It's an intriguing question that has likely brought many JoJo's Bizarre Adventure fans here, eager to connect the dots between two wildly popular anime and manga universes. However, let's clear up a common misconception right from the start: Aki Hayakawa is not a character in JoJo's Bizarre Adventure. Aki Hayakawa is a prominent and beloved character from Tatsuki Fujimoto's dark fantasy series, Chainsaw Man.
While both series feature incredible powers, unique character designs, and intense battles, their worlds are distinct. This article will first clarify Aki Hayakawa's actual background and age within his own universe, then seamlessly transition into exploring the fascinating world of JoJo's Bizarre Adventure and its many iconic protagonists, whose ages, strengths, and stories form the bedrock of Hirohiko Araki's masterful saga.
Unpacking Aki Hayakawa's True Age and Origin (Chainsaw Man)
If you're asking about Aki Hayakawa's age, you're undoubtedly thinking of the dedicated Public Safety Devil Hunter from Chainsaw Man. Aki serves in Special Division 4, working closely with Denji and Power, acting as a stoic guardian and watchful presence. His primary drive for joining the Devil Hunters stems from a deep-seated desire for vengeance against the terrifying Gun Devil, which tragically claimed his entire family – his parents and younger brother Taiyo.
While his exact birthdate isn't explicitly stated, the manga does confirm a key detail about his age: Aki is three years older than Denji. Given Denji's initial age in the series is around 16, this places Aki Hayakawa's age around 19 years old at the start of Chainsaw Man.
