1 Prologue: Land of Steel

Earth has died and almost all of the inhabitants ceased to exist, except for Humans. The Human race manage to survive in the Apocalyptic like, Dead Planet by modifying themselves into High Humans, A new Species that has high physical, Mental and Magical capabilities than a normal human body, they also created the A-rays which is a human that has the genes of an extinct creatures on earth to preserve its value but it caused an uproar between the A-rays and High humans. The A-rays waged war against the High Human and the war begun which is called the Great War of Steel. The war is mostly balanced, no other forces are winning nor losing until the A-rays was taken under the wings of the Sisters, Angel-Like Creatures that has a NORMAL power output that rivals a Nuclear Bomb. The war would have won by the A-rays if not for the humans creating their own soldiers called Ether Liners, they are soldiers that has a unique ability called Knight Arms, a kind of skill that will form a weapon that uses the surrounding Ether or Grain to manifest which depends on the character of the user. It is said that these Ether Liner are powerful enough to level an entire city and there's thousands of them. The war begun to remain at a stalemate until They Arrived.

The Aristotles or Ultimate Ones arrived to the dead planet to eradicate all life that remained to exist in the planet, which is in fact wished by Gaia The Will of the Planet before it died. The Ultimate Ones are the strongest creature on each planet of the Solar System with the leader being "The Cross", Ultimate One of Saturn. Every Ultimate Ones has the power to Destroy an entire civilization alone. They are very powerful that only a Handful of Ether Liners can fight them and the Sisters are among of the beings capable of fighting them. With the arrival of this Godlike alien beings the war that is endlessly going is halted and the 2 races formed a truce to help each other to survive against the new threat.

After the arrival of these creatures some have been neutralized but some has also destroyed part of the world. Type-Saturn Destroyed majority of North America and flee while Type-Jupiter got Destroyed by Ado Edem, an Ether Liner that has a Knight Arms that grows in size according to the size of the enemy, since Type-Jupiter is 13km Tall Energy-Like Humanoid that has a Miniature Sun on its Chest. Ado Edem's Sword "Slash Emperor" grow to about 6km and swung it, Killing the Type in One Hit but this caused the core to overload and engulfed the entirety of Europe in flames, burning all of it to ashes… Ado is the only one who Survived. Other Types like Type-Venus got shot by Gun God using its Rifle "Black Barrel" while Type-Mercury and Type-Neptune is Hibernating in unknown place on earth Type-Uranus is Wrecking Havoc in Asia While the Type-Pluto is killed by the Sisters. The Sisters after killing Type-Pluto used its blood to block the other Types from Entering and it succeeded but this is still not the time to celebrate since there may be a chance that they can penetrate it and once again attack the land.

Every News about the Types, everyone in the sanctuary shivers from its sheer size alone, but they still have hope since many people are fighting these creatures and bring peace to the world, the humans and A-rays has accepted to become allies and Plan to lived together in this dead world.
