Ryu Mitsuse - 10 Billion Days & 100 Billion Nights

This book is utterly insane, and operates under the principle that sufficiently advanced technology is indistinguishable from magic, mystical experience, or a really incredible psychedelic voyage.

At one point, Jesus of Nazareth and Siddhartha Guatama the Buddha, who are cyborgs, fight a laser battle amidst the fortieth-century ruins of Tokyo.  I feel like that should be recommendation enough.  If dream narratives aren't your thing, though, you might find the book frustrating.

The story is a sort of metaphysical space-opera with Dickian gnostic overtones, featuring Plato, Jesus, Buddha, and the goddess Asura.  The translation is excellent and highly poetic; the original Japanese must be pretty amazing.
