Production Development On September 7, 2023, Tomorrow Studios CEO Marty Adelstein revealed that the scripts for the second season were ready but filming could not begin until the SAG-AFTRA strike was resolved. Tomorrow Studios president Becky Clements stated that once they could begin filming, they expected the season would premiere approximately 12–18 months later. Netflix did not formally announce that the series was renewed for a second season until September 14. Clements commented that they've had "thorough conversations" on the second season with Netflix, Shueisha and Oda and "less extensive conversations" on seasons three to six.
