One punch from Sister would send anyone flying.

Belphegor just doesn't want to see a kid upset.

That kid saying he'll hit sister if she don't give him candy looks like he'll have a dark future

Idk, I think Sister punching Belphegor as a running gag is getting kinda old. They're friends now and Belphegor's basically abandoned being evil. And Sister will punch her over the smallest things too. At least reserve it for if she's seriously going back to her evil ways. Not, for example, obviously harmlessly teasing a child.

I think Belphagor might be stronger than the sister, but chooses not to retaliate or attack her. Even when sister was sick she still chose not to attack her, so i think that Belphagor just likes sister and doesn't want to kill her.
