It is explained how Genzo had turned into a dove, in that he also had previously entered the chamber. Seikichi is upset that Sora stayed out all night with Ginjiro, afraid she might be found out. Tetsuju chases Genzo into the row house, using a self-propelled fire boat, catching the eyes of the residents. It is revealed that Tenho and Tenten are lurking inside Ginjiro's room. Akai spies on Ginjiro, who takes Tenho and Tenten with him to see Toyama. Ginjiro tells Toyama that he is working for Torii at his own will, not due by force. Meanwhile, as Seikichi tests out his own fire boat, a selfish Tetsuju challenges him to a race. When an angry Oriku soon joins them, she blows up the fire boat, causing Seikichi to drown. Sora then reluctantly dives in to save him.
