Hard to say, because the story sort of forms as I go along. I have a general plan, but I know things will turn out a bit differently - they just always do when I write. It'll be one chapter first that leads up to choosing a partner. Then one chapter of preparing for and wrestling each match in the tournament - likely three in total per route. Then a climax of at the end, with possibly an extra match there too. So... we're probably looking at 14-15 chapters if I don't pack some of these into larger ones - or get writing help.
