Tensei Shitara Slime Datta Ken: Guren no Kizuna-hen

This one-chapter manga was released in 2022 as a theatrical bonus for attendees of the Tensei Shitara Slime Datta Ken: Guren no Kizuna-hen film. As an original prequel rather than an adaptation, it holds a distinct place among the franchise's printed works: it is less a full serialized story than a keepsake that rewards readers who saw the movie in theaters. Its finished, single-volume format makes it a compact collectible, and its scarcity outside that original giveaway context gives it special appeal for completists and fans of theatrical ephemera.

In experience, the manga offers a quick burst of Action, Adventure, and Fantasy set in the same world of Demons and Isekai. Because it is only one chapter, it reads more like a vignette or an extra scene than a self-contained epic. The pleasure comes from returning to a familiar setting and tone in a brief, focused format, with the original story material allowing it to add a small piece of background without retelling the film.

Approachability depends on familiarity. Dedicated followers of the series will get the most from it, since it assumes prior knowledge of the setting. Readers who have not encountered the franchise may find it too slight as an introduction, especially with no current official edition verified. It is best approached as a companion to the film and a curiosity for collectors, not as a standalone entry point into the larger saga.

Tensei Shitara Slime Datta Ken: Guren no Kizuna-hen is a single-chapter, single-volume manga released in 2022, cataloged under the Japanese title 転生したらスライムだった件 紅蓮の絆編. The saved record marks it as a finished individual work whose source material is listed as original rather than as an adaptation of another medium, and it carries the genres Action, Adventure, and Fantasy with Demons and Isekai as themes.

The AniList entry credited in the record describes this manga as a prequel story that was given to filmgoers attending the movie of the same name. Its start date and end date both fall on November 25, 2022, which points to a single-day publication tied to that theatrical distribution. There is no serialization run, episode count, or runtime recorded for the title, matching its one-chapter, one-volume scope.

The supplied record contains no author, illustrator, or publisher credits, so this entry does not attribute the work to a named creator, studio, or magazine. It also notes that no current official English-language edition has been verified. This page covers only the 2022 one-shot manga and does not describe the film or the wider franchise to which it is linked.

This entry belongs to the Tensei Shitara Slime Datta Ken franchise, the property usually rendered in English as That Time I Got Reincarnated as a Slime. That franchise began as a light novel series and grew outward into a long-running manga adaptation, television anime seasons, and theatrical films. Within that spread, Guren no Kizuna-hen is not the starting point and not a mainline continuation. It is a single-chapter manga released in 2022 alongside the franchise's feature film, sharing the film's title and its Scarlet Bond English rendering.

This manga was produced as a prequel and distributed to people attending the movie in theaters, which makes it a companion piece to that film rather than an independent series. Readership context matters here: the main manga volumes and the anime adaptations carry the ongoing storyline, while this one-shot sits beside them as a promotional side story.

Because it was a theatrical handout, it has never had the same wide circulation as the core volumes, and no current official English edition has been verified. Treat it as a curiosity for franchise completists, an alternate-format footnote rather than a required stop in the reading order.
