One of the Seven Satans, "Wrath," she is Lucifer's first wife and the mother of many demons and Abbadon. Barubelo was once an angel in Heaven named Baru. She watched over Lucifer (Lucifel) and Michael when Lucifer still resided in Heaven. During the First Great War, she compelled Michael to take her to the battlefield so she could witness the fight for herself and confirm that Lucifer was indeed leading the army. When Michael went to attack Lucifer, she intervened and was struck down by Michael's sword. After the battle, Lucifer saved her life and made her the Satan of Wrath.
However, she retains memories of her life as an angel, along with a scar where Michael had injured her. Initially, Michael did not know that she had survived his blow. But as Lucifer began dropping hints, Michael eventually realized who she was. He then struck her down a second time, as she was holding onto Setsuna's leg to prevent him from escaping.
