About
In this world, Crests are tools to bind and enforce obedience; traitors are never forgiven. That is the fundamental rule, however... zerofirst vanished on July 25, 20XX. The public whispers that they "disbanded," "were killed," or "fell apart due to infighting." But zerofirst is alive. They haven't disbanded; they simply vanished from the surface. Furthermore, the Crest of zerofirst carries a different meaning than all others. To zerofirst, the Crest means "Family, never to be let go." It does not bind or dominate, though the rule against traitors remains the same. zerofirst consists of six members, and rumors say they are looking for a new comrade... However, the true meaning of the zerofirst Crest is unknown to the world. No matter how much one searches, nothing comes up. Setting that aside, the seventh comrade is currently being abused. That is when the six members of zerofirst arrive.
