Tensura Nikki: Tensei shitara Slime Datta Ken

Slime Diaries is an excellent addition to the original series as a slice of life bonus, doing its best to help build the more casual essence of the world at the work that goes into maintain the city and its people (as-well as the culture). For anyone that has watched through both seasons 1 and 2, I believe this is a must watch. Its not Canon... However I feel that if you've already watched through the entire series then there isn't really any reason why you wouldn't also watch this. It's just more content.


For those that haven't watched the original show, its harder to recommend ... just this season. If I was trying to get someone into Tensei shitara Slime Datta Ken, then I would just point them to the first season, going from there as a starting point. If they enjoy the show enough to keep watching (including specials and the movie) then why not also include Slime Diaries.


While its not action packed, it still has some great animation. Doesn't feel like it overstays its welcome and integrates lots of Japanese culture that isn't as prevalent in the mainline series.


Would I recommend? Yes, but only if your already interested in watching Tensei shitara Slime Datta Ken, if not then don't bother. You probably wouldn't get anything out of it if the first or second season didn't interest you.

This is a slice of life variant of that time I reincarnated as a slime. It is set during the first season of that time I reincarnated as a slime and you can't really watch it without watching that first. You don't have to watch the second season though.

The story is, as you'd expect from a slice of life, not very consistent or interesting. Every episode is about something new, generally a holiday from Earth that Rimuru tries to implement into the world he finds himself in in some way, shape or form. Some of the episodes actually contain additions to the main anime; ... for example there's an episode about farming which explains how the city gets part of its food. Overall the tone is completely different from the main anime but I think it's an okay slice of life.

The characters are the same as in the main anime. The difference is that in this version different personality traits receive more attention. For example Benimaru is more controlled by Shuna, the sister dryads are jealous of the main dryad and Rimuru is always made to dress like a girl in different outfits. Overall the character design for everyone is cuter which is also very noticeable looking at the background characters.

The animation and music are both okay. The voice acting is the same as in the main anime and is fine.

All in all I'm not sure if people will like this. The entire atmosphere is way different than in that time I reincarnated as a slime since it's a slice of life anime. If you like slice of life anime and like that time I reincarnated as a slime then you'll probably like this one too. If you don't like slice of life anime, you probably won't like this either. It's not watching just for the additions to the main story at least since there's too few and they're relatively insignificant.

The genre of the spin off is : Comedy, Fantasy
If it was slice of life, I would have given it a 6 at best.
Even Slice of life animes like "By the Grace of the Gods" and "The Weakest Tamer Began a Journey to Pick Up Trash" or Food animes like "Delicious in Dungeon" have better character development and plot.
Even Naruto fillers had better character development and plot than this.
This spin-off is as bad as the fillers of One piece (including the 23 minute clay animation episodes).

The characters follow their simplistic character traits and have no growth.
The stories are neither humorous nor worth pondering.
You can't just ... take fillers of 23 min each and turn them into a spin off.

Spin off is supposed to have a story of its own.
The Konosuba spinoff had some story and gave the spin off character some depth.
If you accidentally landed on this anime, please skip it and save 4 hrs of your life you will never get back.

The 1-2 minute mini clips at the end of Shangri La Frontier have more story and character depth than this entire spin off.
