The tribute paid to Uzumaki was duly authorized by the author of the work!
With the release of the 16th volume of the original manga Jujutsu Kaisen, by Gege Akutami, a leak brought, in a forum, information about the homage that the mangaka paid to the manga Uzumaki by Junji Itou.
According to Leak, the extra page of the latest volume released from the work brought an image that reveals the reference Akutami used from Naruto.
‘Maximum: Uzumaki’, which appeared from ‘Volume 0’ of the work, was inspired by the manga series ‘Uzumaki’ by Junji Itou. Gege mentioned that he wanted to draw Uzumaki on two occasions, once for publication in Weekly Shonen Jump and another in the compiled volume, but revealed that he couldn’t make a ‘Maximum: Uzumaki’ as scary as the original. Gege also noted that he had a clear pattern for differentiating a parody from a tribute. He thanked many authors, including Junji Itou, who gave him permission to use their intellectual property, although sometimes Gege Akutami and Weekly Shonen Jump were slow to notify, mainly due to the intense pace of publication and tight schedules.
As of the end of May this year, Jujutsu Kaisen has reached 50 million copies in circulation among its 15 compilation volumes published so far. This value takes into account the physical and digital copies of all volumes sold.
