I don't remember ever having a human!

A struggling novelist, Matabi, picks up an injured and weakened cat one rainy day. However, the true identity of the cat is a 1,200-year-old nekomata who can transform into a human! Manipulating people's words, her human appearance is a perfect beautiful girl! She says her name is Kaneko (short for cute cat). Sanadao, who has run out of material for novels, has faint hopes that he may be able to gather material, but the days of being swayed by a senior senior in human (?) life begin!
