It is just another ordinary day for Satoru Mikami. The sun is shining brightly on the streets of Tokyo, and he is in the midst of a discussion with his colleagues when suddenly he gets stabbed by a passing robber. The average 37-year-old corporate worker is now at death's door, and he has only one regret—dying a virgin. Fading out, he is startled by a mysterious AI-like voice reciting commands.

Satoru abruptly wakes up in the middle of a strange cave, but something odd has happened: he is now a goop of slime! Thanks to his new body, he has acquired the skill to absorb anything and obtain its appearance and abilities. While testing out his newfound powers and exploring the cave, he stumbles upon a massive dragon named Veldora, who has been sealed away for the past three hundred years. After quickly befriending the beast, Satoru decides to help him escape; in exchange, Satoru is bestowed a new name: "Rimuru Tempest."

Wishing to avoid a life like his boring and mundane past, Rimuru is about to set out on a grand quest that will change his own destiny and the fate of his new world.

Preliminary (91/? eps)
Just recently read this Manga until chapter 91. --SPOILERS--

In my opinion you can look at this Manga in 2 parts. The first half, until around 45, which is rather "boring" and the second half, where it picks up quite fast.

First, i wanna talk about the biggest problem i have with this manga, there are never any problems, in the whole story there is never anything at stake.

Orc Lord? Easily defeated, Rimuru just lets Great Sage take over.
Charybdis? "No Milim we will fight it ourselves", after 10 hours of fighting "oh yeah why don't you just kill it".
Commander of the Church will kill the MC? Luckily ...

Mixed Feelings
Preliminary (17/? eps)

It is a painfully average story.

That's it really. There's no factors in Slimesekai that you can't find done better somewhere else.

The only interesting facet of Slimesekai is the idea of reincarnating as a slime, and it's ruined within two chapters when the slime is A: not weak at the fuck all, B: not challenged by literally anything, and C: has no reason to even be a slime.

Ever played Terraria? Dragon Quest? Final Fantasy? Do you remember slimes being able to eat literally anything, absorb skills and attributes of those things, and just do generally unrealistic actions like shooting swords of water?

Yeah, that's not called ...

Artstyle and character design are generic, forgettable at worst.

The only notable thing I like is a specific Orc's tanky armor much later in the story. It looked kinda cool~

I don't care for them because they're either:
- Rimuru fanatics
- friends/allies
- future friends/fanatics, before they get their asses handed to them
