A cheerful and honest hard worker born and raised in Hokkaido, Special Week is a country bumpkin who aims to make it big in the world of horse girls. After losing her birth mother, she was raised by an adoptive human mother who treated her with thoughtful care. Despite never growing up around other horse girls, this never deterred Special Week as she trained hard with her mother in order to be accepted into Tracen Academy, Japan's most prestigious horse girl training school.
