/ By

Demon Slayer: Kimetsu no Yaiba is the anime that is crushing it in this 2025 and that also did in 2023 – 2024, now even more with the arrival of its first movie of three that will be available in theaters. Here we explain everything about the anime and more interesting things that you didn’t know or imagined.

What is Demon Slayer: Kimetsu no Yaiba about

The anime is about a world in which demons exist that come out at night to hunt humans for food, based on this atrocious event, people who lost family members, in the desire for revenge or to help prevent such an event from happening again, help the slayer organization under the command of the “patron” who is the general in command of the entire organization.

Within this organization, only a few are chosen by the patron to be a ‘pillar‘, someone capable of standing up to the upper moons.

What is a pillar?

A pillar is a person super developed in skills and powers beyond logic, capable of standing up to the upper moons who are under the command of Muzan. A normal human is very far from being at their level, that is why many have respect for the pillars.

What is an upper moon?

An upper moon is a demon, an upper moon, they are like Muzan’s special generals with strength out of the ordinary, an unprecedented danger to all of humanity, if they could go out into the world when the sunlight is out, the whole world would be destroyed in the blink of an eye.

The way they became upper moons was because of drinking the blood of master Muzan as they call him, this usually happens when he considers them strong in their human form, so we can conclude that they were fighters who faced him and ended up losing.

Lower Moons

They are those who, like the upper moons, have great power, we can see it as a high rank but low, far below what Muzan expected, he expected all of them to be upper moons and for that reason in the anime he ends up eliminating them to only keep the upper moons.

Weakness of all demons including Muzan

Demons, even Muzan Kibutsuji, are eliminated if the sun hits them, the sun disintegrates them, burns them and ends up eliminating them. This is a great weakness they have because even though they are very powerful, they must live in darkness.

With the exception of Nezuko when she becomes a demon, she is able to withstand the sun, thus managing to become Muzan’s main objective to absorb her and take her ability to survive the sun.

Enemy number 1

“Muzan” This is the reason for the existence of all demons, lower moons and upper moons. By forcing them to become demons by drinking his blood.

Characters

Look at the characters in order, the pillars, the main characters, the secondary characters, and others. This is a complete list of characters that will be updated constantly.

Movie – Kimetsu no Yaiba: Mugen Ressha-hen (The Infinite Train)

Season 2, Part 1 – Mugen Train Arc (Series Version)Episodes: 1 to 7These events cover chapters 54 to 66 of the manga.

Some people might get a little confused between the season and the movie, but don’t worry, it’s just that the movie was adapted into a series format, so you will find the same story as the movie, but with extra scenes and narrative reordering. You can choose which format to watch without a problem.

This part of the story shows us the time Tanjiro and company spend with the fire pillar: Kyojuro Rengoku, on an unexpected adventure, where we can finally see the true potential of the new slayers.
