Demon Slayer: Kimetsu no Yaiba

Everything About Fiction You Never Wanted to Know.

A 2016 manga by Koyoharu Gotouge, Demon Slayer: Kimetsu no Yaiba(Kimetsu no Yaiba, literally Blade of Demon Destruction), is the tale of a charcoal seller and his hot sister.

Tanjiro Kamado is just a poor coal seller living a mountain on Japan. His relatives and neighbors tell him scary stories about onis, aka demons, human-eating creatures who walk at night, but Tanjiro doesn't believe on them. However, one day, arriving late at his home after selling charcoal because a neighbour advised him to not walk outside at night, he finds his family slaughtered, presumably by demons. His sister Nezuko, however, is still alive.

While taking an unconscious Nezuko to the nearby village, however, Tanjiro is attacked by Nezuko, that is revealed to have been turned into an oni. A demon hunter appears and tries to kill Nezuko, but Tanjiro resists and when said demon hunter tries to stop Tanjiro so he can stop interfering, Nezuko rushes for his aid, a behaviour the demon hunter considers a proof she still has some of her human nature and isn't a complete demon yet. Revealing his name to Tanjiro as Gyuu Tomioka, he tells Nezuko and Tanjiro to seek the help of an elder called Sakonji Urokodaki, that lives on the bottom of the mountain.

After paying respect to their dead family, Nezuko and Tanjiro departs to the bottom of the mountain, with Tanjiro hopeful that Nezuko can be cured of the condition of being a demon.

Serialized on Weekly Shounen Jump.Published by Shueisha.

Tropes used in Demon Slayer: Kimetsu no Yaiba include:
  • The Call Knows Where You Live: Tanjiro never dreamed of being a hero, or even think onis were real, and was perfectly content with being a charcoal seller, but then demons attacked his home and killed most of his family.
  • Dude Looks Like a Lady: Though his physique gives away his gender, Inosuke is noticed by several characters to look pretty much like a girl thanks to the curves of his face.
  • Exclusively Evil: Demons are heavily implied to be this because Gyuu was willing to kill Nezuko on the spot, though the fact she was attacking Tanjiro didn't help. She of course immediately averts this trope.
  • Fan Disservice: Nezuko in a kimono and with her legs and thighs exposed in Chapter 1 should be an alluring sight, but the blood all over her mouth and her unnaturally grown fangs detract away from it.
  • Healing Factor: Demons have that, all of them. That is why using sunlight or special swords to decapitate them is the only method to kill them.
  • Hero Antagonist: Gyuu just wanted to kill Nezuko because demons are Always Chaotic Evil, and therefore he saw no choice but to kill her to save more lives. Once he sees she retains part of her humanity, he ceases to be an antagonist and guides Tanjiro and Nezuko.
  • Horror Hunger: Onis/demons are said by Gyuu to develop quickly a hunger for human flesh that can only be placated by consuming it. Nezuko being able to overcome those instincts to hunt humans to protect Tanjiro is something Gyuu is surprised at seeing.
  • Mutual Kill: Gyuu realizes in Chapter 1 after defeating Tanjiro non-lethally that the boy's plan to defeat him hinged on this, with Tanjiro being decapitated and a distracted Gyuu being hit by an axe that was falling towards him.
  • The Not Love Interest: There is no question Tanjiro would move heaven and earth for Nezuko, that he deeply loves her and, humorously, he is furious at the idea anybody would think of her as ugly, finding her extremely beautiful. But she is his sister, so all of those feelings are strictly platonic.
  • Our Vampires Are Different: Onis are killed by sunlight, feed on humans, and can convert others into one of them by having their blood enter their victims.
  • Thou Shalt Not Kill: The demon hunters apply this policy to humans. Gyuu doesn't lethally attack Tanjiro even if the boy was helping some demon clearly hungry for prey, what ends up saving Gyuu and Tanjiro's lives.
  • Training from Hell: To start Tanjiro's training on demon-slaying, Sakonji makes him climb down a mountain while trying to escape from painful traps, so Tanjiro learns how track him by scent.
  • Wearing a Flag on Your Head: Tanjiro's default outfit include earrings with the Rising Sun, the naval flag of Japan.
