Ultraseven: S1 E16 - The Eye That Shines In The Darkness Ultraseven
Sakura 9, the unmanned spaceship lauched as part of the investigation research project for Planet Annon, returned to Earth all of a sudden. The spaceship, however, soon exploded after landing. At somewhere close to the landing point, a young boy found a strange stone, and hears voices talking to him. The voice claims itself as a being from Annon, and the stone is the body needed for the beings to live on earth. From its words, seemingly they saw the launch of Sakura 9 as an attempt of invasion from Earth!
