Dimension W, Vol. 4 — Yuji Iwahara

The ghosts of Yasogami Lake are none other than those who lived there twenty-one years ago, their beings saved inside Dimension W by a powerful "Numbers" Coil! A young Shijuurou Sakaki and the victims of a dam flooding have been interfering with the present from their small slice of eternity. Shijuurou's sister, Marisa Sakaki, holds the key to everything, but a group of criminal Collectors after her secrets throws Hotel Yasogami into chaos. Kyouma and Mira each make their own way to the truth. What dark tragedy has the Numbers Coil kept out of the light for twenty-one long years?
