"An everyday man gets thrown into the world of twilight thousands of years before the start of the plot. With immortality and incredible abilities. How will this man's presence change the outcome of the original story?" [ this is a slow-burn fanfiction; the MC is just trying to experience life and enjoy it, not to take over the world and rule from the shadows.] I do not own twilight or the characters of the twilight world, all that belongs to me are my own characters.
I like your Story and your style of writing, but what I really dislike is the break up of Bulma and Kalan. I don't want Trunks. Bulma and Kalan was a shipment which brought Bulma in a little different light except of the Anime/Manga. I liked this Bulma. I think you should let them get back together. In my opinion is this shipment really good and worth to continue. Although it would break the common knowledge og Dragonball and it would make your FanFiction a really good FanFiction. But except the break up of Kalan and Bulma, I like your story very much an I hope it goes on.
