Who are the Twelve Kizuki in Demon Slayer ? Explained

Demon Slayer has a lot of solid demons but of all these, the Twelve Kizuki or the Twelve Moons are the strongest of them all. They report directly to Muzan and can use Blood Demon arts to their utmost perfection.

They are the central antagonists of the series and the toughest enemies, Tanjiro faced in his journey. So strong are these demons that even Hashira appears marginal in front of them.

So you might be curious about how these powerful demons came to be and what’s their strength levels. Well here at MyAnimeGuru have made an elaborate article on everything related to the Twelve Kizeki.

So without wasting any more time let’s get on with it.

Twelve Kizuki Explained

Twelve Kizuki - upper moons

Twelve Kizuki are the strongest demons in the world of Demon Slayer, second only to Muzan, the demon king himself, and are only challenged in strength by The Hashira. So let’s jump into the structure of the Twelve Moons.



As already mentioned, the Twelve Kizuki are the 12 strongest demons who were given blood directly by Kibutsuji Muzan which made them capable of handling all kinds of unique Blood Demon Arts as well as many favours and distinctions given to them.

The twelve kizuki are the main task force of Muzan and generally perform tasks that are important towards Muzan’s goals. These tasks could be anything between the killing of Hashira, finding the Blue Spider Lily or /and the killing he deems too dangerous to be kept alive.

The strength of the Twelve Kizuki is not the same and thus is divided into 2 subgroups. One is the Upper Moon and one is the Lower Moon.

The Lower moons while comparatively strong and having powers beyond any typical demon are still no match for Hashira-level Demon Slayers who are easily able to defeat them.

Lower moons just have one of the eyeballs marked with the Kanji of their rank. Even Lower moons of the twelve kizuki can use Blood Demon Arts.

Generally, the way to become a member means that a demon has to somehow get Muzan’s attention by either killing a lot of people or by being incredibly strong.

Sometimes even humans are directly promoted to twelve moons if they’re strong enough. A good example of this would be Kokushibo and Akaza, who were both humans and directly made into Upper Moon demons.

The more Muzan gives to a demon, the stronger they are. That’s why lower moons have less blood than Upper Moons.

As a testament to the Upper moon’s sheer strength, it’s been said that the Hashira have killed many lower moons over the years while the Upper moons have killed and eaten many Hashira over the years.

It’s been said that no Upper Moon was killed in over 113 years while numerous Hashira lost their lives in that period. The Upper moons also detest the Lower moons.

The members of the twelve kizuki are also given many privileges and are exempt from the typical expectations of the demonkind. These privileges are like when Akaza was exempt from consuming women as he hated it.

We can also see it with Lower Five Rui who was allowed to have a family despite Muzan not allowing demons to band together.


The start of twelve kizuki started with the conversion of Michikatsu Tsugikuni into a demon more than 500 years ago.

Michikatsu was the older twin of Yoriichi and after being scarred by him, Muzan decided that he needed subordinates to fight instead of him. Michikatsu blinded by his jealousy of his brother pledged loyalty to the demon king, Muzan.

This resulted in him being given the powers of his blood, thus in the process becoming the first Upper Moon. He is also the only human to directly become an upper moon other than Akaza.

Books Worth Reading:

Since then Muzan has given his blood to countless individuals who went on to become parts of the Lower and Upper Moons.

Generally, the members hold the position eternally but sometimes when a demon loses their favour with Muzan or gets killed in battle, they are eventually replaced.

One unique example of this is the former Lower Six Kyogai who reached his limit to consume humans and thus would no longer be able to grow stronger and was thus replaced by Kamanue.
