Johan Frentzen (ヨハン・フレンツェン, Yohan Furentsen) is a supporting character in Shoukoku no Altair. He was a lieutenant general and was in charge of the 1st battalion and a part of duke Eisenstein's anti-war faction. He was after general Pineau's death temporarily appointed to be in charge of the Sud army.


Frentzen is a tall man of 190cm with a usually stern or troubled expression, commonly caused by exhaustion as he has been ill since early childhood. Despite his impressive height, he is a very scrawny-looking man and nothing indicates impressive muscle mass underneath his imperial uniform. He has short, seemingly curly, blond hair that has been cut above his ears and even his bangs are cut quite short. His eyebrows are thin and he has narrow, blue eyes and thin eyelashes. His attire consists of the imperial uniform; a black, high-collared jacket with long sleeves and intricate golden details and shoulders pads, black pants and a pair of black boots to complete the look.


Sickly since birth, Frentzen has had to fight for his own survival for a long time. He is determined and stubborn to the core. While he is weakened physically due to his condition, he is clever and a force to be reckoned with. Frentzen is the type to never give up and he has a great hope in not only himself but also the empire's ability to rise. Despite this, he acknowledges the fact that not all things can be obtained through hard work but believes that no matter what, you should act based on what you have been given. The empire is very important to Frentzen and he even went as far to claim that it was tied to his life[1]. However, while he is proud of the empire, he is able to think rationally and if faced with a heavy defeat, he would retreat for the sake of not putting his men through meaningless deaths.
