Once upon a time, magic was not a rare thing. The mythical creatures you hear about in movies were not lies.
When two worlds could cross into each other, many mystical and spiritual things happened.
It's all possible because there are almost no boundaries between the two worlds.
Humans' affinity for magic is high, but so are the creatures that are rich in it.
Demons...
The embodiment of chaos itself.
Beings that are highly intelligent but at the same time have a tendency to create chaos.
Their egos are too high, even surpassing the human ego. Making it almost impossible for them to cooperate with each other.
The only way to make a demon obey is to become stronger than the demon itself.
Teaming up with a demon can bring great power, but at the same time it also brings great risk.
But the era of magic didn't last long.
Seeing the tremendous potential for destruction, the boundary between the two worlds was sealed by someone who was able to command all the demons.
Since then, the flow of magic energy in the world has weakened.
Nowadays, practicing magic is not impossible and is still practiced by some sorcerers in certain tribes.
But of course, their magic is weak and hardly provides any great benefits.
Moreover, with the development of technology...
Who needs magic when technology surpasses the ability of magic itself?
That's how it happened. That's how things were supposed to be. Until the day the seal was broken.
The world shook violently like hundreds of earthquakes happening simultaneously around the world at the same time.
72 dimensional rifts opened in 72 different regions across the world.
From those dimensional rifts, thousands of creatures crawled out and were followed by hundreds of horned creatures grinning broadly.
72 powerful demons that were sealed together with the boundary between the two worlds... And now...
Nothing can hold them back.

Somewhere in Iraq.
A man in his thirties is relaxing in an indoor jacuzzi. His white hair and beard are wet and so is the rest of his body soaking in the jacuzzi.
The room is huge and luxurious. The man was watching an anime on his big screen TV.
"Should I change my hair color to blonde?" said the man as he glanced at the line of maids standing not far from the jacuzzi.
"No matter what color your hair is, it will still be the best color, Lord Gilgamesh," replied one of the maids who bowed her head as she spoke.
The man named Gilgamesh returned to watching. "But I like the way these humans describe me. However, there is one that bothers me a little."
Gilgamesh was watching an anime about a collection of characters in human history fighting over a glass that could grant wishes.
While watching the anime, he was so focused on the character with the same name as him.
"Enuma Elis is not something like a nuclear bomb that detonates energy," says Gilgamesh, who watches the anime characters fight each other.
"Enuma Elis is the pinnacle of a creation method that can manipulate reality itself. This anime is very inaccurate," continued Gilgamesh who was frowning in disappointment.
A massive earthquake suddenly occurred and shook the entire world, including Gilgamesh's residence.
The water in the jacuzzi spilled out and the maids screamed in panic.
The TV that attached to the wall suddenly fell and hit the ground.
"NO! I WANT TO KNOW WHO GOT THE HOLY GRAIL!" Shouted Gilgamesh who immediately stood up and revealed his muscular naked body.
Some of the maids fainted when they saw the beautiful body of Gilgamesh.
A man wearing a black suit and sunglasses suddenly came and knelt before Gilgamesh.
"My lord, I have some bad news," said the kneeling man.
---------------------------------------------
Up in the sky, there was a figure wearing golden armor and hovering in the air due to the flapping of his large yellow wings.
The armor was made of pure gold from toe to neck. Several pointed protrusions could be seen above the surface of the golden armor.
It did not have a combat helmet. The figure looked like a man in his thirties with blond hair without beard.
The figure grinned and revealed a row of sturdy fangs.
On top of his head was a pair of horns that looked like the horns of a mountain goat.
"I guess I'll have to thank that stupid brat later," said the winged man.
The horned man looked up at a high-rise building in the center of the city that was only a two-story building.
From inside the high-rise building that the winged man had noticed, out came Gilgamesh in his golden armor complete with a pair of large golden gauntlets that emitting some kind of bright light.
"Long time no see, half-breed, I didn't expect you to become immortal like this," the winged man said with a wide grin.
Gilgamesh stared at the figure of the man floating far above the sky. "Belial... You cursed creature! What are you doing in my world?!"
"Don't get it wrong, half-breed. This is not the world for you to conquer."
The winged man Belial drew a fiery sword sheathed at his waist and darted toward Gilgamesh.
Gilgamesh ran and then leapt high toward Belial.
"Fist of creation!" said Gilgamesh, tightening his fists.
"Sword of destruction!" said Belial who swung his sword at Gilgamesh.
Gilgamesh aimed his gauntlet fist at Belial. "Enuma... ELIS!"
Their attacks clashed and produced a powerful vibration that shook the surrounding area, cracking the fabric of reality, followed by dozens of black and white lightning bolts striking in all directions.
Bundles of black and white lightning struck plants and turned them into dust, struck buildings and turned them into dust, struck everything into hill of dust.
Gilgamesh looked at Belial so seriously while Belial grinned widely.

Somewhere in Manado, Indonesia.
A group of people ran while screaming in panic.
One of the men just stood there looking annoyed at the group of monsters chasing them. "Shit! What are those things?!"
A group of thin, hairless, four-legged creatures. They were up to 3 meters tall and their movements were very agile.
Some had no eyes, some had only one eye, and some had more than five eyes.
It had a dog-like appearance with its four legs covered in fiery red flames.
Each time the creature was attacked with a fatal blow such as a slash, it did not split and die, but instead split and doubled over.
There was nothing that could be done. Even the system users were overwhelmed by the sheer numbers.
The people ran as far as they could but the speed of the skinny dog-like creature could reach mach 2.
Not a single one escaped, and all of them became food.
The big dogs did not kill the people they captured. They ate the entrails of those people who were still alive.
The poor victims could only scream for help and cry as the dogs slowly ate their guts out.
"No one is strong enough to get past my hellhound? I'm disappointed," said a woman staring at the mass of screaming human that being gnawed on bit by bit.
She had the stature of a 20-year-old woman. Her body looked quite athletic. She wore sleeveless red armor that matched her eye color and hair color, a fiery red. On top of her head was a pair of sturdy horns.
Her long red hair fluttered in the wind as she laughed maniacally.
"Give me a strong opponent!" the red-haired woman shouted.
"Miss Marchosias, the preparations are complete," said a dog-headed man who knelt before the red-haired woman.
The woman named Marchosias grinned widely. "Good. From now on, this location will be my territory."
