There is a world called Sheol between this world and the other world. There stands a church of light with a church of darkness underground, Clepsydra. One day, a girl, Eve, strays into the church. She doesn't know who she is and why she is there, but she gradually becomes friends with other residents. A while later, a deader appears in the church and the last judgement is about to take place. Using her ability, she reads the deader's mind and reveals his secret. Will Eve be able to lead the deader's soul to heaven...?
