In a quiet countryside village, Rin, who works at a bakery, seemed like an ordinary human girl… but in fact, she was a cat beastkin. Every day, she hid her ears, tail, and claws with effort— But this morning, she accidentally served bread to a customer with her claws out. “Wh-what… cat paws?!” As the customer froze in shock, the bakery owner appeared with a lump of dough and added, “That’s… a magical mirage! A very rare magical reaction!” Rin smiled, but inside, she was sweating nervously. ‘At this rate, my secret’s really going to be exposed…!’ But Rin’s wish to live quietly while hiding her identity didn’t last long. One day, a knight with black wolf ears, Sir Roen, came from the royal palace to find Rin and said, “You, who carry the bloodline of the beastkin—please become the royal librarian.” “Um… I’d rather just bake bread?” And just like that, Rin’s quiet country life came to an end. Now constantly worried about revealing her ears and tail, she had to survive a new daily life in the royal palace—where ancient books and swords flew instead of flour and pastries.
