A pink-eared, pink-tailed cat girl named Moko awakens in a strange, picturesque town with no memory of anything except her own name. A note left beside her bed directs her to a café called Katze, run by a woman named Machia. There she learns that the town is Meltier, a hidden village inhabited by cat‑eared people like herself. Machia offers Moko a live‑in job helping to care for the café’s resident kittens, but gives her one firm rule: she must never leave Meltier.

Settling into her new life, Moko gradually meets the town’s other residents, including lively and kind friends her own age. She discovers that Meltier is suffused with a gentle magic, and she begins learning to use it. Early on, she finds a frightened, injured kitten in the forest, and her empathy for the lost creature mirrors her own loneliness, forging a deep bond. A series of small but ominous incidents—a black, shadowy substance appearing in the forest, a close friend becoming possessed by that same darkness—pushes Moko to train harder with her magic. Her growing power seems linked both to the town’s hidden history and to the gaps in her own past.

As the story unfolds, Moko’s desire to understand Meltier’s secrets leads her to uncover fragments of her friends’ histories and, ultimately, a startling truth about her own cat ears and the nature of the town itself. The narrative balances cozy, everyday moments in the café with an underlying mystery that slowly deepens, weaving a heartwarming fairy‑tale fantasy about finding a home and belonging in a place that holds more wonders—and more dangers—than it first appears.
