Slime Season 4 Part 3 Set for July 2027, Clayman Spinoff in April
The third part of That Time I Got Reincarnated as a Slime Season 4 is scheduled for July 2027, with an anime based on the Clayman spinoff manga arriving in April.
The third part of That Time I Got Reincarnated as a Slime Season 4 is set to arrive in July 2027, and an anime adaptation of the franchise's Clayman spinoff will land in April. The two projects give the series a two-stage rollout, with the spinoff arriving first and the main season continuing several months later.
What was announced
Two things, and they are worth keeping separate. The first is the July 2027 date for part three of Season 4 of the main anime. The second is an anime based on the Clayman spinoff, scheduled for April.
That spinoff has manga roots. Wataru Kajika's spinoff manga about Clayman debuted in April 2022, which means the source material has had a run of several years behind it before the anime arrives. Clayman is a name that carries weight for anyone who has followed the main series through the Walpurgis arc, so an adaptation that turns the attention toward him is a natural place for the franchise to expand rather than a random side project.
The staggered scheduling is the detail most worth noting. April for the spinoff, July 2027 for the continuation of Season 4. Anyone tracking the franchise has two separate things to put in the calendar, not one.
What has not been announced
A great deal, and it is important to be precise here rather than vague. No staff credits have been given for either project: no director, no series composition writer, no character designer, no animation studio. This is not a case of names being withheld until later. Nothing on the production side was named at all.
The same applies to cast. No voice actors have been announced for the Clayman spinoff anime, and no cast information was given for part three of Season 4. There is no theme song artist, no episode count, and no confirmation of how the spinoff will be distributed or how long it will run.
On dates, there is a difference between the two announcements. The main series has a month and a year: July 2027. The Clayman anime has April, without a year stated alongside it in what was announced. That is the level of detail currently available, and anything more specific would be guesswork.
Why it matters
A franchise that can support both a continuing main season and a separate spinoff anime is a franchise operating at a certain scale, and the April and July 2027 slots show a plan that runs across more than one broadcast season. The Clayman manga launching in April 2022 and reaching anime form now follows a familiar shape for long-running properties: a side story is given room to build on the page first, then adapted once it has substance behind it.
For viewers, the practical effect is that the wait between parts of Season 4 is not empty. The spinoff arrives in April, ahead of the July 2027 continuation, which keeps the property in rotation rather than leaving a long gap with nothing on screen.
Until staff and cast are revealed, the shape of both projects remains open. What is fixed is the timing: Clayman in April, Season 4 part three in July 2027.
