Overview

That Time I Got Reincarnated as a Slime: Visions of Coleus is a three-episode OVA that carves out a compact, self-contained mystery within the larger TenSura world. Its appeal lies in how it leans into political scheming, succession disputes, and supernatural maneuverings rather than pure combat, giving fans of the franchise a concentrated dose of the diplomacy and worldbuilding that define its best arcs. The short runtime makes it an easy entry point for viewers curious about the series' quieter strengths, though its references to established characters and factions will land most strongly with those already familiar with Rimuru's journey.

What this OVA offers is a brisk, atmospheric detour that mixes fantasy adventure with conspiracy and vampire lore. The three-episode structure keeps the stakes focused and the pacing tight, making it a satisfying watch for anyone who enjoys intrigue in a magical setting. Its English dub and streaming availability on multiple platforms also lower the barrier for viewers who prefer dubbed anime or want a quick, low-commitment sample of the TenSura universe.

Because it is a side story rather than a mainline season, Visions of Coleus is best approached as a supplemental piece. It does not require deep franchise knowledge to follow the central mystery, but longtime viewers will catch the nods to ongoing themes like economics, demon politics, and shapeshifting. For those who appreciate anime that treats governance and negotiation as dramatic fuel, this OVA is a worthwhile, tightly wound addition.

Synopsis

Visions of Coleus is a three-episode original video animation set within the world of That Time I Got Reincarnated as a Slime. Rimuru Tempest has nearly finished his stint as an instructor to the children of the Kingdom of Engrassia, and with that chapter winding down he is ready to move on to whatever comes next. Before he can, Yuuki, the Grandmaster of the Free Union, hands him a new assignment that pulls him away from the classroom and into unfamiliar political territory.

The task concerns the Kingdom of Coleus, a small nation wedged between Engrassia and the Holy Empire of Lubelius. A struggle over who will inherit the throne has left the court tense, and Yuuki wants a reliable outsider to learn what is really driving the dispute. Rimuru agrees to go undercover, adopting the name Satoru so he can move through Coleus without drawing attention to his true identity or his considerable power.

What he finds is a country where the succession fight is only the surface layer of the trouble. Demons and vampires are quietly pulling strings behind the scenes, and the rival claimants and their supporters each have their own reasons for wanting control. Rimuru must work out who is scheming against whom and keep the situation from spiraling out of hand, all while maintaining his cover as an ordinary visitor.

Production Background

That Time I Got Reincarnated as a Slime: Visions of Coleus is a three episode original video animation released in 2023, with each installment running roughly 24 minutes. The record files it as an OVA, placing it apart from the television seasons, theatrical films, and shorter OAD entries that make up the wider TenSura anime line. Its source material is catalogued as Other.

The OVA follows Rimuru as he infiltrates the Kingdom of Coleus under the alias Satoru, sent by Yuuki of the Free Union to investigate a contested royal succession in a nation positioned between the Kingdom of Engrassia and the Holy Empire of Lubelius. The assignment widens into a tangle of political maneuvering involving demons and vampires. The story is set as Rimuru's stint teaching children in Engrassia is drawing to a close.

An English dub was produced, and the OVA has been carried on Crunchyroll, Netflix, and YouTube, giving it broader availability than a disc-only side story would normally receive. The anime adaptation of the franchise is produced by Eight Bit, and this three part entry sits within that ongoing animation line and its franchise hub rather than functioning as a standalone property.

Franchise Context

That Time I Got Reincarnated as a Slime: Visions of Coleus is a three-episode OVA from 2023 within the larger TenSura franchise. It is not the starting point of the series and not a reboot or alternate continuity. Instead, it belongs to the animated branch that includes the television seasons, other OVAs, and theatrical films, as grouped on the official franchise portal. The entry exists as an individual side-story release rather than a replacement for the main storyline.

Because it is an OVA, Visions of Coleus sits apart from the numbered television seasons while still sharing the franchise's characters, world, and continuity. It is a continuation and supplementary anime entry, assuming some familiarity with Rimuru's story. A viewer coming from the main anime can place it alongside other TenSura animated works, but this page treats it as one installment rather than the whole franchise. The franchise itself began with Fuse's light novel series and grew through Eight Bit's television anime, multiple OVAs, and films.

Where This Fits in That Time I Got Reincarnated as a Slime

A spoiler-light guide to where this exact work fits within the broader That Time I Got Reincarnated as a Slime franchise.

  1. Step 1
    Start with the main television anime and watch through the point where Rimuru finishes his teaching duties in the Kingdom of Engrassia, since this OVA opens just as that chapter of his life is closing.
  2. Step 2
    Treat this three-episode OVA as an optional side story rather than a required stop, because it is a self-contained detour into the Kingdom of Coleus that the main television storyline does not depend on.
  3. Step 3
    Watch it here if you want the extra context on the Coleus succession struggle and the demon and vampire scheming around it, then continue with the remaining television seasons and theatrical films in release order.

Franchise Path

  1. Start with the main That Time I Got Reincarnated as a Slime TV anime through Rimuru's Engrassia teaching arc, since this OVA opens as that chapter closes.
  2. Place Visions of Coleus as an optional three-episode side story within the TenSura anime line, then continue with the remaining TV seasons and films in release order.
