Chasing Family: Reborn an Ability Thief

Molly didn't have to be born into a fantasy world in order to experience magic. When she finally died an old lady, all of her children, nieces, nephews, and grandchildren had various magical abilities, though she didn't have any herself. Reborn into another world, she suddenly had magic, but it wasn't fun and games. In order to use her magic, she had to provoke people with abilities into killing her. Over and over again.

On top of that, she was stuck between the humans and demons in their never-ending war, and the mysterious god who had reincarnated her told her that her family in the first world was going to give birth to a villain. So now she had to navigate the war, a narcissistic hero, an angry prince, and find a way back to the first world to find out which of her numerous descendants was going to grow up evil.

But at least unlike her first life, this time she had magic. Even if it might kill her.
