Demon Sacred

A symptom which causes one to physically regress till the point of disappearance. A pharmaceutical company which claims to be researching a cure and the cause for this syndrome.

Demon Sacred had four volumes published in English by Tokyopop, from October 12, 2010 to March 1, 2011, before the company became defunct.
