In a 2009 interview, Kubo and Masashi Kudō discussed the upcoming Zanpakutō: The Alternate Tale, with Kubo wishing that he could draw the events into the manga. Kubo also revealed that his art style varies in the production of the work and only became cemented after the airing of the anime. He acknowledges his art style has changed as a result of his work and gave an example that he no longer draws hair growing from behind the ears of characters.
