Shigekazu Sakanami is a 31-year-old voice actor employed by Blue March, an eroge production company established by Yayoi Aoyagi. He possesses brown hair, blue eyes, stands 1.80 meters tall, and weighs 72 kilograms.

He routinely maneuvers to assist Kanna during her voice acting duties, volunteering as a practice partner under the pretense of aiding her development. These interactions frequently intensify into persistent sexual advances that constitute harassment.
