Snake Devil

The Snake Devil's personality is currently unknown.

The Snake Devil has the appearance of an enormous snake with a large mouth made out of interlocking arms and hands instead of teeth. It has green scales/skin and a red eye with black sclera.

As a Devil, the Snake Devil possesses all of the standard devil abilities, such the ability to make contracts with humans for a price. The only known contract is the one with Akane Sawatari. Sawatari is able to fully summon the Snake Devil and use its abilities through voice commands and hand movements, in exchange for sacrificing a fingernail for each command. To use the Snake Devil's abilities, Sawatari requires hand movements, so when her hands are held together, she cannot use them.
