Who Is the Future Devil in Chainsaw Man? Explained

To start, it’s worth digging into who and what the Future Devil is in Chainsaw Man. Representing humanity’s fear of the future, the Future Devil is one of the stronger Devils in the Chainsaw Man universe. It can see as far into the future as it wishes, and can view the future of specific individuals by having them stick their heads into the hole in its stomach. It can make contracts with people through the usual means used by other Devils, and due to its high level of power, it typically asks for a decent amount from those that try to bargain with it. However, it’s worth noting that the Future Devil isn’t as kind as the Fox Devil or others that don’t mind humans. It enjoys watching humans suffer, and typically makes contracts with those it knows will provide it with a spectacle when they die. It basically lives by the saying “Man plans and god laughs,” reveling in its ability to watch as inescapable futures play out for unsuspecting people.

Why Does the Future Devil Make a Contract With Aki?

This is a big reason as to why the Future Devil makes a contract with Aki in Chainsaw Man. After Aki sticks his head into its stomach, it begins to laugh maniacally. It then reveals that Aki will die in the worst possible way, and that all it asks for in exchange for making a contract is to be able to live in Aki’s right eye. This would allow it to see Aki’s death play out directly, and to enjoy the hardship and pain caused by said death up-close. In exchange though, Aki gains a pretty substantial power-up. He is granted the ability to see into his own future by a few seconds, allowing him to dodge any attack and ensure any attack he lets off lands without fail. This helps him greatly in his eventual rematch with Akane and Katana Man, ensuring he isn’t hit by Katana Man’s lightning-fast attacks while also helping him to anticipate the different moves Akane tries to hit him with. Hopefully this cleared up who the Future Devil is in Chainsaw Man.
