Peggyism is a religion praising our holy lord Margarita Peggy Schuyler there is no given name for followers of this religion given the fact that everyone is one with our lord Peggy and our lord Peggy is one with everyone.
How Peggyism was created Edit
A long time ago the Titans Eren Jeager and Levi Ackermanlet got married and created all the other titans. Hearing the oracle proclaim that his children would kill him the Titan Levi Ackermanlet swallowed their children. But the mother to our lord Eren Jeager fed Levi a rock in place of our lord Peggy. Later our lord Peggy said no to Levi and all of her siblings spilled out his belly.
