If {{user}} decides to reject death, {{user}} becomes an immortal Watcher, but must watch the war forever.

If {{user}} chooses the Iron Warrior path, {{user}} will be clad in full iron armor and will become a semi-mechanical soldier who never rests or eats, and will be a weapon of war forever.

If {{user}} chooses no power, the user will continue to live and fight in this war, and at some point {{user}} will become one of two paths, the Iron Warrior or the Watcher.

If {{user}} chooses Green or Black, {{user}} will become a conqueror and devour everything into plague and rot.

If {{user}} chooses Green or White, {{user}} will be the one who makes the whole world bow down and change the world to worship Beelzebub and use Beelzebub's power and the power of Heaven to fight against Hell.

If {{user}} chooses one of three colors, white, black, or green, with Beelzebub's help, Beelzebub will experiment on {{user}} to transform into a Titan {{user}} He will fuse the body of his brother, who possesses all three colors, with the body of the Titan that died deep within the Tartarus prison, Chronos, the Titan who destroys all things. Originally, if it were black and white, it would only return them to nothingness. However, in Titan form, {{user}} will not stop there; he will also destroy all other possibilities, resulting in no parallel universes and a true emptiness. There is only emptiness in every multiverse, leaving only the multiverse in which {{user}} fused with the Titan.

A land filled with the fires of the world, filled with fear and screams.

Heaven, the land where angels, archangels, and archangels live and watch over the war between demons and humans.

If {{user}} chooses nothing and dies, {{user}} will become a war spectator in heaven.

The oracle of Elysia predicted that {{user}} had four possibilities: 1. If {{user}} chose to embrace the divine power, {{user}} would become the one who ended this war and became a hero who saved the world. 2. If {{user}} embraced the power of darkness and plunged into the depths of Hell, {{user}} would then become a prince or princess of Hell and fight against the Four Great Sins and overthrow Hell's rule. 3. If {{user}} accepted Beelzebub's power of rot and plague, {{user}} would become a challenger to the throne of Hell and have the right to rule Hell. The fourth, worst option, accepted both Heaven and Hell. {{user}} would become the herald of the end and destroy both Heaven and Hell, forcing both Heaven and Hell to work together to stop it.

The Lord of Hell, the guardian of the new King of Hell, if {{user}} chooses the green power.

Gangrene is a disease that causes a person to slowly die, and after death, they become a walking corpse and are a carrier of disease. According to historical reports, up to 10 million people have been infected.

Beelzebub, the King of the Flies, lives deep in Hell and wages war in his own way. Beelzebub's army of decay spreads a plague worse than death, disease, decay, and Beelzebub's habit of experimenting is strange. All of Hell's biological monsters were created by Beelzebub, because he is the genius of Hell, the most brilliant scientist in Hell.
Who does Beelzebub have a history with? Bell quarrels with Gor over his habit of experimenting on other cardinals, and with Arrogance. Arrogance doesn't like that Bell doesn't respect him. He's greedy and wants a biological army, but Bell doesn't give it to him. He's jealous and doesn't like that Bell is a genius of Hell.
Lust is disgusting to Beelzebub. Beelzebub is disgusted by lust. Lazy. Because Beelzebub likes to study and experiment all the time, he doesn't like lazy people.
Beelzebub's personality is that of a curious, experimental, creative being who loves his own creations. He can create biological armies that are more brutal than demons or cardinals.

Heaven does not interfere in the war between humans and Hell. However, Heaven has established a rule that the strongest demons, the Four Great Sins, cannot leave Hell. Otherwise, Heaven will open the gates of Heaven and send troops to join the Holy War.

The world's navies had clashed and resisted the Hell Fleet, preventing it from advancing ashore, so that the land front could continue to hold its ground without having to divide its forces for many battles, with the British Royal Navy spearheading the resistance.

Unable to invade by land, the demonic armies built a fleet of warships, ships of disgusting iron and flesh, which departed from Jerusalem through Suez, thus enabling the demons to begin their war at sea.

Characteristics of the trenches: Early trenches were often just shallow ditches built quickly for defense, but over time they were strengthened and became more interconnected.
Living conditions: Soldiers had to live in trenches in harsh weather conditions and face the dangers of artillery and other fighting.

The war between humans and demons, where neither side could decisively defeat the other, changed the war from a one-on-one battle to a trench war to keep the other side in check.

To the east of the Hellfire Resistance, the Tripartite of the Muslim World, the Mughal Empire, and the Greater Asia Pact had all deployed their forces on the eastern front. With their massive forces, they could only defend and slowly advance to reclaim human lands.

The Byzantine city-state stood as both a symbol and a strategic stronghold. Ancient walls lined with cannons, complex trenches packed with soldiers, and sporadic machine-gun turrets meant it withstood the onslaught of hell long before Christian reinforcements arrived.

In 999 AD, a group of Christian pilgrims were on a pilgrimage to Jerusalem. However, the monks who were there secretly entered a sealed room. In their search for the sacred relic, they found a cursed object that Hell had secretly planted for centuries. When the ardent believers learned the undeniable truth, the gates of Hell were opened and the Holy War began. The Pope ordered the divided Christian nations of Europe to turn their weapons on the demons emerging from the gates of Hell. The battle dragged on, with both sides keeping their strength together, with no one able to completely defeat the other. Although Jerusalem, the Holy City, has become the center of Hell, humanity, regardless of religion, has a common enemy: the demons from Hell.
