In the vibrant world crafted by Gege Akutami, fans are more than just viewers, they want to shape their own cinematic experience. The latest proof is a massive petition sent to studio MAPPA with over 66,000 signatures. The petition calls for the integration of the song “Tuca Donka” into the legendary “Jackpot” moment of the character Kinji Hakari.
From a TikTok meme to Hakari’s unofficial anthem
The craze started with Kinji Hakari, a third-year student suspended from school with a fierce passion for gambling. Hakari’s Domain Expansion, “Jackpot Doctor,” creates a gambling world modeled after a pachinko machine, with Hakari as the casino owner. If he hits the “Jackpot,” he gains temporary immortality and unlimited healing.
In the manga, Akutami describes that during this moment, music from a fictional film called Admiring You plays. Since no actual melody exists, fans have filled that gap themselves.
Since 2023, fan-made videos on TikTok and YouTube have paired “Tuca Donka” with Hakari’s fight scenes. With its intense, driving bass and wild energy, this track oddly matches Hakari’s style of fighting while dancing, becoming an inseparable aura for the character.
Heavy pressure on MAPPA and copyright challenges
The petition is putting friendly but strong pressure on MAPPA. Fans argue that officially including “Tuca Donka” would be a historic collaboration between the studio and its audience, creating an exciting fourth-wall-breaking effect.
However, the reality is complicated. “Tuca Donka” is a copyrighted work, meaning MAPPA would need to negotiate licensing and pay significant fees. Facing these legal hurdles, many anime forum experts predict MAPPA might opt for a safer route by creating an original soundtrack inspired by Brazilian Phonk to satisfy fans while avoiding legal issues.
Whatever the outcome, this campaign highlights the influential role of Jujutsu Kaisen fans in shaping the future of one of today’s most popular anime.
