Once upon a time, an idol named Taisuke had a teddy bear that he named Tiffany. He used this bear as a prop to gyrate against during his concerts, and she was well-received. However, the concert tour had to end one day, and so Tiffany was left without a job. So she decided to set out on a journey. She traveled through many lands, over hill and dale, across rivers and through woods, until finally she met another bear. This bear said he was in need of a partner, to star in a children's storybook with him, so Tiffany happily took up the job. The end.

ETA: The idol named Taisuke had to find another small, fuzzy animal to cuddle instead, so he went with the next best option, which was a fellow band member named Kitayama.
