All viewers know the origin of the bamboo snout in Nezuko’s mouth and that it is not simply a character design. Although Nezuko seems to be in control of her demon self and even has a spell, she is a demon and no one knows when she might lose control of her.

The bamboo muzzle helps her control her demonic rage while keeping everyone around her safe. Bamboo Muzzle also makes Nezuko appear human and blend in with others. Not to mention that it also makes Nezuko-chan extremely cute!

Inosuke is a character that can be easily recognized by the pig head that he wears all the time. He has a sad story about growing up with boars and lacking social skills.

Inosuke’s mother, while on the run from her abusive husband, takes refuge in a cult that, unbeknownst to her, was led by the demon Doma and is killed by him. Consequently, Boars raises baby Inosuke and he wears the hollowed-out head of her mother boar to honor her memory.

8. Twelve disease-inspired demons

Twelve disease-inspired demons

The fans have pointed out that the Twelve Kizukis were inspired by diseases. This theory makes sense when supported by the fact that the first demon arose due to an infectious disease, the treatment of which was incomplete.

Daki modeled after syphilis, Gyutaro could be a victim of congenital syphilis, Kaigaku could be modeled after human scabies, Gyokko after amoebic dysentery, Hantengu after leprosy, Nakime after infectious conjunctivitis, Doma after stage 2 tuberculosis and Kokushibyo after the plague or black death.

7. Nezuko’s Silence

Nezuko's silence

Along with the bamboo snout, fans have noted that Nezuko does not speak. Some believe that Nezuko lost her cognitive abilities when he became a demon. To restore it, she has to consume human flesh, which she refuses because she doesn’t want to harm any human.

Another theory is that she has taken a vow of silence to condition her mind and control herself against demonic instincts in order to retain her humanity. Demon Slayer has elements of the Japanese religion of Shintoism, which speaks of silence as a tool for spiritual growth and inner peace.

6. Tanjiro’s Sword

Tanjirou's Sword

Tanjiro’s sword, or Nichirin, is black for thematic reasons and has a deeper meaning. The nichirinas for Demon Slayer have been infused with sunlight, which is the weakness of demons. According to the blacksmith, the color of the nichirin depends on the user’s breathing style, and the painted part depends on the user’s personality.

Viewers point out that the black sword could represent the sun’s breath since all other breaths stem from it, and the color black is achieved by mixing all the colors. The black could also represent Tanjiro’s family occupation of selling charcoal that turns red hot when burned. It may also be a nod to the God of Fire that the Kamado family prays to.

5. Tanjiro’s scar

Tanjiro's Scar

The scar on Tanjiro’s forehead was a minor burn when he saved his little brother from getting burned. When Tanjiro gets stronger, the scar changes into the shape of a mark.

The mark awakens when Tanjiro is in danger and when the Sun Breathing technique is used. The scar on his forehead refers to the Demon Slayer Mark, a tattoo or birthmark-like mark that grants the wearer incredible power and ties directly to the Sun Breathing technique. Powering up causes the wearer to be on the same level as the Twelve Kizuki.

4. Muzan’s Search for Blue Spider Lily

Muzan's Search for Blue Spider Lily

It is said that the Demon King Muzan was the first demon to be created. He is in search of the blue spider lily as it will help him gain immortality by making him immune to the sun. There is a belief that the blue spider lily can regenerate itself and be able to create demons.

Muzan is weak and vulnerable to sunlight, which can degrade his body. He killed the doctor who had helped him when Muzan was on the verge of death. Since the doctor was the only one who knew the location of the flower, Muzan set out to find it no matter what.

3. Sun breathing

sun breath

Also known as Hinokami Kagura, it is a breathing style that was one of the first to be created. Yorichi Tsugikuni is the creator of Solar Breathing, and all breathing styles are derived from it by modifying it to meet the needs of all people.

Users of this style imitate the sun and replicate its movement and techniques. All the techniques and forms are different, which makes them very effective against demons. This breath is passed down from father to son in each generation, along with the Hanafuda earrings. Sun Breathing has 12 techniques connected to each form. Later, Yoriichi created a new unnamed technique while he was meeting with Muzan Kibusuji.

The Kamado family has used this technique and Tanjiro is the last user to learn it from his father, Tanjiro Kamado. Tanjiro first used sun breath against Rui during the Natagumo arc. He found that his body was better suited to this breathing technique, as it increased his overall power and speed.

2. Nezuko’s transformation

Nezuko's transformation

There have been various theories as to why Nezuko became a demon and did not join the rest of her family. It was not an intentional move by Muzan, as she wanted to kill the entire family.

Demon Slayer borrows many elements from Japanese mythology and the Shinto religion. In the Shinto religion, ancestors hold an important position, and the Kamado family performs the ‘Fire God dance’ every year as an offering to God. Viewers have pointed out that ancestor spirits may have saved Tanjiro and Nezuko.

1. Tanjiro Hanafuda Earrings

Tanjiro Hanafuda Earrings

The Hanafuda earrings passed down to the male born of the Kamado family through generations after the Hinokami Kagura is quite a mystery. Muzan Kibutsuji looked shaken when he saw Tanjiro wearing the Hanafuda earrings.

Muzan sees a man with red hair and the same earrings from his past, causing him to order his two men to follow Tanjiro. The earrings reminded her of Yoriichi, the only demon slayer who almost killed Muzan.

final thoughts

Demon Slayer has elements of Japanese religion and mythology. As the anime progresses, sharp-eyed fans notice things that others may have missed. These theories help viewers understand why certain characters behave the way they do.

The upcoming seasons will surely contain several other factors that will also give rise to many new theories. We are sure that everyone is holding their breath and eagerly waiting for the anime to be released as soon as possible.
