* BittersweetEnding: [[spoiler:Muzan and most of the other demons (except for Tamayo and Yushiro) are now dead and nearly everyone survives their canonical fates, but Tanjiro is revealed to have become a demon just like in canon and kills himself to stay human and be with the rest of his mostly dead family.]]

The webcomic loosely adapts the source material, the main difference being that Tanjiro Kamado becomes the Black Swordsman that [[HorrifyingTheHorror terrifies even demons]] after losing not only most of his family but [[DisabledInTheAdaptation also his eye and arm]]. And gone completely [[Ax-Crazy insane]].

* AdaptationalJerkass: Tanjiro lacks the defining compassion of his canon counterpart, physically or emotionally torturing demons without remorse. The Pixiv version even has him say self-righteously that death means salvation for demons after killing Nakime while his canon counterpart prays that one of the demons he kills won't become a demon again in the next life.

* UsedToBeASweetKid: Tanjiro in this webcomic was once one of the nicest people out there, but after Muzan killed most of his family in front of him, turned Nezuko into a demon, and crippling him when he took both his right eyes and left arm away, he's now a [[Manga/{{Berserk}} Guts]] complete with being a Jerkass, having a prosthesis left arms, and wielding a massive sword. [[spoiler: Oh, and he became a demon too.]]
* WouldntHitAGirl: In the Pixiv version, Akaza refuses to help Tanjiro and Muzan against Nezuko because of his code against harming women. Unfortunately, this what got him killed.

It is serialized on Website/{{Twitter}} and later Website/{{pixiv}} since [[https://twitter.com/osker0190/status/1252529411837943808 April 21, 2020]]. Osker originally scheduled the webcomic to [[https://twitter.com/osker0190/status/1267399044449439744 end with a total of twenty-two chapters]]. [[https://twitter.com/osker0190/status/1271361156880322561 But now it will probably end at a total of twenty-four chapters now due to underestimating the length to complete it.]]

The pixiv version even has him say self-righteously that death means salvation for demons after killing Nakime while his canon counterpart prays that one of the demons he kills won't become a demon again in the next life.

** In the pixiv version of Chapter 11, Tanjiro kills Nakime by stabbing her in the back rather than by decapitation, the latter of which is one of the only ways to kill demons.
** The pixiv version of Chapter 19 reveals that Nezuko has killed Kokushibo just by punching him in the face.

* DemotedToExtra: Sabito is one of Tanjiro's mentors in the original manga. The pixiv version of the webcomic, however, demotes him to a cameo since Tanjiro is much stronger than his manga counterpart.

** In the pixiv version of Chapter 11, Tanjiro kills Nakime the same way Sephiroth does to Aerith in ''VideoGame/FinalFantasyVII''. Doma tells him afterward, "[she] will no longer talk, no longer laugh, cry... or get angry... What about me... what am I supposed to do? What about my pain?".
** In the pixiv version of Chapter 18, Kokushibo screams at Tanjiro, Muzan, and Akaza "InTheNameOfTheMoon, I will punish you all! Moon Prism Powerrrrrr?!!", referencing the {{Catchphrase}} and transformation phrase of ''Manga/SailorMoon''.

** Kokushibo does this when he first learn Tanjiro is wearing the Armor of the First Swordman and remember ''himself'' being the one who helped design it.

* AdaptationalNiceGuy: Muzan starts out as the same monster as his canon counterpart, not only killing most of Tanjiro's family in an attempt to make more demons but also taking his eye and arm away. However, Tanjiro nearly killing him in Asakusa and successfully killing most of the Upper Kizuki humble him enough that he lets go of Kokushibo and Akaza, the only remaining members of the entire Twelve Kizuki, and thanks them for serving him for a long time.

* EyeScream: Muzan transfers his blood to Tanjiro, destroying the latter's right eye. [[spoiler:The final chapter reveals that Tanjiro has regained his right eye, though it has a slit pupil instead of a normal one.]]

->'''Giyu Tomioka''': Dear Sakonji Urokodaki, I have sent you a boy who wants to be a demon slayer. A demon murdered his family, took away his eye and arm, and turned his sister into a demon. She didn't attack humans, and the boy rejected the blood Muzan injected into him. But...\\

* AxCrazy: Seeing your family getting killed, losing both your left arm and right eye, and having your sister getting turned into a demon by Muzan does [[SarcasmMode wonders]] to your [[SanitySlippage sanity]]. Ask Tanjiro. And bonus point for him actually wielding an ax in the first chapter too.
