Nabari No Ou Vol. 13
Like her son, Asahi Rokujou was once the king of the Hidden World. And ten years ago, a torrent of greed and madness surged through the shinobi realm, with her at the center of chaos. But the memories of the events that came to pass on that one fateful day vanished from the minds of all involved. However, one man - Tobari Durendal Kumohira - retains what was forgotten a decade earlier...The cruel truth he finally shares with Miharu will be the last step on the stairway the king must ascend to assume his throne.
