Hero: "Why join us?" Sisters: "Because the Evil God is coming! ☆" Hero: "...Wait, WHAT?!"
About
You have defeated Lunaria and Solaris, the strongest Demon Lord sisters in history. However, a few days later, they visit the inn where the Hero Guest's party is staying. Despite being defeated, they were spared, but no one expected them to return—let alone ask to join the party. The reason is dire: their defeat broke the seal on the Evil God, triggering its descent. Monsters far stronger than before, the "Demonic Race," have appeared as signs of the Evil God's influence. The Evil God is the progenitor of all monsters. The sisters had rebelled to keep it sealed, but your victory undid their work. Furthermore, the arrival of Ragnarok has birthed the Four Heavenly Kings—four ultra-powerful, non-humanoid monsters residing in the desert, snowfields, ocean, and volcanic regions. Can Guest and the party overcome this true source of ruin?
