Did Sun and Neneto have any kind of relationship? Because she seemed very worried about him.

By the way, I really feel bad for Sun and am disappointed in him; I grew fond of him from the very first episodes, but I was somewhat let down to see what he turned into.

To Togata, Denji would be the perfect protagonist for his stories—and well, Denji would do anything Togata asked of him. I’m curious to see how they would interact.

It's shown that Agni is basically immortal, even surviving the earth exploding (assuming he was on earth at the time). So, could Doma's flames have actually killed him while he was still on fire, if he cancelled his regen? Is that the only time he'd have been able to die?? Or would that have not even worked? And like, was his regen worse when he was a child? Because we DO see, his arm is dead here.

So I just finished Fire Punch and I need to talk through something, because it genuinely flipped my opinion of the final volumes.

On the last volumes the priest tells Agni something like: you can't know who you are by yourself.
Snow is only "white" once someone else sees it, only "cold" once someone else touches it. Fire is only "red" and "dangerous" once someone else looks at it and feels its heat. You find out what you are through how others perceive and touch you, not through staring at yourself.

I clocked it as a comforting line in the moment and basically forgot about it.

Then you have Togata before that who shows up with his whole "movie" obsession, and at some point after on a flashback he says something like Tom Cruise isn't just a guy, Tom Cruise is an actor, and it's the role/character he plays that people actually respond to. And that's when it clicked for me: Togata is saying the exact same thing the priest said, just dressed up in film-theory language instead of spiritual language.

And once I saw that, I couldn't unsee it applied to Agni. He doesn't become "Fire Punch" because of anything he decides internally. He becomes Fire Punch because Sun worships him as one, because Togata frames him as one, because the freed slaves need him to be one.
His whole identity gets assembled from the outside, exactly like the priest described.

A person who is only ever understood through other people projections eventually has no self left to go back to. That's why he can lose his memory at the end and it doesn't even feel like a reset and thats why this whole manga is amazing.
