Continued shoujo's the way to go, if God permits, UC. heh
To answer anonymous, once I have the plot, I start first with creating characters, their looks, backgrounds, values, habits, struggles. Even explanations as to "Why him? Why is this person so annoying?"
I will try to answer, "Why did Doug use to follow Jesus? Why is Solomon erm...seemingly simple-minded and very trusting? The enthusiasm of a born-again Christian or something more to it?" The fun part I look forward to is seeing how Solomon, Doug and other characters mature and change (for good or worse, who's to know?).
Anyway, once I get a character figured out, then it's, "Erm...where do I put him/her now and How?" I have many ongoing stories going through my head (usually 5 to 6 at one go). I can't think about all of them at the same time(!!) so, I guess it's 1/2 "pull along as the story goes" and 1/2 "I already have something planned." As the story goes, I'll add as I see it fit. For this manga, I already have around 10 characters lined up to be added.
Erm..amidst all my rantings, does this answer the Q?
