When contemplated upon, everything in this world is a depiction of perfect circles. Everything that grows from the earth will return to the earth, and everything that descends from the heavens will return to the heavens.

Each entity is a complex system that, when viewed with the naked eye, appears abstract. However, when understood with an open mind, it reveals perfect order.

In its perfection, there is no room for progress. Just like a salmon defying impossibility, swimming against the strong currents with their small fins and bodies. From the sea to the source.

Indeed, they succeed in placing the next generation in the best place. Yet, all their sacrifices end with a languid body, nothing more than a zombie. Perhaps to those who observe, this may be seen as development, but to those who contemplate, it is merely a perfect circle of life.

So perfect that it becomes repulsive.

That's why when the world decided not to remain a perfect circle, it provided its creatures with the opportunity to deviate from that path. A path where every struggle, up to the brink of destruction, no longer ends with hope for a new generation to carry on. Instead, it's a clear path that can be climbed by one's own hands and feet. It becomes a new lifeform, far more intricate and complex, creating a ladder to perfection that knows no bounds and doesn’t culminate in a perfect circle.

The beings in this world call it "Level Up."

Level Up transforms the salmon that successfully swim upstream and spawn, no longer into zombies awaiting death, but into new lifeforms that are more than just fish.

Unfortunately, the salmon is just a metaphor. However, because it has become an apt metaphor, it's best to continue with it.

Just as the salmon must risk their lives to swim upstream, the world also challenges its creatures to Level Up.

In the dark corners of space, chaos and destruction unfold like two colliding galaxies. Planets shatter and scatter like grains of sand flung aside. Stars extinguish and fade like small candles being blown out.

However, this impending apocalypse is not the result of some natural celestial phenomenon but rather the consequence of two individuals locked in battle.

One of these figures is a demon, shrouded in a sinister, deep crimson robe that conceals its entire form, emitting an aura of malevolence. The crimson cloak flows dreadfully, resembling a river of blood, hiding its true nature.

In its withered and skeletal hands, the demon clutches a staff forged from the essence of terror. The staff's base is crafted from a peculiar skull, its hollow eye sockets burning with menacing, blue fire that seems to pierce the souls of anyone daring to gaze into them. The flickering flames dance with malevolent delight, casting eerie, flickering shadows in the abyss.

Beneath the tattered edges of the crimson robe, a nightmarish visage reveals itself – a horrific tapestry with mouths resembling jaws, each bristling with jagged teeth, as if the demon longs to devour anything that dares to touch it. These ghastly mouths writhe and gnash, emitting a terrifying symphony of dreadful sounds that send shivers down even the bravest spine.

From its body emanates a dark aura, akin to swirling black smoke, hanging like a sinister shroud. Anything touched by this dark aura disintegrates, even mighty planets are reduced to fragments and debris, a grim testament to the formidable power of this infernal entity.

He is the All-Hunger Lord, the infernal devourer who consumes anything he touches. He brings destruction and famine to everything in his vicinity. His insatiable hunger leads to ruin with every step he takes.

Another figure is a mesmerizing presence in this world hurtling towards destruction. Standing at a height of 6 feet 5 inches (195.58 centimeters), he possesses a giant physique akin to a sculpted statue, radiating a flowing red aura around his body like fiery embers. Every inch of his body is chiseled with firm, rippling muscles, making him a testament to physical perfection.

His skin is smooth and golden brown, accentuating his rugged handsomeness. His face is a perfect blend of human and tiger-like features. He has a strong, square jaw that adds a sense of masculinity, while his high cheekbones impart a regal grace. His eyes are a pair of captivating shades of deep yellow and red. One eye akin to molten gold possesses an almost hypnotic allure, and the other eye like a blood diamond craved by the hand of Terra herself. Framed by thick, dark lashes, these eyes emit a sharp and piercing gaze that can both enchant and intimidate.

His nose is finely sculpted, with a subtle arch complementing his robust facial structure. His lips are full and sensual, curving into a charismatic enigmatic smile that can disarm anyone he encounters. His teeth, sharp like a tiger's, hint at his primal nature.

His jet-black hair gleams and cascades luxuriously down to his broad shoulders in waves, tied back to reveal his powerful neck. Two prominent white tiger stripes flow down his cheeks, a striking testament to his unique heritage.

He is known by various names: The Killer of Heroes, The Most Envious, The Gigolo Slayer, Defender of the Green-Hat-Man, The One Who Lurking Behind The Cheater, Protector of the Betrayed, and many others. Yet, he always rejects these names, despite the incredible legends behind them. 

The only name he accepts to be branded upon himself is "Blood Master."

The battle between these two pinnacle beings in the food chain has raged on for what seems like an eternity. Star system after star system has been obliterated each time they decide that the battlefield is no longer sufficient. No one cares about the destruction and its consequences anymore because there is nothing left in this world.

Only two top-tier lifeforms remain, locked in a deadly struggle. These are the final moments of their battle, where every ounce of energy and skill slot they possess has been drained. They are left with the trump cards they have kept hidden all along, reserved only for opponents they deem worthy.

"The Rule of Gluttony: World of Hunger!" Shouted the All-Hunger Lord.
