20 Best Aki Hayakawa Quotes — Chainsaw Man's Doomed Devil Hunter (2026)
Aki Hayakawa is what happens when a story refuses to let revenge feel good. His family was murdered by the Gun Devil when he was a child, so he signed his lifespan over to two devils — the Curse Devil and the Fox Devil — for the chance to kill it. Tatsuki Fujimoto then spends a hundred chapters showing Aki that every step of the bargain costs more than he expected, and that the people he comes to love (Denji, Power, Himeno, Angel) cannot survive in the world the bargain put him in. By the time the Future Devil promises him “the most wonderful future imaginable,” readers already know the punchline.
These 20 chapter-cited quotes follow Aki through the squad room banter, the smoking-on-rooftop scenes with Himeno, the ghost of Master Kishibe’s training, and the slow walk into Makima’s plan. He is the most adult character in Chainsaw Man — and the manga’s clearest argument that adulthood does not save you.
About Aki Hayakawa
Aki Hayakawa is a major character in Chainsaw Man (2018-present) by Tatsuki Fujimoto. A Public Safety Devil Hunter in Tokyo Special Division 4, he is Denji’s senpai, Power’s reluctant babysitter, and the squad’s responsible adult. As a child Aki’s parents and younger brother were killed by the Gun Devil — the manga’s most powerful and feared devil — and he has trained his entire life to take revenge.
To get strong enough, Aki has signed contracts with multiple devils. The Fox Devil lets him summon a giant fox head to eat enemies. The Curse Devil, sealed in a wrapped katana, kills a target instantly at the price of years of Aki’s own life. Later he is forced to take the Future Devil contract, which shows him only one vision: his own gruesome death. Across Part 1 he serves under Makima, mentors Denji, partners with Himeno (smoker, lover, soon-dead), trains under Kishibe, and gradually realizes that everyone around him is being used.
His signature: short black hair pulled into a small ponytail, suit and tie, cigarettes, the Cursed Katana wrapped in talismans, and the Fox Devil’s fanged jaws materializing from thin air at his command.

Why These Quotes Resonate
Fujimoto frames Aki as the responsible adult and then makes adulthood the trap. Aki signs contracts, takes the job, follows orders, mentors a child — all the things a “good” character does in a normal shonen — and every single one of those choices is what kills him. The Future Devil’s promise of a “wonderful future” is a punchline that takes the whole series to deliver: the most wonderful future Aki can imagine is the one where Denji ends him before he becomes the Gun Devil’s puppet.
That’s why Aki’s quotes hit so much harder than his page time suggests. Every responsible-elder line (“Quit Public Safety, Denji”) is also a dying man begging a child to escape the system that killed him.
Frequently Asked Questions about Aki Hayakawa Quotes
What is Aki Hayakawa's most famous quote?
"I'll kill the Gun Devil. After that, I don't care what happens to me." That line, delivered early in Part 1, is the thesis of Aki's whole arc — and Fujimoto's setup for the tragedy. By the time the manga grants the wish, Aki cares very much what happens to him, because by then he has Denji, Power, and Angel. The revenge plot has outlasted the boy who started it.
What contracts has Aki Hayakawa signed?
Three are explicitly shown: the Fox Devil (a giant fox head he summons to eat enemies), the Curse Devil (the wrapped katana, which kills an enemy instantly at the cost of years of Aki's lifespan), and the Future Devil (which lets him glimpse the future — at the price of seeing only his own death). Each contract trades life for power, which is the manga's clearest statement about what revenge actually costs.
Why does Aki Hayakawa want revenge on the Gun Devil?
The Gun Devil killed Aki's parents and younger brother when he was a child. In Chainsaw Man's world the Gun Devil is the single most-feared devil, responsible for over a million deaths globally, and most of its body is held in pieces by world governments. Aki joined Public Safety at the only age law allowed, signed every contract that would make him stronger, and built his entire adult life around the chance to find and kill it. The tragedy is that the chance arrives at the wrong angle.
Does Aki Hayakawa die in Chainsaw Man?
Yes — and the manner of his death is the most-debated moment of Part 1. The Future Devil's vision turns out to be Aki being possessed by the Gun Devil's fragments and forced to fight Denji. He dies by Chainsaw Man's hand. Fujimoto frames this as the "wonderful future" the Future Devil saw: Aki's last seconds are with the person he came to think of as family, who finally gives him an end he can't ask for any other way.
Who trained Aki Hayakawa?
Kishibe — the strongest devil hunter in Public Safety, head of Special Division 1 — trains Aki (and Denji, and Power) in the back half of Part 1. Kishibe's lesson is the rule that defines Aki's adulthood: "Never trust anyone." It's a rule Aki tries to obey and quietly fails at, because he has already let Himeno, Denji, Power, and Angel become people he would die for.
