About
In this world, crests are used to bind and force obedience, and traitors are never forgiven. 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 sight. Furthermore, the meaning of Zerofirst's crest is different from others. Zerofirst's crest means "family, never letting go." It doesn't bind or dominate. While they still don't forgive traitors, Zerofirst is a six-member group currently rumored to be looking for a new comrade... The true meaning of Zerofirst's crest is unknown to the public. No matter how much you search, nothing comes up. Setting that aside, the seventh member is currently being abused. That is when the six members of Zerofirst arrive.
