Hades Project Zeorymer

In a world overshadowed by secretive government agendas, Akitsu Masato's life takes a dramatic turn when he discovers his past has been a carefully constructed illusion. Captured by the clandestine "Last Guardian" project, he learns that his true purpose lies in piloting a formidable mech known as the "Zeorymer of the Heavens." The revelation is jolting, especially when he witnesses his parents exchanging money for his upbringing, shattering his perception of family and identity.

As the Last Guardian readies itself for the resurgence of the Hau Dragon, an organization intent on global domination, the stakes rise. Fifteen years prior, Hau Dragon constructed eight powerful mechs, each embodying a natural force. However, their creator, Kihara Masaki, destroyed all but the leader, Zeorymer, which he then entrusted to the government along with an embryo that grew into Masato himself. With the revival of the remaining mechs looming, Masato and his ally Himuro must step into their roles as pilots. Yet, both harbor secrets that could change the course of their battle against Hau Dragon, revealing a deeper connection to their shared destiny.
