Ginjiro advises Seikichi to travel alone with Sora to test out more fireworks, but also to settle their differences. There they meet Tetsuju the Human Fuse, who views Sora as Princess Moonbeam, much to Seikichi's chagrin. The myth behind Princess Moonbeam is explained.

After stumbling upon Tetsuju's cabin of firework cannons, Seikichi realizes how determined he must be to build a firework cannon, all when Tetsuju launches his own into the sky.
