After a devastating earthquake that left most of Japan in ruins, the
district ward of Shinjuku in Tokyo has opened up a doorway into
another dimension -- becoming the halfway-house suspended between the
mortal world and the supernatural. It has become a place where the
living fight a losing battle with monsters and demons from the
netherworld -- a constant struggle for control on grounds which
inevitably may plunge into the depths of Hell.
Factory manager by day and moonlighting P.I. by night, Setsura Aki is
no stranger to danger. Specializing in missing-persons cases and
considered the best "man hunter" in the business, he allies himself
with friend and rival, Doctor Mephisto, a wizard of physical and
spiritual surgery. Together in battle, there is none that can compete
with their combined wit and power -- until now. Coming from the
deepest and darkest parts of China, four immortal vampires, led by one
of unmatched beauty who goes by the ubiquitous title "Princess,"
mystically sail into landlocked Shinjuku aboard an ancient ghost ship.
She and her ancient undead entourage with powers never before seen of
vampires, have surmounted four thousand years of space and time to
seize control of Shinjuku and make it their own. It is up to Setsura
and Mephisto to uncover their new formidable foes' true origins and to
reveal the truth behind the Princess's dark plans for the city.
