Hakubo is a female android who holds the rank of captain within the OWEL Special Forces. Her most defining physical characteristic is that she shares an identical face with another individual named Yugure, a fact that creates an air of mystery around her. Her personality is marked by a gentle, warm, and calming aura, and she carries herself in a consistently relaxed and laid-back manner. This demeanor is particularly notable given her role in a high-stakes military unit. One of her distinct traits is a highly developed sense of smell, making her unusually sensitive to different odors in her surroundings.

Within the OWEL Special Forces, Hakubo is designed for and specialized in exploration and support missions. In this capacity, she is partnered with Yoiyami, another commander whose primary objective is to relentlessly pursue and capture their target, Yugure. While officially a participant in this mission to track Yugure, Hakubo does not appear to take the task seriously, showing a distinct lack of urgency and enthusiasm. Her nonchalant attitude stands in stark contrast to her partner's intense and determined focus on capture, creating a dynamic rift between them. This lack of aggression in her official pursuit raises questions about her true intentions regarding the mission and her relationship to her look-alike.
