In the ancient time of the gods, a son of the titans was born: Arion, borne of Demeter and Poseidon, the lord of the sea. After being kidnapped to the realm of the Underworld by Hades, Arion is sent on a mission to destroy Zeus, the lord of the heavens, in retribution for causing his mother's blindness. In his quest, he will gain new friends and face the powers of the gods themselves as he struggles to strike down Zeus and save the one he loves from the evil Apollo.
Arion and Saint Seiya are both wonderful adventurous animes based on the Greco-Roman mythology, with similar animation. I'm glad I found Arion in this website as it is really rare, definitely not a masterpiece, but very entertaining.
I'm recommending Mazinkaiser SKL to the fans of The Lost Canvas and vice versa, not because of plot similarities or theme, but because of the production quality, both of these OVA are wonderfully displayed in bright colors and extremelly well detailed drawings, animation is perfect as well, sound top notch as well, and theres actually some similiarities in the character designs, especially the faces. So if you looking for short top notch anime with high level of production, dive in these, you won't regret it.
