Top 10 Theories of Demon Slayer You Should Know!

One of the most watched and talked about anime over the past few years has been Demon Slayer. The first two seasons offer an incredible amount of plot and action.
Numerous Easter eggs have been discovered by anime watchers, who have also developed a variety of their own hypotheses. The anime is considerably more enjoyable to watch because the writers spent a lot of time and effort on the smallest of things. The top 10 demon slayer theories are shown below.
1. Nezuko’s Change
The reasons Nezuko became into a demon and did not join the rest of her family have given rise to a number of ideas. Muzan did not intend to kill the entire family; that was an accident.
Many elements from Shinto religion and Japanese mythology are used into Demon Slayer. The Kamado family performs the “dance of Fire God” every year as a sacrifice to God since ancestors are revered in the Shinto religion. The ancestor’s spirits may have saved Tanjiro and Nezuko, as some viewers have pointed out.
2. The Hanafuda Earrings of Tanjiro
It is quite a mystery how the Hanafuda earrings were passed down through the centuries after the Hinokami Kagura to the man born into the Kamado family. When Muzan Kibutsuji noticed Tanjiro wearing the Hanafuda earrings, he was agitated.
Muzan instructs his two men to follow Tanjiro after catching a glimpse of a man with red hair and the identical earrings from his past. He was reminded of Yoriichi, the sole demon slayer who nearly murdered Muzan, by the earrings.

3. Muzan, in Search of the Blue Spider Lily
The first demon supposedly formed was the Demon King Muzan. He is looking for the blue spider lily because it will give him solar immunity, which will enable him to become everlasting. The blue spider lily is thought to be able to rejuvenate and produce devils.
Muzan’s body can be harmed by sunlight because he is weak and susceptible to it. When Muzan was on the verge of death, the doctor who had assisted him was killed. Muzan made it his mission to locate the flower despite all obstacles because the doctor was the only person who knew where it was.
4. Sun Breathing
One of the first Breathing styles developed is also known as Hinokami Kagura. The Sun Breathing technique was developed by Yorichi Tsugikuni, and all other breathing techniques are descended from it by changing it to suit the requirements of various people.
The practitioners of this approach imitate the sun and its movements and methods. Because each technique and form is unique, they are all incredibly effective against demons.

Along with the Hanafuda earrings, this breathing is passed on from father to son in every generation. There are 12 practices associated with each style of Sun Breathing. Later, Yoriichi met with Muzan Kibusuji and developed a brand-new nameless technique.
This method has been employed by the Kamado family, and Tanjiro is the most recent user who picked it up from his father Tanjiro Kamado. During the Natagumo Arc, Tanjiro first utilized the Sun Breathing against Rui. Because it boosted his total power and quickness, he understood that his body was better adapted to this breathing technique.
5. The Sword of Tanjiro
Nichirin, Tanjiro’s sword, is black for thematic reasons and has a deeper significance. Sunlight, which is a weakness of demons, has been injected into nichirins for Demon Slayer. The swordsmith claims that the nichirin’s colour and painted portion rely on the user’s personality and breathing style, respectively.
The black sword, which may be created by blending all the colors, could symbolize the sun breathing because it is the source of all other breathings.
Black might also allude to Tanjiro’s family business, which involves selling charcoal, which burns bright red hot. It might possibly be a homage to the God of Fire, who is revered by the Kamado family.
6. Scar of Tanjiro
Tanjiro protected his younger brother from getting burned, which resulted in the scar on his forehead. The scar takes on the form of a mark as Tanjiro gets stronger.
When Tanjiro is in danger and when using the Sun Breathing technique, the mark becomes active. The scar on his forehead is the Demon Slayer Mark, a birthmark or mark that resembles a tattoo that gives its owner superhuman strength and is closely related to the Sun Breathing method.
7. Twelve Demons Motivated by Illness
Fans have emphasized that the Twelve Kizukis were motivated by illnesses. When supported by the idea that the first demon emerged as a result of an infectious illness whose treatment was still lacking, this explanation makes sense.
Daki may represent syphilis, Gyutaro may represent congenital syphilis, Kaigaku may represent human scabies, Gyokko may represent amoebic dysentery, Hantengu may represent leprosy, Nakime may represent infectious conjunctivitis, Doma may represent stage 2 TB, and Kokushibyo may represent the bubonic plague or the black death.

8. Silence of Nezuko
Fans have observed Nezuko‘s bamboo muzzle and the fact that she is silent. Some people think that Nezuko’s cognitive talents were lost when she turned into a demon. She must eat human flesh to heal it, but she refuses because she doesn’t want to hurt any people.
Another idea is that she made a vow of silence to train her intellect and restrain her demonic urges in order to maintain her humanity. The Japanese religion of Shinto, which emphasises stillness as a means of achieving inner calm and spiritual development, includes characteristics that can be found in Demon Slayer.
9. The Bamboo Muzzle, by Nezuko
All of the viewers are aware of the significance of Nezuko‘s bamboo muzzle and that it is not only a matter of character design. Nezuko appears to be in control of her demonic self, and a spell has even been cast on her, but since she is a demon, no one can predict when she will lose control.
She is able to restrain her demon rage while protecting everyone nearby thanks to the bamboo muzzle. Nezuko can blend in with the others and appear human thanks to Bamboo Muzzle. Not to mention how adorable Nezuko-chan looks as a result!
10. The Pig Head of Inosuke
Inosuke is a figure that is immediately recognized thanks to the pig head he always sports. He tells a depressing tale about growing up with boars and being socially awkward.
In order to escape her abusive husband, Inosuke‘s mother joins a cult that was controlled by the demon Doma without her knowledge, where she is murdered by him. As a result, Boars raises Inosuke and gives him the hollowed-out head of his mother to wear as a memento of her.
