Ninjas are the God of Children's, Essien's, miracle workers. They are half-shadow, half-human, allowing them to slip into hospitals and save the lives of infants and small children with health problems. They only seek to do good and would never attempt to harm any mother or child. They save these children by turning them into shadows and healing them with Essien's power in the shadow realm. They do this remarkably fast, so fast indeed that no one notices that they are gone.
