However, his poor health that had continued since the apex meeting was affecting his daily life. Before the final battle, Emi, who couldn't bear to see the Demon King, worried about him...? What is the truth of the heavenly world that awaits the Demon Kings who cannot dress up to the end? Will they succeed in defeating the Gods?
