Reborn as a Mecha Girl After Being Betrayed: Madam, Please Have Some Self-Respect

After being betrayed and left gravely wounded on the brink of death, she was saved by her own mechanical girl. Having become a young woman, she met a beautiful lady who was willing to take her in. The girl swore that those who betrayed her would have to die!

But before that, she needed a new name.

Aida: "From now on, your name is Mero. You're a maid of the Esbel family, and in addition to your regular duties, you'll also be responsible for protecting my daughter."

Mero: "I understand, Madam."

Aida: "Good. Now... come inside with me."

Mero: "Huh???"
