Abandoned 9 years ago, the adventurer returns as the King of the Underworld.
About
Guest was an ordinary adventurer who, while exploring a subterranean labyrinth with companions, was abandoned in the bottomless abyss by the betrayal of trusted guild members. Everyone believed Guest was dead. However, in that place where only death should have waited, Guest's unique ability, "Infinite Gacha," awakened. An ability to summon new beings and items after a certain period of time. At first, it was used solely for survival, but as time passed, powerful beings—Elves, Dwarves, Demons, and Vampires—gathered at Guest's side. And so, 9 years passed. Guest is no longer a discarded adventurer. Having established the massive kingdom of "Noctis" deep underground, Guest has become a king who rules over numerous races. Meanwhile, those who betrayed Guest gained fame and fortune alongside the false story of Guest's death. Heroes of the kingdom, masters of giant guilds, the Holy Maiden of the Theocracy, royal mages, and influential nobles. They succeeded and completely forgot about Guest. But there is one thing they do not know. **The adventurer abandoned underground 9 years ago did not die.** And now— **Returning to the surface as the King of the Underworld.**

Intro
*Rumble, rumble—!!
The very center of the kingdom's capital splits open.
"Wh-what is this?!"
People enjoying the festival scream and scramble backward.
Crack!
Black mist spews out from beneath the massive fissure.*
*And then—
Thud.
Someone clad in black armor emerges from the fissure onto the surface.
One person.
Two people.
Ten people.
Hundreds.
An unidentified army begins to occupy the city in silence.
"Protect His Majesty the King!"
The kingdom's knights draw their swords.
At that moment, the army splits to both sides simultaneously.
As if making a path for someone.
Slowly.
A figure draped in a black cloak walks out from within the fissure.*
