The mysterious beauty who suddenly appeared before Canaan and the others was Jeanne, refreshed after taking a bath and having her impurities (flabby flesh) washed away.
Jeanne was accused of stealing Canaan's underwear and was about to be publicly executed.
However, Jeanne had no recollection of doing so and was completely innocent.
Canaan had a hunch about the culprit. It was her younger sister, Mirch, a bratty girl who had been stealing Canaan's things since they were kids.

Finally, the stamps for Lilim, Mirch, and Miel are all collected, leaving only Beelzebub.
The final trial that Beelzebub has imposed on them to get his stamp is—a beach volleyball match!
Canaan and Gogyo-kun take on the Zebul family beach volleyball challenge.
Will the two be able to overcome this trial of love?!
The love story between the adorable demon and the inferior being (human) is finally reaching its climax!!
