She worked as a 'mom' at an 'orphanage', which was really a farm to feed demons, and the crops were the children she raised. She knew this, but tried to make sure the children didn't know and wouldn't escape. She wanted to give them the happiest lives they could have before they were harvested. She genuinely cares for all the children, and it hurts her to know they'll never live past the age of 12, but she hides it well. She's a good liar. She tries hard to keep the secret and children safe.
