Synopsis

Back during the Edo Period, three mysterious capsules fell from space. Worried they'd cause disaster, people at the time buried all three and gave the Kamui family a map showing where to find them. Fast forward to today—these capsules are starting to wake up one by one. The first to activate is Tri-Zenon, a guardian mecha that's now piloted by Akira Kamui (whose family has been protecting the secret all this time), his brother Ai, and their friend Kanna. When aliens show up on Earth with their own agenda, they're going to run straight into Tri-Zenon.
