That Time I Got Reincarnated as a Slime the Movie: Scarlet Bond (2022)

Scarlet Bond captures what makes Slime so easy to love: a bright, buoyant fantasy world where kindness and power aren’t opposites, and where a single new friendship can shake an entire kingdom’s fate. The movie looks terrific—crisp action, colorful magic, and that satisfying sense of scale when Rimuru and company step into a new land—while the music and theme song keep the adventure humming with momentum. Its secret weapon is Hiiro, an ogre survivor whose rough-edged emotions give the story real heat, letting the film balance cozy camaraderie with bursts of demon-cursed danger and PG-13 intensity. If you’re brand-new to the series, you may miss a little context around the larger cast, but the film’s self-contained stakes and warm-hearted vibe make it an inviting, crowd-pleasing ride for anyone on the fence.

Scarlet Bond is clearly trying to give Slime fans a self-contained side adventure with a new kingdom, a tragic new ally, and a “bonds tested” emotional hook, plus the comfort of seeing Rimuru and the Tempest crew show up to fix problems. The snag is that the story piles on conspiracies, curses, and new faces in a way that can feel busy rather than gripping, and Rimuru’s overwhelming power often drains tension from conflicts that should land harder. If you’re new to the series or hoping for a tight fantasy film that stands perfectly on its own, the pacing and predictability may test your patience. Still, the animation is solid, the core friendship dynamic has warmth, and longtime viewers will likely enjoy the familiar voices and fan-service-y moments even when the plot wobbles.
