Say Hi to the BoB Brawler
Oga has been chosen to be the parent of Beelzebub, the son of the Great Demon Lord. However Oga's suffering since every time Baby Beel cries he lets out a severe electric shock. Plus, according to Baby Beel's demon maidservant Hildegarde (Hilda), if Baby Beel moves farther than 15 meters away from his human parent Oga, the electric shock will reach lethal levels. Oga shuffles to school with Baby Beel clinging to his back, having no other choice, and begins to search for someone even stronger than him that Baby Beel will take a liking to, in order to get this monkey off his back, literally!
