Musashi and Hanabi are working to replace the old machines when a giant bear appears before them! The bear comes with a girl who emits universal waves. Who is she? And why is she friends with a bear?

Worried about Musashi's workaholic habits, the girls force him to take a day off. But the measures they employ to drum up business in his absence have unforeseen consequences...
