Rimuru Tempest built a kingdom out of monsters, humans and everything in between, and "Scarlet Bond" sends him chasing a threat that predates all of it.

What is That Time I Got Reincarnated as a Slime the Movie: Scarlet Bond about?

The 2022 feature sends Rimuru Tempest, the slime-turned-Demon-Lord who leads the nation of Tempest, into the small western country of Raja, where a hidden power tied to its Queen has fueled years of intrigue. His path crosses with Hiiro, one of the last survivors of the Ogre race, and the two are pulled into a conflict that neither the Tempest court nor Raja's ruling circle fully understands. New faces join the established cast as old alliances are tested and new ones are forged under pressure.

About the cast

The Japanese voice cast is led by Miho Okasaki, Makoto Furukawa, Megumi Toyoguchi, Tomoaki Maeno, Sayaka Senbongi, Mao Ichimichi, Takuya Eguchi and Hochu Otsuka, largely the same ensemble that has carried the television series since it began. Returning voices matter in a franchise built on an unusually large cast of named characters, and familiarity here lets the film move quickly without re-introducing who everyone is.

Context & significance

Yasuhito Kikuchi directs, extending a franchise that has grown from a web novel into manga, a long-running anime series and now feature films, one of the more durable isekai properties of the last several years. Running 108 minutes, "Scarlet Bond" is built as a stand-alone adventure rather than a simple clip-show sequel, giving newcomers a workable entry point while rewarding viewers who already know Rimuru's court. Its adventure-fantasy core stays close to what made the television series popular: large-scale worldbuilding paired with a protagonist who solves problems through negotiation as often as force.
