Benga

is an officer at Hōzuki Castle.

Personality
Benga is a strict disciplinarian. He dislikes intellectual pursuits, considering strength to be the only reliable form of maintaining order. Despite being Mujō's subordinate, he looks down on him, thinking him to be soft on the prisoners because of his belief in the possibility of rehabilitation.

Mujina Bandits Arc
Benga lectured new prisoners on the rules of Hōzuki Castle at their arrival, being rude to Boruto even as he demonstrated interest in knowing what the rules were, and beat him when he expressed concern for Haie, who activated Mujō's branding by trying to escape. Later, he welcomed Sarada when she posed as a journalism student researching the prison. He answered her questions, shared his opinions, and showed her around the different areas of the castle.
