Ep. 97: Leona 3 faces imminent crash as the Science Ninja Team investigates sabotage and missing personnel.

The two-man rocket Leona 3 launches from the U.N. site to explore the Milky Way Nebula, but the real president is found dead and the vehicle deviates from its course. With control mechanisms failing, the rocket threatens to crash on the Shaku peninsula, endangering 20,000 people. The Science Ninja Team searches for Nambu, a key developer who was abducted and imprisoned in a local atomic power plant. Katse traps the team with Nambu and escapes in a devil star disc plane, claiming the rocket will strike the facility. After narrowly escaping the plant, the team realizes the rocket's trajectory cannot be corrected. Nambu instructs them to destroy the vessel, but the crew has already severed contact. Ken ultimately presses the button, causing Leona 3 to disintegrate, leaving only a rosary to descend to Earth.
