(W/A) Mokumokuren Two boys grew up together in a certain village-Yoshiki and Hikaru. One day, Yoshiki became sure that Hikaru was no longer himself. He resolved to accept the new 'Hikaru,' whatever happened to his friend. But now he's decided to research the history of 'Nounuki-sama' and Kubitachi to understand what this creature truly is. The situation evolves unpredictably, outside the boys' control. Who will make the next move, and what will they find?

Standing before the horrific leg-lined fissure in Ashidori, ?Hikaru? prepares to step inside as Yoshiki looks on. Will he return safely, or will their plan to close the hole leave ?Hikaru? stranded on the other side? Meanwhile in Udekari, Tanaka and his newly recruited assistant test their own method for sealing away the supernatural. As dangerous as leaving the holes open would be, closing them could prove to be fatal?
