Sleepy Princess In Demon Castle Gn Vol 20

A leaked video from the Demon Castle embarrasses most of 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 from the effects of the wheel, she must embark on a deep dive into the history of the spell and...her own family?! Plus, Twilight's first love revealed! Sort of.
