☆Headcanon: brother-sister coding, hear me out

I need to get this post done before whatever that will happen in chapter 192. So even if I only got two more days for this theory to be around, I'll be glad that I finally let this out from my chest after a while. So, don't take whatever I will ramble about as something super serious.

First of all, maybe you guys will look at me and says, "what the fuck Alie they're like two different unrelated characters" and while that's true for now and so far, I just... can't really took my eyes off from this "siblings coding" the more I read Chainsaw Man. And I have some reasons and theories why (disclaimer: I did a crazy reach all over the direction) and I found it very interesting.

Reason no. 1: Their First Meeting & Re-occurence

Hirofumi is the first part 1 character that Asa meets (even before Denji). So, I think it's reasonable for me—the reader to be intrigued on what is Fujimoto's plan for their seemingly "not important" (but why be the first?) relationship.

My initial thought is that: oh, they might become friendlier in the future or even become lifelong enemies. Then I remember Hayakawa Family—Aki and Power as the first ever Denji's buddy, specific on Power.

Because even though narratively and character writing-wise Power and Hirofumi are fundamentally different, both of them are written initially to form false narratives that they'll become a token love interest for our protagonist(s) aren't they? They also share a somewhat similar strawberry cake motive, makes me wonder why.

Alsoooo, I think the way Hirofumi & Asa's Devil Hunter Club "date" being portrayed as very differently from Hirofumi + Denji and Hirofumi + Fami "cafe date" (a.k.a. work-related mandated date) is important, somehow.

Reason no. 2: Personal Motives and Untold Family Narratives of Asa Mitaka

We know since the very first time we met her that Asa is very lonely and her motives circling around getting a companion (either a boyfriend or a friend) and living selfishly (which as we can see right now is backfired rapidly, but I'll talk about this separately later, maybe in the future).

However, there's one aspect of her motives that's kinda underlooked, and it's her relationship with family member. Yes, we got a glimpse of Asa and her mom (never with her father so far) and Asa with her lovely pet—Crambon, however they already died years ago, and Asa blame herself for it.

It's unfair that in this world, she still had her family, as they said. So maybe she already gives up on that idea. Which is where the true weights of this headcanon come from. What if, she still could have it? Even though she never asked for this directly. Her getting a family again that she was maliciously accused of unfairly having, could be very nice, actually. Even if it's a very insufferable or a miserable mess workaholic kind of brother (or twin brother).

Reason no. 3: Hirofumi's Motives

This deserves its very own post just like my plan to talks more about Asa's living selfishly motive but to make it simple, Hirofumi lied at the very start because he already formed a parasocial relationship with both Asa and Denji by giving them options to have a somewhat nicer normal life (Denji not becoming Chainsaw Man, and Asa making a distance from Denji to prevent her from turning him into her weapon and thus also prevented her to feel down because of the guilt) even though he knows that another choice never really exist to begin with.

(Asa doesn't necessarily have to be his sister to add more depths to this motive. I just think won't it be very funny if Hirofumi was like collecting information all around, confirming that Asa Mitaka is indeed the incarnation of War Devil in weird case then he took a look at her Koseki then boom they have the same dad!? What the fuck was that. Here comes new responsibility that his father left behind, I guess)

As what we know so far, Hirofumi took his job and his responsibility very seriously and very neat about which one he could improve or "change" for everyone's sake involved. IF Hirofumi and Asa are indeed siblings (or half siblings) however, this gives more explanation on his involvement and his own personal interest. Hirofumi is not easy to read, but he still overshares to Asa (chapter 121 when he agrees on Asa's takes about solitude) and "taking care" of her.

Reason no. 4: Just Take a More Look at Them

Taller than average? Check. More athletic than average? Check. Insane face card? Check. Unbelievable amount of yearning? Check. Arguably suicidal? Check.

Both of them being a human stuck in status quo between human vs devil war like hostages in their own prison—Hirofumi stuck as hollow used cop for Public Safety and Asa stuck as War Devil very own vessel—with absolutely nothing, no one really on their side (Fumiko and Fami as mean of even more control over both of them)? Check.

Even as concept alone, child soldier and war maiden incarnate siblingsm could be developed to be something, very interesting.

Okay, now into more theories territory.....

Theory no. 1: Asa and Hirofumi are the Result of Kishibe Fucking Around and Found Out Post Quanxi Rejection Era

Why Kishibe would do that? Idk but it's a funny math because if Kishibe is in his early 50 now then 17 years ago would be him in his 30s. If Kishibe become devil hunter in his early 20s and meet Quanxi shortly after that and become buddies for 9 years then, the year just lined up lmao. How much chances of them being an oopsies baby thus explaining their very different last names but strangely similar physiques and even narratives? Not zero.

There are two options regarding this though. It's either they're twin siblings or half siblings. Half siblings mean they have different mothers but same dad, and twin siblings mean they have same mother but got separated at some point during their lifetime (Hirofumi went with Kishibe and Asa went with her mama who probably re-marry or just simply raising Asa alone and lying about her dad getting eaten by devil or something because her love story with that drunkard crazy man is just that bad).

Kishibe avoiding child support for 17 years and this is the consequences, also both of them got their ass kicked out by the very same lesbian who rejects their father, I'll say it's a beautiful storytelling.

Theory no. 2: Sinister Look on Vol 17 Cover and "Hirofumi will appear in Asa's Dream"

We will get into a more sinister area here because I believe the Makima-esque vibes, "necessary evil" narratives Hirofumi brought up to the table are not coincidences or neglectable at all. Even more sinister because his cover is him standing in front of alleyway just like how Makima cover is her in front of the door in Denji's dream.

Which led me to think that this could indicate something. However, kinda different on how it was portrayed, I think this make things clear that Hirofumi is not endgame antagonist since his cover came a bit too early than what we—the reader anticipated (there is absolutely no fucking nobody in the fandom that expecting Hirofumi to get a cover during before the cover reveal). However, he might be the key into Asa's end dream reveal later on.

Maybe he will appear on her dream being vague as fuck, or maybe direct her dream into a more "false happiness" directions since all he did is lying (see reason no. 3) to distract her focus on dead chickens. Personally, I think the latter will be more interesting because it will be the opposite of what Makima did in Denji's dream, if this "Hirofumi will appear in Asa's dream sooner or later" theory is true. The government and the church need Asa in her stable conditions to unleash Yoru anyway.

"Then what does this imply into your siblings theory"—because siblings should take care of each other, ideally. And I think it will add more depth, if true of course.

Theory no. 3: Hirofumi Cares About Asa (maybe more than what we see on-screen)

To put on more disclaimer, this is just what I imagine to fill out the gap in between narratives and it connects to reasons number 3 (again). Despite how he positions himself and blending in the crowd like invincible, Hirofumi is actually easy to care and feel guilty too (and the reason why he could kill the Immortal Brother assassin in part 1 is because he has the ignorance privilege, but with both Denji and Asa? Not so much).

I have no strong basis for this theory I just have my own feelings and a dream, and this is basically what I think Hirofumi has done so far for Asa (subtle) in the story:

Hirofumi just let Yuko loose and kill Asa's bullies during Justice Devil Arc. This may sound dark, but it fit his character in a way that he's okay with doing violence as long as it could benefit his mission (and maybe this time his personal interest too). Because he knows Asa got bullied at school. If this could solve her bullying problems, then why not? That's why Hirofumi is just sitting around during the whole fight until Denji interfered.

Hirofumi is the one who brought Asa to hospital after Falling Devil Arc (which is somehow in line for how I think he's Denji blood-giver in the same arc). Because well, I don't think Public Safety cared enough to get her conditions checked, but Hirofumi is aware about her injury conditions (arguably this is so that she could be a bargaining chip for Denji but we know that the main chip is Nayuta, I think Hirofumi just want to let him know just because also let me have this imagination for the sake of this agenda).

The reason why Hirofumi didn't or more likely can't kill Asa during CSM Church Arc is not necessarily just because War Devil has become stronger. Paneling focus on their face's expressions indicate that Hirofumi just can't bring himself more to do so (after he saw Asa's hand and her in pain), thus making him fail this mission to capture War Devil dead or alive. It's the guilt kicking in.

I think Hirofumi is somewhat relieved after he saw Asa's hands are back (yay) in Aging Devil Arc. Also, that's what he put his focus on FIRST after he got vomited out before asking his own situation even.

Personal View and The Main Takeaway (really): I need this to be real just because I think it will be so fucking funny

To end this unbelievably long ass post, I think it's important to note again that they have like five screentime together and I'm just insane. But if I should be honest, this is not me being rational at all, I just think the whole situation would be funny up to seven more factors if my ramblings are true.

Because this headcanon imply that the fandom meltdown towards them (as individuals or as in characters dynamics) is unnecessary at all. Like aside from Hirofumi being read mainly as queer, maybe him acting kind of mean and nonchalantly distant (and somewhat awfully playful) towards Asa are just because he like being petty and doesn't want to look like he wants to bang his sister (as a sister myself, yes I do feel the need to annoy my other siblings whenever I can just because I could and it doesn't have to be hatred, sometimes it's the love aggression kicking in).

Lastly, thank you guys for coming to my yapping ted talks.
