In every manga series, the presence of villains alongside the protagonists is indispensable because they are the factors that make the story more attractive and engaging than ever.
Today let’s review the 6 strongest ranked demons.
6. Nezuko Kamado
If mentioning the power of Demons, Nezuko will still be counted in this list.
The most special thing about Nezuko is that she can walk in sunlight, this is her superiority compared to the 5 Demons below.
5. Hantengu

Hantengu is a member of the Twelve Demon Moons, holding the position of Upper Four.
Although he is a man with a strange appearance and is timid compared to other demons, he has an extremely formidable Blood Demon Art, and even has the extremely terrifying ability to hide himself, causing the workers to hide.
The main reason why Hantengu is on this list is that killing him is extremely difficult.
4. Akaza

As a High Demon himself, it is not surprising that Akaza appears on this list.
Akaza is also a power and battle fanatic.
3. Doma

Appearing with a flashy appearance, Doma with the title High Demon Demon is famous for being a very intelligent demon.
Doma has the ability to `absorb` humans, even without having to eat like other demons.
Besides, Douma possesses the ability to recover from wounds extremely quickly.
2. Kokushibo

Kokushibo is known as the strongest Demon leading the 12 Mysterious Demons under Muzan.
In the past, he was a Demon Hunter who displayed the Demon Slayer Seal but left the righteous path a long time ago due to his desire for power and wanting to surpass his younger brother, the legendary swordsman Yoriichi.
His dangerous point is that he is extremely good at swordsmanship, and has lived long enough to grasp the strengths and weaknesses of the Demon Hunter’s moves and breath.
1. Muzan Kibutsuji

And the final boss is also the strongest Demon ever known, Muzan.
Muzan is the demon with the most terrible ability to regenerate, even when his body and head are broken.
Since becoming a demon, Muzan has lived for centuries without aging, as well as immunity to diseases.
And in this final battle, if it weren’t for Tamayo’s `aging` medicine and Yoriichi’s old slashes, the Demon Hunters would have absolutely no ability to defeat Muzan.
