Diego Ijeiska

Diego Ijeiska (ディエゴ・イジェイシカ), formerly known as Diego Kanon Ijeiska, was the director of the Hero Academy and teacher of the selective class "Jerga-Kanon". He is a source clone created by Eleonore Bianca.

Appearance
Diego keeps his brown-gray haired in a neat ponytail and is slightly unshaven. He is usually seen wearing a black trench coat and he has notable bags under his eyes.

Personality
Like most of his elite students, Diego possesses an extreme amount of arrogance towards the Demon King Academy and its students. This obsession of human superiority is demonstrated when he worships the Holy Water given to humans by the Gods and believing that Demons are inferior.

His ego is perhaps even bigger, to the point of cheating in the exams and showcases to attempt to humiliate the Demon King Academy.

History
Diego is a source clone specializing in education, and the most susceptible to Jerga's voice inside Asc. It's mentioned that hundreds of instances of Diego have come and gone.

As with the top 4 students of "Jerga-Kanon", he believed to be Kanon's reincarnation and wrongfully took his name.

Hero Academy Arc
The first Diego introduced was the headmaster of the Hero Academy and the teacher of the "Jerga-Kanon" class. During the inter-academy exam, he discovers Misha in the temple beneath the holy lake and brutally attacks her before being stopped by Anos Voldigoad. After being killed and revived by Anos, Diego was turned into a demon to reflect his ugly heart. As if this wasn't enough, his source was also removed from his body and injured, causing Diego to writhe in pain. Anos did so to show him who the real Kanon was, someone who despite having 7 sources and therefore took several times more pain, continued fighting for peace. In the end, Anos crushed his source and ended his existence.

The next day, another Diego shows up to class to inform them that the students of "Jerga-Kanon" will be absent due to fatigue. Anos noted that he had the same magic wavelength and source as the Diego from before, but no recollection of what happened yesterday. After Avos Dilhevia stole the Holy Sword Evansmana, Diego sent a magical broadcast across Azesion to inform them about the Demon King's return and spread anti-demon propaganda, before finally declaring war on Dilhade.

He personally led the subjugation army, but even after the "death" of the Demon King and the retreat of the demon army, Diego still wanted to keep going until he killed every last demon. His military adjutant protested, so Diego cut off his arm. Eventually, all of the soldiers protest as well, causing Diego to become increasingly furious. This leads to him getting possessed by Asc before falling unconscious and collapsing to the ground, as Jerga makes his return from the dead.

Great Spirit Arc
Sometime after Jerga's defeat and the peaceful conclusion of the war, Diego was punished for violating military law. Despite the human army winning, he tried to continue the war by cutting off his second-in-command's arm. The authorities also found out that Diego had been planning war against Dilhade for quite some time; as a result, Azesion wanted to settle this by declaring him a war criminal. In addition, with the appearance of the real Kanon and his usage of Evansmana, Diego and the other heroes were declared as fakes and stripped from the name "Kanon".

Equipment

 * Holy Sword of Light Enhale: A sword that rejects all demon power. Its special characteristic is duplicating itself using the holy light from the original. For this reason, Diego and all of the source clones have Enhale.

Eleonore Bianca
Diego has a deep hatred of Eleonore and deems her a failure due to her inability to hate demons. He views her as a tool below himself with the purpose of killing demons.

Zeshia Bianca
Like Eleonore, he views Zeshia as nothing but a mindless tool that should be used to kill demons. He possesses no sympathy for her and is more than willing to order dozens of Zeshias to perform suicidal tactics.
