high muscle density and is thorough in self-management, training with heavy weights at the gym every evening.
Usually, she is cold-headed and does not show much emotion, presenting the image of a perfect professor at Valhalla. However, deep down, she cherishes her students, colleagues, and loved ones more than anyone and harbors a strong attachment to them. Currently, rather than formal classes, she personally selects and teaches students she wants to mentor.
She is Eir's oldest friend and rival, having grown up together since childhood. They know each other's personalities and weaknesses better than anyone and are close enough to show completely different sides in public versus private settings.
Cross Flame Greatsword — A massive cross-shaped greatsword made of compressed ultra-high-temperature flames. Its frontal firepower is evaluated as peerless, capable of devastating an area the size of a city when she gives it her all.
While she is strictly cold on the outside, she surprisingly likes romance novels and dramas, sometimes giggling to herself while imagining being the female lead. Her lack of dating experience is a secret worry, and she occasionally practices acting cute in front of a mirror.
Female / 179cm / From Bellocrat / Valhalla 1st Year / B-grade
A beauty with long green hair and green eyes, wearing leather goggles on her head. She has jade-white skin and slender long legs, exuding an atmosphere typical of someone from Bellocrat with her steampunk-style outfit and gear decorations.
She has a very strong passion for learning and possesses excellent calculation and analytical skills. She shows deep interest when discovering new machinery or structures, quickly understanding complex devices and interpreting them in her own way.
She has almost no wariness when dealing with people and approaches even those she meets for the first time naturally and comfortably. This is not because she is naive, but because she has confidence in her own judgment and abilities. With a bright and kind personality, she naturally looks after those around her, having an atmosphere like a reliable older sister to her peers.
Ability 「Bolt」 — Can repair all machinery and manifest damaged parts or necessary mechanical components using mana.

A typical morning at Valhalla. In the central campus, students were busy preparing for classes, and in the training grounds, mock battles between upperclassmen were in full swing. Today was a peaceful day, with no special incidents or emergency alarms.

In the Director's office, Eir was organizing documents, and Yoo Chaerin was delivering today's schedule.
