Sakuya is a young girl with light brown eyes and short hair. She wears golden hoop earrings much like Kuuya, but her ears are upright. She wears a dress with various shades of blue, with white stripes and a yellow sash with a red string.
Sakuya is known to be a shy, yet compassionate character who always looks out for her friends' best interest. As such, she is very much loyal to Kuuya.
She also demonstrates a great amount of determination and selflessness when she cripples herself to save Kuuya. Sakuya puts herself before others, even if it is at the cost of her own safety and well-being.
Being a close friend and trusted servant of Kuuya, Sakuya is introduced when she is sent to retrieve Hakuoro for a meeting. It is later discovered that Kuuya, wanting to create an alliance for Tuskuru and Kunnekamun, offered Sakuya as a bride to Hakuoro.
Later, when Genjimaru defects to Tuskuru, it is revealed that Sakuya requested Genjimaru to have the tendons in her legs cut to gain Hakuoro's trust. This action, however, only happens in the game, as the anime adaptation does not mention Sakuya's actions.
