Sleepy Princess in the Demon Castle, Vol. 26

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.

Twilight, Zeus, and the princess must prepare to face a truly harrowing challenge—attending incognito at the Goodreste Royal Academy! However, things quickly go awry when they encounter a group of demon-obsessed students, a mysterious grimoire, and the most dangerous enemy they’ve ever faced. Then Demon Cleric deals with some non-Syalis feels, Odile’s vacation fail ends with him getting eaten by a whale, a princess possessed by a father proves a bother, and more!
