I Decided To Raise My Nephew Who’s Going to Become A Villain

I think my nephew is the real villain. My nephew grew up unloved and neglected, and he will destroy half of the world. I couldn’t gamble our future, along with the mansion residents, on a fifty-fifty chance.
“I will take him with me.”
I decided to sacrifice myself to raise my nephew.

“Pecky!”
Pecky toddled over to me and hugged me tightly. Despite my concerns that he might grow horns on his head, the child grew up brave and kind, making my worries seem insignificant.
Instead of destroying the world, his loveliness alone might save it.
“Lucy, I love you!”
I’m a little worried that he loves me too much and won’t let go, but he’ll improve as he grows!
