Diane and King, not knowing of Meliodas' revival, mourn over his death together. As the Giant and Fairy Clans now live together in the Fairy King's Forest, King has created a barrier to repel demons and the peace culminates in a dance festival. During the dance, Gerheade sees a vision of the first Fairy King, Gloxinia, who is grateful that she is alive. When the dance stops however, everyone realises that Diane and King are missing, the two having been teleported to Drole and Gloxinia. The two former kings promise to kill them unless they successfully pass a test after completely defeating them. Drole and Gloxinia transport Diane and King into their past selves respectively, in order to help them determine whether they made the right choice 3000 years ago and wound up being members of the Ten Commandments. Diane and King watch through Drole and Gloxinia's eyes as they fight alongside Meliodas and a member of the Goddess clan greatly resembling Elizabeth against the Demon Clan.
