The character's name is spelled Volkan. He serves as a military instructor at the academy where protagonist Godo trains to become a space pilot. Volkan embodies his dystopian society's emphasis on ruthlessness and emotional detachment, standing in stark opposition to Godo's innate compassion.

Tasked with testing cadets' combat readiness through live-fire exercises, Volkan orders Godo to kill a group of small, furry alien creatures intended as target practice. When Godo balks, recognizing their sentience and exclaiming "they're human beings!", Volkan coldly terminates them himself. This act underscores his adherence to the society's dehumanizing values and his function in suppressing trainee empathy.

Volkan relies on harsh, sneering teaching methods, openly ridiculing Godo for displaying emotional attachment to his robotic caretaker Olga. His physically imposing presence and actions reinforce the narrative's critique of authoritarian systems that prioritize obedience over ethical considerations.
