Reideen
High school student Saiga's daily routine is disrupted when his family gets news that his Father's remains have been found after years of being missing near a triangular mountain in Japan that some believe is man-made. A meteor with a strange robotic lifeform falls from the sky and begins to cause destruction. This causes a bracelet from his father's research to activate and merge him with an ancient robot buried in the pyramid that's known as Reideen. Together, they will now help save humanity.
