Diego Ijeiska

Diego Kanon Ijaysica (ディエゴ・カノン・イジェイシカ, Diego Kanon Ijeishika) was the director of the Hero Academy and teacher of the Selection Class "Jerga Kanon". He is a humanoid magic created by Jerga through 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 root clone specializing in education, and the most susceptible to Jerga's voice inside Sanctuary . It's mentioned that hundreds of instances of Diego has come and went.

As with the top 4 students of "Jerga Kanon", he wrongfully assumed the role of Kanon's reincarnation.

Plot
The first Diego introduced was the headmaster of the Hero Academy and the teacher of the "JergaKanon" 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 the 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 "JergaKanon" will be absent due to fatigue. He has the same magic wavelength and origin 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 Azeshion to inform them about the Demon King's return, spread anti-demon propaganda, and finally to declare war on Dilhade.

Eleonore Bianca
He has a deep hatred of Root Womb , deeming her as a failure in every instance that was born without fail. Due to her inability to hate demons, he views Eleonore as a tool (below himself) to be used to kill demons.

Zeshia Bianca
Like Eleonore, he views Zeshia as a mindless tool that should be used to kill demons. He possesses no sympathy for her, and deems her below him as someone who should be ordered.
