Muteki Ou Tri-Zenon

During the Edo Period, three mysterious space capsules fell to Earth. Fearing they might bring chaos, the people of that time buried the three objects underground and entrusted a descriptive map to the Kamui family. Today, those three objects have awakened one by one. The first to awaken, Tri-Zenon, one of the Zenon Guardians, is now piloted by Akira Kamui, descendant of the Kamui family, along with his brother Ai Kamui and his friend Kanna. Aliens who come to Earth with a purpose must now face Tri-Zenon.
