Serial anime picked up by A.D. Vision for release in the U.S. Story of Ayato Kamina on what is essentially a journey of self-discovery through his own life, through the responsibilities he inherits due to his ability to control the Xephon, and through the semi-deity only really known as Ixtli.
One could say this anime has both shoujo and shounen parts.
RahXephon is quite possibly the finest serial anime I've had the privledge to view.
From RahXephon: An alternate dimension in which time passes six times slower than in the outside world (i.e., one year T-J time is six years real-time). So called because the visual barrier resembles the planet Jupiter.
