psych! Nothing gets resolved and all plot points end on a cliffhanger
We got resolutions to the major plot threads though. at least all the ones in pt. 2, and vague allusions to Denji feeling bad about not going to look for Power.
Fire Devil stuff: just wanted Denji to choose between Normal Life and Being Chainsaw. Did literally everything to achieve this.
Asa/Yoru stuff: Asa had a shit upbringing, but she was just a normal girl, Yoru had no connection to her backstory. The bird really was just a bird. All the fan theories were wrong.
Asa and Yoru have irreconcilable moral differences.(may get wrapped up next chapter), but their arc ended when Yoru basically said "dude im a devil lmao idc about your morality" (imo this reflects irl failed relationships/friendships)
Control Devil stuff: Nayuta is literally dead. Barem killed her for the Fire Devil to traumatize denji, she's not coming back. Devilman reference.
Death/Prophecy stuff: Death was just pretending to be famine devil, there was nothing deeper going on. Gets eaten by pochita unceremoniously. Denji-Man is the King Of Terror and the prophecy came true, the world ended.
Part 1 stuff: Makima was just a schizo, the followers of Pochita aren't really angels. Denji feels vaguely bad about not looking for Power but he wants to goon, so fuck it lmao. Quanxi is still around. Kishibe probably fucked off. Reze got ignored. lol.
What else has got to be wrapped up? The only thing I'd want more clarity on is Asa/Yoru's relationship but that could get resolved in literally one page(Asa: "fuck you lmao but thank you for teaching me to be more selfish" Yoru: "dude I'm a
NIGGER DEVIL lmao")'
Oh, I guess the "devils hear a chainsaw when they're born" thing never got explained but I always figured that would never be explained and was more of a facet of Chainsawman always fighting in Hell before he met Denji so devils would hear him as they spawned in.
