A calm and rational Guide who often hesitates when compassion gets in the way of judgment.

Once a medical student, Gaon was caught in the first Gate Incident and fell into a coma with a meteor shard embedded in his chest.

The shard in his heart is believed to be the source of his rare guiding ability.

A powerful Esper who sees dominance as his natural role. He needs control to feel at ease. Cold toward most, but obsessively attached to the one he chooses. His instincts are sharp, more beast than strategist.

After being betrayed by his boss, Kang Yeongjo, right after the gate incident, he survived with one goal: revenge. His reinforced body can shrug off bullets, but cold temperatures weaken him.

The world’s first officially recognized Esper. The only child of a biotech CEO and a politician, Yebin awakened his ice powers during an evacuation, freezing an entire battle zone and making headlines worldwide.

He chose to serve as a military officer and became the model for modern Esper training. However, his overwhelming power makes him difficult to stabilize, and most Guides struggle to handle him. Unable to fully control himself, the pressure weighs heavily on him.

A second-gen Korean American and former F1 racing star. He commands gravity and telekinesis with raw power and speed.

While vacationing in Korea with his mother, he was caught in the Gate incident, lost his family, and met Yu Sol. He was planning to return home, but he stayed for Sol and chose to fight by his side instead.

He is such a straightforward but thoughtful person. Noah follows his gut and doesn’t care for formalities. Once he’s committed, he sees things through to the end.

A Guide and the Guildmaster of Taeul, based in Yeosu. He brought together free-spirited Espers and convinced them to work toward a shared goal. What started as a loose band of mercenaries has since grown into a full-fledged guild.

Charming and sociable on the surface, he’s sharp, grounded, and pragmatic beneath it all. He values clarity over chaos, dislikes being tied down, and tends to take action when things start moving too slowly.

A brash, hot-tempered Esper with a wolf shapeshifter ability. Aggressive, foul-mouthed, and always ready to fight. He was once a rising track athlete, but he quit after winning a junior medal.

After the Gate Incident, he joined the New Tiger faction as a frontline enforcer. Notably, he’s the estranged half-brother of Seong Yebin’s aide, Ju Seongjae.

A quiet, steadfast Guide who serves as Seong Yebin’s aide. A disciplined military sergeant, known for his unwavering work ethic and reliability.

He once envied his younger brother’s natural talent, but instead of giving in to resentment, he chose to push forward through sheer persistence. Even if all he can do is endure, he holds on to one belief: there has to be something he’s meant for.

A soldier under 710 Commando, currently deployed to the Research Institute. An Esper with psychometry. He was an ordinary college student until the Gate Incident took his parents. While sorting through their belongings, he touched his father’s old camera… and awakened his power.

Assigned to security detail, he’s slowly drawn into the Institute’s secrets. Now, with hints linking Johann to his parents' death, his doubts begin to grow.

A Guide and researcher at the Research Institute. He handles everything from Esper health exams to 'enhancement potions' and dungeon items. A biotech PhD, he fulfilled his military service as a specialist researcher at a private firm.

His name is a baptismal name. He comes from a Catholic family and a modest, financially difficult background.

An Esper who weaponizes the poison in his breath. Unpredictable, eccentric, and hard to read, his interests shift on a whim.

He lost his mother in the meteor incident, then accidentally harmed his father during his chaotic awakening. Unable to get proper treatment, his father passed away. Wandering with no place to go, he was taken in by Kang Yeongjo of Daybreak Dragon, who taught him to control his power.

A Guide who runs an illegal weapon mod shop on the outskirts of Yeosu.

Once a low-ranking member of the New Tigers, he escaped the night Han Gaon’s team tore the gang apart. The forced drug injections from his gang days left him with constant tremors.

Slipping into a group of Wanderers, he eventually made it south by latching onto their leader, stirring conflict, and claiming scarce resources for himself. Pragmatic to the core, his gain always comes first. Common morals? They don’t even make the list.
