Chapter 1: A Fitting End For A New Begining
The last thing he remembers was his failure.
Failure of what exactly? The failure of freeing his people from the cycle of hatred that haunted them for years. When he finally found a way to free them from their burden, the very same people he tried to protect turned their backs on him, betrayed him, and they killed him. Those people were his friends, his comrades, and they fought against his ideals.
Their actions were nonetheless, justified.
Eren Yaeger knew that killing everyone outside Paradis was a downright villainous act. No matter which way one looks at it, he committed genocide, and he paid the price for it, by the hand of his friends.
A fitting end for monsters like him and got sent to hell and suffer from the consequences of his actions.
Hell.
A place where primal fears reside. The place where the first concepts of evil were created to haunt the Earth from the very first day. Concepts like slavery, torture, racism, and… war.
All of these concepts manifested in physical form and Eren could see that the religions in his world were no mere exaggerations. Monsters roam around endlessly, mauling other devils until there is no more than a puddle of blood remaining, fighting each other to the death, only for them to revive and repeat the process again.
He could see why Hell earned its name and reputation.
The sky that would normally have a clear blue color was replaced by countless doors. Each of them opened whenever a devil died and needed to be revived. They were the reason why the devils were effectively immortal. And they were destined to suffer for all eternity as soon as they arrived.
Eren knew this and yet he refused to give up. He kept fighting.
He didn't know what he was fighting for. He lost everything, his home, his friends, and his name. He had nothing to lose in hell. There was no reason for him to even try to fight.
Yet he still fought with his all against the terrors of Hell, because he felt that he must. There were monsters that were far stronger than him, The Darkness Devil, Guts Devil, Knife Devil… he could keep going for ages. No matter which titan he threw at those monsters, be it the Warhammer, or even the Founding, those monsters always overpowered him. Still, Hell never let him go, so he always came back and kept fighting. He has never died once since he arrived.
In his penance, he has fought against countless deformities. Monsters with thousands of eyes that were spread from its entire body, a pile of human heads that carried pustules from all over their faces. A sane person wouldn't last a minute in this place.
No matter how horrifying those monsters looked like, the devils that resided in Hell were already used to their monstrous appearances, so encountering others of their kind didn't faze them one bit. Eren was no exception to this.
But there was one devil that even most ancient beings of Hell feared. Eren–in his Attack Titan form–heard it approaching.
The sound of chainsaws.
All the devils in the vicinity put aside their differences for a brief moment. Eren, who was currently facing his 500th battle against the Darkness Devil stopped as well to see the source of the sound. The faces of that composed almost the entirety of the Darkness Devil's body started to scream in agony.
Eren widened his eyes. Was the mere sound of chainsaws enough to scare even a powerful being like the Darkness Devil?
The monster disappeared from sight, leaving Eren and a couple of devils on their own.
Nuclear Devil, Drug Devil, Angel Devil, and him, the Freedom Devil, remained.
The Attack Titan squinted as it tried to get a better view of the silhouette that presented in front of them. It was a black armored monstrosity, with spikes adorning all of its body. It had four arms. Its hands had long, highly spinning chainsaws. Its skewed head had a mechanical form that highly resembled that of a chainsaw, with the spinning blade standing out on its forehead.
The devils wasted no time and lunged towards the Chainsaw Devil. The Angel Devil and Drug Devil had no time to activate their abilities as they got pulverized by Chainsaw's rapid assaults. The Nuclear Devil tried to unleash one of its bombs, only to be caught by the jagged fangs of its opponents.
Blood splattered everywhere as the Nuclear Devil got mauled by the Chainsaw Devil. All of it. Eren could the Nuclear Devil's very essence disappear.
Now he understood why the devils in hell were terrified of Chainsaw. Its power was terrifying. It had the power to erase concepts by eating them! That means that if the Chainsaw Devil ate him… then the concept of freedom would not be possible.
Human individuality would cease to exist.
Eren made up his mind, the Chainsaw Devil itself is an existence that must be destroyed. He's a mortal enemy.
No matter how eldritch Hell looked like, no matter the dangers it faces, the Freedom Devil's maxim meant that he would keep moving forward and pulverize every enemy on his path.
Both devils roared and charged at each other, ready to die.
And what followed, was total darkness.
AN: For now, this will remain a one-shot. This is an idea that has been popping inside my mind lately, so depending how well this performs, I may decide to continue it.
