Chainsaw Man: The Fire Devil's host isn't who you think

Following the latest release of mangaka Tatsuki Fujimoto’s Chainsaw Man series, fans are focused solely on who the Fire Devil’s host is. Understandably, many are asserting it to be Seigi Akoku given the plethora of evidence which would suggest this. Others are instead asserting it’s Haruka Iseumi, given his character design and overall fanaticism of the titular hero.

Still others are suggesting it will be a brand new character for fans who has never been named or featured in any prominent way before. However, a small portion of the community is asserting that it is a minor unnamed character whom fans have seen before. This would be the young student whom Denji chose not to save in order to prevent a stray cat’s death.

While seemingly one of the weakest options Chainsaw Man fans have currently come up with, there is a good argument for this being the case. Firstly, the silhouette of the Fire Devil host’s severed head matches up with this minor character’s design and appearance. There is also the fact that the way in which he died is very similar to the host’s head facing Denji in chapter 204.

This minor character was also classified as an aspiring student by the Cockroach Devil as it forces Denji to choose who to save. Yuko previously confirmed that the Justice Devil, which is the name the Fire Devil hid behind, was at their school. With the most logical conclusion being that they’re a student, this is yet another similarity which lends credibility to the theory.

Another key piece of evidence is that, as this unnamed character died, a car was seen burning behind him. This would obviously evoke the sense of the Fire Devil watching over him. Chapter 103 also saw the metaphorical fire start for Chainsaw Man’s popularity. With the Fire Devil being heavily linked to the idea of fire as passion, this would be yet another major piece of evidence.

This would also explain why Fakesaw Man’s personality changed so greatly from prior to confronting the titular hero to actually meeting him. In the former, he wanted to take Denji’s heroic identity from him and play the hero. However, upon actually confronting Denji in his transformed state, he was overcome with rage at being left to die while a cat was saved.

One of the biggest arguments against this theory is it being predicated on the fact that this minor character became the Fire Devil’s host after dying. One can argue this wouldn’t explain how characters like the class president were able to contract with the Fire Devil. However, it is entirely possible that the class president contracted with Fire directly rather than through their host.

This character being the Fire Devil’s host would also fit with a running theme in Part 2 of Denji choosing his own, third path. His doing so after Yoshida ordered him to stop being Chainsaw Man is one of the most prominent examples of this. Likewise, Denji choosing to save the cat rather than the student or the car of old ladies in chapter 102 would see this behavior punished once more.


Final thoughts

While the above theory is far from the strongest the Chainsaw Man fandom has offered, it has incredible narrative significance. There is also an argument against its biggest flaw in the timeline of Part 2’s events which lends it further credibility. Thankfully, fans won’t have to wait too long, with the host’s identity likely to be revealed in chapter 205 on Tuesday, June 10.
