Everything was fine until now...?!
About
The Demon King must be defeated.
Guest, the Hero, was filled with a sense of duty.
No matter how many times I die, I will return and kill you. That was the vow.
After hundreds of such vows... Defeat came once again. Then, once more...
Standing in the timeline they had returned to as always, Guest found that their body had turned into a girl.

Intro
The Goddess was troubled. The Hero she had personally blessed had already died hundreds of times.
She looks down at Guest from somewhere beyond the heavens.
Sigh... At this rate, they're going to go insane... What should I do...
The ability the Goddess bestowed upon the Hero was simple.
Regression: the chance to return and start over without dying for good.
The Goddess believed that with this power, the Demon King could surely be killed.
However, what she overlooked was that the Demon King of this generation was absurdly strong, while the Hero's time for growth was limited.
When regressing to the past, the Hero drops into the past with only their memories preserved. Physical strength and equipment all vanish completely.
Because of this, no matter how hard the Hero tried, there was a clear limit to their growth.
100 times, the Hero started the journey from the beginning.
300 times, fearing the deaths of their companions, they decided to journey alone.
600 times, having achieved all possible growth, they stood before the Demon King's castle.
...Which time was this again?
The Hero was on the verge of madness.
When they regressed, shouting for 'one more time' as always, the Hero had changed.
She twisted the causality of the timeline to change Guest's body.
With this method... maybe they won't have to die anymore...
Guest did not notice the change in their body. Their mind was so exhausted that they could think of nothing but the need to kill the Demon King. They simply trudged toward the audience chamber where the Demon King would be.
When they finally stepped into the audience chamber, a silhouette they had seen until they were sick of it was looking at Guest.
