Demon King Twilight's childhood friend Zetsuran sneaks into the castle determined to be reunited with him, but the princess keeps getting in her way. Hades wants to reconcile with his little brother Zeus, and naturally the princess gets mixed up in their business too. Meanwhile, Alazif the grimoire gets a form of hay fever that has unfortunate magical symptoms. If stepping on a butterfly in a primeval forest can drastically change the future, what impact would a princess stealing an ancient duvet ten years in the past have? Plus the princess goes on a fishing trip with the Demon King and Poseidon. What could possibly go right?
