Isolated Immortality

Poor American student Ray isn’t very popular. He excels in his grades but is unable to make a single friend and his home situation is rather dangerous. One day, Ray, while trying to help one of the classmates that is so dismissive of him, ends up messing up and getting shot. God, sensing that Ray wants a second chance at life and acknowledging his deed before death as heroic, allows Ray to be reincarnated into a stereotypical swords and magic world that Ray was so charmed by when he first learned to read. God asks Ray what sort of ability he would like to get him started. Ray, still fearing the feeling of death he had just moments before chooses immortality. Just how long will it be until Ray regrets it?
