A JOURNEY INTO HELL

Now that Rimuru has risen to the level of Demon Lord, the pinnacle of monsterkind, the powers of the world inevitably take notice. Foremost among them are the other Demon Lords, who call a meeting known as a Walpurgis, a space for these fearsome figures to hash out their differences.

Definitely starting to get super exciting here! We have our first glimpses of the different Demon Lords as Rimuru attends Walpurgis, and whilst that's happening we have the attack on Clayman's forces, as Rimuru's people aim to find out what happened with Carrion, and stop the remainder of Clayman's plots before he gets what it is he was after.

You also get a pouting Veldora who really wants to destroy things but is instead having to take care of others instead. Poor kiddo :P

Chapter notes below for personal reference: (potentially spoiler heavy)

A Meeting of Monsters

With Rimuru finding himself elevated to the rank of a demon lord a meeting is being called by the rest if the demon lords at the bequest of the sneaky Clayman who has already shown his hand in several plots that have put him head to head with Rimuru and the nation of Tempest. Having decided to introduce himself Rimuru, Ranga, and Shion make their way to the gathering called a Walpurgis to finally meet some of these demon lords they have heard of and perhaps a few they have not.

In the meantime with Clayman and the church of Falmuth's involvement with Rimuru's evolution and the near death of many in Tempest certain groups have left Tempest to strike at certain targets to retaliate against the wrong doers but even with recent power boosts who will survive is yet up to debate.

Maybe Spoilers?

Claymam plots. Laplace causes doubt. Humans and Monsters gather to talk business. A betrayer has been revealed. Who is it? A delegation to Falmuth has been decided. Looks like Claymam has declared war. Enter Guy Crimson. Begin Walpurgis, one is not what they seem. A battle with Clayman’s amry has begun. Who will be the victor and what will be the results of Walpurgis?

O Diablos é um dos personagens mais interessantes de ler.

A volume of politics and one-sided army bashing. First off, the build-up and then the actual Walpurgis was pretty excellent. These here are the movers of this world. A showdown for Rimuru and Clayman is imminent. And speaking of Clayman, he's completely unaware that his army is getting hit hard by allied forces of Tempest and Karion's beastmen. And new reveal of just how powerful Milim's followers (or rather, worshippers) are. An interesting thing to note that the anime actually stretched out this build-up quite a bit - the planning for Walpurgis, the strategising, the logistics, etc. The manga pretty much just hints at it. Both are rather well, in their own way. And speaking of hints, I wonder if Rimuru got the hint of just who might be pulling the strings of string pullers.

The political intrigue continues as Rimuru concludes his meeting with the representatives of the neighboring friendly kingdoms while also making preparations for retaliation from Falmuth and a possible assault from the Western Holy Church.

But all that gets put on the backburner while Rimuru gets invited to a meeting of the Demon Lords called the Walpurgis, meaning he can confront Clayman face-to-face and figure out why Milim is helping him. Not only that, he finally gets to meet his nemesis, Leon Cromwell... only took him 17 volumes. Also introducing a lot of new important (?) characters.

The chess pieces are moving and I'm all for this~!

We get to finally meet the other demon lords and Rimuru finally gets to meet Leon which has been built up ever since Shizue was introduced. Also finally we get to see the three Beastketeers in serious fights. A lot of really cool stuff and it is nice to finally see Rimuru on the offensive instead of just reacting to things around him he is now becoming more active.

Things are starting to really move now. Between wars, meetings with nations and now a demon lord summit lol things are getting heated. It is really nice to finally meet all the demon lords and get a face on their names.

Dans ce tome, Limule se prépare à plusieurs combats : celui contre l'Eglise d'Occident et le royaume de Falmus, et contre Kleiman qui fait partie de ceux qui tirent les ficelles depuis le début.
Pour cela, Limule s'organise afin de ne pas se laisser déborder. Avec l'aide de ses alliés et de ses sujets dévoués, il prépare le banquet de la nuit de Walpurgis, lieu de rencontre entre rois-démons, en anticipant l'action de ses adversaires.
Tous ces préliminaires présagent un tome 18 riche en actions et en rebondissements. Affaire à suivre!
