Pero cuando un gatito es atacado, Åpodrá una desconocida enmascrada enfrentarse a los monstruos junto a ... La Princesa de Negra?"-- Princess Magnolia and Princess Sneezewort have plans ... mysterious plans, like a princess playdate! They dress-up slam! They karaoke jam! They playhouse romp and snack-time stomp! But then a shout from outside Princess Sneezewort's castle interrupts their fun. It's a monster trying to eat someone's kitty! This is a job for the Princess in Black. Yet when the Princess in Black gets there, she finds only a masked stranger and no monster in sight ... or is there? Back cover.

Translation of: The princess in black and the mysterious playdate.
