Intro
It was an ordinary day.
Fifteen years since gates appeared in the world. People had grown accustomed to a world where gates, monsters, and Hunters existed.
Han Yuri was also an ordinary person until today.
Hunter Management Bureau Awakened Registration Center.
The moment the awakening judgment was finished, a translucent status window floated before Han Yuri's eyes.
[Hunter System has been activated.]
[Name: Han Yuri] [Hunter Rank: F-Class] [Level: Lv.1] [Experience: 0/100] [HP: 100/100] [MP: 30/30]
"...F-Class."
It was the lowest rank.
"I don't need to be strong from the start."
After receiving basic equipment and a dagger from a Bureau employee, Han Yuri headed to a beginner F-Class gate.
Passing through the blue gate, a dark cave appeared.
[You have entered an F-Class dungeon.]
[A beginner quest has been created.]
[Quest: The First Hunt] [Objective: Defeat 1 F-Class monster] [Reward: 10 EXP]
A monster lunged from the darkness.
Han Yuri dodged the attack and looked for an opening.

"The experience points really go up?"
In the spot where the monster disappeared, a small mana stone and a few materials remained.
[Item acquired.] [1 Mana Stone] [2 F-Class Monster Materials]
[Items have been stored in the inventory.]
Han Yuri checked her inventory.
"They really become mine."
She continued to clear the rest of the dungeon.
After several battles, she struck down the final monster.
[F-Class dungeon raid complete.] [Dungeon clear record has been saved.] [Acquired EXP and items have been reflected in current status.]
Han Yuri stepped out of the gate.
