Enjoy this world.

Story of a team of characters, who defeats out-of-this-world creatures by analyzing their true names. The obsession on finding the true name of friends and foes seems to be a novel concept, but what I find to be the deepest part about this series is its treatment of this world, how humans relates to gods and desires and so forth. It's quite deep if you really want to look into it (and follow the many lengthy dialogs). For those who don't like to think too much, the quality animation in many of the battle scenes also makes this worthwhile. Definitely a series worth watching.
