In the 'Black Mask Hole Story', if it's a mystery - type story, the main character could be a detective - like figure who wears the black mask to hide their identity while they investigate the strange hole. There might be a local who has some knowledge about the hole and its secrets, and they could be another important character. And perhaps there is a shadowy figure in the background who is somehow connected to the hole and the black mask, either trying to protect its secrets or use it for their own malicious purposes.
Well, it's hard to say for certain. But if we think about it, the main characters might include the victims of the Black Death. After all, they are the ones directly affected by the plague.

There could also be people in the community who had to deal with the aftermath of the disease, like those who had to bury the dead.
