The Cat of Nabeshima is a horrible vampire demon from Japan that took the shape of a cat, murdering a courtesan and then focusing its furry evil on the prince of Hizen, a member of the Nabeshima family.
This bad kitty took down the concubine (aka mistress) O Toyo and then transformed itself to look like her. In this form, the vampire then spent every night with the prince, putting a spell on him and draining him bit by bit. The prince grew more ill with each passing day and his doctors were unable to find a medicine that would help him, however, they did notice that he got worse at night (hmm wonder why). Guards were then posted to keep watch at night but they kept falling asleep. Turns out our catty vampire was putting a sleep spell on them. The dying prince noticed a lowly soldier named Ito Soda praying for him, the soldier then begged the prince to let him stand guard. When the magic sleeping spell fell upon Ito Soda, he stabbed his thigh to keep himself awake and he saw a lovely young woman enter the prince’s chamber.
Soda’s presence worked against the vampire’s spells and she was unable to feed from the prince. She tried to make Soda fall asleep but failed, so she was forced to flee. Shortly after she left, the prince began to recover. Clever Soda was convinced that O Toyo was a vampire and he went to her apartment, gaining entry by saying he had a message. As he got close to the vamp, he lunged with a dagger but she flew across the room, grabbed a weapon and attacked him. Lucky for Soda this vampire failed at fighting. When she finally realized she wasn’t going to win she turned into a cat, jumped to the roof and escaped into the mountains. The poor locals were terrified until the prince led a great hunt to find her. The vampire cat was found and killed, yet the people of Nabeshima continue to fear the beast -which was last reported seen in 1929.
