I was reading a timetraveling fic and I was wondering what would happen if something bad were to happen and the only way to fix it would be to go farther back in time. Kagome would have to find a way to control the well. The idea of the butterfly effect would be that even the smallest change she makes would alter the outcome so it would take a lot of trial and error no?

Optional:
Going too far back in time
Lemon
Timeline of the story

Just an idea.
