Kuiba: Shiwanhuoji

A powerful being known as Kuiba is reborn every 333 years and brings total destruction. To prevent this, deities and humans work together to kill Kuiba before he fully awakens. In 1664, Kuiba evades death and takes over the body of a child named Manji. As Manji grows, he develops a strong ambition to become a great warrior. When he learns that Earth’s armies are seeking fighters to battle Kuiba, he and his master join the effort. Unbeknownst to him, the enemy he seeks to defeat is the same being he has become.
