Erina loves cats more than anything, even though she looks like the haughty-princess type who could have any guy she wants. But even with a cat-like name, she can’t stand her aloof classmate, Nekoyama-kun. But when she rescues a hurt kitty in her yard and gives it a perfect, snuggly kiss…she suddenly finds a very human Nekoyama-kun in her room? What gives?!
Nekoyama-kun can turn into a cat by kissing any living animal. Since his classmate, Erina, found out about this, he moved into her house as her pet cat in order to keep an eye on her! However, he still has some feline traits even when he’s in human form. He would go bonkers when exposed to silver vine, get jealous of other cats, and make Erina follow his every whim…!!
