Shikikoza

Shikza was a mid ranking noble, assigned to protect Main with Damuel During the Trombe extermination.

Personality
He has an inferiority complex to Main due to her being a commoner with a large amount mana.

Coming from a mid noble family, it was generally seen as an embarrassment to a middle class family to have someone of such low mana reserve, which why he was sent to the temple. He was only brought back to the family due to the purge which resulted in a lack of nobles. All this feeds in to narcissistic personality and his attack on Myne.

History
Shikza was a Mednoble, making him higher status than Damuel. Born with relatively low mana, on par with a lay noble, he was originally sent to the temple. He was raised as a blue priest but was recalled back to his family after the purge due to a lack of mana within Ehrenfest. Shikza, who's family was close to the High Bishop, had been informed about the commoner shrine maiden, Main.

Due to his Endangerment, and failure to protect Main, he was executed as punishment. His family was also required to pay half the cost of Myne's replacement ceremonial robes.

After Shikza’s death, Jilvester arranged a deal to keep his family from harassing Main. As punishment Jilvester forced the father to sign a contract promising to never interact with Main in any way, shape, or form ever again on top of paying a large sum of money. In exchange, Shikza's failure was not reported, and his cause of death changed to something more honorable.

 * The Japanese version of his name is "Shikikoza", which spelled backwards means "Small-Fry Knight" (zako kishi). The English translator was going to change to a different name in English with a similar meaning for localization, but the author requested a name that sounds similar to the original because of the anime.
