One thing I never expected for this chapter spoiler is "Tanjiro dead" I can accept him dying and its not impossible since the mangaka seems to have a knack for killing its characters, but Tanjiro has barely done anything to Muzan yet besides that sword throw to his head from the prev chapter, too many mysteries remain, we still have no idea what the 13th "Fire Breath" is, I can't see anyone besides Tanjiro being able to pull it off. No way the author would have its MC die like that without leaving any huge impact. Killing Tanjiro right now won't give this manga any unique breaking the mold kind of thing, it'll just make it have an MC that had an anticlimactic/disappointing death. It wont do the manga any good.
This sorts of so called "death" of the MC happens in most shonen anyways.
Goku,Yusuke,Ichigo,Naruto,Meliodas and one series I dont even wanna mention anymore because of how offensive it was.
That being said.. look at that page, Tanjiro looks gruesome af.
We read/watched this boy grow since chapter 1, aint no way he dying like this. That aside I am not a fan of this whole idea where Tanjiro gets Yusuke'd, y'know... him becoming a demon.
