Without revealing too many plot details, the trailer successfully teases major developments and new threats that Rimuru Tempest will face as the story continues beyond the events of the recent movie.

Key theories and concerns include:

Tensei Slime Season 4 Confirmed to Continue After the Second Movie
As confirmed by Crunchyroll and FandomWire, the new season is set after the events of the second movie. That means the world-building and new characters introduced in Tears of the Blue Sea may appear again in some form, or influence story directions indirectly.
This layered approach helps bridge fans who follow both the movie and the anime, creating a tighter narrative universe.
The second movie lays emotional groundwork, Season 4 may explore its aftermath politically and socially in Tempest.
