Nora, Princess, and Stray Cat

Nora Handa is an ordinary high school boy until he meets a mysterious girl named Patricia in the park. She insists she's a princess from the underworld, and after an accidental kiss, Nora suddenly transforms into a black cat. Patricia brings him to her home, where he eventually turns human again-but the change doesn't last. Now, Nora keeps shifting unpredictably between human and feline forms, leaving him caught between two worlds.
