After Rebirth, I Stole My Sister's Bionic Human

And Julia, my sister, got two replicants from our father, a scientist. I took the one with the least ability.

Julia openly made fun of me, saying, "It's just a pile of junk. Only you, who likes collecting junk, would like it."

I secretly made fun of her for being a great fool.

In my past life, I chose the replicant I served with all my heart.

In this life, I chose to let go of him.

"I will let my sister enjoy the joy of being servile."
