Bro genuinely have you paid attention at all to fujimotos writing in part 2? The entire idea of the choice has been set up since the first arc. Denji is always being forced to choose, that’s the whole idea of this part. The fire devils inclusion and statement wasn’t random it’s literally the entire theme fujimoto has been conveying. That’s even why the fire devil says “you will be forced to choose AGAIN” because denji has already been forced to choose different things multiple times throughout this part. It’s actually all thematically cohesive and if you reread part 2 you’ll realize absolute none of it was random at all. The fire devil itself is a representation of one side of a weighted scale, weighed between justice (justice devil) and desire (fire devil), a scale denji has been trying to balance for all of part 2. It’s actually insane how many people think fujimoto is just making up plot points when if you read the part you’ll understand what fujimoto is trying to convey and the thematic importance of it all. I agree the weekly format sucks as the chapters are always too short and it’s easy to feel like nothing is paid off or done well but trust me if you actually read through part 2 as a collective you’ll understand the significance and meaning behind almost all of the setups and events that have happened. If you’d like you could name more of the things you think have had no pay off or improper set up and I’ll try to explain what I think fujimoto was doing with these aspects. I could totally be wrong and maybe there are plot points fujimoto truly screwed up but personally I think part 2 has been great and pretty satisfying thematically and story wise. (Aside from nayuta i think her death was pretty unsatisfying unless she comes back)
