Synopsis
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. [Written by MAL Rewrite]

Light Novels Series End

I am so emotional right now. My all-time favourite LN series has ended. All my love for fantasy and world-building in fiction is all due to this series. My heart is now void as there is no more content to feed from this. I shall cherish this moment and read the final volume with tears in my eyes and heaviness in my heart.

The manga adapts the light novel and also It doesn't matter. People jump to new things or things that continue to grow. Excluding some rare examples, this type of series growth start to die immediately after they end. And as a result Kodansha will start reducing the printing and will focus it's resources to ongoing series.

This series is in a peculiar spot, the publisher of the Light Novel and the Manga are not the same, and the Manga is a lot more popular than the Novel. Kodansha will not reduce their printing much; Slime is a top-tier hit for them, it's one of their most successful series in recent years, and had the largest initial print run.

I really wouldn't expect the franchise to die anytime soon.

I highly doubt the studio will fully adapt the series because it will finally stop being relevant since the source is ending.

The Anime is produced by the publisher of the Manga, not the Light Novel; that's why the opening says the source is the Manga, and also most probably why the pacing is slow, in general. Chances are that it'll continue having Seasons/OVAs/Movies as long as Kodansha publish it.

@mccreepyy Well the more you know. Still if you are good with this type of thing and have time, consider doing it in the future.

@K1nji_ I highly doubt the studio will fully adapt the series because it will finally stop being relevant since the source is ending. Trends change and they will most likely start a new ongoing series that will sell well. One of the purposes of the anime is to keep advertising the source material but the audience will stop growing (or at least it will never grow again that much) since the light novel ends. But even if they will fully adapt the series, the most important thing is that this series finally ends.

@Yubisoft the ln is ending, not the anime
