ErecSia were a short-lived band, active around 1999 or 2000. They only released a self-titled demotape, and were also featured in the omnibus album, V.A. TRIBAL MILLENIUM ARIVALL. After their disbandment, most of the members - Reiha, Ren, Naoto, and Shion - would later move on to ALPHONSTEIN with a similar concept.
