That Strange Pain

When Tomomi, a 17 year old high school student, ends up gaining powers he never thought possible, he's more confused than shocked. He then is attacked by some people who say he's "DIO's successor", whatever that means. Learning more about this strange "Stand" is his top priority, but he's not against making some friends along the way, and starts questioning what's already happened.
Who's Jotaro Kujo? What's a DIO?
He starts this journey alone with questions, and ends it with friends and answers.
