Zushioumaru was once the cherished companion of Aria Arakawa, but after becoming separated from her, he was taken in and cared for by Dr. Sumida. Out of profound gratitude, he volunteered to serve as a test subject for SCM device research. Driven by an indomitable spirit and fierce loyalty, he donned the SCM to seek justice against Setagaya, who had wrongfully framed the doctor. Upon reuniting with Aria, this selfless canine made the deliberate choice to become a slave, ensuring his beloved owner would remain under the protection of the formidable Yuka Ota.
