Back from the Dead

What happens when, during one normal day... it's not just a normal day. an occurrence that happens only once every ten thousand years, takes place. The universe aligns itself with its little-known counterpart, a universe called Shishanouchu, the universe of the dead. This historic alignation results in thirty people being transferred from the alternate universe back to the land of the living. However, the universe of the dead is disastrously fair in its dealings - what happens when fifteen members of the Dark and fifteen of the Light come back to life?
