This diorama clock places Madara, better known as Nyanko-sensei, at the center of a cozy, study-like scene. The figure captures Nyanko-sensei's chubby, cat-like form with a round face, small whiskers, and bold stripes, perched atop a decorative clock base. He holds an open book in one paw, eyes gleaming with mischief and curiosity, as if pausing from guarding the Book of Friends to observe the moment. The clock face is integrated into a carved wooden frame, surrounded by delicate foliage, talismans, and a scroll motif that nods to the series' yokai folklore. Subtle shading emphasizes fur texture and the contrasting colors of browns, creams, and gold trim. The voice feature adds a playful touch, suggesting Nyanko-sensei's signature lines when the clock chimes. Overall, the piece blends whimsy, lore, and a quiet scholarly mood.

In Natsume Yuujinchou, Nyanko-sensei begins as a powerful youkai who appears as a skeptical chubby cat and becomes a reluctant guardian to Takashi Natsume, a human boy who can see spirits. The two form an unusual partnership as they travel through town and countryside, encountering friendly and dangerous spirits, seeking to return or guard the names bound in the Book of Friends. Nyanko-sensei's playful attitude hides a deep loyalty and practical wisdom; his appetite for food and boastful bravado contrast with the gentle, haunted world Natsume navigates. This figure, named Madara, captures the moment of kinship when Nyanko-sensei agrees to accompany Natsume on his quest to free spirits from binding names. The clock motif mirrors the recurring theme of time, memory, and the delicate balance between human and youkai lives in the series.
