Machias Regnitz is a member of Class VII, and a major character in the Cold Steel arc. Machias is the son of Carl Regnitz, the governor of Heimdallr. He grew up with his family and sister, until a fateful day that scarred Machias, and left him with a deep hatred for the nobility. He chose to go to Thors Military Academy, being placed into Class VII, a place that will have both commoners and nobles in the class, much to his surprise. Machias is a hard worker and a prodigy student, holding himself to strict standards, as he is an overachiever. He is brash towards others, especially when they poke fun at him. Easily angered, he can start verbal confrontations with others, especially when it comes to political and social issues. 

Machias has a medium-low voice, and can change emotions rather quickly. He has a more reserved/defensive tone, and most of his non-battle lines consist of emotions involving anger, surprise, egotism, and shock. *Note: If you voice crack during parts where you hit high points of your pacing, it is in character for him, just don't voice crack every other high point, this is just so that you aren't worried if you have that one voice crack at a high point*
