Heimin Shusshin no Teikoku Shoukan, Munou na Kizoku Joukan wo Juurin shite Nariagaru

Hazen Heim, a newly appointed imperial general, is demoted to the front line because he is a commoner. There were a lot of incompetent people, such as "a trash superior who takes advantage of his position to steal the achievements of his subordinates", "an evil subordinate who keeps bullying people below him", and "a top who is too opportunistic to do anything''.

However, Hazen has the experience and overwhelming ability as the strongest magician that he cultivated in his previous life. He slaughters his malevolent subordinates in accordance with military law, and completely refutes his superiors who complain. He achieved extraordinary results, such as making peace with a hostile tribe by teaming up with a genius girl, and defeated all the annoying bosses!
