This Story is happening before the arrival of Kyle the MC. It happened one year before he joined the Heaven Manor academy.
Emea and Emia are twins that look like a doppelganger, they are the reincarnation of the Goddess of Life Emea Kyle's former wife. Having no idea what their true identities are, they joined the Heaven Manor academy to make friends until one day they remembered who they were.
