Tensei Shitara Slime Datta Ken: Guren no Kizuna-hen

Tensei Shitara Slime Datta Ken: Guren no Kizuna-hen, known internationally as That Time I Got Reincarnated as a Slime the Movie: Scarlet Bond, was produced as a theatrical expansion of the globally popular light novel and anime series written by Fuse. The film, which premiered in late 2022, was designed to bridge gaps in the existing narrative while introducing an original storyline centered on the neighboring kingdom of Raja. The production was helmed by director Yasuhito Kikuchi at Eight Bit, the studio responsible for the television adaptation, aiming to translate the series' high-fantasy world-building and character dynamics to a cinematic scale.

The film's visual identity remains deeply rooted in the character designs established by Mitz Vah, the light novel’s illustrator, whose aesthetic defined the series' look. The story focuses on a new character named Hiiro, a survivor of the Ogre village, integrating seamlessly into the established power structures of Rimuru Tempest's nation. Upon release, the film was received as a respectful addition to the canon, praised by fans for maintaining the light-hearted yet action-oriented balance that has kept the broader franchise at the forefront of the isekai genre for years.
