Sleepy princess in the Demon Castle / Kumanomata, Kagiji

"When Teddy Demon gets into a kerfuffle with Eggplant Seal, the cuteness is un-bear-able. But then Teddy Demon gets lost and is rescued by. . . the hero Dawner's inept rescue party?! Meanwhile, Quilladillo's fitness regimen doesn't come without its drawbacks. . . for the princess. Plus, brothers Poseidon and Hades bond over a common weakness, Midnight finds a new prime suspect to blame for shrinking him, and Great Red Siberian sheds!"--Back cover.

"When things seem too peaceful in the Demon Castle, the demons investigate and find the princess in a literal bind. Having stolen a gizmo to create alternate dimensions, Princess Syalis uses it to do good in the world. Just kidding! Of course she uses it for her own (and the Teddy Demons') selfish gain. Then, a lightning storm reveals one demon is (predictably) even more frightened of thunder than the princess. Quilladillo goes home for vacation only to discover he has a stowaway in his trunk, but it's not the princess. Just kidding! Of course it is. And then a relative of the princess appears at the castle! What are the demon hostage takers to do...?!"--Back cover.

"Kidnapped by the Demon King and imprisoned in his castle,Princess Syalis is--bored. Celebrate New Year's, Valentine's Day and a very special pajama party at the Demon Castle with the princess and her demon friends--er, captors! Then the Five-ring-pics athletic tournament captures the imagination of demons and human alike. But when one of the athletes turns the demons' human friend--er, hostage--into a besotted fangirl, the castle staff doesn't take it well. Also, Syalis imbibes a potion that induces her greatest fear, Demon King Twilight desperately tries to change his image and the hero Dawner adds a certain someone to his unwelcome rescue party"--Back cover.

"Princess Syalis manages to mess up Christmas and Valentine'sDay . . . again. Then, when Syalis and her demon captors pay a visit to her kingdom of Goodereste, a demon stands in for the princess . . . and winds up needing to be kidnapped herself! A common enemy forces Syalis and her archnemesis Poseidon to team up. And Syalis messes up more things, including a DemonCastle hot-pot party and a Demon King educational biopic. But she still manages to find some good opportunities for relaxing naps . . ."--Back cover.
