This story is an alternate version of "A Sound of Thunder" by Ray Bradbury. I was assigned to add a new character into the story, by my English teacher. This is what I came up with. She told me to post it online, so that everyone else can read it. To understand the story, you'll need to read the original short story. Pdf versions can easily be found online. Yes, the character I added has the name Yuki. At the time I wrote this, I was in my Japanese name phase. It's a good thing that ended.
