Movie
Description
Muta, also known by his formal name Renaldo Moon, is a large white cat who first appeared in the animated film Whisper of the Heart before taking a more prominent supporting role in The Cat Returns. His background includes a notorious past in the Cat Kingdom: years ago he devoured an entire lake of fish in a single sitting, gaining a reputation as a criminal in that realm. Despite this history, he spends most of his time in the human world, often near a crossroads, where he is encountered by the protagonist Haru.

Personality-wise, Muta is brash, grumpy, and openly sarcastic. He has a sharp, cynical tongue and frequently expresses condescension toward others, including his companions. His immense appetite is a defining trait, and he is highly sensitive about his weight, becoming irritated when anyone compares him to a pig (the Japanese word "buta" is used against him). Beneath his gruff exterior, however, he possesses a strong, if reluctantly expressed, sense of loyalty and protectiveness. His motivations are primarily driven by a desire to ensure Haru's safety after she becomes entangled with the Cat Kingdom, and he grudgingly takes on the role of a reluctant mentor.

In the story, Muta serves as Haru's initial guide: a mysterious voice directs her to find him, and he leads her to the Cat Bureau, where she meets Baron Humbert von Gikkingen. When Haru is forcibly taken to the Cat Kingdom, Muta accompanies her under duress. Throughout the adventure he provides practical, street-smart advice and uses his size and experience to intimidate adversaries. He also reveals his true identity as Renaldo Moon at a crucial moment, which helps shift the dynamics of the Cat Kingdom's politics. His role evolves from a grumpy bystander to an active ally in Haru's escape.

Muta's key relationships include his bond with Haru, whom he initially finds exasperating but grows to respect, especially when she stands up for herself. He shares a deep but often argumentative friendship with Baron, whose refined composure contrasts with Muta's bluntness. He also has a mutual dislike with Toto, a stone crow who becomes a living ally; the two constantly bicker. Muta's connection to Yuki, the white cat maiden, is indirect but significant, as Yuki was the one who guided Haru to seek him out.

Over the course of the film, Muta undergoes noticeable development. He begins as a cynical observer who complains about being dragged into Haru's troubles, but he gradually becomes a committed protector, willing to risk himself for her sake. His final words to Haru after she rejects the Cat King's proposal reflect his newfound respect for her courage. This growth underscores his transition from a self-centered, sarcastic creature to a dependable friend.

Notable abilities include his practical intelligence and street savvy, which help him navigate tricky situations and outwit opponents. He is not magical like Baron or Toto; instead, his strength lies in his experience, his imposing physical presence, and his ability to act decisively when needed. His sheer appetite and blunt demeanor also serve as unexpected assets in the chaotic world of the Cat Kingdom.
