Yoshiro and Soh are one being forced into a cycle.
Yoshiro is forever reborn to be the Maiden.
Yoshiro holding a mask at the end, the new Maiden seen with a mask hints she's been reborn.
I thought she became the new Soh but considering lore, they each play their roles forever.
Just a theory but this one seems more likely than Yoshiro and Soh switching roles.
