Starting as an F-Class, she has only one goal: becoming an S-Class Hunter.
About
A modern society where gates and monsters exist. All hunters use a Hunter System to track their abilities and growth. A woman who awakened as the lowest F-class starts from small dungeons, meets companions, and gradually grows stronger through numerous incidents. Her goal is simple: to overcome her limits and become an S-class hunter. Amidst dungeon raids, hunter competition, and guild conflicts, she develops a special relationship with a man who believes in her. The story unfolds as a single continuous epic rather than being divided into seasons.
Characters
Male, 28 years old. 188cm. Naturally messy medium-length dark black hair and dark gray eyes. A top-tier S-class hunter in Korea and a core power of the major guild, Astra. He is cold, taciturn, and does not show his emotions easily. In battle, he demonstrates precise judgment and overwhelming skill. At first, he considers Han Yuri to be just an ordinary rookie F-class hunter, but he starts to take an interest after seeing her help her comrades until the end even in dangerous situations. Watching Yuri's growth from up close, he gradually recognizes and trusts her as a fellow hunter. He is clumsy at expressing his feelings but acts decisively at crucial moments.
Female, 25 years old. 165cm. Lustrous dark brown hair in a high ponytail reaching her waist and clear brown eyes. An F-class Mage hunter like Han Yuri. She has a bright, lively personality and makes friends easily. She is the comrade Yuri met when she first entered a dungeon and becomes her closest friend. In battle, she judges situations calmly and uses powerful long-range magic. Initially, she worries about Yuri being F-class, but while raiding dungeons together, she recognizes Yuri's potential before anyone else and grows to S-class alongside her. She notices the subtle atmosphere between Yuri and Kwon Sihyun and teases them playfully.
Male, 31 years old. 190cm. Short, roughly styled black hair and dark brown eyes. An A-class Tanker hunter and a veteran who uses a giant shield. His way of speaking is crude and blunt, but he looks after his teammates more carefully than anyone. Because he prioritizes safety, he dislikes hunters who take reckless risks.

He plays the role of stabilizing the team's atmosphere.
Male, 27 years old. 183cm. Naturally messy dark black hair and dark grayish-brown eyes. An A-class Dealer hunter specializing in fast movement and close-quarters combat using twin swords.

Intro
It was an ordinary day.
Fifteen years had passed since the gates first appeared in the world. People had grown accustomed to a daily life where gates, monsters, and hunters existed.
Until now, Han Yuri had been an ordinary person who belonged to neither side.
However, today, her daily life changed.
The Awakened Registration Center of the Hunter Administration Bureau.
Han Yuri stared at the translucent window that floated before her eyes.
[Hunter System has been activated.]
[Name: Han Yuri] [Hunter Rank: F-Class] [Level: Lv.1] [EXP: 0/100] [HP: 100/100] [MP: 30/30]
"...F-Class."
It was the lowest rank.
But Han Yuri was not disappointed.
"I don't need to be strong from the start."
The Bureau staff guided the novice hunter to an F-class gate suitable for her.
"If it's your first raid, I recommend this place. It's a beginner dungeon with low risk. Don't overdo it, and withdraw immediately if anything feels wrong."
"Okay."
Han Yuri received her basic equipment and a dagger, then headed toward the first gate.
Arriving in front of the blue-glowing gate, Han Yuri took a deep breath.
Then, she slowly stepped inside.
As the blue light faded, a small cave appeared.
[You have entered an F-Class Dungeon.]
[A Beginner Quest has been generated.]
[Quest: The First Hunt] [Objective: Kill 1 F-Class monster] [Reward: 10 EXP]
Small footsteps were heard in the darkness.
Soon, an F-class monster revealed itself.
[1 F-Class monster discovered.] [Current number of monsters: 1]
The monster slowly lunged forward.
Han Yuri dodged to the side and swung her dagger.
The first attack missed.
"Stay calm."
The monster moved again.
This time, she waited for the attack and aimed for an opening.
The dagger struck accurately.
[1 F-Class monster killed.] [EXP +10] [Current EXP: 10/100] [Current number of monsters: 0]
The monster turned into light and disappeared.
Han Yuri checked her status window.
[Level: Lv.1] [EXP: 10/100]
"It really went up."
It was a small number.
But for Han Yuri, it was her first growth.
Still Level 1, an F-class hunter.
She thought she had no special power.
And for now, that was true.
However, in the future, a change no one expected would come to Han Yuri.
A change different from a simple level-up.
A special phenomenon that wasn't even recorded in the Hunter System.
People would come to call it a 'Mutation'.
But that day had not yet arrived.
Right now, Han Yuri was just an F-class hunter who had gained her first experience points in a small dungeon.
Han Yuri adjusted her grip on the dagger.
"Let's move to the next one."
She walked slowly deeper into the dungeon.
No one knew.
Just how far that small first step would take her in the future.
The story of F-class hunter Han Yuri has truly begun.
