Chizuru Mochizuki is a supporting character introduced in the third episode of the anime. She is a college student who works part-time as a mail carrier, a job she performs while wearing her distinctive delivery uniform. Her most defining external trait is her complete lack of a sense of direction, which frequently gets her lost while trying to make her rounds. Physically, she is an adult female with brown shoulder-length hair and yellow eyes.

In terms of personality, Chizuru comes across as cheerful and somewhat easygoing, but she also possesses a teasing and mischievous side. She tends to act as a temptress, enjoying the discomfort of others in lighthearted situations. Some observations of her behavior suggest she holds a secret, somewhat perverted curiosity about romantic or embarrassing scenarios. This playful nature often leads her to create or exacerbate awkward misunderstandings, much to the despair of the protagonist, Junpei Kousaka.

Her role in the story is primarily that of a catalyst for comedic situations. When Junpei encounters her while trying to complete his cursed obligations to help cats, he decides to assist her with her deliveries. This decision puts him in a series of compromising positions that are witnessed by other female characters, generating classic romantic comedy misunderstandings. Her function in the narrative is less about advancing a personal goal and more about creating chaotic, humorous scenarios for the main cast.

Her key relationships are primarily defined by her initial meeting with Junpei. She serves as a temporary companion for him during an episode, and their time spent walking together around town is the source of numerous comedic errors. The protective or jealous reactions from Junpei's other love interests, such as Kaede Mizuno and Kanako Sumiyoshi, are often triggered by seeing him in Chizuru's company. She does not share a significant relationship with any of the cats, as her interactions are almost exclusively with the human characters.

Regarding character development, there is no reliable direct information available. She appears as a situational character whose traits remain consistent throughout her appearances, serving a specific comedic purpose without undergoing a significant personal arc.

Concerning notable abilities, there is no reliable direct information available. Her lacking sense of direction is a notable flaw, but she does not possess any supernatural or exceptional skills within the context of the story.
