Jerga

"My hatred has become the order of the world! Humans and heroes resent the demons and will destroy them. This is the righteousness of this world! No matter what you do, you must atone for your sins!"

- Jerga to Anos Voldigoad

Jerga (ジェルガ) was the King of Gairadite 2,000 years ago, and commander of the Gairadite Demon King Subjugation Army.

Appearance
As a human, Jerga had the appearance of a middle-aged man with a goatee.

As living magic, Jerga appears similar to how he was in his human form, but has transparently spectral visage. His form later changes into that of a golden armored giant.

Personality
Jerga held an intense and raging hatred towards 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, not wanting to rest until every last demon was annihilated 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. Overall, his negative traits is the reason why Kanon began to see him as an example of "humanity's weaknesses" and why he preferred to reincarnate as a Demon.

History
Jerga was Kanon's teacher, and the hero that preceded him. Due to the death of his wife and child, Jerga held a deep grudge against demons. On one occasion, the Demon King of Tyranny Anos Voldigoad, came to Azesion to advocate peace with Kanon, but Jerga interrupted their conversation and attacked Anos, only to get severely injured.

Even after the four walls were made and the Demon King died, Jerga's hatred did not change. He believed that the battle would not end until the Demon King was completely dead, with that in mind, he set up the Hero Academy as a way to pass his resentment to the future generations. Kanon was strictly against the academy and its purpose, wanting peace with the demons instead. The tensions between the two almost resulted in a civil war between the humans, with each side having many allies. However, Jerga waited for Kanon to drop his guard, and had his allies kill him. In doing so, he made sure that his hatred could be passed on. He then altered the written history to make sure demons were viewed as cruel and evil, and even hid the fact that the Demon King willingly gave up his life to bring peace.

But he was still afraid that people would forget their hatred of demons. So, working with Nosgalia, the Heavenly Father God, at the cost of his life, he transformed his source into two forms of magic; Jerga and Eleonore. He also had Nosgalia fuse the magic of Jerga into Aske, resulting in anyone who uses it sharing his feelings of hatred and resentment towards demons.

Hero Academy Arc
After Diego is defeated and abandoned by his army, he casts Jerga, allowing Jerga to resurrect into a body made of holy magic. Lay attempts to destroy him, but he explains that, as his body is made of holy magic, he couldn't be killed by the holy sword Evansmana. Jerga then attempts to detonate all 10,000 of the Zeshias with Gavuel, but he is stopped by the fusion of Sasha and Misha; Aisha. He waited 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. Jerga then uses Aske and Jerga to forcibly drain the Demon King Subjugation Army's hope to imbue himself with holy armor and sword. He attempts to kill the group, but is distracted by Misa's Fuska. Jerga injures Anos, damaging his source, but Anos immediately recovers, having healed his source with Agronemt.

The fight is then interrupted by Lay, having gotten all 7 of his sources back. The hero cuts off Jerga's legs with Evansmana, surprising him while Anos reveals that he summoned the Demon King Castle Delsgade to the battlefield. The living magic is then cut down by Anos with Venuzdonoa and Lay with Evansmana, 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 afterwards. Just before killing Jerga with Venuzdonoa, Anos gives him a one-shelled necklace and uses Syrica on him as well, as a way of saying he wishes him to reunite with his family after reincarnating.

Abilities

 * Immense Magic Power: Jerga was stated to be a powerful as a human due to being a former Hero, despite being 60 years old, although it was noted that he wasn't as powerful as Kanon. After he became the magical order of the world, Jerga's power increased dramatically due to being fueled by the feelings of humanity via Aske, as he was able to fight on par with a weakened Anos Voldigoad and a weakened Lay Grandsley.
 * Immunity to Evansmana: Jerga is completely unaffected by Evansmana because a holy sword cannot cut something that is truly holy. Evansmana cannot destroy Jerga, nor can it sever his fate. However, this was made possible after Anos used Venuzdonoa, which can 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 towards 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 willing to stake the future of humanity on Kanon, believing him to be the only one capable of defeating the Demon King of Tyranny. However, when he discovered that Kanon had no intention of continuing the war, Jerga and his allies killed him.

Anos Voldigoad
Jerga utterly despises the demon race, 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 she was killed by humans.

Trivia

 * Jerga somehow knows about Venuzdonoa, even though he never saw it 2,000 years ago and those who did died.
 * The information most likely came from Nosgalia, who was aware of Venuzdonoa and its creation as his goal was to unseal the God of Destruction, Abernyu, who was sealed in Demon King Castle Delsgade as Venuzdonoa was created by using the order of destruction.
