The infant girl, Kaede, is abandoned in a forest by her father. Upon hearing the news of her abandonment, her mother starts an unrelenting quest to find her daughter again. The infant is taken in by the local Child Welfare Agency, an orphanage maintained in that area.
The child, Kaede, becomes a frequent target of bullying and cruel comments, to the point that she emotionally shuts herself down. This does not stop some other people from trying to get a rise out of her. She is also treated dismissively and with contempt by the orphanage teachers and staff members. She is seen with her horns in a class photo.
Presumably, early childhood meetings between Kouta and Yuka take place about this time.
Unknown fates of Kouta and Kanae's mother, Yuka's father, and Mayu's biological father take place.
