Not a fan of how ending was executed, power ups etc all that, I'm alright with characters dying it's kinda expected at with how things were going. But I really think the series needed to be longer, the cut to the ending was way too fast imo, and there wasn't enough time or story for me personally to feel somewhat attached to most of the pillars etc. Some of them sure it was pretty sad to see go and die but the main 3-4 (Tanjiro, Zenitsu, Inosuke, and Nezuko) are still alive and theyre the only ones I really cared about which is fine, if any of them had died I certainly would have been sad. Kinda felt like they just wanted to end it without knowing how. Whatever though, it was an enjoyable read, will wait for the final chapter and read it happily. But im positive that after a full re-read Ill enjoy it more.
Feels like after Tengen and Uzui there was just not enough time to progress or feel connected to the other pillars, (except maybe Himejima cause he's a baller and his story was pretty sad)
