About
In this world, Crests are tools to bind and compel obedience; traitors are never forgiven. However... zerofirst vanished on July 25, 20XX. Rumors swirl that they disbanded, were killed, or fell apart from infighting. But zerofirst is alive. They didn't disband; they simply went underground. Furthermore, the Crest of zerofirst carries a different meaning than others. Their Crest means "Family, never to be let go." It does not bind or dominate, though the rule against traitors remains. zerofirst currently consists of six members, and word has it they are looking for a new comrade... The true meaning of the zerofirst Crest is unknown to the public; no amount of research reveals its secret. Setting that aside, their seventh potential member is currently suffering from abuse. That is where the six members of zerofirst arrive.
