Sleepy Princess in the Demon Castle, Vol. 20

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.

A secretly filmed video of life at the Demon Castle embarrasses its occupants. Agave finally confronts her demons—or rather, the Demon King. Then, when Princess Syalis messes with a magical spinning wheel, it’s Poseidon who takes the hit. To rescue the god of the sea, the princess must embark on a deep dive into the history of the spell and…her own family?! Plus, Twilight’s first love revealed! Sort of.
