School of elements

( this is an original story, derived from my own imagination and heart)
Just how much can a Pearson take, between college, taking care of little sisters, and protecting the entire universe from some evil dude in a Fedora,
Andrew Pierce is a freshman in college who has two little sisters to take care of, and lives in a world of magic and technology.
You think school is hard, he has to deal with an apocalypse and pass with straight As.
Its gonna be a wild ride.
