The 999 arrives on a planet where everyone is very beautiful, but also extremely weak, not even going outside during the day due to the sun. A couple steals a suitcase containing Tetsuro and Maetel's passes, but they pass out from running and when they shoot Tetsuro, it is too weak to harm them. They still manage to switch Tetsuro and Maetel's passes with fake ones though, and board the 999.
