Prologue: The Developer's Tragic Fate
Her childhood friend joins hands with the demons, framing the protagonist—the daughter of a count—for treason and sending her to the executioner's block.
Yet, a second chance is bestowed upon her. Inheriting the will of a legendary greatsword, she is reborn to wage one final, climactic battle against the childhood friend who has ascended as the Demon King.
...Or so went the plot of the game I was developing. Personally, I thought it was a pretty solid narrative for an action game.
That is, until I ended up reincarnated as that very protagonist!
