The deepest, northernmost part of Bayview’s ocean was perpetually frozen, and in these frozen lands stood a forbidden area uncharted on any map.
No seafarer would dare venture these parts of the ocean, not even if that was the last thing they did, for in the northernmost part of Bayview’s ocean stood its sturdiest penitentiary.
It cost a hundred billion and a century to build, but it was worth it, for it eventually became the strongest prison in Bayview. It was built far, far out in the sea, at an altitude of one thousand meters below sea level.
It was gigantic, tightly shut, and made from the toughest alloy in the world, making it indestructible. Its security level was ten, and a hundred thousand armed units patrolled it all year long. The prison was also equipped with the world’s most advanced weapons, and there was even an aircraft carrier above the prison.
Ever since it was erected three centuries ago, no prisoner had ever escaped it. Every single inmate in here was feared throughout Bayview, and some by the world.
The inmates were also ranked in this prison. S-rank inmates were usually internationally wanted fugitives, SS-rank inmates were usually a threat to the world, while SSS-rank prisoners were walking, breathing disasters.
SSS-ranked inmates were the highest-ranked inmates in every nation’s prisons, with each nation housing one or two at the most. However, Demon’s Dungeon house a hundred SSS-ranked inmates.
It was, of course, the most fearsome prison around Bayview, but that wasn’t all. It might be unbelievable, but Demon’s Dungeon housed an SSSS-ranked inmate. That prisoner was truly a man who must not be named.
Demon’s Dungeon was also called the Eighteen Levels of Hell. In other words, it was split into eighteen floors. The deeper the floor, the more terrifying the inmates there were.
There was only one man in the eighteenth level of hell, and it was none other than Northern Demon, the only SSSS-ranked inmate in Bayview. He was recognized as the king of darkness by all the SSS-ranked inmates, and officially recognized by the wardens as the strongest individual they had seen over the last three centuries.
There was one rumor that flew around the prison. ‘There are two things you shouldn’t look directly at. One, the sun. Two, Northern Demon.’
He was far, far stronger than all the other inmates, and that was why he was an SSSS-ranked inmate. That was why he was locked up on the eighteenth floor.
That day, he broke another record. For three hundred years, no prisoner could escape the prison, but Northern Demon managed a feat none could ever hope to do.
The cold, cold doors of the depths of hell yawned open, and out came a man in black. There were no chains on him, for nobody could lock him down in here.
Ever since he was locked up, Northern Demon came and went as he pleased. Sometimes he’d even leave the prison to get some fresh air. Thanks to him, the depths of hell became nothing more than a joke.
That day, the leader of the Avengers came to pick him up. That day, he could finally leave the Demon’s Dungeon.
“Goodbye, Northern Demon!”
“Goodbye, Northern Demon!”
…
All the prisoners knelt before him, sending him off. It was a freezing hell, one where only demons remained, but the prisoners took to the demon as their god. On the day of his departure, they gave him a sendoff befitting of a king.
When he came to the first floor, the warden of the Demon’s Dungeon, Aidoneus, was already waiting along with a hundred men. Along with them were dozens of inmates in their prison uniform, who acted as representatives of all the prisoners here.
“Northern Demon, you may call upon us should you need any help. We’re Bayview’s most powerful assassin organization.”
“Northern Demon, you may call upon us should you need any help. We’re Bayview’s most powerful mercenary group.”
