Ahahahaha, I'm looking up all the old Kubo quotes, and theres some real doozies in there.
@Kubo:
And there're also some things I take from the 7 deadly sins. Like the one now, who are the espadas? Barragan, Aroniero's "Gluttoneria", Zael Apollo's "Fornicaras", and the same applies for Yammi. Those are the early days of "Espada". In the early stages of Espada, there were only 7 people. It's "Espada" with 7 swords but, it increased gradually and became the "Espada" of now. That's why there are some more of the 7 sins I haven't used. While drawing Aaroniero, he had the power "to eat" so I've got the "Gluttony" from the 7 deadly sins. But I also didn't want to just get stuck with the 7 sins. That's why there are times I don't use them on purpose and leave them be. Like for the early days Espada that survived (laugh).
Translation: Themes are something you adhere to, until you don't.

A personal fave:
PWCW: Now that Bleach has been going on for a bit, how do you keep the adventure and the story fresh?
TK: I think it maintains a freshness because when I create manga, I don’t think about what’s going to happen—I just come up with an idea and let it flow. It’s a weekly installment, so I have a very short time to create manga, but the good thing is that because it’s short, I can come up with the idea and start creating it.
