Conversation-Starters with Demon Slayer Trivia & Fun Facts (1–10)
Doma became a demon after Akaza, but he holds a higher rank than Akaza.
Akaza and Doma are both Upper Rank demons, but Akaza is Upper Three while Doma is Upper Two, so Doma outranks him.
In general, a demon’s strength is said to depend on the number of humans they’ve eaten, and Doma prefers to eat women.
He said Akaza is weaker because he refuses to eat women, who provide more nourishment.
Since Akaza was obsessively devoted to strength, it must have been galling for him to lose to Doma, who became a demon after him.
Also, because of Doma’s personality, he embarrasses Akaza without any ill intent, so it’s understandable that Akaza dislikes him.
Tanjiro Kamado saw the Blue Spider Lily when he was a child.
The Blue Spider Lily is the source of the special medicine Muzan Kibutsuji searched for to overcome the sun.
He had the demons under his control look for it as well, but it was never found.
However, the official fanbook revealed that Tanjiro has seen the Blue Spider Lily.
Aoi-e, Tanjiro’s mother, knew where it bloomed and showed it to him when he was a child.
The place where the Blue Spider Lily blooms is said to be where Uta, Yoriichi’s wife, is buried.
If this is close to Tanjiro’s family home, then it means Muzan came quite close to the Blue Spider Lily.
Blood that is especially nutritious for demons is called ‘rare blood.’
Demons primarily feed on humans.
Among them, the most prized are humans with rare blood.
It’s said that a person with rare blood has the same nutritional value as eating 50 to 100 ordinary humans.
In the story, there was also a boy who was abducted by demons because he had rare blood.
He himself isn’t aware of it, so if a demon finds him, he’ll be eaten right away.
If you don’t have the strength to defeat demons, it’s recommended to carry a sachet with the scent of wisteria flowers, which demons dislike.
In fact, there’s even someone among the Pillars who possesses this rare blood…
Akaza is a demon, but he neither eats nor kills human women.
Although demons primarily feed on humans, Akaza was unable to harm women and refused to eat them.
According to Doma, another Upper Rank demon, even Muzan Kibutsuji permitted this.
When Akaza was human, he had promised to marry a woman.
She was killed by poison, and he deeply regretted failing to protect her.
Though Akaza no longer retains that memory, his inability to kill women is likely connected to that past.
His aversion to Doma may also stem from the fact that Doma prefers to eat women.
Kibutsuji Muzan and Ubuyashiki Kagaya belong to the same clan.
It is known that Muzan Kibutsuji, the progenitor of demons, and Kagaya Ubuyashiki, the head of the Demon Slayer Corps, belong to the same clan.
Because a demon emerged from their lineage, children of the Ubuyashiki family could no longer live long.
They seem to have extended their lifespan by taking wives from a family of Shinto priests, but even so, all the sons died save for one, and the daughters would die unless they married and changed their surname by the age of thirteen.
To break this curse, each head of the Ubuyashiki family has been charged, generation after generation, with defeating Muzan Kibutsuji.
Giyu Tomioka’s haori is a keepsake and a memento left behind.
Giyu Tomioka’s haori is an heirloom and memento, depicted alongside episodes from his past.
Its hallmark is the two different patterns split down the middle—a haori that combines keepsakes of his older sister, Tsutako, and his close friend, Sabito.
His sister was killed by a demon, and his fellow trainee Sabito lost his life during the Final Selection, so you can feel his resolve to carry the weight of their lives.
The haori conveys Giyu’s character—his determination not to forget what led him to aim for the Demon Slayer Corps and the path he took to get there.
Shinobu Kocho once burned the uniform she was given.
This is an episode included in volume 12 of Demon Slayer: Kimetsu no Yaiba.
Shinobu’s uniform has the same design as the male Corps members’, but Mitsuri’s uniform has a skirt and a top with a deeply open neckline.
Apparently, Shinobu was originally given the same uniform as Mitsuri’s.
However, she burned it right in front of the member who handed it to her.
It was almost certainly an angry statement that she would never wear it.
Because of that, Shinobu ended up with the uniform she has now.
By the way, the uniform was made by a Corps member named Maeda, nicknamed “Gese-Megane” (the Sleazy Glasses).
