Chacha Kenomoto is a 15-year-old high school freshman burdened by an unusual ability: she communicates with cats, understanding and speaking their language. This skill constantly disrupts her attempts at an ordinary life. Her family name, "Kenomoto," meaning "Chatting with Creatures," inherently ties her identity to this power.

Her interactions with cats are chaotic and frustrating. Neighborhood strays bombard her with marriage proposals, intrusive offers of "help" like cheating on tests, and unwanted offerings like dead mice on her pillow. She views this ability as an annoying curse, exacerbated by the cats' crass, perverted, or nonsensical behavior.

Her best friend, Mito Azuma, admires the power, finding it enviable and cool, creating a stark contrast as she struggles to understand Chacha's resentment. Despite Mito's enthusiasm, Chacha remains overwhelmed by the relentless feline antics that follow her everywhere, shattering her routines. Her ability extends to big cats, though this aspect receives less focus.

Her documented experiences consistently revolve around comedic, repetitive scenarios that highlight the clash between her desire for a normal school life and the chaotic, unending interference from the cats.
