@The:
You probably got it from one of the many interviews he's done. I know typing in Kubo Interviews in the google search will give a link for the Bleach Asylum page with all the various interviews. I don't remember which it was, but I believe it was one of the earlier interviews he said that. Another interview said he doesn't plan stuff out, and rereads his work at times when he runs out of ideas. Here is a link to all the interviews if you are interested.
Well, that explains a lot of things and unanswered anomalies on Bleach.
Make me wonder, anyone know how many people is working on Bleach?
If i sit in kubo's chair, i'll definitely hire a writer/story teller, a good one on that especially.
Kubo can design all the characters, think im ok with most of them anyway.
And an extra artist for background drawing and scenery, but eh, thats not a must.
This week chapter is ok, will be better if i know what the heck is that hot bath owner doing,
And a lot better if i dont read fake karakura town arc yet.
Looking forward for that badass zanpakuto maker, he sure got the confidence. Hope its not all empty hype.
