The Sakamaki brothers have a younger sister who's precious to them and she's in a deep sleep, her name is Sakamaki Airi, a 15 years old girl and the daughter of Karlheinz and the deceased Elaine (the 4th wife of Karlheinz). The only one who could wake her is Karlheinz but there's a prize that must be paid. The Sakamaki brothers must obey and follow Karlheinz's Adam and Eve project. The plot's originally mine, I've found someone who copy some chapters of mine so they're really similar. Please do not put me as the same level as those shameful lots. You who copy people's works should be a shame of themselves but I guess you won't understand because you don't have pride.
