Synopsis

Set in the gap between the first and second seasons of *That Time I Got Reincarnated as a Slime*, Rimuru heads to the Kingdom of Coleus, only to find the country caught up in a web of hidden schemes.

As tensions and intrigue build behind the scenes, Rimuru is drawn into confronting the conspiracies swirling through Coleus while navigating the dangers that come with them.

Otaku Consensus

Visions of Coleus lands as a competent, compact Slime side story: Atsushi Nakayama’s direction and 8bit’s familiar polish keep the three episodes readable, and its original-story status makes it a safe watch for light-novel readers wary of spoilers. Reception settles around “solid but nonessential,” with fans praising the voice work, magic-action readability, and political framing while repeatedly noting that the pacing and overall production feel below the main Season 1 standard.

Why You Should Watch

Watch Visions of Coleus if you want Slime’s diplomatic, royal-affairs side without committing to a full-cour campaign or risking light-novel spoilers. It scratches the same itch as the quieter nation-management stretches of That Time I Got Reincarnated as a Slime and the policy-table appeal of Log Horizon, but in a brisk three-episode package built around intelligence work, court maneuvering, demons, vampires, magic, and Rimuru’s shapeshifting problem-solving. The appeal is not a major power-level reset or a franchise-defining battle; it is a side dossier that lets 8bit revisit the world between Seasons 1 and 2 with enough comedy and action to keep the politics from becoming dry. If you like Rimuru most when he is reading a room rather than simply overpowering it, this is the target cut.

Key Characters

R
Rimuru Tempest(VA: Miho Okasaki)
Rimuru is at his most franchise-specific here: an absurdly capable isekai lead whose charm comes from combining soft-spoken diplomacy, comic elasticity, and the confidence of someone who can survive the room if negotiations fail.

What Makes It Stand Out

1
The OVA is structurally placed between Season 1 and Season 2, which makes it a rare Slime entry designed to expand the timeline without requiring later light-novel context.
2
It is credited as an original story from Fuse and Taiki Kawakami, giving it source-side legitimacy while avoiding the spoiler problem that often surrounds franchise side entries.
3
8bit handles the animation, keeping the special visually aligned with the main television series rather than feeling like a detached promotional short.
4
The AniList tag profile is unusually politics-heavy for a three-episode isekai special: Royal Affairs is tagged at 90% and Politics at 80%, with Vampires, Demons, Magic, and Shapeshifting all prominent.
5
Its reception data reflects a side-story ceiling rather than a failure: a 7.58 MAL score from over 50,000 votes and a 76/100 AniList score point to broad approval, while reviews consistently frame it as enjoyable but not essential.

Fun Facts & Trivia

Fun fact 1: Visions of Coleus aired all three episodes on November 2, 2023, making it a finished, self-contained mini-series rather than a weekly side arc.
Fun fact 2: The main character design pipeline connects franchise identity across media: Mitz Vah is credited for the original character designs, while Ryouma Ebata handled the anime character designs.
Fun fact 3: Toshizou Nemoto is credited for series composition, a key role for a three-episode project where the story has very little runtime to establish court intrigue, comedy beats, and action payoffs.
Fun fact 4: The art side lists Ayumi Satou as Art Director, with Tomoyasu Fujise and Masahiro Satou on Art Design and Kenichirou Tomiyasu on Concept Art, reflecting a dedicated setting-development team despite the short format.
Fun fact 5: Fan discussion frequently highlights that the special does not spoil the translated light novels, which is one reason it is often recommended as a safe extra for anime-only viewers and source readers alike.
