Taiyô no ko Esuteban

I watched this back in the early 90s when I was quite young and wow what a great series it was. An interesting storyline, it tells the story of a boy named Esteban who is renowned in Barcelona during the 1500s for being a child of the sun and having strange powers. He is then looking for the Mysterious Cities of Gold along with another child (an Inca girl named Zia) who also has the same medallion as him, both having a supernatural connection. Other characters include a boy from South America named Tao as well people from the old world Mendoza and co who are interested in seeking the cities.

The series was a great childhood anime as there are memorable characters and the storyline offers a philosophical and paranormal touch entwined with a balance of history. The MCOG is an anime that was very unique and it's a shame that there are no others like it today.
