This is a show that you must have seen somewhere over the years. It’s pretty popular and there was always advertising for it. The idea of being transformed into a Slime when entering a fantasy world is pretty interesting. I would argue that the show cheats on the premise later on by including a human form but…..it’s good because honestly the human form is way better. I’ll talk about that more in a minute. The show has its ups and downs for sure, but I would say this is a pretty good season 1 to the show. It develops the cast and gets us some good action scenes. I see a pretty bright future for the title as long as it doesn’t get too cheeky with fanservice. If it keeps going at its present rate I’d say the pros will continue to outweigh the cons.
The show starts with an average guy getting ready for another average day at work. He’s content with his life but at the same time everything just feels so ordinary. Is this really all that there is to life? One day though he gets stabbed and ends up dying. He is then reawakened as a slime with a ton of excellent abilities. He is effectively impervious to damage and most elements while also keeping a good amount of strength and speed. Most importantly, he now has the ability to absorb other creatures and gain their abilities. That’s a pretty good deal eh? Before long he ends up helping out a village and quickly becomes the chief. He is now the head of the Rimiru Tempest alliance. His human name was something else but as a slime he will be known as Rimiru. Together with the villagers he will make the world a better place and fighting is only done as a last resort.
That’s a super loose premise but it’s in part because the series has several little arcs going on. For the most part Rimiru hands out in the village with the goblins, orcs, trolls, and other magical allies that are around him. Each arc typically expands his life of allies as well as his territory as more people join the alliance. Rimiru’s abilities are so vast that it makes sense to join him because if you don’t then you’re probably going to get crushed. The show has a pretty fun atmosphere about it. The fantasy world is well created and it’s vast enough where you can already see how countless stories can be placed in this world. You’ve got the demon lords, human kingdoms, and a bunch of other elements that season 2 will probably follow up on.
There’s a dragon named Veldora who appears in the first episode and hasn’t really had a chance to pop up since then. Rimiru absorbed him so you get the feeling that he should be able to spit the guy back out as his abilities improved but maybe Rimiru just hasn’t thought of it yet? I’d assume there’s a better reason than that of course but having Veldora has helped Rimuru out in quite a few battles thanks to the flame immunity so that part’s already been paying off quite nicely.
The first arc I’d say is basically the origin stories with Rimiru taking down some Direwolves and helping out a bunch of Dwarves when they are given impossible orders. This leads to both factions joining up with Rimiru and starting the basis for the village. The Direwolves part was a bit of a rough start to the show as I would consider it to be the weakest story. There is quite a bit of animal violence there as Rimiru takes the wolves down. He doesn’t destroy all of them at least. Meanwhile the leader becomes a supporting character.
Ranga is a powerful Direwolf whose abilities are fairly relevant even by the end of season 1. The ability to hide in shadows and cast powerful bolts of lightning definitely can’t be underestimated. He’s quite loyal to Rimiru at all times and is just someone you can count on. Most of the Dwarves aren’t all that notable but Kaijin is definitely the main one. He has some ties to the main human kingdom so I imagine that will keep him important for some time. The fact that he is able to craft materials really well and build just about anything is also handy. The guy’s just very versatile and a reasonable character.
I suppose now’s a good time to talk about Rimiru. Well, he’s not exactly the most heroic guy out there. He definitely gets distracted quite easily by the heroines around him and I don’t always think he’s reasonable with how hard he tries to keep his army from fighting anyone. If the humans start something you should absolutely take them down in self defense. Rimuru’s definitely not as bad as Haruyuki with his questionable moments but he doesn’t hold a candle to the cooler light novel leads like Kirito, Orphen, or Lina. I wouldn’t say I ever became a big fan of the guy, he’s just decent at best.
In his slime form is definitely seems very powerful but I guess there’s less ways to use his magic. Once he gets a human form then that’s no longer a problem. As mentioned though, I do feel like this cheats on the premise a bit. The idea was that it would be a slime as the lead because the whole thing is so crazy that you’d have to see it to believe it. How could a Slime function as a main character indefinitely? The tough part of the premise is that a lot of people wouldn’t really find the design all that interesting and so the show would have to be really creative to keep him at the head. I feel like even the writer realized this was only going to work for so long and then introduced the human form.
I do think the human form is an improvement over the slime one so I’m definitely okay with it. The fight scenes are better with it naturally and while the Slime’s abilities are technically the same I do feel as though Rimuru is more skilled when using the human mode. Perhaps that is placebo but it appears to be the case right now. Rimiru is also one of the most powerful characters in this world due to all of the abilities he’s accumulated. He can copy and distribute wealth at will and even grants many different monsters a name which causes an instant level up. That was a pretty interesting idea and shows that names have a whole lot of power in this world.
The most effective tool at Rimiru’s disposal is the Predator ability. It allows him to eat/absorb any opponent and get their abilities. So far there has been nothing able to surpass it so we’ll see if that rings true long term. At the very least if Rimiru keeps absorbing a lot of characters during the series his power should continue to grow. We do know that there are opponents who can best him though like the demon lords. Right now their fighting abilities are on a different level so Rimiru wouldn’t even have time to use his absorption. That seems to be the only way to stop him so far.
The next arc introduces us to Shizu. She is a legendary fighter who looks like the hero of legend. She was transported to this world from Earth like Rimiru and fights as a solitary warrior. She always has to be careful because the fire spirit is within her ready to take control at any moment. She’s a very solid character to be sure. She may not have gotten to appear for very long but her role was quite solid. She did a good job of holding back the spirit as long as she could.
Her fighting techniques were definitely on point as well and the mask was cool. It would have been nice if Shizu could have appeared a little longer but there’s always the flashback option for that. I’m a little surprised her human friends took the way Shizu went out as calmly as they did but I suppose they understood what had happened. Rimiru took the loss especially hard despite not knowing her for very long. As the first major action arc in the saga this one definitely went over very well. The show was able to handle the serious tone here and Ifrit made for a tough opponent to deal with. This also introduces some elements like the first demon lord that will come into play soon.
Next up is probably the biggest arc of the series which introduces the Orcs. A mysterious mage has appeared and transformed the leader of the Orcs so that he becomes a huge monster. The rest of the Orcs have also been upgraded so they are effectively undead monsters who grow ever stronger by eating their foes. This unnatural army has been gaining ground and troops as they go through the land. It’s finally become a problem even for the alliance so Rimiru decides to step in after making an alliance with a nearby Orc village. This gives us a few new allies such as Benimaru, Shuna, and Shion. The Orcs are really outmatched but with Rimiru here to help they should be fine.
A wild card though is that the Lizard tribe is under attack as well and their troops may not be quite as thrilled about a partnership. Rimiru makes them an offer though and whether they accept or not could have a big impact on how things play out. Rimiru’s always trying for a peaceful alternative so it’s not like he would force the Lizards to join the team. If they refuse then Rimiru would leave them on their own but of course they stand no chance of beating the Orc army on their own. Whether they admit that or not.
Lets quickly talk about the characters from the Orcs, Ogres, Lizards, and even the Goblins since I haven’t mentioned them yet. Rigurd was the chief of the goblins and ends up being Rimiru’s most devoted follower. He’s a nice guy who means well. The guy may be a comic relief character most of the time but he’s well meaning and always tries to help out. He may not be a great fighter but he gets the job done. Gobta is a much younger Goblin but one who can actually fight fairly well for his age. He gets some solid swordplay moments during the series although I would still not trust him to be out there in a serious fight. I don’t think he has quite enough battle experience yet.
Then you have the Ogres who are easily some of the stronger fighters after Rimiru. Benimaru is the main one and along with his fellow warriors wants to avenge his village. He is able to form large explosions with his magic. The range on those things is absolutely crazy so the characters definitely need to keep their distance when fighting him. I like the guy, he has a lot of spunk and personality. He’s also a solid tactician and has contributed a whole lot. Then you have Shion who is also a very determined fighter who gets violent very quick. If anyone badmouths Rimiru then she steps in. Shion’s also one of the more heroic fighters as she is quick to volunteer the alliance’s help to stop villains when a threat is approaching. At times Rimiru isn’t even ready to declare such a thing but naturally at that point he has no real way out of this.
Shuna doesn’t get quite as much to do as the other to. After her transformation we have yet to see her really get to fight along with the others. Her abilities seem to be based on poisons and such but hopefully she has an offensive ability along with that as well. She’s a nice character though and also someone you can count on at the end of the day. Then there’s Soei and in terms of ability I have to say that I find him to be the most impressive fighter. His wires are super thin so it’s easy for him to lay a ton of traps. He’s also got great speed as well. The scene where he easily intimidates all of the Lizards was great. Due to his ninja training as well it’s just hard to see many opponents give this guy a real run for his money.
Hakuro is effectively the coach of the group. He’s a lot older than the others but thanks to Rimiru giving him a name the guy can still fight rather well. His speed is really on point and his technique should still be the best among all of the Ogres. While I do think he’s been surpassed by them, I can see how he would be very useful in combat. Abil is the leader of the Lizardmen and he’s definitely a solid guy to have around. He doesn’t let pride get in the way like Gabil. That said, he doesn’t get a whole lot to do in this season because of all the characters ganging up on him. Then you have Gabil and I appreciate his confidence but his unwillingness to work with the heroes leads to a whole slew of issues. To an extent it’s good to want to solve your problems on your own but it does get to a point where he is just getting in the way the whole time.
Geld is one of the big villains of the Orc arc. He ends up getting a ton of power thanks to the spellcaster but it’s not like he ever really wanted this ability. He just got desperate because of how tough the circumstances were for them. I’d say now that he has a proper name he should be set as a solid good guy. He could make for a decent ally although in terms of personality I wouldn’t say he adds much to the dynamic so I’m cool with him just being a supporting character. Gelmud is the spellcaster who put the Orcs into this position and the guy’s not very smart. You’d think that when summoning a monster of near limitless power like this that you wouldn’t antagonize and insult him right? There’s no way that is ever going to end well and naturally he found this out the hard way. It’s hard to feel bad for him because…really? Not a great moment for him.
Gazel is the King of one of the human kingdoms. He hasn’t done a whole lot yet but I could see him having a good role soon. At least right now he gets along with Rimiru fairly well although he is also a bit cautious which makes sense. It’ll be interesting to see how his character goes. Then we get onto the next arc which debuts Milim, one of the Demon Lords. There are quite a few demon lords by the way although most of them haven’t done much yet. Leon’s still causing trouble in the background like how he messed things up for Shizu but he hasn’t really gone to the forefront yet. He is responsible for this next arc though.
So after Milim shows up and joins Rimiru’s team, we then find out that a giant monster has been awoken. His name is Charybdis and it’s a monster of unimaginable power. With a single blow he can do this and that. While Milim could beat him easily enough, Rimiru is pressured into declaring that he’ll handle this without help. Lets just say that it’s not so easy especially due to the size. Even Predator would probably have a tough time here. It’s a fun enough mini arc mainly thanks to Milim being so much fun. She’s really a standout character.
Milim is easily the most powerful fighter we’ve seen so far. She’s able to end most threats in a single punch and has boundless confidence. She is absolutely someone you want to have on your side and the heroes should be lucky that she is so well natured. Milim is like a kid so as long as she has good food and the people are nice to her she’s happy. If anything Rimiru gives her a tougher time than he should because she is always ready to help the others out quite a bit. Without her the alliance wouldn’t be in quite the good spot that it is. I’m sure there will be a moment coming up where she has to choose a side though and that could get tough for the heroes. I like to think she would side with Rimiru but we’ll see. She just puts the rest of the characters to shame so if she’s an enemy then the whole alliance may as well throw in the towel now because they’d be doomed.
Then there’s a mini arc where Rimiru goes to teach Shizu’s students. It’s a fun little adventure and the kids have some fairly promising abilities. If anything you feel bad for them because Rimiru’s just way too powerful so there’s no way they can hope to defeat him in a fair fight. I could see them being fun supporting characters down the road though especially now that they have powered up spirits which should really increase their abilities in the long run. The series is really built around every character powering up so why should the kids be any different right? They fit right in.
Finally we end off with an episode all about Shizu in the past which was nice. She gets to go to a kingdom where everyone is uniting against a common threat. The issue is that there’s a lot of infighting and then it turns out a demon is in their midst as well. We get to have a pretty great fight with Shizu and a demon known as Kuro. Interestingly enough he got the big cliffhanger stinger scene at the end of the season so getting to see him in action here was a little unexpected. It’s like a nice hinting at things to come though. Already I can say he’s one of the best characters in the series. Milim would be my favorite but this guy is a solid number 2. Shizu would be 3rd and the legendary Hero might be 4th but we really don’t know much about her at all yet. Additionally I fully expect her to be evil when she showed up. This episode also shows that Shizu could have held her own series rather well because this last episode is a blast. It makes a case for possibly even being the best episode of the season.
As for negatives, well as mentioned I really only had 2 issues here. The Direwolves in the first few eps. Rimiru definitely could have found a way to defeat them without murdering a bunch of them. Animal violence is always a risk in any fantasy setting because creatures are all around. Fortunately it’s not particularly explicit plus they’re combat animals and the scenes were brief so all in all it wasn’t a total show crusher the way it could have been in other contexts.
Same for the fanservice, it’s around but it’s nothing too crazy. If anything the show tends to dial it down early on so after Rimiru’s initial moments it’s not a huge focus. It just tends to happen here and there. At most for most of the second half you could say that the designs may not be the best but a design in itself I wouldn’t consider to be fanservice the same away as intentional scenes. The show has both but as long as it keeps to this level and doesn’t get crazy I don’t see this holding the show back either. So the Slime franchise looks to be in good hands.
The animation throughout the show is very good. There’s a lot of consistent animation throughout and everything is very smooth. In particular the fire effects always look really nice. It’s definitely got a budget and looks like how a modern show should. The final episode also really stands out for looking excellent. Then there’s the soundtrack which is also very good. There are a handful of different fighting themes that all work out quite well with the action scenes. The themes are very memorable and I definitely listened to them quite a few times after the show ended.
One thing that was interesting though was in the opening we see a cool sword fight between Rimiru and a mysterious sword fighter but it never actually happens. The whole time you’re waiting and in the season 2 promo it appears so I feel like the animators maybe jumped the gun on that a bit. I guess it works as solid foreshadowing though.
Overall, This first season of the slime adventures definitely went over very well. It’s got a pretty solid atmosphere and assortment of fights and humors. I like that it had fun with the classic “Protagonist is overpowered” angle as the first episode is basically the system giving Rimiru a ton of extra powers so that he will be broken in every single way. The A.I. is also fun to follow although I don’t buy into her losing so easily against the Orc. You’d think that with her vast intelligence she would have used Rimiru’s abilities a little more wisely. The animation is solid and the show covered a whole lot of ground in these episodes. It does have some issues keeping it from being a great show but for now very good is a solid starting point. I look forward to seeing if season 2 can top this one. It certainly looks like it’s gonna be very action packed that’s for sure.
