Description
Cielo is a central figure in the anime film The Obsessed, serving as the deuteragonist and the narrator of the story. He is the pet mouse and best friend of the protagonist, Giuseppe. His role is essential to both the structure and the heart of the narrative, as the entire plot is presented from his unique perspective.

Regarding his background, Cielo is not just an ordinary animal. He is a talking mouse who possesses human-level intelligence and language abilities. The story shows that Giuseppe found Cielo and raised him from infancy, an act of care that led Giuseppe to learn the mouse language to communicate with him. This relationship is a product of one of Giuseppe's many intense but temporary fixations, yet it results in a lasting and profound bond.

In terms of personality, while detailed descriptions are limited to the narrative function he serves, Cielo is portrayed as a witty and observant character. As the narrator, his voice provides a degree of levity and charm, framing the often chaotic life of his owner, Giuseppe, within a light-hearted and sometimes comedic context. His perspective helps the audience understand that Giuseppe's obsessive behavior is not cruel or malicious but more like an uncontrollable sickness. The character is described as bringing a necessary "manic energy" to the film, contrasting with Giuseppe's more still and centered nature.

Cielo's primary motivation is rooted in his deep loyalty to Giuseppe. He acts as a confidant and an advisor, observing his friend's life and romantic pursuits. When Giuseppe becomes obsessed with a young immigrant balloon seller named Pechka, Cielo aids him in his quest to win her heart and solve her problems. His role is not to take direct action in the romance but to witness, comment on, and assist Giuseppe by helping him apply the various skills he acquired from his past obsessions, such as singing, embroidery, and private investigation.

The key relationship of Cielo is exclusively with Giuseppe. There is no information suggesting significant relationships with other characters such as Pechka or the gangster Mr. Twist. His entire existence in the narrative is tied to his human companion, whom he has known since his own infancy. Their friendship is the cornerstone of the story's emotional core, providing a stable, loving relationship that contrasts with Giuseppe's mercurial passions.

Regarding his role in the story's development, Cielo functions as the constant through Giuseppe's changing obsessions. While Giuseppe's character arc involves learning to turn his fixation on a person into a sustained and selfless love, Cielo remains a static yet reliable presence—the unconditional friend and the calm observer who chronicles the events from beginning to end. His narration guides the audience through the plot, from the comedic first act to the more emotionally and ethically complex later stages of Giuseppe's journey.

Cielo possesses several notable abilities. Most prominently, he is a talking mouse, capable of fluent speech in what is presumably human language, as he serves as the film's narrator. He is also described as a multilingual mouse, indicating a proficiency in more than one language, which likely includes the language of mice that Giuseppe learned. In addition to his linguistic skills, Cielo is also a singing character, with promotional clips for the film highlighting him performing an in-movie song titled Snowish.
