Ban heads to Purgatory and finally reunites with Meliodas. The next thing they should think about when they met their best friend and were in tears was how to escape from this purgatory. They expect that the key is held by her father, the Demon King, who locked Meliodas in purgatory. A familiar creature appears in front of the two who try to change the situation by groping while preparing themselves. It was a hawk and two "wild" melons.
