Berith

"'When he opened the second seal, I heard the second living creature say, “Come!”undefinedAnd out came another horse, bright red. Its rider was permitted to take peace from the earth, so that people should slay one another, and he was given a great sword.'""- Revelation 6:3-4"Berith is the Greater Daemon who leads the Legion of War, and is best known as the second Horseman of the Apocalypse. He most commonly appears in mortal form riding a red horse. His role when the seals are broken is to incite chaos and discord, creating endless conflict.

In Walker Sequence it is revealed he is the Daemon that sired Dante Cross.

Relating to Clara Everis
Walker Sequence also explains that Clara Everis, while an Exorcist working for the Gold Sacrament, disputed the claims that they must eradicate all Demons to attain peace. She reached out and made contact with a Greater Daemon to better try and understand them. It was, rather ironically, Berith who answered her call. Despite the nature of his origins, they had an effect on each other.
