I Stopped Being a Gang Leader with a Child

is episode 18 of the Beelzebub anime.

Summary
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.

Next episode preview
Furuichi cheerfully concludes the story claiming Beelzebub's new father is now Tōjō of the Tōhōshinki, and speaks to Oga. Oga, however, is still unsatisfied at the outcome of his fight with Tōjō and still wants to beat him. Arandron mentions a way for him to get Beelzebub back, although potentially fatal. Oga is fine with it anyways. After Arandron introduces the next episode, Furuichi wonders if the doctor coming in will also have a pretty nurse. Arandron merely snickers.
