Biography
Baal is one of the short-tempered members of an elite group of demons called the Thirteen Crowns who possesses electrokinetic abilities. Baal longs to return the netherworld to its time of savagery. Sometime before the events of the series, Baal met Ami Kirio, a sadomasochistic demon boy who got off on despair. He allowed him to join his Battora (Battler) party, Magical Tools Research, and gave him the knowledge to create a magical device to destroy Babyls (Babirus Demon School). The two conspire for a good few years until the present day where Iruma Suzuki became a student of the demon school.

They both agree on the plan to detonate an explosion during the Battora event where Amy would use his barrier ability to trap a chunk of the students inside the school where they would be killed in the explosion. Their families would despair over their losses and revert back to their primal states while additionally ending the power rankings in the netherworld. Baal would often converse with him under the guise of his guardian. He was also the mastermind behind getting Sullivan arrested as a means of keeping him gone long enough to enact the plan.

Unfortunately for the two conspirators, their plan is foiled when Amy fails to make Iruma fall into despair and uses up a large portion of the magic within his ring to destroy Amy's barrier. Amy is then arrested for the terrorism scheme but claims ownership over it.
