Sleepy Princess in the Demon Castle, Vol. 18

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.When the Demon Castle collapses (unbelievably, not due to the actions of the usual suspect), its staff and "guest" go glamping in the surrounding environs. Rebuilding is taking too long, however, so Demon King Twilight resorts to drastic measures! Now everyone is afraid of him-except for one resident who still sees him as he truly is. Plus, the princess tries to unveil Fire Venom Dragon, grimoire Alazif finally finds someone to appreciate him, and the hero actually makes some progress!
