Dante Renatos, who took the place of Emperor with his excellent swordsmanship, reincarnated 500 years later as' Helena', daughter of the Duke of Pereska.

The second life I didn't want.
I enjoyed everything I could in my previous life, and I tried everything I could.
At that point, anything done in this 2nd life would be troublesome and boring.

Then, Caesar, the prince, visits the Duke's residence to avoid a power conflict.
Helena, who recognized Caesar's talent, decided to become his swordsmanship teacher.

“I will make you emperor.”

It was only to soothe a boring life.
I started thinking of using my past life's skills to train younger students.

"If it's for Master, I can destroy this world."

Somehow, even if my student likes me, it seems like he likes me too much??
