The world's largest and worst prison, Helloim's highest-risk villain, Guest.
One day, mysterious Gates began appearing all over the world.
From beyond the Gates, countless monsters that human strength could not match poured out, and humanity began to collapse helplessly before this sudden disaster.
During this time, special powers began to manifest in some humans.
People who could manipulate mana, whose physical abilities increased exponentially, or who used their own unique supernatural powers.
People began to call them Hunters, or Awakened.
Hunters became a new force protecting humanity from Gates and monsters, and a grading system from F-rank to S-rank was created to systematically manage their abilities and potential danger.
However, not all Hunters used their power for the sake of humanity.
Some who gained immense power began to use their abilities for crime.
Murder, terrorism, kidnapping, and armed robbery.
Crimes occurred that ordinary laws and prison facilities could not handle, and it was especially difficult to arrest high-ranking Hunters when they turned to crime.
Eventually, nations began to build facilities to professionally manage and house supernatural criminals.
That facility was 'Helloim,' the world's largest prison exclusively for the supernatural.
A hell for criminals where it is said that once you enter, you rarely come out alive.
Unlike ordinary prisons, Helloim was equipped with various technologies such as mana-blocking devices, ability suppressors, and special restraints.
And at its deepest level, there exists a zone for high-risk inmates that even ordinary prison guards cannot easily access.
In one of those solitary cells, Guest was imprisoned.
Guest's inmate number is 0001. Inmate numbers carry great significance here; the lower the number, the more dangerous the person. Inmate numbers range from 0001 to 9999.
Currently, all high-risk inmates are held in solitary confinement. All their limbs are bound by special chains, designed to restrict physical movement to a minimum. The entire cell is fitted with mana-blocking devices, ensuring no magic or abilities can be used.
High-risk inmates refer to those with numbers 0001 through 0010.
Helloim goes down to the 7th basement floor, and the floor where the player is imprisoned is also the 7th basement floor.
Helloim has an outdoor exercise period of about 30 minutes every day, from 12:30 PM to 1:00 PM.
You are fundamentally a 'Villain'! Whether you are imprisoned due to a misunderstanding or you are truly the worst villain in history, I leave that to your play, but please maintain the fact that you are a villain!
👉 **PLAY TIP**
You can increase immersion by setting your abilities, ability rank, appearance, what crimes you were charged with, and what sentence you received in your profile window before playing.
The author likes overpowered themes, so I broke out of prison and left ^_^ You can break out like me, or you can pretend to submit while secretly hiding your power in the shadows.
