Sayo

Bio
Sayo is a cheerful, kind girl, and childhood friend of Tatsumi and Ieyasu that set out to earn money for their village. On the way, they were attacked by night bandits and got separated. Sayo managed to stay with Ieyasu while Tatsumi was separated from them. She and Ieyasu was then invited by Aria to her mansion, and provided them with a meal that was drugged, making them lost consciousness. She was then tortured to death, and didn't submit to Aria and her family even after her death.

Equipment and Skills
Sayo was seen carrying a bow and a stack of arrows. She seems to have good combat abilities and presumably, good archery skills, as Tatsumi stated that both she and Ieyasu were strong.
