Ceramicist Meyer is a character from the anime adaptation of the children's novel Manxmouse. He is a craftsman living in the fictional English city of Buntingdowndale whose specialty is creating ceramic replicas of mice. His most significant act occurs on the night of his creation of the title character, an event that sets the entire story in motion. After attending a party where he becomes intoxicated, Meyer returns home with the ambition of crafting the finest mouse figurine he has ever made. However, with his senses and judgment impaired by alcohol, the resulting statue is a bizarre and fantastical creature rather than a realistic mouse. The figure possesses a fat body like an opossum, hind feet like a kangaroo, the front paws of a monkey, and long ears resembling those of a rabbit, which are blue and vividly orange on the inside. What the ceramist finds most troubling is that his creation has no tail at all.

Upon seeing his work in the light of day, Meyer is initially disappointed and considers the statue a failed experiment. Yet, upon further examination, he finds the little creature has an unexpectedly endearing quality. Noticing the stump where a tail should be, he is reminded of the tailless cats from the Isle of Man and decides to name his creation a Manx Mouse, deciding to keep it rather than destroy it. Unbeknownst to him, that very night while he sleeps, the ceramic statue magically comes to life. The newly animated being, who calls himself Manxmouse, then leaves the ceramist's home to begin a journey of adventure and self-discovery.

Meyer’s role in the narrative is that of an unwitting creator and the origin point for the protagonist. His drunken state of lowered inhibition is portrayed not as a simple mistake but as a necessary condition that allowed him to break free from his conventional work and produce something truly unique and magical. The contrast between his professional ambition to make a perfect, standard mouse and the extraordinary, fearless creature he actually makes highlights themes of unintended consequence and the unpredictable nature of art. While his own personality is not explored in depth beyond this creative episode, his action of sparing the flawed statue out of fondness demonstrates a sentimental and open-minded side to his character. As a ceramicist, his notable ability is his skilled craftsmanship in molding and firing clay, a talent which, when combined with an unusual night of inspiration, results in the birth of a living being.
