Shikikoza

Shikza (シキコーザ Shikikooza) was a mednoble, assigned to protect Myne with Damuel during the trombe extermination.

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

Coming from a mednoble family, it was generally seen as an embarrassment to a middle class family to have someone of such low mana reserve, which is 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 his narcissistic personality and his violent behaviour towards Myne.

History
Shikza was a mednoble, making him higher ranked than Damuel. Born with relatively low mana, on par with a laynoble, he was originally sent to the temple. He was raised as a blue priest but was called 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 blue shrine maiden, Myne.

Due to his failure to protect Myne, even endangering her, he was executed as punishment. His family had the choice of saving the house and accepting that Shikza died a heroic death or be executed alongside him. His father chose the first which also required to pay a quarter of the cost of Myne's replacement ceremonial robes. After Shikza’s death, Sylvester arranged a deal to keep his family from harassing Myne. As punishment Sylvester forced the father to sign a contract promising to never interact with Myne 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 was changed to something more honorable. Due to Shikza's execution, his mother has a grudge against Myne, as she was happy that his son finally returned home, just to be executed because of a commoner.

Trivia

 * The Japanese version of his name is "Shikikōza", which spelled backwards means "Small-Fry Knight" (雑魚騎士, 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.
