Universal Studios Japan is leaning hard into the memes, officially releasing a Jujutsu Kaisen sound keychain based on Aoi Todo's infamous locket. Yes, it actually opens up to reveal photos of Yuji Itadori and Todo's favorite pop idol, Takada-chan, nestled right inside.
This is a hilarious nod to one of the anime's best running jokes—Todo's utterly intense obsession with Takada-chan and his instant, chaotic "brotherhood" with Yuji.
To top it off, the keychain features a built-in sound button that plays "Saikocho JUMPING!", the signature idol theme song Todo constantly hypes up in the series.
The collectible went completely viral on X after user @dragon_chi_gyu_ posted a clip of it, racking up hundreds of thousands of views. Fans are absolutely loving the fact that such a deep-cut inside joke was turned into official theme park merchandise.
It just goes to show that Jujutsu Kaisen really knows how to deliver the absolute best kind of fan service, even for its most random moments.
