Psycho Jenny

Psycho Jenny is one of the leading figures in Satan's demon army alongside Zennon in Devilman series. She has displayed incomparable psychic abilities, including manipulation of time and implanting fake memories into others. She is the only person other than God and his highest command of angels to have awareness of the time loop that she and her master are forever trapped in.

Psycho Jenny carries an air of mystery. She very rarely speaks unless spoken to (and even then only telepathically), often just staring blankly. Unlike most demons, she doesn't appear to have any emotional investment in either the destruction of humanity or the war against God, and is only loyal to her master Satan. Although she seems to find Satan's love for Akira Fudo slightly foolish.
