Beelzebub

As Kanzaki tries to come up with a new special move to beat Oga, his followers suggest the key to Oga's power is having Beelzebub on his back. Thus, Kanzaki starts training with a weighted baby doll on his back. When that plan doesn't work, they try finding a living substitute, which end in more embarrassing results. Meanwhile, Oga takes Beelzebub to the park where they once again meet Aoi, who has lost track of Kouta. Kanzaki coincidentally finds him and deems him a worthy substitute for Beelzebub. Whilst playing with him, he figures out the key to performing his new special move. After returning Kouta to Aoi, Kanzaki performs his special move, though it just leaves everyone confused. As Kanzaki leaves, Oga admits his move was surprising.
