Misono is born as the son of Mikado Alicein and Mikuni's teacher who were having an affair. In his first years he was raised by his mother until she was murdered by Mikuni's mother out of jealousy. While Mikuni's mother killed his mother, she didn't kill him because she knew that Misono has done nothing wrong, so she and her husband decided to take care of Mikuni as their own son as atonement for the murder. Misono soon became close with his older brother, both often played together. Mikado and his wife wanted to love Misono just as they loved their other son, but Mikuni's mother wasn't able to. She tried to hide it, but deep inside she felt jealousy towards Misono as well.
