Yukikaze appears in the anime series "B: The Beginning" and its sequel "B: The Beginning Succession". He is a male researcher affiliated with the organization White Cage (Jaula Blanca). After an attack on the Jaula Blanca facility, he continues next-generation research and analysis alongside surviving colleagues. Yukikaze demonstrates strong leadership and commands respect among peers, relying on data-driven conclusions; he presents evidence stating that "theoretically, Asagiri is more powerful and has greater potential than Koku".

Physically, Yukikaze has silvery hair, ice-blue eyes, and straight-faded eyebrows with no facial hair. During the Cathedral fight, he sustains an injury to his left ankle. By the conclusion of Episode 18, he is shown fully healed and alive.
