Rebirth in One Piece as Deputy Captain - Chapter 449

Eira thought there could be nothing worse than being abducted by she-wolf traffickers, abused, tormented, and ultimately sold off to five powerful Alphas as nothing more than a breeder.She was wrong. The worst was yet to come.She was sold to the same five alphas who had ruined her life and were the reason for every torment she had gone through over the past six years.The Alphas were just as stunned to see her, yet they had no choice but to accept her for the sake of their pack’s future. Because pureblood she-wolves were rare, nearly extinct. Only they could bear the offspring of powerful Alphas, and ensure the survival and strength of the next generation.She hated them with every broken piece of her soul. And they hated her in return.The hatred was mutual. So what now?Eira made a silent vow. She will make them feel every brutal torment she had suffered.

And when she was no longer of use… they will kill her.But what will they do when the mysteries from the past start to uncover and lines of hatred start to fade into something else?Was it too late to regret?

Fang He is a person who is very compatible with mutant animals, but it is also because of his ability that he has changed from the strongest to the stupidest.
Fang He, who was reborn, said, “Hmph, this time…”
