Black Clover (Male! OC insert)

Kieth, a prisoner and slave that serves under the House of Silva. He doesn't know his parents. He was only four when he was took in as a slave by the Silva Family. Once he escaped, he heard about the Magic Knights who are heroes of the Clover Kingdom, thus he becomes one in order to protect the ones he cares about. But still, his hatred and anger towards the House of Silva remains, causing him to lose his emotions and self control.

Sooner, someone helped Kieth overcome his devastation against the royals, therefore he pledged to become the Wizard King!
