Reincarnation World Militia

Reincarnation World Militia is the Silver Bubble world located in the shallowest layer of the Silver Sea. It served as the main setting for the series up until Arc 10.

Creation
Before the creation of the Reincarnation World Militia, there was the world created by the Creator God Elenesia. But when Elenesia passed away, her daughter and successor, Militia, created another world in its place.

Like most bubble worlds, the world was enveloped in conflict between the various inhabitants that lived in it due to lacking a Conformist to lead the world in the proper evolutionary path, as well as a Chief God, who would prevent Fire Dew from leaking from the world. The Creator God Militia observed the world that she had created and was saddened due to the chaos and strife the plagued it and the inhabitants in it as she hoped that there would be a way to change the world into a kinder one. However, due to her role as the Creator God being mostly completed with the creation of the world, she could only continue to look at the world which she considered as the only redemption for her, as she shared in the grief of others as punishment for her creating a unkind world. Meanwhile, her sister, the Destruction God Aberneyu, was plagued by her role as the destroyer and wished to be free of her fate of destroying others for the sake of providence, as she continued her role for the next several million years.

Mythical Age
Eventually, the conflicts between the inhabitants of the world would continue after a few periods of lulls between the conflicts as various species perished and the number of lives were lost, as the demons and humans would clash against each other in an attempt to destroy the other race, with the human being aided by the spirits and gods during the conflict. However, the demons were plagued by infighting as various demons competed to see who would become the ruler of their race, which helped the humans as they used subterfuge to try to pit the demons against each other, as the war potential of the demons would slowly begin to decline under such tactics. Some demons saw through the humans plans and moved to stop them and bring about an end to the war, with the leading person in that effort being Celis Voldigoad, the leader of the Phantom Knights, an order of powerful demons who defeated various human heroes and rogue demons. Eventually Celis would meet Luna Arzenon, whom he married and had a son with. However, Luna lost her life while giving birth to their child, as she was attacked by a squad of humans and later killed by the demon Graham, though not before giving birth to her son; Anos Voldigoad. Celis would force Graham to retreat, and worried about the fact that his son would be targeted for his incredible potential and his ability to unify the demons, Celis would leave Anos and work from the shadows to eliminate any demons who could pose a threat to Anos, thus facilitating Anos' rise as the ruler of the demons.

Great War
Over the course of the next several years, Anos would grow up and master the innate power that he possessed, growing in strength and amassing an army of loyal followers, with the leading among them being Shin Reglia, who would become his right hand man. Anos would also compete with other demons who tried to prevent his rise to power.

Anos would then lead his demon followers in the Great War against the humans and their allies, where he encountered the Hero Kanon; a powerful human hero who wielded the legendary holy sword Evansmana, which possessed the power to kill Anos. The two would battle and Anos would manage to overwhelm Kanon after destroying six of his seven sources, while Kanon would injure Anos with Evansmana to a fair degree. They would continue to meet and battle each other, gaining a unspoken respect for each others power and determination.

During that time, the Creator God Militia would take notice of Anos, as she decided that he could a valuable ally in her goal of bringing peace to the world. Thus descending to the earth's surface, she would talk to Anos, who was there for a battle. While initially bit hostile, Anos would gain an interest in Militia after he figured out that she was the true Creator God, as he inquired about the gods' nature, which he did not fully understand. Militia told him that the gods are order and that they do not have feelings as they are beyond such things. He then asked her about herself specifically, as she replied that she has a sister that she never met due to the way that order works, as he wondered about her sister's name, which Militia left in a snow and moon flower due to the fact that she had disappeared as the Month of Creation came to an end.

Eventually, Anos lead his army of followers to try to corrupt the Sun of Destruction, in order to stop more of his own people from being truly destroyed, as he met the God of Destruction Aberneyu, who was the cause of all of the destruction in the world. The two would talk as she revealed that she was tired of her role as the destroyer and welcomed being destroyed by Anos, and telling him that she had fallen in love with him as he was the only man who could survive being looked at by her divine eyes. However, Anos told her that he was there to take away the order of destruction, not to kill her as he help her gain partial control of her order by kissing her and temporarily robbing her of some her power, thus helping her fully awaken her emotions. He would then teach her to try to control her order by coming to the Sun of Destruction to visit her on occasions, as he would take a letter from her to her sister Militia for her to read. After that, he returned to Militia to deliver the letter and talk to her, as he asked her what she wanted. She replied that she wanted kindness in the cold world, which caused Anos to smile. His encounters with Kanon, Militia and Aberneyu brought a change in perspective to the Demon King as he started to work on another way to end the Great War. He obtained Aberneyu consent to turn her divine body into the Demon King Castle Delsgade and turn her order into the Reason Destroying Sword Venuzdonoa, as that would distort the order of destruction and make fewer people die. However, after he sealed her in Delsgade, he would use Venuzdonoa to split her consciousness from Delsgade and allow her to reincarnate as a demon in the future.

Meanwhile, the Sorcerer King Bomiras Heros lost his life to Celis and his Phantom Knights, with his territory of Midhaze becoming the battleground for various demons who tried to take his place as its ruler. Anos was the first to arrive with his followers and built Delsgade there, while defeating the other demons and their armies. After that victory, he had already taken control of half of Dilhade, which was the equivalent of ruling the country. At the same time, in that period, the order of the Phantom Knights would eventually be destroyed by Graham, as Celis was also killed by him and his head was taken by Graham, in order to wear it, thus increasing his own power and assuming Celis' identity.

After fully taking control of Dilhade, he created the Seven Elder Demon Emperors and made preparations to implement his plan to end the war. He personally invited Hero Kanon, the Great Spirit Reno and the Creator God Militia to Delsgade in order to talk about ending the war, as he offered a solution to end the conflict on peaceful terms for each race. The four of them would join forces to cast a cast a grand spell to create a wall to separate the races from each other for at least a thousand years, which would extinguish the seeds of conflict and allow the races to co-exist after the wall came down. The Hero Kanon and the rest agreed as they pooled their power together into Anos, who used up all of his magic to cast a massive version of the Four Worlds Wall , which would separate the world into four parts. Happy that his plan was accomplished, Anos thanked Kanon and told him that if Kanon was reincarnated 2000 years from that point, he hoped that it would be as friends, as his physical form couldn't withstand the combined power and collapsed, though Anos was able to prepare the requirements for his eventual reincarnation beforehand, with his source disappearing from the world for 2000 years.

Post-Great War
With the Great War over with Anos' "death", Kanon returned to Gairadite, where he was greeted with a hero's welcome for his supposed victory over the Demon King Anos. While most humans were glad that the war was over and peace had finally come, there were some who wanted to continue the war until the demons were completely wiped out, such as the commander of the Demon King Subjugation Army and Kanon's mentor; Jerga. He set about a plan to destroy the demons in the future by creating the Hero Academy to prepare the next generation of heroes against the demons and turn the magic of  into a magic that indoctrinates humans into hating demons. While Kanon pleaded with Jerga to stop for the sake of peace, Jerga used that moment of Kanon's carelessness to have him killed so that he wouldn't interfere in his plans. Jerga then gave his source to the Heavenly Father God; Nousgalia, who split it and would later attempt to use them to create magics that would be used to destroy the reincarnated Anos.

Kanon would revive himself but realize that it was too late to stop Jerga's plans, as he couldn't raise his sword against his kinsmen. So he created a plan of his own to protect the peace that Anos created and Anos himself; by creating a fictional Demon King; Avos Dilhevia, who would be a convenient scapegoat for the humans hatred. Kanon would approach the Seven Elder Demon Emperors, and obtain their cooperation for his plan, erasing their memories due to them being unable to lie to Anos and divided 6 of his sources among 6 of their members so that he could manipulate the legends of the Demon King, and only erasing Melheis Boran' memory due to not having enough sources to fuse to him as well. He would then begin to spread the rumors of Avos Dilhevia through the world, and the repeated the process across many lives due to continuously reincarnating as a demon.

Meanwhile, Nousgalia would attempt to create the magics to destroy Anos, but Militia interfered with him. While she was unable to stop him completely, she was able to make sure that the magic of Source Womb  would be born without any hatred for demons. Realizing that the peace that was achieved was built a fragile balance that could collapse at any moment. In attempt to create a more permanent peace, Militia created Ennesuone, an order which would use Anos' magic to create new life. However, that action went against her own order, thus rendering her unable to return to the Azure Sky of the Gods due to her fighting against her own order as well as  blocking her path. While unable to return to the Azure Sky, she was able to send Ennesuone there, in hopes that she could be born with the assistance of her best friend; Wenzel, the God of Birth. Militia also left details to Ennesuone that Anos would eventually reach the Azure Sky and the necessary requirements to complete Ennesuone's creation.

At the same time, Nousgalia continued to plot to find a way to destroy Anos and release Aberneyu for Delsgade. Taking advantage of the romantic relationship between the Great Spirit Reno and Shin Reglia, Nousgalia possessed Shin during the couples wedding night tryst, as the encounter produced a child that also shared Nousgalia's divine power. Nousgalia later appeared and removed the child from Reno's womb, thus allowing for the "Child of God", who embodied the legends of Avos Dilhevia, the Demon King of Tyranny, to be born. However, Reno began to disappear due to violating her own lore, though not before sending her child to the future to escape Nousgalia's influence. Shin would take over as the leader of the spirits in Reno's absence, thus becoming known as the Spirit King.

Militia would then create the Underground World, which was able to support life underneath the earth. Eventually, two countries were formed; Giordal and Agaha, as they quarreled over religious differences. The Underground World was the place where the Selection Judgement was first held, as Militia chose one young girl called Arcana to serve as her Selection God, and allowing her to win the Selection Judgement, thus paving the way for her to become an acting god. However, Militia was trying to end the Selection Judgement for the good of the mortals, as Arcana saw this as a betrayal and killed her with the help of Heavy Thunder Sword , which was lent to her by a Agaha Knight called Boldinos, who was manipulating her. Before dying, Militia split her divine body and transformed into the Science Temple of the Gods' Age Everastoanzetta and used Silica to reincarnate. Arcana would obtain Militia's order and took of the name of Genudunub; the God of Lies and Betrayal, forming the country of Gadeisiola and made Boldinos its king to wage war on Agaha, Giordal and the gods. However, she later discovered Boldinos betrayal and tried to fight him, but was killed although she was able to resurrect later.

Magical Age
As the centuries passed, the hostility between all of the species lessened overall, with  disapatting 1000 years after it was originally created, allowing the races to intermingle, with the era becoming known as the Magical Age.

2000 years after the Great War, Demon King Anos would reincarnate as a child to Gusta Raizeo and Izabella Raizeo. Growing up with the aid of magic, Anos would begin to attend the Demon King Academy and befriend various students there such as Misha Necron,Sasha Necron, Misa Ilioroagu and Lay Glanzudlii, who would become his close confidants and allies. Anos would become aware that history was altered and that his identity as the Demon King of Tyranny was usurped by a fake Demon King named Avos Dilhevia.

Eventually, Anos was able to figure out that Lay was the reincarnation of Kanon, as well as the true identity behind Avos Dilhevia, whom he prepared as a scapegoat for humans to have their revenge on at the cost of his own life. Unwilling to let his friend sacrifice himself, Anos would fight Lay to stop him from fulfilling his plan, as the two later teamed-up against Jerga, who was the culprit behind the humans' hatred towards demons.

After that, Anos would have to contend with Nousgalia, who was seeking to eliminate Anos and revive Aberneyu with the help of the "Child of God", who was the order of the Demon King's destruction. Eventually, it was revealed that Misa was the "Child of God" as well as the great spirit that embodied the legends of Avos Dilhevia, with Nousgalia managing to awaken her to her Avos form. She tend proceeded to try to usurp Venuzdonoa from Anos and kill him, but was defeated by him and Lay. After that, Anos managed to take advantage of her spirit nature by altering the legends of the Demon King of Tyranny to reincarnate Misa as a pure spirit, thus making her the dominant personality and allowing her to access her Avos powers freely.

During field trip to Gairadite, Anos would meet Arcana, who was serving as the pact god to Ahide Alobo Agatse, a priest of Giordal who was seeking to subjugate Azeshion at the request of Lisius Angelo Gairadite, who was seeking to turn him people into dragonnewts in the service to the gods. Anos was able to defeat Ahide and convince Arcana to join him, as he had managed to answer her question about the Almighty.

Growing curious about the fusion of Misha and Sasha, as well as Arcana's lost memories, Anos traveled to Giordal to obtain the cooperation of the Trace God Rivershnedd. During his time in the Underground World, he would encounter his "father"; Celis Voldigoad (who was actually Graham wearing Celis' head). Eventually, Anos would stop Giordal head priest; Gorloana Dero Giordal's attempt to destroy Dilhade, as he would accept Arcana as a foster sister.

However, the Underground World's heavenly canopy began to collapse as Anos joined forces with the leaders of the Underground World to create a new Heaven Pillars Support Sword by transforming the feelings of the underground inhabitants via , as he also defeated "Celis" by applying a beheading curse on him.

Learning that Militia was keeping his lost memories into artifacts called the Creation Stars Erial, Anos and his group set out to find them while also fighting against the Hero Kasim and the Sorcerer King Bomiras Heros. Through the memories he obtained from the Creation Stars Erial, Anos learned that his real father was killed by Graham, who was still alive and waiting to fight Anos. Graham revealed that the being inside Viaflare Wips Gadesiola's womb would be his grand experiment, as the two misfits clashed. While initially appearing an even match, Anos was able to defeated Graham by locking away his source inside of his own source, where he would be destroyed in the next several millenia.
