Laito Sakamaki
Laito is the third son of the Sakamaki brothers and the oldest of the triplets. He was sexually abused by his mother, Cordelia and began seeing her as a lover rather than a mother. When Karlheinz found out about the unusual relationship between them, he locked him in the basement. Later Cordelia went to see him and told him that she was now having sexual relations with someone else and had only been using Laito for pleasure.
