Life is a grand adventure. You never know what’s going to happen. One second you’re just minding your own business, living a contempt if a little lonely life, appreciated by your colleagues and kouhais, the next, you’re a slime. You know how it goes. Now you would think that reincarnating as a featureless slime might be a drawback but that’s because you lack imagination. Life is what you make it, and for the great monster Rimuru, life as a slime is to get exciting, filled with new friends, wild adventures, bittersweet romance and a lot of urban planning!
No matter how many times the universe proves me wrong, I still obstinately try to fool myself into thinking I know what to expect. I don’t. I’m almost always wrong. Why haven’t I learned my lesson yet? Does it have something to do with having a blog filled with drinking games? I don’t see the connection!
I’ve been watching anime for a while. Long enough to have started making some associations based on steaming service thumbnails alone. It’s a gift. A particularly useless one. My accuracy rating is pretty abysmal but unfortunately, it’s not zero. So, every time I get one right, I fool myself into continuing the practice. The thumbnail for That Time I Got Reincarnated as a Slime was:

And from this, I instantly understood that this was a generic fantasy-based isekai. You know, teenage boy transposed into a new world, suddenly incredibly powerful for some reason and surrounded by a harem of luscious admiring ladies. My success rate: 50%?
Sure, That Time I Got Reincarnated as A Slime looks pretty standard. Nice but nothing special. Both the visuals and the general narrative outline are extremely familiar to anyone that’s seen this genre of anime. If you just gaze at it from a distance or base yourself entirely on a thumbnail you can think that you’ve seen this show before. Dozens of times before.
And just like I was, you would be kind of right. But slime isn’t a big picture show. It plays with the details, gently subverts tiny expectations, it piles on subtle innovations and small-scale tweaks until your left with a completely new type of monster.

And this new monster is an unexpectedly mature and levelheaded one. I figure this will either be refreshing or boring to most viewers. I’m not sure what it says about me, but I really liked it. In fact, I started to get excited at the end of the day, just because I would get to see more episodes.
One of the very first things that hit me is that the main character is not a teenager. In fact, he’s a mature man close to 40 that has led a rich life. Even though he’s rather inexperienced on the romance side, he’s a generally happy and well-adjusted member of society and… he acts as such. Even when transformed in the adorably voiced Rimuru, his way of thinking and reactions, remain true to his personality. Meaning, measured, thoughtful and not too loud. Boy was that a welcomed change for me.
Oh, and while I’m talking about Rimuru, it does bear mentioning that although he remains an adult man in spirit, he is a genderless anthropomorphous blob in practice and that also has a surprising amount of influence on the character, considerably changing the valiant hero archetype and the impact his action have on the audience. It’s a drastic break from the heroes I’m used to seeing.

You may have picked up on the fact that I mentioned city planning in my summary, and that’s another wonderful break. If I were to liken That Time I Got Reincarnated As A Slime to a video game, it isn’t as much an RPG as a Sim. The true heart of the series isn’t in the spectacular battles and powerful foes but in the quiet moments of diplomacy and city construction. Rimuru isn’t a conqueror, even if he has the skills for it, he’s a builder. And as someone who spends indecent amounts of time creating home bases in Fallout, this aspect spoke to me. I admit it’s not for everyone.
This is a series that favours conversation to action, not that there isn’t any action, but if high adventure is what you’re seeking, I suppose you may feel a little let down.
I should say, in many ways Rimuru is a Mary Sue. I kept thinking to myself, “well that was easy” or “sheesh slimes are overpowered”! This is generally not considered very good character construction. Yet it didn’t bother me much, or even at all. I’m still not entirely sure why but I think I have a basic explanation.

The conflict in That Time I Got Reincarnated As A Slime doesn’t come from the confrontations. It a story that’s driven by collaboration instead. The point is not to follow a hero overcoming dire foes and immense obstacles, but to watch a community bloom and an outsider find their place within it. See, it’s not sounding so much as your standard harem isekai now, is it? Maybe it is, anime is fantastic at ignoring genre conventions!
Let me just touch on the romance for a bit. This is exactly my type of romance. Bitter-sweet, largely unrealized and present for roughly ½ episode out of 26! But you know, despite hardly being present, Shizu was so well established that I started to deeply care for her. And her own status as an outsider, an adult with clearly adult preoccupations and dreams, and a kind and gentle made it quite clear why Rimuru would also care for her.
This thought of living and entire life without finding love only to be thrown in another universe to find your one fated one just to immediately lose her again was both devastating and very pretty. An illustration of it’s better to have loved and lost than never to have loved at all. Ans it warmed my cold little heart without getting on my nerves!
But it remains a fairly small part of the series, more symbolic than present. If you are itching for a romantic adventure or some harem mischief, That Time I Got Reincarnated As A Slime is likely to leave you wanting.

TLDR: That Time I Got Reincarnated As A Slime is a well written, light-hearted and understated series of adventures that will bring in mind an old fashion D&D run with a civilization twist.
Random things I noticed: Some of you may know I have an odd interest in “names” and the importance of naming monsters in this show really thrilled me. It is a nice message that a recognition of personal identity brings with it power! I also found it a little narcissistic that by and large, evolution for monsters made them more humanoid looking.
Favourite character: Shion (who wouldn’t love Shion) also Veldora

What this anime taught me: A “silver fox” (i.e. attractive older man) in Japanese is called a “romance gray”. Amazing!
Everybody’s got to believe in something. I believe I’ll have another beer.

You explained perfectly what made this iseki charming and interesting. It was just different enough, and different in a kinder, gentler sort of way. I really liked this one.
Gentle is a great way of putting it. I think gentle is a very underrated quality
Didn’t care for it as a manga, didn’t care as it was airing.
After this, I’ll probably check it out.
Really!?! The pressure
Ooh, I remember that show quite fondly. I also remember losing some of my enthusiasm for it as the season progressed. I think it’s a show that’s best binged, or maybe watched an arc at a time (weaker episodes have less weight that way).
I’d agree that monsters looking more human after a power-up isn’t exactly the best part of the show. Especially for the ogres, I preferred the orignal designs, but also for the lizard men (except for Gabiru, who merely got wings). In that respect, I did really enjoy Gobuta, the only character I remember whose appearance didn’t change at all after being named. A smart, laid-back, confident little goblin. I really liked him.
Also, despite only limited actual screen time, Shizuru provides the direction for the entire show – the major plot mover. It’s sort of interesting. I wonder if it’s a co-incidence that the little girl whose name I forgot looks so much like her? I mean it’s not her, obviously. (I’m thinking she’s somehow the hero who defeated Veldora and then went back in time to possess herself – that would make for a convoluted bond-structure: I mean if she didn’t defeat Veldora, Rimuru wouldn’t meet him and in turn couldn’t save her, and also that would explain why she one day just left Shizuru [or Shizuru wouldn’t have met her]… Idle speculation.)
Shion was awesome, but then I liked all the ogres (and wish they would have retained their original designs.) And Veldora is pretty great, too. Tsundere dragon.
You know I bet it really is best binged. There’s a flow to the narrative that’s not quite consistent and one episode a week must not have done it favours
Slime-san is one of my favorite isekai 💙 as a fan of the Civilization games I loved that they showed all the growth from a village to a nation. Rimuru is probably my favorite isekai protag (although that’s maybe not saying much) because of their gender ambiguity and chill attitude. It’s really cool to see a fantasy series that’s more about bringing people together rather than fighting. I can’t wait for season 2!
Same! And a pretty cool role model for younger viewers too. It’s not something I pay much attention to usually but it was really nice to see
I got a lot of enjoyment out of this series. Good fun, and not what I expected either.
I really hope there’s another season
Me too. It was such a fun take on the genre.
