Pygmalio

Synopsis

A tale of love in all forms: pure like a child's, twisted like that of a scorned, lonely woman, and multi-faceted in between. Kurt, the prince of a faraway kingdom, leaves home to find a way to heal his petrified goddess-mother. Battling numerous monsters, overcoming challenges set forth by Medusa's apostles, and helping other people all seem so heavy for a ten-year-old boy. But never fear, he's not alone. His youngest aunt, a goddess from heaven, his girlfriend collected along the way, his-not-quite-adversary, not-quite-friend, mysterious dark apostle and various others are with him. All are drawn in by his charisma, his will, and his purity. Let's join Kurt, to travel to far, far away lands, to meet interesting people, monsters, gods, and goddesses...and then to kick their asses.
