The episode begins with Zairin, still testing the Bio Volcano, where he is informed of Ruuji's last known movements. He moves to inform Jiin, but is reminded that an imperial meeting is underway in the capital. At the meeting, Jiin talks with his father, who takes him, along with two other officials, to the topmost point of Digu's tower. Here, they are met by three people, who, in exchange for Reggel, give them schematics for a new wireless communication device, before vanishing in a flash of light. On the way back down, they mention who it was they were dealing with, the Sky People.
