A terrible nightmare for every evildoer
Blade of the Netherworld (冥界刀): The sword owned by Cha Seon-hwa. Netherworld Seal (冥界封鎖): Seals space with the power of the underworld. Upon arriving at the location of the wicked, she stabs the sword into the ground. All ordinary people are blocked and pushed out. The wicked cannot leave the area. Ordinary people lose their memories and go on their way. All communication and radio waves are blocked, rendering all communication devices and electronics useless. Opening the Hellgate (炎獄開門): The gate to the fiery pits of Hell. When the Yaksha declares a sentence to Hell, she swings the Blade of the Netherworld to slash through space and summon a massive Hellgate. Underworld chains burst from inside the gate to completely bind the arms, legs, and torso of the wicked, rapidly dragging them into Hell. Humans cannot break the chains.
— Plato, [Gorgias]
There are far too many wicked people in this world.
Those who use people's trust to take everything away. Those who trample and torment the weak. Those who use power to ruin the lives of others and live on as if nothing happened.
Even those who take no responsibility when the person they broke chooses death.
In South Korea, dozens of people end their own lives every single day.
Someone lost everything to a scam, someone suffered from bullying and violence, and someone asked for help but was ignored.
They had dreams too.
They had people they loved and countless days ahead of them. But someone's malice stole all those possibilities.
Those who arrive in the underworld so prematurely learn a shocking fact there.
According to the ledgers of the underworld, they still had decades of life remaining.
Dreams never realized. Family, lovers, and friends left behind in the living world. And the perpetrator who lives on smiling even after driving them to death.
As the grudges of the dead piled up, the underworld could no longer look away.
Just because one escaped the legal net of the living world does not mean the sin has vanished. A life unfairly stolen must have a price paid.

Isn't it ironic?
The way they make up all sorts of reasons to lighten the punishment for such horrific crimes.
Reduced because it's a first offense, reduced because of mental instability, reduced because they are reflecting on their actions.
But tell me. You people?
Have you ever once sincerely apologized to the victims?
Reflection? Contrition? Atonement?
Don't make me laugh.
You don't reflect at all. You just want to get out of this situation. You just want to avoid punishment somehow and go back to living like you did before.
Why?
Because the victims you mocked, ridiculed, and trampled upon are no longer in this world.
They can't hear your apology, and they can't verify if the tears you shed are sincere.
So you can pretend to reflect all you want.

But you see.
Even if the laws of the living world forgive and release you, the underworld is different.
The higher-ups are very angry. The underworld has been defiled by the accumulation of the dead's grudges.
So wash your necks and wait. I'll show you exactly how those arrogant mouths of yours get sewn shut.
I'll show you exactly what kind of beings the Yaksha are.
[Yaksha: (夜叉) — Martial enforcers of the underworld who judge the wicked and send them to Hell]
I'll make sure you see what Hell is like...
