Requiem In Separation

A recluse NEET female subdued in her own delusional thoughts goes on a spree to create the ultimate fictional story based on her own views where being separated and different is the only way to live. However, in an attempt to do something nice she ends up in a tragic accident only to be "graced" with the ability to travel to another world upon her death, and due to this grace she'd be able to have one ability unique to herself and her views upon arriving in that new world. But its only as she progresses further into her new life does she discover her "grace" wasn't really a blessing.
