Sleepy Princess in the Demon Castle, Vol. 16

A captured princess just wants a good night’s sleep! Shhh…

Kidnapped by the Demon King and imprisoned in his castle, Princess Syalis is…bored.

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