"Look at them all, nothing but children playing in the dirt," spoke Amon, the great demon hero of Hell.
He stands atop a hill, overlooking a ravenous group of demons who're busying themselves by slaughtering the damned souls of the humans who were sent to Hell. Amon watches as the demons began tearing the humans apart, limb from limb. Blood and guts start spewing all over the desert ground; then other demons soon began to consume the humans too.
During this assault, the humans try their best to escape, but to no avail as more demons began to appear from out of nowhere and surround the remaining humans. They then begin to jump on them and the screams of the humans and demons alike started echoing from the top of the hill where Amon was still watching from.
But from the loud screaming and yelling from below, Amon soon hears the flapping of wings from behind him. He turns to see a demon harpy landing gracefully on the rough, sharp rocks of the hill. Her name is Sirène, and she is regarded for being the most beautiful demon of all Hell. Though she does look like an angel, she holds such immense power that no angel can hope to hold themselves. But not enough power compared to Amon, who doesn't seem that much surprised to see her.
"Hello Sirène," said Amon, "what brings you here?"
"I only wish to know why you're here instead of taking part of the massacre," replied Sirène.
"It would only be a waste of time for someone like me."
"Oh come now, even a strong demon like you need a little fun once in a while."
"Then where's the fun in killing things that won't even fight back. It makes things way too easy, and takes away the challenge of destroying those with greater strength than yours."
"Is something the matter," Sirène asks as she looks at Amon, thinking that there's something wrong with him.
"Why are wasting our time down here? We shouldn't even be down here still! We should be up there, in the human world, acting like conquerors to them. But instead, we willowing to these miscreants of souls and toying with them. They can't truly die like prey; once they perish, they'll just pop up out of nowhere, and the demons can continue their fun. It's nothing but an endless cycle."
Sirène looks at Amon with deep concern. She then places her hand on his shoulder.
"Listen my love, you mustn't think of this place as a prison. You are right to preserve your strength for when such an opponent appears. But for now, you should relax, and be at peace with yourself."
Amon looks at Sirène with a stern look on his face, and he removes her hand from his shoulder.
"Why must you so weak-minded? Are you really that stupid," said Amon.
Sirène was taken aback by this comment; she took a step from Amon.
"What do you mean by that," asked Sirène.
"Why must you always pester me with that talk of holding back my power? I'm not called the strongest demon for nothing; I've destroyed countless angels during the first Armageddon. I've unleashed so much of my abilities during the war that nothing stood in my way. I was proud of being hailed as the hero for all demons. I WAS A CHAMPION AMONG GODS!"
Sirène looks at Amon with awe as he delivers this ultimatum. She can only think about what all this means to him. She soon realizes the answer with what came next.
"But now, after so long, I felt something inside myself. Something I've never felt before."
"What? What did you feel," asked Sirène.
"I felt… weak," replied Amon.
"What?" Sirène was shocked over this statement.
"I felt my power slowly deteriorating from my body. Everytime I try to keep myself strong, I only find it gone the next day."
"But, that's sounds impossible. A demon never loses their power when they're Hellbound. What do you suppose is wrong?"
"I don't know, but I intend to find out myself before it gets any worse."
And with that, Amon spread his wings and flew off the ground at a very high rate. Sirène was a bit blown back from the draft, but she stood her ground and sees Amon above in the air. He flies away to parts unknown at supersonic speed, leaving Sirène to ponder at what's happening with him. How come his powers could be depleting from his body and what could be something that's draining him to be weak? All these questions, and more, were filling Sirène's head until she began to grown, but she soon stops as she's visited by an old friend.
"Hello Sirène," spoke Kaim, a large rhino-like creature with two spikes protruding forward from its shoulders.
Sirène turns to see him before her, with the same stern look on his face.
"Kaim, it's been a while," said Sirène.
"Is something bothering you."
"It's what Amon said to me, that he's losing his strength from something."
"That's a first I've heard."
"What do you mean?"
"It's unusual for a demon to be growing weak while still being Hell. Perhaps it is something wrong with him instead."
Sirène looked surprise at this assumption by Kaim. She thinks it over; Amon was acting strangely before this moment. But the one question that ponders in her mind is what's causing this on Amon, and why this is only happening to him and nobody else. She could only think on one thing about this situation, but then, something happens immediately, breaking her concentration.
Several of the demons below started acting weird and strange. Then, they started to disappear slowly. Sirène looks upon this with great shock, and turns to Kaim in confusion.
"Kaim, what is happening," asked Sirène.
"It appears that they're sensing the blood and filth of human souls on Earth. And they're preparing to embrace their new bodies," answered Kaim.
"You mean… they're possessing humans? This is a first I've heard in a long time."
Just then, out of nowhere, Amon spoke from behind.
"Sirène, I believe I found the solution."
Sirène turns to see Amon, smiling?
"Amon, what do you mean?"
"You can sense it, right? The vile stench of lust and greed in the human soul can revitalize me of my power. This is perfect!"
And with that, without hearing a reply from Sirène, Amon disappears before her. Sirène could only look on at the empty field of dead corpses. She then turns to Kaim, who hasn't disappeared yet.
"Are you not going," asked Sirène.
"I would, but something about this doesn't feel right to me," said Kaim.
"What's that supposed to mean?"
"I mean… that this display for the demons seems staged to attract us. Almost for a purpose."
Sirène looked at Kaim with deep surprise, and so much confusion.
"That doesn't make sense. How could the humans stage a display of such human disgust? Unless…"
"Unless, there's someone out there who seeks to destroy us all."
And with that, Sirène looks up at the sky of Hell, thinking for Amon's safety, but unbeknown of her, Amon has already been faced with a challenge that he could never face. The pure heart of humanity, in the form of a man named Fudo Akira.
