"No one can serve two masters."

Masterless

Kane Madison is an architect working in Los Angeles while his doppelganger-like spirit, an eighteenth century Ronin, wanders a parallel netherworld of masked demons and Japanese swordsmen. When tragedy strikes, Kane embarks on a journey of faith which prompts the Ronin to seek out his true master in the spirit world... both will face many battles along their interweaving roads to peace.
