Beelzebub (Firegod00)

Beelzebub (ベールゼバブ Bērezebabu) is the current Demon Lord of the Wind, procured from his former sealing in the Colstones by Rei Mokuzai, as well as being contracted to him for a significant period of time. A master of all of the air, Beelzebub is an opponent so mighty few would dare cross with him. He has provided a portion of his power to Rei, and appears to have come under his wing, if only for his own benefit.
