Jerga

"My hatred has become the order of this world! Humans and heroes shall join hands to eliminate demonkind. That is the rightful form of this world! Resist all you want, but you shall atone for your sins!"

- Jerga to Anos Voldigoad in "May Love Fill the World"

Jerga (ジェルガ) was the King of Gairadite and commander of the Demon King Subjugation Battalion two thousand years ago.

Appearance
Jerga was a middle-aged man with a goatee and grayish-brown hair. He retains the same appearance as conscious magic but with a transparent spectral visage. His form later changes into that of a golden armored giant.

Personality
Jerga held an intense and raging hatred toward demons. Blinded by this hatred, he was ignorant of the fact that he had turned into the very evil he accused the Demon King of being. His madness and insanity had no end, as he wanted to annihilate every last demon from existence. He claimed that his hatred was that of all the humans; however, he had no problem killing multiple humans if it meant getting his revenge.

History
Jerga was Kanon's teacher and the hero that preceded him. Due to the death of his wife and child at the hands of the Demon King of Tyranny Anos Voldigoad, Jerga held a deep grudge against him and demonkind. Even after Anos sacrificed himself to end the war, Jerga did not change. He knew the Demon King would reincarnate in the future, so he set up the Hero Academy to pass on his hatred to future generations. Afraid that people would forget their hatred of demons, Jerga worked with the gods to transform his source into two forms of magic: Jerga and Eleonore. The gods also fused the magic of Jerga into Aske, resulting in anyone who uses it sharing his feelings of hatred and resentment towards demons.

However, Kanon strongly opposed the academy and its purpose, wanting peace with the demons instead. Fearing that he may complicate things, Jerga had his comrades pretend to be on Kanon's side before killing him. In doing so, he ensured his plan would be successful. Afterward, he altered the written history to ensure demons were viewed as cruel and evil, and even hid the fact that the Demon King willingly gave up his life to bring peace.

Hero Academy Arc
After Diego is defeated and abandoned by his battalion, he casts Aske, allowing Jerga to resurrect into a giant body made of holy magic. Lay attempts to destroy him, but Jerga is unaffected by Evansmana because the holy sword cannot cut another holy entity. Jerga then attempts to detonate all ten thousand Zeshias with Gavuel, but he is stopped by the fused form of Sasha and Misha. He waits until they run out of magic power before trying again, only to be stopped by Anos, who cast Rivide to stop the Zeshias' time.

Anos quickly destroys Jerga's source with Vebdoz, but he reforms immediately since he has already become part of the world's order. Jerga then forcibly drains the Demon King Subjugation Battalion's hope using Aske to imbue himself with armor and a holy weapon. He uses the holy sword to destroy Anos' source, but the Demon King recovers immediately using Agronemt. The fight is then interrupted by Lay, having gotten all seven of his sources back. The hero cuts off Jerga's legs with Evansmana, surprising him, as his immunity was stripped by Venuzdonoa. Anos reveals that he summoned the Demon Castle Delsgade to the battlefield while Jerga was distracted. The conscious magic is then cut down by Anos and Lay using their signature swords, thereby losing his power.

Anos explains that while his hatred went into Jerga, his desire for peace went into Eleonore, leaving him in emotional conflict. He also tells Jerga that he remembers killing his wife and child because they were tough opponents and that he used Syrica to reincarnate them afterward. Just before killing Jerga with Venuzdonoa, Anos gives him a one-shelled necklace and uses Syrica on him as well, as a way of wishing him to reunite with his family after reincarnating.

Abilities

 * Immense Magic Power: Despite being in his old age, Jerga exuded far more vigor and magic than the average human due to being a former Hero. After siphoning all of humanity's hopes with Aske, Jerga's power increased dramatically, as he was able to fight on par against Anos and Lay.
 * Immunity to Evansmana: Jerga is completely unaffected by Evansmana since a holy sword cannot destroy another holy being. It cannot destroy Jerga or sever his fate, as he would simply regenerate after being cut. However, this was made possible after Anos used Venuzdonoa to destroy reason and order.
 * Conceptual Existence: After his source was turned into magic, Jerga became a world Order, a law or concept that makes up the world. In Jerga's case, it was the hatred toward demons. As long as the magic Jerga exists in the world, Jerga will never be destroyed. This is shown when Jerga reforms after being destroyed by Anos without leaving a trace. Jerga stated that even if every single human were to be killed, the magic of Jerga would only stop working temporarily and would not be destroyed.

Kanon
Jerga was Kanon's mentor, who trained him to become the hero he became. He cared greatly about Kanon, as he donated a majority of his source to Kanon, allowing the young hero to obtain six additional sources. Jerga held immense faith in Kanon and was willing to stake humanity's future on him, believing that he was the only one that could defeat the Demon King of Tyranny. He constantly encouraged Kanon to exterminate the demon race, as their races couldn't co-exist together and that peace could only be achieved with their eradication.

However, when he discovered that Kanon had no intention of continuing the war, Jerga was disappointed in him and had his allies kill Kanon so that he would not interfere with his plans.

Anos Voldigoad
Jerga utterly despises the demon race and especially the Demon King of Tyranny, Anos Voldigoad, whom he blames for the death of his wife and child. Anos, in return, replies that Jerga wasn't the only one that experienced tragedy, as Anos was born from his mother's corpse after humans killed her.

Trivia

 * Jerga somehow knew about Venuzdonoa, even though Anos hid its existence and those who found out died.
 * The information most likely came from Nosgalia, who was aware of its creation and was planning on restoring the Order of Destruction from which the sword was created.
