Beelzebub

Beelzebub gets a summer cold, causing his body to give off incredible heat. As his condition gets worse, the Zebel Spell on Oga's hand disappears, leading Hilda to become frustrated towards Oga for showing little care towards him. As Oga tries to decide what to do, he encounters one of Tojo's henchmen, Shojo Aizawa, who seemingly outmatches Oga before leaving. The next morning, both Hilda and Beelzebub have disappeared. As Oga searches for them, he encounters Tojo with Beelzebub on his back, who challenges Oga to a fight. As the two fight, Oga is shocked to see what appears to be the Zebel Spell on Tojo's shoulder, before he is knocked clean into the river.
