Behind the scenes
While not part of the 60 and beyond Fullbottles seen in the on-screen canon, this Fullbottle is clearly derived from Haruto Soma, the eponymous hero of Kamen Rider Fourze. Following the example set in Kamen Rider Ex-Aid: True Ending and the subsequent Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders, the Mahoutsukai Fullbottle would constitute part of the "essence" of Kamen Rider Wizard. The complete Wizard Fullbottle is paired with that of Kamen Rider Fourze in the toyline.
