This is reasonably deranged and unhinged, I like it. Unfortunately, it would be hard to maintain this pace without completely butchering the story.
I will continue to watch it to see where it goes.
what do you mean you cant make a little sister with effort? just poke holes into your dads condom the next time he comes home and get both your parents drunk, in a little over 9 months you got yourself a little sister! how simple is that!
Isn't the solution staring us in the face? Change the witch girl's little sister to be the MC's little sister.
Sure, it would still be fucked up in terms of the little sister's free will or whatever, but it's better than killing her.
That was oddly refreshing and entertaining. It's kind of... Unironically peak?
All the characters are so well-developed already. This will be a fun read if it doesn't fall off.
