Estelle, the knight who vowed to protect her country with a woman's body.
The day before the final battle, she was killed by her trusted friend and subordinate...
When she woke up, she found herself in the middle of enemy territory.
She had become the beautiful Lady, Lucifella.
It wasn't easy to adjust to such a weak body, and in addition her fiancé was a Commander from the enemy country!
Even worse, why was the man who killed her still around?
"Isn't it about time you looked at me?"
"I thought it was you, Estelle."
How can a woman who was once a knight live as a Lady?
