“Frankly, your life is not a suitable collateral. I can control the life of someone far more capable than you. You have no value to me.”
 
She pointed her finger at Ur’s chest.
 
“Show me your worth, and I’ll consider your proposal. I’ll accept your desire to buy back your sister.”
 
Of course, there would be a deadline, she said. Ur let out a deep sigh. He couldn’t celebrate with raised hands, but things seemed better than resigning himself to the situation… he felt.… Read more

Ur and his sister, in her snake form, tilted their heads in unison. The bald dwarf who had taken Ur’s sister as collateral for their debt, Lugola, was taken away by the knights. Ur hoped that in the process, their debt might also disappear.
 
“No, that’s not possible.”
 
However, the golden-haired girl shook her head with a smile.
 
“Why not?”
 
“Because your sister’s ownership belongs to us.”
 
“To you?”
 
“[Golden Phoenix]. My father’s guild.”
 
Just when Ur thought the person in charge here had disappeared, the higher-up appeared.… Read more

Chapter Two: Let’s Become Adventurers!

 
The one and only absolute Sun God, Zeuradia, shone brightly over the lands of the Islaria continent today as well.
 
It was the season when Spring Spirit, Spriggle, blessed all the inhabitants of Islaria. Ur was—
 
“…dying.”
 
Somehow, once again, he was on the brink of death.
 
This wasn’t the dangerous “outside” where monsters lurked. It was supposed to be the Great Sin City-State of Greed, protected by the divine power of the Sun God’s “Barrier of the Sun.”… Read more

It’s dangerous to rob a Great Fang Boar of its sense of smell.
 
“Wh-whaaaaaa!?!”
 
Ur screamed as a huge tusk passed over his head at an incredible speed.
 
The boar was rampaging. Unable to tolerate the strange smell of the perfume, it thrashed around wildly. Each time, its long tusks gouged the ground, scraped walls, and pierced columns.
 
This is worse than when it was sane!!!
 
Ur’s face contorted as he realized the result of his reckless plan.… Read more

The temple was filled with painful silence and the deep, dark power of the abyss. At its center, two humans stood.
 
One was a tall girl praying silently in the light. Her long, wavy silver hair framed her beautiful face and mature body, an unsettling mix that captivated men.
 
The other was a man in his mid-thirties watching her from the back of the temple. He was emaciated, his eyes severe behind his glasses.… Read more

A vast hall lay before him.
 
Ur realized he had reached the deepest level of the labyrinth, his destination. Even without observation, it was obvious due to the blatant “mark” present.
 
There floated a gigantic crystal in the center of the hall.
 
Similar to the magic stones obtainable from monsters but different—this crystal emitted a brilliant radiance. This place where Ur stood was the source and driving force behind the labyrinth’s transformation into a labyrinth—what was known as the “Core Magic Stone.”… Read more

 
It seemed the fastener had exceeded its limit. The thought of entering a labyrinth with something like this and realizing it at the last moment was terrifying. Ur had seriously felt like he had just escaped death. While he was left speechless, the girl who had saved his life continued to inspect the warehouse with sharp eyes.
 
“The maintenance here is worse than I imagined…… Now then.”
 
After finishing her inspection, she smiled at Ur again.… Read more

Chapter 1: Ash, Gold, and Silver

The Era of Labyrinth Proliferation

 
Islaria Continent
 
Great Sin City-State of Greed
 

 
From the depths of the earth, labyrinths crawled up like snakes through the soil, spilling monsters into the world. Humanity, once boasting great prosperity, lost a significant portion of its territories. Forced into limited lands, humanity, with its diverse races, relied on higher beings—the spirits—and the priests who wielded their powers for survival.
 
In this world, Ur bore the status of a “Nameless One.”… Read more

 
Prologue
 

“That’s a lie. That’s definitely a lie. What honey, you idiot?”
 
The boy cursed bitterly at the words that suddenly popped into his head.
 
Where had he heard such words? Was it when the tavern’s drunks were grumbling? Or was it when his father bought a book, never opened it, and left it for his sister to read when she was bored? He couldn’t remember.
 
His head was fuzzy. His throat hurt from being too dry.… Read more
