From the Jujutsu Kaisen The Real 4D attraction at USJ Universal Studios Japan, this is a voice keychain in the style of a pendant featuring a photo of Itadori and Takada-chan, which Todo made and kept. It's a new, unopened item. It's a newly released product. Immediate purchase is possible without comments. It plays Takada-chan's song, "Saikyou Chou JUMPIN!", and evokes memories that never existed with his brother.
