It was originally the solo project of GPK (Gothique Prince Ken), while Kiwamu (of Blood) joined later that year.

They were featured in several publications including Cure Magazine and they have toured Australia, Japan, the United States, Europe and Central America.

This was followed a month later by their "Lament of the Fallen Star Tour" which included shows in Japan, Mexico, Costa Rica and in the United States[1] at Nekocon.

GPKism's first full-length album, Atheos, was released on March 4, 2009 with the concept "Lament of a Fallen Angel".
