Chapter 4:
The mission appeared the moment Yuki woke up.
Not while working. Not while training.
The system waited until his mind was clear.
[New Mission Issued: Two-Step Mission]
Yuki sat up slowly, already tense.
Step One: Become an Adventurer
Objective:
• Register at the Guild
Step Two: Enter the Dungeon
Objective:
• Kill 10 Goblins
Reward (Upon Full Completion):
• Byakugan
• Hyuga Clan Taijutsu
Failure Penalty:
• Mission Lock (Temporary)
Yuki stared at the words for a long time.
"…So that's it."
There was no way around it this time.
Registering at the Guild meant visibility. A name on record. A path that couldn't be walked back easily.
And the Dungeon?
That was where people died.
Still, the reward made his chest tighten.
The Byakugan wasn't just a dojutsu. It was perception beyond normal limits. Vision through walls. Near-perfect awareness. Combined with Hyuga taijutsu…
"I wouldn't just survive," he said quietly. "I'd control the fight."
By midday, Yuki made his decision.
He used Henge no Jutsu, altering his appearance into a slightly older version of himself. Nothing flashy. Just enough to avoid attention.
Then he headed for the Guild.
The Guild
The building was larger than he expected. Clean stone walls. A constant flow of adventurers entering and leaving.
Yuki waited in line, listening.
Complaints about monster drops. Arguments over party shares. Casual talk about injuries that would have crippled normal people.
When it was his turn, the receptionist barely looked up.
"Name?"
"Yuki."
"God?"
"…None."
That earned him a glance. A short one. Not surprised. Just tired.
"First time?"
"Yes."
She slid paperwork across the counter. Basic information. Warnings about the Dungeon. Legal responsibility.
No falna meant no blessing. No status. Just a civilian permitted to enter the Dungeon at their own risk.
Yuki signed.
The receptionist stamped the form.
"Don't go below the first floors," she said flatly. "And don't expect help."
"I won't," Yuki replied.
The system reacted immediately.
[Step One Completed.]
Yuki didn't feel relief.
Only pressure.
The Dungeon
The entrance loomed beneath the city like a massive wound carved into the earth.
The air was colder inside. Heavier. The stone walls pulsed faintly, as if alive.
Yuki didn't go far.
First floor. Wide tunnels. Weak monsters.
Still lethal if careless.
It didn't take long.
A goblin crawled out from behind a broken pillar, green skin stretched tight over its thin frame. Rusty blade in hand. Yellow eyes locked onto Yuki.
Yuki didn't hesitate.
A burst of speed. Body Flicker.
The goblin barely had time to react before a wind-enhanced strike crushed its throat.
The body dissolved into black smoke.
1/10 Goblins Defeated
Yuki exhaled.
"Focus," he muttered.
The fights blurred together after that.
Fire Release scorched narrow tunnels. Earth walls blocked ambushes. Wind blades cut where blades couldn't reach. Water bullets crushed skulls with brutal efficiency.
The goblins weren't strong.
But they were numerous.
And cruel.
One slash caught his arm. Another nearly reached his leg. Pain reminded him that mistakes still mattered.
When the tenth goblin fell, Yuki leaned against the wall, breathing hard, blood dripping from a shallow cut on his shoulder.
The system spoke.
[Step Two Completed.]
The Dungeon felt quieter.
Almost like it was watching.
The Reward
Yuki barely had time to react.
Pain exploded behind his eyes.
He dropped to one knee, clutching his face as something changed. His vision sharpened violently. The world peeled open.
Stone. Mana flow. Movement through walls.
Everything was visible.
When he looked at his hands, he understood them differently. Chakra pathways lit up in his perception like a living map.
His stance shifted on instinct.
Balanced. Grounded. Precise.
Knowledge flooded in. Gentle Fist principles. Chakra strikes. Internal damage over brute force.
Byakugan.
Hyuga Taijutsu.
Yuki slowly stood.
He activated his vision again.
The Dungeon's walls no longer felt like obstacles.
They felt transparent.
"…This is dangerous," he said softly.
Not the power.
The temptation.
He deactivated the Byakugan and turned toward the exit.
Today, he had crossed a line.
Registered. Entered the Dungeon. Killed monsters.
He was an adventurer now.
Not a strong one.
Not a famous one.
But for the first time since arriving in this world, Yuki wasn't just preparing to live.
He had taken his first real step forward.
And the Dungeon had noticed him.
