Kuiba
Every 333 years, a creature is born again in this strange world. This thing is a Kuiba. The creature is made possible by a mistake in the way the Universe works. Every time it shows up, it makes things worse for everyone. Every 333 years, gods and people from all over the world work together to kill Kuiba and keep it from coming back. This is called "The Revival of Kuiba." In 1664, when Kuiba was reborn, the attempt to kill him failed because he was able to move into Manji's body. Manji is a young boy who doesn't know that Kuiba lives inside him. Since the plan to kill Kuiba didn't work, the people of Earth are building an army to fight him. Manji and his Master want to show how good warriors they are, so they join the army to fight Kuiba. Manji and Master Man meet a number of interesting people as they get ready to fight Kuiba. They also meet a beast that will show them if they are ready for the challenges that lie ahead.
