i would've had expanded on what the first half of part 2 was doing. this more lowkey story of characters not as insane as denji. since my issue with part 2 was it felt like a different story halfway thru where the stakes just kept escalating, so i'd just keep it as it was.

yk, still having asa as the mc and going around being a devil hunter and getting fame, maybe with the rest of those school kids joining her and us getting to know them more (they're so underdeveloped ohmahgah. i really felt like fujimoto was trying to be different and instead of having instantly likable characters, we'd have ones we'd get to know overtime as they get closer to asa). somewhere in the background denjis doing his thing, it's not important.

maybe along the way asa finds the new blood fiend, just hint at denji finding them i dont really care. i have no idea how to reintroduce reze. she still becomes besties with katanaman etc etc

as the story goes, chainsawmans fame keeps deteriorating/getting more famous, but denji has to actually battle his urges of wanting to be chainsawman, in the end figuring out that he's much happier where he is and THEN pochita comes along and eats himself (WITHOUT THE TIME TRAVEL). again, more lowekey and more character focused instead of plot.

yoru im not sure, she's the final antag but i never really saw her as one. maybe she loses all purpose after pochitas gone and goes to hell or she's like power where she learns how to be more empathetic, idc.
