One day Mikuni's mother couldn't fight her jealousy any longer and she tried to kill Misono. However, Mikuni killed her before she is able to harm his little brother. Misono just walked into the room, when he saw the scenario, leaving him traumatized at the sight. After Mikuni and his Servamp, Doubt Doubt, left the house, Mikado ordered Lily to erase Misono's memories of that scene and manipulate them so that he doesn't know why his brother really left the house. Without these memories of the past, Misono is able to live a happy childhood. Whenever Misono tries to get near to the east wing of their villa, Lily manipulates his thoughts so that Misono forgets where he wanted to go. All of the employees in the Alicein household are forbidden to talk about Mikuni, and Mikado pretends that Misono is his first and only son, though Misono does know about the existence of his elder brother.
