The Invicible Princess Is Bored Again Today

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??
