I'd honestly been starting to slip off of this series. The second half of season 2 felt surprisingly anticlimactic, and the movie Scarlet Bond did not work for me. Knowing that one of the main threats from that movie was going to be reappearing in this one (wasn't hard to figure out, given the cast list), even if she was one of the more interesting aspects of the movie, was not a good sign, and given that this was a three episode run that basically functioned like a movie, that was another potential strike against it since these self-contained stories hadn't really worked for mealready. Then I watched it, and honestly, it's good to enjoy this series again. Don't get me wrong, it's still got some of the problems with the main series, but it feels really endearing. Maybe that has more to do with resetting things to a point before the major power escalation of S2, but there's just a lot to enjoy here. Sure, threats don't feel particularly threatening again, but the "threat" here is different: major political division and Rimuru's chance to prevent it. The plot is nothing exceptional, but keeping it largely simple (beyond a deeper plot that we've only started to understand even taking the movie into account) is in its favor, making it easily contained to the three episode run. It starts off as an idiot plot (i.e. one where everything could be solved if two people just sat down and talked for a minute), but that conflict gets resolved in a satisfying manner without feeling overbearing (looking at you, Scarlet Bond). It's far from perfect - its villains are two-dimensional, the main cast just exits the plot at a conspicuous juncture, and we never find out what a certain character was after despite being highly advertised. Still, it's nice to see that this series is back to effectively balancing both Rimuru's no-nonsense attitude when it comes to getting things done with his naiveté and otaku nature. It's also nice to not have a bunch of unnecessary fights - what does happen here is well-contained based on the characters and emotions involved, with very little feeling drawn out to an extreme. It feels comfortable in a way I've been sorely missing.

This takes place between Season 1 & Season 2. A 3-episode "arc" where Rimuru tries to resolve a dispute within a kingdom but uncovers a conspiracy. Sound familiar? (Scarlet Bond movie) So it's no secret that Fuze (the author) have been making spin-offs left and right to milk the popularity of the series as much as possible as he's nearing the end of the Light Novel. This is one of those. Story-wise, it's been done before within the series, even down to the tropes and lack of stakes or tension. Honestly, it's just something they put out to tide people over till the next season's release and togive an "early" look at Luminous and Violet for fanservice reasons. Are you missing out on anything important by not watching this? No, but you still might enjoy this if you're one of those people who would consume anything regarding this series.

My appreciation for this side story is influenced by my seeing the theatrical movie, which was also a side story. This ONA and the movie have similar plots points, sickly female royal cursed by a shady court physician and a brotherly rivalry, stands out the most. However, my choice would be this three-episode ONA. It just has better pacing and tighter plotting, without the need to cast cameos from other series regulars who do not have a major role in the story and thus making for a clunky and overdone mess. For Tensura fans, this is something to tide you over waiting for the next full seasonof the main story. Don't expect too much and enjoy the show.

Visions of Coleus is a short story that happens between the first and second season of 'That time I reincarnated as a slime'. It's not crucial to the main story but it does give a bit more information on some elusive characters and explore another nation so it is worth watching in the main series. The story is about Rimuru going to another nation to attempt to gather information about a possible civil war. The story isn't super impressive or anything but it's fun to watch regardless. The characters are mainly just rimuru and and locally relevant characters with actual significant characters occasionally coming up.The characters seem just fine, it's just three episodes and enough information is given to understand the characters but not much more. The animation, voice acting and sound are all fine and are good enough for the story. Overall I'd recommend watching this since it does add to both the worldbuilding and characters in the slime world. It's probably best to watch it between the first and second season but watching it afterward doesn't matter much either.

TLDR : All in all an 8/10 for Slime Isekai lovers ig. I Haven't read the source materials or anything but if you loved/liked the previous seasons of Slime Isekai then you will definitely enjoy these 3 episodes. But the question does rise why they are animating such unrelated filler material type content when they can spend the same resources to just continue the proper main storyline. We get to see Rimuru, soei and benimaru in action and glimpses of Rimuru's wolf Ranga. Good pacing and a more or less well coherent story that spans 3 episodes well. The new characters introduced do seem one dimensionaland not well fleshed but they serve the purpose well for a 3 episode story . One point of concern was that the power scaling was a bit off in my personal opinion with normal looking demon being considered close to that charybdis clamity and rimuru actually having to think twice before going to combat. Also benimaru and soei felt strangely underpowered. Like that OPMCness was a bit lacking.

Story (6): This story takes place between the end of Season 1 and the start of Season 2, or during Rimuru's time as a teacher. I prefer to put this in season 1 when Rimuru becomes a teacher. Well overall the story is okay, so Rimuru was told by Yuki to get information from the kingdom but luckily Rimuru solved the problem. I'm glad if the problem is solved because if it's not finished, the story will go downhill. And this story can also be connected to Slime Datta ken Movie Scarlet Bond at the end credits of episode 3. The conflict here is normal, andthe war is also normal but with this result maybe it can be a heavy conflict maybe in the next story, it could be in the series vision of coleus this is brought up in the next season or the story in the future Characters (7): There are some new characters, there are also characters that are related in previous seasons indirectly (like oh this person is the elder sister or brother of this person). In the Coleus kingdom, two brothers face a conflict of misunderstanding but the misunderstanding is quickly resolved with Rimuru so it seems like the execution is lacking even though Rimuru's plan was like that but I expected more to resolve this misunderstanding. Here the characters are okay, there are new characters like Paul who I think his scenes are lacking even though he is a stupid person but I hope his scenes with Rimuru are more. I think he is just a decoration in this story Visual (8): Visuals and animation are okay and yeah like Seasons and Movie slime datta ken as usual Audio (7): Opening & ending are just normal, voice actors are good, sound effects are good, soundtrack is okay

This side story really cliche. The story is about going into some country and solve its problem. The problem was simple like prevent two good guy turn against each other and defeat the bad guy. The pacing is well-done, however, found annoying with the cliche like bad guy always old people, good guy always young, the two good guys somehow stupid that they didn't know being manipulated until Rimuru helps them, the bad guy also stupid where they should have escape after they found out they do bad things rather than face on with good guys, the bad guy sacrifice his friend for their own powerbut still lose, the true mastermind summoned by the bad guy, however, the bad guy is useless then the mastermind kill the bad guy then mastermind just vanish because not interested, then the country is saved. However, I still gets laugh and entertained little. But really hate with the cliche.
