Gates of Hell

Nate Trenton is a 16-year-old boy living in Portland, Maine. On his way home from school one day, he falls asleep at a park. When he wakes up it's pitch black and he has to walk home in the dark. As he's walking home he sees a young woman with white hair and red eyes. When he approaches her, he's sent to an odd, hellish world that he must escape to return to his world.

He quickly meets a young demon girl named Delia, and a demon boy named Michl who help him traverse through their world so that Nate can return home. Along his way, he encounters new friends and foes and has to fight demons that get in the way of his escape. He quickly comes to learn that escaping this world and returning home won't be as easy as he first thought.
