Plot

A war between five races for supremacy on Earth is won by humanity, led by the hero Sid. Suddenly, history gets overwritten so that Sid never existed, leading to humanity losing and becoming subjugated by the other races. All of this is witnessed by a boy named Kai, who is mysteriously unaffected by the alterations. In this new world, Kai finds that he never existed previously, so no one knows him. After meeting a mysterious girl named Rinne, Kai is inspired to become the hero himself and free humanity.
