When asked whom he would like to see fight each other from his popular manga Bleach, Kubo-sensei said either Shunsui and Ukitake or Ichigo and Kaien, but that the latter who be impossible.
Kubo-sensei: I never imagined when I started writing Bleach that it would eventually be published in the U.S., so I'm really glad that American readers have taken to it and enjoyed my work. Please continue to support Bleach. I've also been told that I should visit America someday.
Kubo-sensei: (talking about his hit manga Bleach) I'm the type who worries about the difference between the season in the story and season in reality. This series [Bleach] started in the summer [for the manga version]. At that time, the season in the story was the month of May. That difference has always weighed on my mind. With this volume [3], the main character Ichigo's introduction ends at last. The stage is June. Unexpectedly nice timing. If you can, please read it [volume 3 of the manga] on a rainy evening.
