Seeking adventure during a school field trip, fifteen kids stumble upon a strange man in a cave, who invites them to play a game.
A strange creature named Koyemshi introduces itself to the group; Takashi is chosen as the next pilot of Zearth, and he resolves to protect the Earth.
Questions remain in the wake of Takashi's death; Kodama is selected to be the third pilot.
Masaru's family life has made him come to divide the world into two types of people: those born to die, and those born to survive.
The children realize just what it means to be chosen as a pilot for Zearth.
The next pilot is Kako, but the other kids can't find him, though Chizu has an idea of where he might be.
