Western Fantasy: Retired, So Who Needs to Be a Sword Saint?

My name is Falvina. I was probably a Sword Saint in the past, but one day I was told that the Hero had defeated the Demon King and brought peace to the world, and that I seemed to be out of a job.

So, in order to put food on the table, I set out on the path of an adventurer.

Alongside a young girl who seems to have come from the future?

But the farther I go, the more I realize I am beginning to uncover the truth about the world...

Step by step, it is coming closer to me.
