Aki Hayakawa is a character in the best selling-manga (and now anime series) Chainsaw Man. The series takes place in a world where devils are born from fears. Aki works for Makima as a public safety devil hunter. However, he takes his responsibilities more seriously than Denji. While he comes off as stoic, he deeply cares for his peers. He has a contract with the Fox Devil and Curse Devil which allows him to summon their abilities. His later contract with the Future Devil gives him a glimpse into a horrible future, which results in a fatal fight.
