Shinichi

"Did the soul of the boy whom died two years ago works as a messenger for the Nonmalts? No one will be able to provide an answer to the eternal mystery whether the Nonmalts were the original inhabitants of this planet now that all has been lost."

- The narrator's final words in the episode.

Shinichi (真市) was a boy that appeared in Ultraseven.

Ultraseven
One day while Dan and Anne were taking a day off, Shinichi went to Anne and asked her for the TDF workers on the Sea Horse and the undersea base to move away from the sea. She disbelief with what he said, as Shinichi went away. He also called the TDF Undersea Base and gave the same order while warned them of the consequences that brought by Nonmalt but to no avail. The ship and undersea base exploded instantly in front of Dan and Anne's eyes. While Dan and Anne went out investigating again, Shinichi appeared in front of them and told the same thing. Anne realised that the boy's way of talking was no difference compared to most alien invaders she met before. Shinichi was chased by TDF soldiers and squeezed by them but a Nonmalt saved him. Before Dan was about to transform into Ultraseven, Shinichi warned him multiple times of the consequences he would get but Dan transformed and battled Guyros while the Ultra Garrison destroyed the Nonmalt city with a barrage of torpedo.

Aftermath, while the Ultra Garrison were enjoying their victory, Shinichi approached to them and gave the last warning that Nonmalts would have their revenge in the future. Dan and Anne chased him but instead, they found a shocking truth: Shinichi had died two years prior. His mother buried him at the the same beach due to his passion for the sea.
