Shueisha’s Shonen Jump+ editorial department is ending its outsourcing arrangement with Mix Green, the editorial company founded by former Chainsaw Man editor Shihei Lin. The Jump+ staff announced the decision on Wednesday, adding that any titles Lin had been handling for the platform will keep serialising under a new editorial structure.
Lin responded the same day on X, saying Mix Green has signed direct contracts for four of the series it edits and will therefore continue to oversee them: Tatsuya Endō’s SPY×FAMILY, Yukinobu Tatsu’s Dandadan, Tohru Kuramori’s Centuria, and Hakuri’s WITCHRIV. In other words, the split ends Mix Green’s editorial services for Jump+ as a platform, but it does not take the editor away from the individual manga he works on.
What Shonen Jump+ said
The editorial department’s statement is the primary source here, and it is short. It announced the termination of the outsourcing of services to Mix Green, and it stressed that series Lin had been working on for Jump+ would continue serialisation “under a new structure” — language that leaves the day-to-day editorial chain open, but confirms no title was cancelled by the change.
Lin’s own statement fills in the other half of the picture. The four titles named by Lin are the ones affected by the platform-level arrangement and the ones he says he will keep editing. That distinction matters: a reader seeing “Jump+ cuts ties with editor” could reasonably assume his biggest books were being reassigned, and both sides are signalling that is not what is happening — at least not for SPY×FAMILY, Dandadan, Centuria and WITCHRIV.
Who is Shihei Lin
Lin joined Shueisha as an editor in 2006 and worked at the publisher until he left in August 2022. He continued working with the artists he edited on a freelance basis, and during his time at the company he worked on titles including Chainsaw Man, SPY×FAMILY and Dandadan — three of the most commercially successful series to come out of Shueisha’s digital-first and premium manga push over the past decade.
His departure from Shueisha in 2022 made him one of the most closely followed freelance editors in the industry, largely because the books associated with him kept performing. Chainsaw Man, Tatsuki Fujimoto’s series, has grown into a flagship franchise with an anime adaptation, an ongoing manga and a steady stream of tie-ins. SPY×FAMILY and Dandadan, both serialised on Jump+, are anchors of the platform’s international catalogue.
Mix Green and its manga platform
Mix Green is Lin’s own company, and it is not only an editorial shop. Lin launched the company’s new manga platform on April 17, and the platform began accepting manga submissions from artists at that time. That makes the company a publisher-adjacent venture as well as a service provider, which is the context behind a Jump+ announcement framed around “outsourcing” rather than around any single contract.
Running an independent platform while editing flagship titles for a major publisher’s app is an unusual position, and it is easy to see why both sides eventually had to define where the line sits. The four direct contracts Lin described on X look like exactly that line being drawn in public.
Why it matters
For readers, the practical takeaway is that the four named series keep the editorial oversight they have had, and Jump+ titles in general continue rather than pause. The story is a business one — how a major digital platform sources editorial work, and how an independent company that both edits and recruits manga fits alongside it.
It also lands at a busy moment for Jump+ and its parent’s digital operations. Shueisha’s global MANGA Plus service is adding the Digimon Eggs manga as a simulpub in the same week, a reminder of how much of the publisher’s growth now runs through its digital side. And the mix of creators involved keeps the wider Fujimoto orbit in the news, from the creator’s own Eisner-season recognition for Tatsuki Fujimoto 17-26 to the many editors and artists who came up through his books.
Neither Shueisha nor Mix Green has detailed the new editorial structure for every Jump+ title Lin touched, so the specifics of who picks up what are still open. We will update this story if either side publishes more.
