An anime-original spin-off/sequel based on the Saint Seiya series: The god of war and guardian of his namesake planet, Mars, was once sealed away by Seiya, but time has passed and his revival is at hand. Meanwhile, Saori Kido is raising the boy Kouga, whose life Seiya saved, and he's been training every day to become a Saint in order to prepare for the coming crisis. Unaware of his destiny, when Kouga awakens to the power of his Cosmo hidden inside him, the curtain will rise upon the legend of a new Saint.

"Exactly one year ago, aliens invaded Earth. But it wasn't the kind of invasion you'd expect. After descending from space and destroying any opposition, the giant spaceship known as The Bell just... sat there. For a year it's been floating silently over the ocean, quietly observing how Earthlings live. Everyone's pretty much used to it by now.

Everyone, that is, except the Magic User's Club. They're a small band of misfits who can do actual, honesttogoodness magic!
