Henblitz, whose full name is Henblitz Drout, serves as the vice-commander of the Liberion Order of Knights. He is a young man in his late twenties who holds a position of significant authority within the knightly order, acting as the second-in-command to his superior, Commander Allucia Citrus. He is often described as a "good man" and is recognized for his straightforward and sincere personality, a trait that becomes particularly pronounced when he drinks alcohol, as his demeanor is said to become quite passionate.

In terms of personality, Henblitz is a man of action who, upon first meeting the protagonist Beryl Gardenant, is openly skeptical and challenges him to prove his worth. This initial challenge stems from his position and his evident pride in the knightly order. He serves as a gatekeeper of sorts, requiring Beryl to demonstrate that his reputation as a master swordsman is not an exaggeration before he will accept him as a special instructor. However, this skepticism is not born of arrogance alone; once Beryl proves his immense skill, Henblitz undergoes a complete reversal of opinion. He becomes entirely won over by Beryl's abilities, expressing genuine respect and admiration for the older swordsman, and thereafter sincerely devotes himself to training and following Beryl's guidance.

Henblitz's role in the story is primarily as a high-ranking member of the Liberion Knights and a key foil to the protagonist. His early challenge to Beryl serves as a narrative device to confirm the protagonist's legendary prowess to both the characters within the world and the audience. He also acts as a confidant to his commander, Allucia. He is observant of her feelings and motivations, at one point directly questioning her about her intentions regarding Beryl, and later offering counsel after her duel with their master. His perspective is valued for its pragmatism; during a duel between Allucia and Beryl, when another student questions the fairness of Beryl's tactics, Henblitz states that in a real battle, winning is the only thing that truly matters.

His key relationships are mainly with Allucia, whom he loyally serves as her deputy, and with Beryl, whom he comes to respect as a master. His development in the story moves from a position of challenging authority to becoming a devoted disciple, having his initial doubts thoroughly defeated by reality. His sense of respect for Beryl is described as being so complete that he continues to train under and show sincere respect to the older man from that point forward.

Henblitz is notable for his immense physical power and his unique swordsmanship style. His strength is such that he is capable of stopping a rampaging cow with a single swing of a wooden rod, and he consistently ranks first in arm-wrestling among the characters, establishing him as the physically strongest member of the main cast. His swordsmanship is described as being like a false sword, a reference to his straightforward, linear attacks that rely on overwhelming power and speed rather than complex tricks. His signature technique is a devastating spinning cut where he rotates his entire body to deliver a slash. This move has several formidable advantages: it makes the sword's trajectory difficult to predict because the sword hand is hidden by his body, and the spin of his powerful physique adds significant centrifugal force to the blow. This technique is so powerful that it has been known to shatter wooden training swords, though the move does have a tactical weakness, requiring a preparation phase and leaving a brief opening after its execution, though Henblitz is skilled at using preparatory moves to prevent his opponent from exploiting these openings.
