Sayo

left|thumb|Sayo offering Gyomei her portion of fish. Not much is known about Sayo, other than that she likely behaved like a typical toddler. However, she was shown to be particularly selfless and kind as shown when she offers Gyomei her fish dinner after seeing that the monk himself was not eating, worriedly pointing out his thin physique. In the present, Sayo gained the maturity to retroactively realize her disjointed testimony led to Gyomei's arrest, and that caused her to regret her words.

Sayo has black, short hair styled in a blunt bob with a fringe. During her time at the temple, she typically adorned herself in a traditional light-pink kimono embellished with delicate floral patterns. Like the older children, she did not wear any shoes.

As an ordinary human, Sayo did not possess any additional powers or abilities.
