Future Devil

"The future! Rules!"

The Future Devil (未来の悪魔) is a devil that embodies the fear of the future. After seeing Aki Hayakawa's future, it made a contract with him, so he can see that future himself.

Appearance
The Future Devil's lower half resembles a tree growing from the floor with branches and a trunk extending up to a humanoid body with outstretched arms and a horned head. Multiple vine-like streamers grows from its arms and chest.

Its face has three pairs of eyes stacked on top of each other vertically and its wide mouth is almost perpetually open.

The Future Devil has a large hole in the center of its chest, inside of which is another oversized eye.

Personality
It has a extremely playful personality and regularly boasts that the future is best.

History
At some point the Future Devil was captured alive by Public Safety and locked up. It went on to make contracts with two Public Safety Devil Hunters, with one of them giving up half their lifespan and the other giving up both eyes, their sense of taste and their sense of smell.

Katana Man arc
Kurose and Tendo lead Aki Hayakawa to a place where devils are locked up by public safety in order to find him a new weapon. They lead him to the Future Devil and tell him to make a contract with it. Aki enters the Future Devil's room and sees its full appearance as it announces repeatedly that the "future rules".

Aki and the Future Devil talk, and the Future Devil disapproves of his attitude. It orders Aki to stick his head in its belly so that it can see his future and uses that to determine the details of their contract. After laughing at Aki's future, the Future Devil makes the offer that so long as it can live in Aki's right eye, it will help him. It reveals that the reason for why this contract is cheap is because it wishes to see Aki's future with its own eyes and that Aki is fated to die in "the worst way possible".
