Legend of the Dragon

I'm talking about the Legend of the Dragon cartoon.

It's one of the anime style cartoons.

I didn't find it impressive at first, but it really manages to grow on you.

The main characters aren't necessarily the coolest looking the series(strange), but other than that the stories themselves are usually interesting, and there are plenty of twists and turns in the overall storyline to make you want to watch.

Basically the story is about Twin brother and sister, with twin destinies(light and shadow)

The interaction between them can be quite interesting at times, siblings who do care for each other, but are on opposite sides.
