Zach died in a train crash and was reborn in a world he’d only read in books and seen in movies. The same world turned out to be less fiction and more hard reality than even his past boring life.

It's a story about a man, well it's cliche, he died and reincarnated. His cheat was Kamiya Yato's ability. You didn't know who Kamiya Yato was? Hmmm........ He was the protagonist from a story called "Class ga Isekai Shoukan sareta Naka Ore dake Nokotta n desu ga", but our MC not reincarnated into Kamiya Yato's world. Hmm? Then what world?? Well, just read the story, you will know yourself....hehehe But,, WARNING BEFORE YOU CONTINUE AND READ THE STORY!!! English wasn't my native language, so my English could be said really poor and bad. That's why, I think the story would be a bit unpleasant to read because of that,, V(^_^) It was a Fan-fiction, so all credit wasn't mine. All of it was owned by the original story and its author...
