Subaru, the Cosmo of Wonder! Eden's Mission!

Saint Seiya Omega

Eden wanders through the city drawn by a strange cosmo when he meets the Secondary Pallasite Europa and is saved by Seiya. Inspired by the Gold Saint to look for a reason to fight, Eden pursues Europa who was sent in a mission to kill Koga, but has a hard time fighting the enemy until Subaru unleashes an impressive power that was dormant within him.
