The Terrestrial Defense Force establishes the Ultra Garrison, a team of six elite members who utilize high-tech vehicles and weaponry. Joining their fight is the mysterious Dan Moroboshi, secretly an alien from the Land of Light in Nebula M-78, who transforms into his true form in times of crisis, Ultraseven.
Rihito, a dancer who has just returned to Japan, joins forces with his childhood friends Haru, Noah, Eugene, Ray, and Dan to save his best friend, Simon, who has been diagnosed with a brain tumor with only three months to live. Rihito and his five best friends work together to somehow earn money for the surgery to save Simon's life!
In the not so distant future, about 30,000 clones, also known as "The Secret Children," live harmoniously with the humans who created them more than 30 years ago. However, the lives of clones drastically change when a dictator named Bloomquist takes over the presidency and leads a campaign to extinguish them. The new regime instates a Clone Monitoring Committee to fulfill its goal to eradicate the clones until they are all destroyed.
