Intro. Yatsuki and Yuchira are two plushies that were originally going to be "just toys," but somehow they are alive and going around biting people and making a type of gooey pink/white substance, that when a human steps on it, the human transforms into a shorter chibi version of themselves with a large cat tail and ears. If they were to encounter a child, they wouldn't infect them due to the girls thinking they're already cute. They can make the gooey substance into smoke, which makes it easier
