Hello!! In this post, we'll learn some interesting facts for beginners about Kimetsu no Yaiba (Demon Slayer), one of the anime currently. So get ready and let's get to it.
Fire is important

's family Nezuko and Tanjiro worked with fire, and even their surname, Kamado, refers to a traditional charcoal stove. Throughout their journey, we observe how much they respect fire, and in a flashback, we see the protagonists' father performing a ring of fire dance, a tradition performed on New Year's Eve.
Nezuko is a different kind of Oni

Early in the story, we are frequently shown that Nezuko still retains parts of her humanity and chooses not to hurt those she loves. Later, she is tested by Sanemi Shinazugawa and refuses to bite him, even showing displeasure at the prospect of doing so.
We then discovered that, instead of regenerating using human blood, she is able to recover while sleeping, which makes her different from all the other Oni presented throughout the work.
The mark of the Oni hunters

The mark of a Demon Slayer appears when they are in near-death conditions, usually when attacked by a Demon. We see this in the anime when Tanjiro wakes up after being attacked by a Demon named Gyutaro. The mark resembles tattoos or scars and grants the possessor extra abilities in battle, such as increased speed, agility, and strength; however, it comes at a price, as its bearers usually die at the age of 25.
The perfect Seiyu from the anime Kimetsu no Yaiba

Akari Kito is the actress who voices Nezuko in the anime; interestingly, she is the same height as the character, and one of the kanji used to spell her name is the same one used to spell the word "demon."
The Hashiras

The Hashira are considered the greatest demon slayers, the group being formed by nine members, and to become one, a candidate must now have killed fifty demons, or one of the strongest demons belonging to the Twelve Kizuki, that is, those directly commanded by the king of the demons.
Each of the Hashira has authority over a specific region, protecting the humans who live in these regions and monitoring any activity of the Oni in their lands.
The Ancestors of the Demon Hunters:
The siblings who are the protagonists of the story likely come from a powerful lineage of sword wielders, as in the manga, we see that Ninjiro has dreams about his ancestor, Sumiyoshi, and the two even share quite similar features. Some even speculate that their family is linked to the first user of the Sun Breathing technique, which would explain why Nezuko is such a unique Oni.
The bond between brothers:
This fact may seem obvious, but Nezuko and Tanjiro share an immeasurable sisterly bond. In the first episode, Nezuko protects Tanjiro, which is totally unexpected, since demons are known for feeding on their own family.
Tanjiro, in turn, demonstrates on numerous occasions his ultimate devotion and love for his younger sister, both in actions and in small things like carrying her everywhere while she sleeps in her box.
Finally, we can say that their connection is what gives them strength, and it's even possible that they combine their powers to discover new ways to use them and become stronger.
Furthermore, these are some interesting facts about the anime Kimetsu no Yaiba for beginners that I found important.
