I can't imagine an arc that lasts nine years, there're probably more arcs after the long one unless Kubo specifically said there were two arcs left and two arcs only. It's nice to know Chapter 478 is the climax of the current arc, I'm looking forward to it and all the revelations it will bring. Another interesting part is that Tsukishima was created many years ago, which supports the idea somebody has been under the influence of BOE for a long time. *fingers crossed*
I think what he means by saying that Tsuki was created long time ago was that he thought about his design a long time ago... not that he knew what he'll be and where he'll use him.
And of course, there's Unohana's former Lieutenant who looks like his copy, lol
About the Jump Festa stuff:
Deathberry has it all :3 and BA like normal ofc :3
Shounen Jump Alpha is doing an interview with Kubo too, full interview is available only to SJ Alpha members though. Here, at least a sneak peek.
Here is the second part of the sneak-peak, I hate living in europe...
Q: After the massive Arrancar arc finished, can you tell us what you were trying to do with the Lost Agent arc that started in volume 49?
Tite Kubo: In the story arc, I was trying to reboot and recreate what I have done in Bleach up until now. In Bleach chapter one, Ichigo gained the power of a Soul Reaper. But now that he has lost his power, Ichigo must get it back. It’s like starting all over. The Lost Agent arc is important because it leads into future chapters. (Note: The next story arc, The Final Chapter: Thousand Years Blood War arc began in this issue!)
