*panels with markings in the top left corner mean I am certain of the character’s status and other panels without the markings are my assumptions.
Ask me and I’ll respond.
Q: In the new arc, the shinigami will of course be represented, but will other characters from the past also appear?
Kubo: Yes, if the arrancar appear, I think they will stand with the shinigami.
Q: Will there be characters that appear in the role of a friend?
Kubo: Ulquiorra has already turned into ash. Grimmjow might become a friend. Also, what about Harribel, who is still alive? But, I wonder how I’d bring them out of Hueco Mundo. I think Harribel would not leave Hueco Mundo.
Q: Was the idea of arrancars becoming friends in your plans before this break? Or was it just a feeling that they might return?
Kubo: “They might appear.” Or it could be that “they might not appear.” (laughs) Even if they did appear, it wouldn’t be individually, but as a group.
Q: What about Nel?
Kubo: I think I will let Nel appear.
Q: I’d really like to see her interactions with Kon.
Kubo: Kon did not appear in the Lost Agent arc. But to tell the truth, he has rarely appeared since the end of the Soul Society arc, roughly five years ago. (laugh) People who only recently started reading might not know that he exists. (laugh)
Q: It can’t be that you’ve forgotten him?Kubo: (laugh)
