I wanted to know how my readers want the story to develop, so I thought I'd just leave this here for you to comment what you'd like to see in the future.
Harem: Who do you want in the harem?
Time skips: Naturally some time skips will be needed but how far do you want to skip and what would you like to see between each skip (especially during characters growing up)?
World travel(undecided): There's much to explore in the base world but, would you be interested in seeing Cain visit other worlds that exist in the dimensional gap? If so which worlds should he visit?
Other Suggestions: Anything else you might want to see or other categories I should add here?
Complaints: Go on, I can take it.
