Aki begins as a reclusive, revenge-obsessed individual, but through his relationship with his squad, he learns to value life and connection over vengeance, ultimately accepting his fate to protect his new "family".

Aki Hayakawa, a Public Safety Devil Hunter in Chainsaw Man, is a master swordsman skilled in hand-to-hand combat who utilizes contracts with the Fox, Curse, and Future Devils. His arsenal includes summoning the Fox Devil for quick kills, a nail sword for fatal Curse Devil attacks, and, most notably, precognition to foresee enemy moves.
Key Abilities and Contracts
Future Devil (Precognition): After allowing the Future Devil to reside in his right eye, Aki can see 4-5 seconds into the future, allowing him to anticipate enemy attacks and plan strategies, as explained by Lccomicsnew Wiki and Chainsaw Man Wiki.
Curse Devil (Death Manipulation): By stabbing an opponent three times with a specific nail-shaped sword, Aki can summon the Curse Devil to cause massive, often fatal, damage, though this significantly shortens his lifespan.
Fox Devil (Summoning): Aki can summon the head of the Fox Devil by saying "Kon," allowing it to bite and devour targets. This ability was lost after overuse against the Katana Man.
Weapon Mastery: Expert in wielding swords and knives, often using them for precision attacks.
Physical Conditioning: Possesses peak human strength, agility, and durability, and is trained in hand-to-hand combat, note VS Battles Wiki and Fandom.

As the Gun Fiend, Aki's body is taken over by the Gun Devil, granting him:
Bullet Projection: Aki can fire powerful, rapid-fire bullets from a gun protruding from his left forearm and head.
Enhanced Speed/Destruction: Capable of high-speed attacks and destroying buildings, notes YouTube and Anime Battle Arena (ABA) Wiki.
Regeneration: Can restore health by consuming blood.
