The practice of disseminating leaks on Twitter by manga leakers before the publication of a manga chapter may be coming to an end since Japanese police have begun pursuing those responsible for posting leaks online. This week, after the authorities verified their identities and actions, two Shonen Jump manga leakers were taken into custody in Japan.

According to information provided by the authorities, these two people released pictures of editions of Shonen Jump magazine in March 2023, and they were later imprisoned for it. Sharing these “leaks” is susceptible to jail time and is regarded as a copyright law infringement of intellectual property. Prominent leakers are now pledging to take more extreme measures or to stop their activities completely in response.
Leaks onOne Piece, Jujutsu Kaisen, My Hero Academia, Blue Lock, and other series were shared by the apprehended leaker. This further detail features the indication that these individuals purchased magazine issues before their date of release. The operation is being thoroughly investigated by the police, who have reason to believe that some more people were involved.
