Berith (ベリス, Berisu), also known as Berito (ベリト) in the Devil Children series, is a demon in the series.
According to the writings in The Lesser Key of Solomon, Berith is the twenty-eighth spirit listed in the Goetia. He rides a gigantic red horse and burns those without manners. He is the duke of Hell. He is a Great Duke of Hell with twenty-six legions of demons under his command. He is depicted as a knight or soldier wearing red armour and a golden crown. In order to speak with him the conjurer must wear a silver ring and hold it before his face. He gives true answers to all things past, present and future as long as he is asked, but when not answering questions is a liar. He can turn any metal into gold, give dignities and confirm them.
Berith may be derived from Baal-berith, a god worshiped in Canaan before he came to be viewed as a demon under Christian demonology.
Berith appears alongside Ose when he acts as the final boss of Act 18. He also appears with all of the Fallen bosses as a mini-boss before the final encounter with Seth.

Devil Children Fire & Ice Book
Before the story began Berith was kidnapped and sealed away by the demons of Fire and Light from Muspelheim. The Fake one would later seal away the real Zebul. When Akira arrives at the Deep Hole, Berith will congratulate him before saying his journey will end here. After his defeat he would transform into his true demonic form and disappear, stating that the two will meet again in the world of Flame. Like the other Fake Brothers, the difference between the real one and fake one is the skin tone and face.
