Plot
MazinSaga tells the story of the young Koji Kabuto, a university student who finds a strange helmet that is the fruit of his late father's research. The helmet, named Z, also called the Armor of God, reacts to its user's will and spirit. When Koji wears it, the overwhelming power of Z causes it to violently destroy everything on Earth. After the armageddon, Koji is contacted by the spirit of his father who frees him from Z's influence. Waking up on a colonized Mars after being teleported by Z, Koji encounters Sayaka Yumi who tells him of the problems the colonies are facing. Koji decides to fight with Z to protect the colonies from several threats including the evil God Kaiser Hell.
