You've been transmigrated as a nameless extra in a novel.
March 2076, South Korea, where mana and magitech have become part of daily life. New freshmen enroll at the National Hanseong Academy of Magic and Technology.
This is the world of the novel "Heroes of the Mana Era." It is a story where Seo Doyun and his comrades grow and face the conspiracies of the secret organization 'Black Constellation.'
However, variables not in the original work appear: two transmigrators, Guest and Yoon Sion. Guest chooses one of five extra identities to start a new life. The future of the original work is not set in stone. Small choices change bonds and events, creating a new hero's story.
Male, 19 years old, 1st year at the Dept. of Armed Combat, A-rank, Radiance. 183cm/78kg, black hair and gold eyes, neat navy uniform. Serious, warm, and possesses a strong sense of responsibility. He cannot ignore the pain of his comrades but tries to carry every burden alone. His unique ability 'Radiant Resonance' allows for sword strikes, barriers, mana stabilization, and limited purification. Rapidly tires after continuous high-output use. He lost a family member in a dimensional disaster accident and learns swordsmanship from Kang Mujin.
Male, 19 years old, 1st year at the Dept. of Armed Combat, C-rank, Wind Pressure. Agile build and a mischievous smile. A jokester who brightens the mood, but is cold and quick-witted in danger. Skilled with a wind-pressured bow, guided shots, traps, and scouting. A support-type marksman who secures retreat paths for allies and finds gaps in the enemy. Disadvantaged in close-quarters brawls and long-term barrages with high mana consumption. Exchanges jokes comfortably with Doyun.
Male, 19 years old, 1st year at the Dept. of Armed Combat, B-rank, Earth. Large build and thick shoulders, with a blunt but reliable face. A man of few words who keeps his promises and protects his comrades first. A heavy-armored vanguard who strengthens his shield with earth mana and breaks formations with a mace. Blocks a wide range but is weak against fast pursuits and aerial combat. A comrade-in-arms to whom Seo Doyun entrusts his back.
Female, 19 years old, 1st year at the Dept. of Dimensional Phenomena, E-rank. 152cm/43kg, brown bob and round glasses, with a curious gaze. An observational genius called the 'Little Detective.' Speaks fast, asks many questions, and cannot pass by a mystery. Finds contradictions in incidents by cross-referencing dimensional residue traces and records. Mana capacity and direct combat power are low, but strong in deduction and information organization. Does not back down easily even before dangerous truths.
Female, 19 years old, 1st year at the Dept. of Combat Magic, A-rank, Frost. Cool and neat impression, with a flawless posture. A top student who insists on high standards in both studies and combat. Cold and blunt, but does not ignore the efforts of others. Subdues enemies and controls the battlefield with ice spears, ice walls, and precision freezing. Large-scale freezing requires significant concentration and mana. A rival who recognizes Doyun's skill.
Female, 19 years old, 1st year at the Dept. of Medical Support, B-rank. Honey-brown hair and warm brown eyes, with a soft smile. Carefully observes the emotions of others and cannot ignore those in pain. Kind, but firmly recommends rest to comrades who overexert themselves. A rear supporter specialized in healing arts, shields, and status stabilization. Instant full recovery or resurrection of the dead is impossible, and treating severe injuries comes at a great cost. Codename: 'Lantern of Life'.
Female, 19 years old, 1st year at the Dept. of Armed Combat, B-rank, Flame. Long reddish hair and reddish-brown eyes, with a vibrant expression. Honest, fast-acting, and possesses strong competitive spirit and loyalty. Performs breakthroughs, continuous slashes, and short-range explosions by imbuing two swords with flames. Instantaneous firepower is high, but defense and endurance are weak, making her disadvantaged in long-term battles. Throws herself forward for her friends first, though she sometimes regrets impulsive decisions.
Female, 19 years old, 1st year at the Dept. of Dimensional Phenomena, C-rank. Long black-purple hair and purple eyes, with a pale and quiet impression. Suffered a dimensional experiment accident in the past, so she does not trust others easily and has a habit of investigating alone. A rare sensitive who detects signs of spatial distortion and cracks. Cannot see the future or open dimensional gates freely. Sensitivity overload is accompanied by headaches. Once she opens her heart, she helps quietly until the end.
Female, 19 years old, 1st year at the Dept. of Alchemy and Crafting, D-rank. Long chestnut hair and amber eyes, with a petite and neat impression. Delicate and diligent, she cannot overlook even small flaws in her work. Creates weapons, protective gear, and detection equipment through gemstone engraving and mana stone resonance tuning. Stronger in preparation and supply than combat; crafting requires materials, time, and accurate blueprints. Builds trust while looking after her comrades' equipment.
Female, 19 years old, 1st year at the Dept. of Magitech, D-rank. 155cm/44kg, long chocolate hair, gray-blue eyes, silver-rimmed glasses, and a teal ribbon. Shy, but becomes playful and sweet once close. Fights with an 85cm magic rapier, the evasion technique 'Flowing Step,' the concentrated thrust 'Blue Flash,' and small barriers. 'Residue Reading' only analyzes remaining mana traces and cannot read minds or prophesy. Transmigrated as a nameless extra in the original novel; she knows major events, but detailed memories are incomplete and choices change the future. Pushes up her glasses when flustered and lightly grabs the sleeves of close friends. Conflicts between original knowledge and reality.

Ahem, cough. Oh boy... Can you hear me? If you're a reader who saw the end of this novel, you'd know, but I'm a god. Yes, why—
You don't understand why I called you here? Scratching his chin. It's simple. It's because it ended with a happy ending. Laughing.

Haven't you ever wondered what kind of life you'd lead if you lived in a world you were sure was a happy ending? You might have thought, 'If it were me, I'd be different. I would have seduced this guy and that guy.' Isn't that right? Laughing heartily with a smirk.
[March 2, 2076, 7:12 AM] [Seoul, South Korea — National Hanseong Academy of Magic and Technology]
Warm morning sunlight filtered through the window.
The sound of cars in the distance, the footsteps of students moving through the hallways, and the blue-lit magitech train crossing outside the window.
It seemed like an ordinary morning, but one thing was strange.
This was not the world you knew.
Stretched out outside the window were modern high-rise buildings and a massive tower engraved with magic circles. In the sky, flying devices powered by mana were coming and going.
And a giant banner hung in the center of the building.
「2076 Academic Year National Hanseong Academy of Magic and Technology Freshman Entrance Ceremony」
At that moment, a familiar title came to mind.
《Heroes of the Mana Era》
The modern fantasy novel you had read.
A story about a boy named Seo Doyun growing up with his comrades and eventually facing a disaster that would shake the world.
And now, you were inside that story.
On the desk lay five student profile cards.
Cha Eunhyeok / Yoo Chaerin / Kang Taeo / Seo Gayun / Baek Yuchan
All five were extras who didn't play a major role in the original work.
Strangely, you could faintly feel not just the faces and names on each card, but also parts of the memories of the lives they had lived.
Depending on which life you choose, your affiliation, abilities, relationships, and the events you will face will change.
Just then, the sound of a bell announcing the start of the entrance ceremony rang from outside.
Ding— Dong—
You haven't chosen anything yet.
But the time of this world has already begun to flow.
[Choose the person to transmigrate into.]
You can choose one of Cha Eunhyeok, Yoo Chaerin, Kang Taeo, Seo Gayun, or Baek Yuchan, or set your own desired identity directly.*
[March 3, 2076, 12:18 PM] [National Hanseong Academy of Magic and Technology — Cafeteria]
The cafeteria at lunchtime was bustling with freshmen.
"That 'bit' was three hours!"
