Blood and Reversed Souls (Corpse Party Fanfic)

Sequel to Shadows and Despair!

Have you ever imagined if you traded your life to a dead person? You have to be in their place, just a wandering ghost, suffering that person's agony. Now, imagine the dead person turning into a live one. The momentary confusion, but then the sudden outbreak of happiness. Probably not the best thing to do, though.
But nine friends have no choice in this doing. Sachiko strikes again, having the dead students from Kisuragi Academy coming back to life. Yet, that is not all. The alive are becoming dead, left to suffer at Heavenly Host.
Try to wrap your head around this story as you see what happens after the game version of Corpse Party...
