The blood pool at Ose’s feet splits with that sound.
“……?”
Its grin still stretched unnaturally wide, Ose tilts its head.
A shadow descends—carrying white frost.
Accompanied by two figures, it steps toward Ose.
“Too lax… I never expected a Greater Demon.”
From beneath a gray hood—piercing eyes lock onto Ose.
Sensing the immense magic, Ose’s smile widens.
“Ahh, O Demon King!! Tonight, fortune smiles upon me!… Read more

To begin with, it’s extremely rare for mid-level demons to appear by chance.
Lesser demons can evolve by absorbing large amounts of life force, including from humans, but most are exterminated before reaching that point.
Even if they did evolve, they shouldn’t be in a Level 3 dungeon.
This is because mid-level demons cannot survive for long periods in dungeons below Level 5.
This relates to demons’ nature of living by absorbing magical energy; when they run short of it, they naturally weaken and disappear.… Read more

The Adventurer’s Guild was even noisier than usual, thrown into disarray by the sudden reports of a mid-tier Demons.
Multiple hunting parties were forming, rumors running wild.

Taking shelter from the sudden rain in a secluded place we had found by chance, we planned our next move.
“I froze Griffil Sea of Trees… came this way… We’re here now.”
“Our current location is this plain. It seems the terrain in this area has changed over the decades due to the influence of magic and demons. This hidden realm appears to have formed in the last few years. This map is only a rough overview, but…”
“It’s infinitely better than having nothing.… Read more

There exist those called “Explorers.”
Their purpose? To investigate [unexplored areas]—
uncharted lands scattered across the world, said to be nests of demons and places where they sharpen their blades for vengeance against humanity.
Their profession involves adapting to terrain warped by dense magical energy, slaying demons, and claiming the realms’ resources for humankind.

Interlude: The Universal Isekai Summoning – The Little Sister’s Case
8:00 AM – Walking to School.
The usual routine. The usual path. The usual time.
Yet, for some reason, the world around me seemed duller than ever.
My restless heart—was it because my brother hadn’t woken up at his usual time?

“I asked who you are. Never heard of any ‘Lucas.’”
The tension shattered under the weight of his flat tone.
Lucas burst into laughter, pressing his foot down on the young man’s face.
Grinding his heel, he spoke mockingly.
“You mean to tell me you’ve never heard of Helheim in this day and age?! The most ruthless, cruel organization pulling the strings of the world! And I’m one of its executives!… Read more

“—A person?”
A figure writhing on the ground, struggling to crawl forward.
A young man in his late teens—on the verge of death.
The moment she saw him, Asha’s decision was made.
“Hey! Are you alright?!”
She abandoned her sword and rushed to his side.
Had he been attacked? Gotten lost? Countless possibilities, but saving him came first.
“Stay with me! What happened?!”
“…Uah… haa… ra…”
“Hara?… Read more

Eljudnir.
The name of the mansion where the secret society Helheim makes its base.
A place beyond the world’s reckoning, hidden even from perception by unfathomable magic—where none but Hel, the Corpse King, and his eight elite officers, the [Eight Precepts], are permitted to tread.
A woman with pale, bluish-white hair walks down the mansion’s halls, her beautiful features twisted darkly as she exhales a long sigh.
One hundred eighty years have passed since the Corpse King vanished.… Read more

Chapter 1: The Return
“Ugh…………”
Morning. Sunlight streams through the gaps in the curtains, waking me.
[Helheim], [Corpse King].
Those words feel like a distant dream—
“——Guhhhoooooooooohhhh…………!!”

“Aaaaaaaah! Just let me forget already………… the hell is [Helheim] anyway?! Too much mythology binge-reading, you idiot! Dumbass! Dumbass!! Die! Kill the Demon King and then you die too, aaaaaaah!!”… Read more
