Sonico goes on a trip for some lyrical inspiration, conversing with another woman on the way to her stopover in Niigata. Whilst stopping over in Tainai City, Sonico comes across a glassmaker, who teaches her to make a little accessory. The next day, Sonico heads towards the local hot springs, meeting people and encountering many sights along the way. After checking into the hot springs and taking a dip, she tries to find her way to an observatory but gets lost in the woods. However, she manages to follow a raccoon to where the observatory is, becoming awed by the starlit sky.
