The World (世界, Sekai?) is used to refer to either the Earth, Gaia, or the collective unconsciousness of mankind, Alayashiki. There also exist the Reverse Side of the World and the Outside of the World.

The Ultimate Ones are vessels upon which the planet's will is manifested, and rather than being part of the Counter Force, they are essentially the planets themselves. Unlike most other celestial bodies in the Solar System, there is no clear Ultimate One for Earth. The creature closest to being the Ultimate One of Earth is Archetype Earth.

Another definition of "world" refers to a particular location or environment, much like its real-world definition. Differing from the concept of the Earth, a world can exist in a variety of shapes, such as "the world of the humans", the "Reverse Side of the World", "mental world", or "underworld."[1][2] This article will deal with the former definition of "world".


The Earth was initially formed from molten magma and gas. Life did not emerge until the inhospitable planet cooled and settled. The infernal landscape of the Earth before genesis has become part of the genetic memories of all creatures on Earth, and humans drew from this imagery when they created the concept of Hell.

Age of Gods[]

The time period beginning with the genesis of the Earth until the beginning of the Common Era around 0 AD is referred to as the Age of Gods (神代, Jindai?), during which the world followed laws based not on physics but on Mystery. This period is marked by a greater proliferation of Phantasmal Species and greater interaction between gods and mortals. This is the age of heroes and mythology, when rules of mankind and the laws of the world were different right down to the very fundamental physics of reality itself, but this period ended many years ago. Even Magecraft itself is described as being closer to Magic in this era and Caster's abilities reinforce this concept. The currently-revealed Second Age of Gods eventually transitioned into the Age of Man due to three major events.



Originally, gods existed in physical form as manifestations of nature itself, and ruled the Earth and its civilizations. The Deterioration began with the invasion of Sefar in 12,000 BC. After Sefar destroyed the majority of the Earth and a massive number of gods, she was finally beaten back by a Holy Sword forged in the core of the planet; however, due to the damage done by Sefar, the influence and power of the gods declined whereas those of humanity grew. The gods slowly began to lose their physical forms and eventually could only walk on the Earth by possessing compatible humans.


Realizing that if the weakening of the gods were to continue, the Age of Gods itself would end, the gods of Mesopotamia created Gilgamesh around 2,600 BC as the keystone to connect the gods and humans. However, Gilgamesh unexpectedly rebelled against the gods and encouraged the complete separation of the gods and the humans. Due to this, the decline of the gods was accelerated and the gods lost their powers and became Divine Spirits, forced to exist likely in the Reverse Side of the World , only able to observe the Earth without directly interfering. Later, the demise of Solomon, the King of Magic, accelerated the decline of Mystery.


In 700 BC, there was a certain Trigger that caused the end of the Age of Gods and the beginning of the next age. Further details are unknown.[3]

Age of Fairies[]

Not much is known about the Age of Fairies (妖精の時代, Yōsei no Jidai?), but the Age of Fairies has ended.[4][5]

Age of Man[]

Around 0 AD, the Age of Gods ended entirely and the population of humanity grew explosively. Because the Earth obeys the law of the most prosperous species on its surface, the rules of the world were completely changed from one that mostly obeyed Mystery to one that mostly obeyed physics. The Phantasmal Species ceded the Earth's surface to humans and moved to the Reverse Side of the World, where Mystery still thrives.

The current age is identified as the Age of Man (人間の時代, Ningen no Jidai?), where Mysteries such as magecraft are dwindling in favor of science. The Five Magics were born in this age.

Counter Force[]

Main article: Counter Force


The future of the planet is undetermined, with many possible outcomes available depending on the conditions present in the parallel worlds. The Mana Depletion of the world of Fate/EXTRA is caused by the Aylesbury Valesti producing a pole shift that began the depletion of mana. The world of Tsuki no Sango experienced a similar pole shift and the decline of the human race rather than magecraft. The world of Notes died entirely, and humanity still occupied its corpse. Gilgamesh saw a future where, following the wishes of the Çatalhöyük,[6] humanity outgrows the planet and reaches for the light millions of lightyears away.[7] Merlin saw a similar future, a new Age following the Age of Man called the Age of the Will (意思の時代, Ishi no jidai?), where humanity will live among the stars and those unable to live without a flesh and blood body will be left behind.[4] It is also Archetype Earth's wish for humans led by their forward way of thinking.[8] Flat Escardos also made the cryptic declaration that all human lives are valuable "for jumping clear of the Earth", with his eyes somehow seeing a far-off destination, probably the same as Merlin and Gilgamesh.[9]

One possible future of the world is the Overcount 1999 (オーバーカウント1999?) phenomenon, the beginning of the decline of humanity. With the Earth's resources dying, the ability to live on the planet is gradually lost. The nucleus of the Earth, what can be said to be its soul, is hurt.[10] The cause is unknown, possibly the Aylesbury Valesti ritual, and the phenomenon is associated with the Land of Steel.


The world of Fate/EXTRA shares the same events as that of Fate/stay night up until a certain point until a "certain major incident" in the 1970s that caused the world's mana to start drying up causes it to split off into its own separate universe. As of the 2030s, the world's mana was completely gone. The cause of the phenomenon, the stagnation of human history, is said to be ■■■■■■.[11]

Fate/Grand Order[]

The future was previously established so that humans would prosper for the next century at the minimum, but that future has become unobservable in 2015 due to the appearance of the spacetime anomaly designated Singularity F. Using Grand Orders, the Chaldea Security Organization seeks to correct the Singularities and undo the Incineration of Human Order.

One year after the Chaldea Security Organization stopped the Incineration of Human Order and saved the planet, the world was once again attacked, this time by an Alien God claiming to be from outer space and with the help of the Crypters, the former members of Chaldea's elite Team A. On December 31, 2017, the seven Fantasy Trees fell to the surface of the earth, creating across the world seven Lostbelts, alternate histories that had been pruned from Proper Human History. This act erased the surface Texture of the planet, creating a Wiped Blank Earth (白紙化地球?).[12] The branches of the Fantasy Trees became a membrane that covered the Earth, blocking the stars from view, and the planet is lifeless save from some rare areas that survived the blanking, including Area 51.[13]

Fate/kaleid liner PRISMA☆ILLYA[]

The parallel world of the Ainsworth family in Fate/kaleid liner PRISMA☆ILLYA has experienced a shift in the axis of the world and the start of the depletion of its magical energy through a cause unknown to humans. This has brought on changes in the environment like abnormal weather and changes to the coastlines, such as Japan experiencing cold weather and snow during the summer. Plant life has declined, causing a decline in the animal life that feeds off the plants, and it has reached the human population as well. The process for the depletion of energy will take several hundred years, and the humans will not last more than ten generations before the world's destruction.

While science will allow humans to prevail in the short term even with the miracles of the world vanishing, the rules of the world being rewritten make it a surety that humans will perish. "Dry spots" are beginning to appear around the world in places where the energy has been completely exhausted, and an unknown particle unlike magical energy is spreading through those areas. Acting as a poison to wipe out everything alive under the current rules of the planet, the current inhabitants cannot exist in the new world. The Ainsworths plan to use the Holy Grail, Miyu Edelfelt, to use the remaining energy on the planet to make humans into beings that can survive in a new world, similar to the A-Rays and Liners of Notes.


Main article: "After" the Holy Grail War

The world of Fate/Requiem takes place in 2025, and 14 years beforehand was devastated by many Holy Grail Wars all occurring at once, also known as World War III. It is said that not a single nation was left unharmed by the fighting. Countless drones were deployed during the war to the point that drones have become a horrible thing not to be talked about by the people who lived through it. In addition to the devastation on the surface, much of the world's sea life was also wiped out in the crossfire.

The conflict was resolved by Chitose Manazuru and her Servant Lucius Longinus, who obtained the Holy Grail. The Holy Grail created Mosaic City where survivors gathered, though much of the world beyond the city's borders is a wasteland and water levels have risen dramatically. Everybody who survived the war were given Grails in their hearts, and the new generations born after had Grails within them from birth. Everybody has a Servant bound to them by fate, as well as Command Spells. Humans can no longer die of sickness or of old age, though are still able to be murdered. People can even use Command Spells to change the physical age of their bodies. As Servants have become commonplace and are living in Mosaic City alongside living people, Mystery is largely exposed and magecraft is common knowledge, though like in the world before not everybody has the capacity to be a mage.


Main article: Land of Steel

Land of Steel (鋼の大地, Hagane no Daichi?, [over count 1999]) is the name of the world in the time of Notes. It is not the official name, but a nickname passed down by those who live on the dead planet. The land is no longer able to support life due to the continents being mostly cracked wastelands unable to properly allow for the growth of food, and the atmosphere, covered with gray and sepia clouds, is no longer suitable for animals. Despite these conditions, humanity has lived on by utilizing their developed civic technology.[14] Due to their survival, the planet, not wishing to have beings live on past itself, made a final wish to the other planets to completely wipe out humanity. They responded by sending the Ultimate Ones, which ravage the Land of Steel in order to fulfill their purpose.

Cloud Sky.

Blood Sky.

The world is filled with Grain (ジン, Jin?, "Gin", [grain "Ether"]) harmful and unpredictable space dust particles generated from the dead planet.[15] It is lethal to regular humans, who require special medication and machinery to process it, but it has had beneficial effects for A-Rays and Liners. The energy transfer rate of the Grain scattered in atmosphere is incredibly high, and it resulted in a new level of warfare that was never before possible due to the A-Rays and Knight Arms making weapons of the old age useless. The Cloud Sky (空が、昏い, Sora ga, Kurai?, The Sky, it's Dark), said to be a barrier created by the Six Sisters to repel the Ultimate Ones, is a thick layer of clouds that has hidden the sky since the Great War.[16] It covers the Blood Sky (空が、赤い, Sora ga, Akai?, The Sky, it's Red), which is completely red rather than blue. This resulted not from pollution, but from the blood of Type Pluto after its destruction in the atmosphere completely covering the sky.[17]

The main inhabitants after the death of the world were the A-rays and the surviving human race. They fought against each other in a conflict called The Great War (大戦, Taisen?, [Babel's Tale]) where the A-Rays, under the Six Sisters, wished to rule the world, while the humans fought to survive.[18] Humanity, on the verge of defeat, eventually developed Liners and the Knights to help in their battles, but this did nothing more than further destroy the already dead planet. The war had no victor due to the sudden appearance of the Ultimate Ones, having arrived to fulfill their goal of wiping out all living beings. Both sides were nearly wiped out, and they started working together to fight against their combined threats. The Ultimate Ones slowed their activity after the end of the war, but still continue to slowly wipe out the remaining humans. Type Jupiter, Type Venus, and Type Saturn have all been destroyed, which has led for a call to the planets to initiate a final battle with the humans.

Tsuki no Sango[]

The world of Tsuki no Sango takes place in approximately the year 3000, when humankind arrived at the peak of its civilization, but is losing its will to keep living.

The Lunar Immigration Plan was one of the strategies they came up with to deal with an overpopulation crisis. It succeeded, but then a great disaster struck: humanity lost its "heart's fire". The desire for growing, expanding or excitement for invention. With this, the Moon's humans decided to abandon the Earth's humans. After 50 years of that tragedy, the Earth and Moon sealed their doors to each other, becoming entirely independent of each other.

Apparently, some decades later the light of the Moon disappeared and at the same time, humanity’s population on Earth also dramatically declined. The motive was simple: no one felt like propagating the species anymore. After these fifty years, humanity was to be extinct, if not for a group that still "keep trying".

Tsuki no Sango is "a degenerated world where magecraft yet lingers". Like the world of Notes, it is a Land of Steel type of world.[19] Like the world of EXTRA, it also experienced a pole shift.

    Name: BB
    Master: None
    Noble Phantasm: Cursed Cutting Crater (C. C. C.)
    Keyword: Advanced level AI, khakkhara of domination
    Strength: ★, Endurance: ★, Agility: ★, Magic: ★, Luck: ★

    Cursed Cutting Crater (C. C. C.)
    An attack on the world by BB in control of the Moon Cell.
    Also called the spirit particle imaginary pit.
    A world purge by means of event rewriting, making maximum use of the EX skill “Potnia Theron” BB had acquired.
    The goddess who is the mother of the earth goddesses who created the earth is, in other words, the “root” that created all creation.
    This Noble Phantasm is an anti-world Noble Phantasm that outputs information like an ultra-precise 3d printer and crushes the present world with the world desired by the user.
    The space eroded by BB becomes imaginary space and a curse that consumes reality. CCC as the name suggests is a cursed pit that bores out reality.
    In addition to scattering all objects inside on an atomic level and reconstructing them, it is capable of writing over and rewriting information of fields such as luck and coincidence.
    While theoretical, it is also thought possible to distort the time axis by interfering with gravity fields and rewrite the law of cause and effect.
    When used in combat, BB’s familiars, the shapeshifters engulf the target, and after turning into a sphere, is wiped out of existence along with the target and the dimension with it.
    Normally, a structure in which value can be shared cannot be constructed in the far side of the world, which is imaginary space. What established BB’s internal world as the Sakura labyrinth was the power of this Noble Phantasm.

    Advanced Level AI
    An artificial intelligence configured according to their program. In this age, they are treated as things that "function as programs," but "do not exist as actual beings." In other words, things that "are" right in front of your eyes but "are not." They are merely a mechanisms for the sake of allowing human lives to progress smoothly.
    As it is the same for the SE.RA.PH, they are virtual lifeforms that are created along with the commencement of the Holy Grail War and disposed along with its completion.
    Within the SE.RA.PH. the humanoid virtual lifeforms are: the NPCs that perform only one task, AIs who have been granted the capability for self-judgement, and the advanced level AIs who have been trusted with the capability for self-judgement ad the management of a section.
    Advanced level AIs are things created to efficiently promote the Moon Cell's primary objective of "human observation." As they are perfect reproductions of humans, they have been programmed with a at least a soul, but while the soul "is there," it is contents are still colorless.
    The virtual lifeforms that the SE.RA.PH creates are reset with the round of the Holy Grail War. The NPCs and AIs return to zero, while advanced level AIs retain just their persona and their memories are reset--made to pretend that they never existed.
    When the Holy Grail War is over, the one who is left alive is the Master standing at the summit. This is a fact that applies not just to the Masters but is also held in common by the virtual lifeforms that the SE.RA.PH created.
    It appears that BB is an advanced level AI entrusted with managing the health of the Masters, the same as Sakura. However, as she is now rampaging for reasons unknown, the methods she uses to "manage the Masters" have become extreme.

    Khakkhara of Domination
    The teacher's pointer that BB carries. A device that allows her to use her use her authority as an advanced level AI to its fullest. Although restricted to the far side of the moon, this allows BB to revise the game rules (spirit particle laws within the SE.RA.PH).
    The ten crowns of domination worn by the Beast of Babylon converted into a teacher's cane. This is a male principle responding to a female principle; it's true nature is a phallus (an erect rod).
    The symbol of the king of the world who was granted power and authority by a great dragon and, during a period of 42 months, spat as many insolent words as they desired and had received the right to desecrate all things.
    The beast's heads were the seven hills of the Roman Empire... Capitolium, Palatium, Aventinus, Esquilinus, Caelius, Quirinalis, Viminalis. In other words, they symbolized the Roman Empire itself, and the ten horns were symbols of the emperors... Augustus, Tiberius, Caligula, Claudius, Nero, Vespasianus, Titus, Galba, Otho, Vitellius.

    Golden Grail [EX]
    The golden grail that BB possesses. The Holy Grail. The Holy Grail that grants its owner's impudent and selfish desires.
    The grail that the great enchantress who appears in The Revelation of St. John the Divine holds. Though it's a counterfeit Holy Grail, it's because that it's a counterfeit Holy Grail that it's become a "genuine" Holy Grail that grants the desires of humans without paying heed to right or wrong.
    To the Christians of those days, who considered honorable poverty a virtue, this grail, which was formed as a symbol of treasures such as gold, is no doubt the meaning of corrupt wealth, greed, and the vanity that leads one to adorn oneself.
    As the grail held by the great enchantress of Babylon who personifies the Roman Empire, it clearly symbolizes worldly riches, which is the opposite of Christ's words "Do not pile up the wealth of the earth."
    "I saw a single woman astride a red beast. This beast, whose entire body was full of numerous blasphemous names, had seven heads and ten horns."
    This is the description of the beast of destruction that appeared in the Holy City and the woman who was straddling this beast, according to the book of Revelation. A large beast with seven heads like a hydra came from the sea and disembarked toward the Holy City. This beast and woman, while two, are as one, and it is impossible to think of them separately.
    As this woman is said to give birth to all evil, those who are imprudent or greedy cannot resist her allure and become corrupted by that grail.
    This is a digression, but it is said that the red Saber who calls herself the emperor was regarded the same as this beast and antagonized after her death by the Christians.

    Self-Modification [EX]
    A skill that allows one to restructure oneself. AIs created by the Moon Cell are under an absolute rule, "Improving one's functionality is not allowed."
    However, BB, who had escaped that yoke due to her breaking down, began to expand her own functions. In order to boost her calculating power, she had that black noise prey on and dismantle NPCs, AIs, and finally, Servants, then used them as her own memory.
    Though they are appendix-like additions that won't spare her from the fate of collapsing on her own, BB has changed into a hyper level AI who holds an enormous amount of capacity. That condition resembles cities on reclaimed land that continue to build while submerging or Frankenstein's monster.

    Potnia Theron [EX]
    Potnia Theron (Conception of All Animals).
    The authority of the goddesses whom BB compiled and absorbed from the abyss of the mooncell.
    What it is is the embodiment of the power of creation possessed by the mother goddesses, originating from a forgotten goddess approximately 8000 years ago (the goddess of Çatalhöyük), and branching to Tiamat and Cybele, Ishtar, Inanna, Athena, Astarte, Gaia, Hera, Artemis, Aphrodite, Demeter, Athena, etc.
    Many are imaged with mural crowns. This is because many of the goddesses were also the guardian deities of cities.
    The symbols of this authority are the holes opening in the earth and the sky (caves and the moon), the whirlpools and typhoons of the sea, the craters of volcanos, and so on, and from these, evils bringing forth all manners of death are birthed.
    But once these evils have finished spreading death, they leave the promise of good harvest and fertility. This authority is none other than the power of bringing death as well as giving life.
    The earth mother is a guardian deity revered by the people and their protector, and at the same time she is the sacrifice that feeds them with the crops born from her body and the beasts of the fields and the forests.
    The earth mother feeds man with her blood and flesh, kills man over time and absorbs him as nutrition, and once again feeds man with her replenished blood and flesh.
    This process is the circle of the food chain, and the cycle of life and death can be said to be the true nature of the earth mother. With this authority, most of the goddesses gave birth to countless monsters and giants and posed a threat to the gods and man, or they gave birth to heroes and became protectors of man.
    Tiamat and Gaia are examples of those who became threats, and Hera is an example of a mother of heroes.
    Those born on this earth cannot defy the authority of the earth mother, as that would mean rebelling against the system of life itself.
    However, it is when they have left this earth to go into outer space and ended the infantile stage of intelligent lifeforms that they should no longer be bound to this authority..
    The wish of Çatalhöyük is the coming of that day.

    Spirit Particle Imaginary Trap
    Cursed Cutting Crater (Spirit Particle Imaginary Trap)
    The official name of this stage.
    The fact that BB had reached the Moon Cell core established this “place”, formerly imaginary space for storing malicious information, as real space in the present, past, and future. It was reconstructed at her hands as a “far side of the moon” where even Masters can exist.
    BB attaining the power of the primordial goddess succeeded in quantifying the “nothingness” before the birth of life. She transformed into a master of imaginary space where time and space are indefinite.
    While the Moon Cell can’t be hacked however much time is spent, BB was able to take control of it by placing herself in “unlimited time”.

    02 The remnants of peaceful days
    After the constraints to her free will were removed by Kiara, she was unable to control her status abnormality and went into overload.
    As NPCs can only do routine work, they ignored Sakura while she was crashing down as being “non-existent”, and since the mooncell only performs a check at the end of the day in the preliminaries, Sakura was within an inch of termination.
    (MC name) witnessing this called to her. Are you okay, he/she said.
    The observation of Sakura “being here” by a third party helped her recover her close to disappearing unconscious, and the subsequent nursing gave her a clear ego of “wanting to be here”. Her self-destruction was averted.
    What happened afterwards need not be said.
    When the next day comes, everything will be erased by the mooncell. Sakura wanting to continue this one day miracle used her higher class AI privilege to repeat the day she came to know the MC for 69 days.
    However as time passed, Sakura came to suffer from her self-contradiction as an AI and from the fact that she dragged (MC name) into this.
    “The Masters participating in the holy grail war will all die, barring one exception. No, even then (MC name)…..”
    Sakura continued to suffer from her desire to continue the loop for eternity and her feelings for (MC name)
    The decision she chose ultimately was to seal the 69 days worth of memory, the love she acquired, so she could return to being a normal AI.
    An AI cannot delete records.
    Because of that, she moved the memory to a backup machine to reset herself.
    Believing that to be the best choice for (MC name).
    But even if the memories in the mind are lost, the memories recorded by the body continue to live. Though she had forgotten everything and was back to being a normal AI, she was shaken by emotional values of unknown origin every time she talked with the MC.
    Meanwhile, the backup to which she moved her memory, couldn’t tolerate herself, and she decided her course of action and made her move as BB, the rebel plotting to destroy the system of the mooncell for a certain objective.
    The timing she took control of the far side of the moon was between the end of the fifth round and the beginning of the sixth in real time. Four Masters who were not defeated yet, (MC name), Leo, Rin, and Rani, and the irregular exception Jinako were kidnapped to the far side during the war while they were still alive.
    Matou Shinji, Gato, Julius were moved to imaginary space 0.00001 seconds before the firewall would have destroyed them after they were defeated, prolonging their flash of life.
    Regardless, CCC is a dream by BB.
    If the dreamer is no more, the world ought to return to a reality where nothing happened.
    By the way, the everyday scenery in the prologue that (MC name) saw in his nightmare was an artificial paradise modeled off the discarded 69 days.
    After pulling (MC name) to the near side, BB placed his digital body in the old school building, putting into a deep sleep and sealing him in a never ending dream.
    Normally, he would have lived peacefully in the looping everyday life, but the strength of his bond with his Servant, or his own will rejecting the peaceful days caused cracks in the artificial garden and (MC name) came to notice something was not right.
    In order to place (MC name) into deep slumber once more, BB reset the school building and tried to redo the dream, but the (MC name) escaped the reset and leaped into a deeper part of imaginary space
    It was a depth deeper than the bottom of Id.
    “The death of the collective unconscious” beneath the unconscious.
    What saved (MC name) who leaped into a region even BB cannot affect was the voice of the Servant whose fate was shared with his.
    Thus, the contract was sealed, and (MC name) woke up in the old school building left in the far side.

    Overcount 1999
    A mysterious phrase, mentioned by Twice.
    Per a decisive depletion of resources, the era where began the decline of human.
    Its cause is unclear.
    The resources of the Earth, theoretically beyond the consumption of man, came to depletion; the capacity by which life could be sustained was from the World lost.
    Upon its Core -- what could be called its very soul -- did the Earth sustain damage; or so he stated, but...

    Wiped Blank Earth [Other]
    The Earth after 2018, which Fujimaru Ritsuka had a glimpse of in the Lostroom.
    The Earth whose ground’s surface Texture has been pruned by the appearance of the Lostbelts.
    A “brand new shell of a planet” where the surface nature and traces of civilization have been lost. Where the pruned Texture (human history) has vanished to is unknown. The branches of the Trees of Emptiness that grew from the surface of the earth became a membrane that covered the Earth, creating a huge curtain at the boundary between the troposphere and the stratosphere, the tropopause. Although electromagnetic waves can be transmitted, substances cannot pass through this tent and terrestrial humanity has been trapped. It is conjectured that the original human history will not be returned as long as the seven Lostbelts aren’t cut off.
    It became a lifeless planet apart from the Lostbelts, but there seems to be some rare areas, buildings and lives that were “left behind from the blanking” during the blanking process.
    The blanking was conducted on December 31, 2017. The invasion of Trees of Emptiness began from space, and seven Trees of Emptiness fell on the surface of the earth, creating seven Lostbelts. The land of true history disappeared, and the Lostbelts were protected by storm walls. Then, after some time lag, the surface of the earth was blanked all at once. The blanking is considered to have spread radially from each Lostbelt.

Like the name Land of Steel indicates, a large part of the continent are now wild lands that are torn apart, covered by a tainted gray colored cloud.
    Food can't be grown, and the atmosphere is no longer suited for the animals.
    To put it in a human species way, a drastic end of a century. But even after the mother planet died, the humans were able to live on with its developed civil technology.
    Even the planet's end where people once imagined, couldn't bring an end to mankind.

Although it is harmful to humans, sometimes it gives an unique effect to their body, and some call it Ether. The Hundred A-rays, Human Species, Knights, are all new species created by this Gin. The energy transfer rate of the Gin scattered in atmosphere is incredible, and it resulted in a new level of warfare that was never possible on this planet.
    With A-rays who can take in Gin into their body and Demonic Swords crystallized by Gin, all the weapons of the old age became useless.

  16. [v] Notes - The Sky, it's Dark. [cloud sky]

    Sky covered by clouds. The thick layers of cloud hides the sky since the great war. It doesn't mean the sky is gray; they just can't see the sky.

  17. [v] Notes - The Sky, it's Red. [blood sky]

    The Sky in this world. Above the gray sea of clouds, there is not a blue, but a red sky.
    It's not because of a pollution, but from the blood of one of the Aristoteles that appeared near the end of the Great War, Type-Pluto.
    In order to not let Pluto enter the planet's atmosphere, the Six Sisters fought it and killed each other at the same time, and its blood covered the whole planet as a result. The gray cloud is said to be a shield that the Six Sisters placed.
    Within this red sky, the two Aristoteles that are prevented from entering the planet is floating like fishes that swim in the sea.

    After the death of the planet, there was a war between the survived human race and the Hundred A-rays.
    Mankind in order to survive, and the A-rays to rule the world.
    Under the Six-Sisters who united the unmassed A-rays, the human race were on the verge of defeat. Near the end of the war, mankind created the Knights and the Human Species, and it further killed the planet that's already dead.
    There was no victor to this war. It was interrupted by an intruder that suddenly appeared and nearly wiped out both sides.
