Sayo

サヨ

She departed with Tatsumi and Ieyasu to raise funds for their village. During the journey, they were ambushed by night bandits and became separated. Sayo managed to remain with Ieyasu, while Tatsumi was cut off from them. Aria subsequently invited Sayo and Ieyasu to her mansion, serving them a drugged meal that caused them to lose consciousness. Sayo was then tortured to death; however, she refused to submit to Aria and her family, even at the moment of her death. Tatsumi personally slays Aria after learning the truth about her and her sadistic family. It is possible that Tatsumi was in love with her, as the illusion shown by Zank revealed her to be the most important person in the world to him.
Sayo was observed carrying a bow and a stack of arrows. She appeared to possess strong combat abilities and was presumably a well-trained archer, as Tatsumi stated that both she and Ieyasu were strong.
