Karas

This is an excellent anime.  Not perverse and albeit violent and bloody, it's palatable.  Well, not sure about the violent parts but I highly recommend this one.  It's only 6 episodes long so I won't give much and I don't suggest Wikipedia (it may ruin it).

The best way to put it is swords and the future with some of the best CGI and art I have seen.  It's not Princess Mononoke level but it is up there.

This is one of the few anime in which my favorite character is the main character.  We shall call him Karas.

I know Hollywood Video has this so rent it there or buy it (your call).
