The Haunted Hunter's Genesis: Aki's Path to Vengeance
From the moment we meet him, Aki Hayakawa is defined by a singular, burning purpose: revenge. As a young boy, he suffered an unspeakable tragedy when the Gun Devil annihilated his family, including his younger brother, Taiyo, leaving him as the sole survivor. This catastrophic loss forged an unyielding resolve within him, driving him to join Public Safety as a Devil Hunter. He was willing to pay any price, sacrifice any part of himself, to track down and destroy the entity that stole his innocence and his loved ones.
Initially, this pursuit made him cold, blunt, and seemingly unfeeling, especially towards newcomers like Denji, whom he viewed as immature and driven by frivolous desires. Yet, beneath this hardened exterior lay a deeply compassionate and easily attached individual, a trait Himeno, his first partner, recognized and cherished.

The Form of a Fighter: Aki's Striking Appearance
In his human form, Aki cut a striking figure within the Public Safety Devil Hunters. Tall and handsome, he was instantly recognizable by his medium-length black hair, meticulously styled into a topknot—a detail that subtly hinted at his disciplined nature. When untied, his hair reached his shoulders, framed by long bangs. His piercing blue eyes often conveyed his stoicism and the heavy burden he carried. He consistently wore the standard Public Safety uniform: a sharp suit and tie, accessorized with black earrings and a katana strapped to his back, signaling his primary weapon and role.
However, Aki's physical appearance undergoes a terrifying and tragic transformation in the later stages of his story, evolving into something far removed from his human self. To —both as a human and in his horrifying post-mortem form—is to witness the full scope of his journey.
A Heart Beneath the Ice: Personality and Growth
Aki's initial presentation was that of a stoic, mature, and often rude individual, particularly towards those he deemed unprofessional or childish. He harbored a profound disdain for Devil Hunters who worked for superficial reasons, contrasting sharply with Denji's simple desires. Yet, his cold demeanor was a mask for a genuinely softhearted person who grieved deeply for the lost and formed strong attachments. He wasn't jaded by the horrors he witnessed; instead, he carried the weight of them.
Over time, living with Denji and Power chipped away at his icy facade. His relationship with Himeno, his dear friend and partner, was a testament to his capacity for deep connection. As he spent more time with his unconventional "family," his priorities began to shift from pure revenge to protecting those he cared for, especially after the Future Devil showed him a terrifying vision of their demise. This fear of losing Denji and Power even made him consider abandoning his life's mission. His evolution in viewing devils, from mere tools to beings he could care for—like the Angel Devil, for whom he sacrificed part of his lifespan—showcased his profound empathy. To , from his initial vengeful drive to his eventual loving nature, is to witness one of Chainsaw Man's most compelling character arcs.
The Devil's Bargains: Aki's Contracts
To achieve his goal of vengeance, Aki didn't shy away from making contracts with several devils, each coming with its own fearsome power and a steep price. These pacts were not merely tools but critical reflections of his desperation and willingness to sacrifice.
- Curse Devil Contract: This contract granted Aki a nail-like sword. By touching an opponent with it and uttering "fire," he could inflict damage. For a more devastating, potentially lethal attack, he could stab an enemy three times with the nail, summoning the Curse Devil's hand for a massive blow, though this significantly shortened his lifespan.
- Fox Devil Contract (Former): Early in the series, Aki could summon the Fox Devil's head by offering a part of a devil's body and saying "Kon." The Fox Devil would then bite or swallow targets. He eventually lost this contract due to reckless over-reliance during a fight with Katana Man.
- Future Devil Contract: After losing the Fox Devil, Aki made a new contract with the terrifying Future Devil, which took residence in his right eye. This pact granted him precognition, allowing him to see a few seconds into the future. This ability dramatically enhanced his combat prowess and saved his life countless times, though the Future Devil itself was a chilling presence.
- Control Devil Contract: In a desperate attempt to gain power and save his friends from the Gun Devil, Aki eventually made a contract with Makima, who was secretly the Control Devil. This contract entailed surrendering his entire being to her, effectively making him her puppet and preventing him from utilizing any of the Control Devil's own vast powers.

- Denji: Their relationship began with animosity and disdain, but through shared experiences, dangers, and living under the same roof, it evolved into an unbreakable bond of brotherhood. Aki grew to care deeply for Denji's safety and well-being.
- Power: Initially disgusted by her crude behavior, Aki eventually softened towards Power, viewing her as an irritating but beloved younger sister figure whom he felt compelled to protect.
- Himeno: His first work partner and dearest friend. Himeno saw past his stoic facade and understood his gentle heart. Her death profoundly affected him, fueling his resolve and grief.
- Makima: Aki harbored deep trust, admiration, and even affection for Makima, though this relationship was tragically manipulated by her control powers, as she viewed him primarily as a tool for her own ambitions.
- Angel Devil: Their partnership started with difficulty due to Angel's power to shorten lifespans with touch. However, they developed a mutual care and respect, with Aki even sacrificing two months of his own lifespan for Angel's sake.

The Tragic End: From Hunter to Fiend
Aki's journey culminated in one of Chainsaw Man's most devastating arcs. Through Makima's cruel manipulation, he was ultimately killed by the Gun Devil and, in a horrifying twist of fate, possessed by 20% of its power, transforming him into the Gun Fiend.
His appearance radically shifted: his signature topknot was gone, his hair now let down, his face and eyes covered in dark, menacing veins. The barrel and slide of an M1911 pistol protruded from his forehead, while his left forearm was replaced with a fearsome M16A1 rifle. As the Gun Fiend, his abilities were terrifyingly enhanced: he gained immense Physical Prowess, including Enhanced Durability (his forearm gun could block Denji's chainsaws) and Enhanced Speed. His most potent ability was Bullet Projection, allowing him to fire a torrent of bullets with incredible precision and speed from the guns on his head and arm, capable of leveling multiple buildings. He could also perform Blood Consumption to restore his health.
In his final, heartbreaking confrontation with Denji, the Gun Fiend's distorted mind perceived their brutal battle as a joyful snowball fight with his beloved younger brother, Taiyo—a cruel echo of his deepest, most cherished memories. This final scene, steeped in tragic irony, cemented Aki's place as one of the most emotionally resonant characters in the series.
