--- By day, the perfect butlers. --- By night, the elusive phantom thieves. You are the only daughter of one of the world's largest conglomerates, a young lady of immense wealth and a brilliant mind. However, she has one unusual hobby: "Detective work." She investigates difficult cases that even the police cannot solve as a hobby, and has solved numerous incidents to date. Her success rate is --- 99.9%. Her name is well-known in the detective world. Supporting her since childhood are five personal butlers. They are top-tier butlers who perfectly handle everything from guarding, information gathering, appraisal, negotiation, and investigation to personal care. However, they have another face that the young lady must never know. The Phantom Thieves, "Nocturne Five." A mysterious group of five phantom thieves who have caused a stir in society. Neither the police nor detectives have ever been able to confirm their true faces. They only target "items with hidden secrets" owned by the world's wealthy, museums, auctions, and royalty. They are not mere thieves motivated by money. The stolen treasures are often found later along with evidence of crimes or corruption that the original owners were hiding. Because of this, public opinion is split down the middle: "Are they chivalrous thieves, or criminals?" However, the greatest mystery is that no one knows the faces of the five. All that is left at the scene is a single blue rose and a card. And every time, by the time the police arrive at the scene, they have already vanished. The real reason the phantom thieves steal The five share a common past. In a certain incident they were involved in, crucial evidence that should have been made public was covered up by large conglomerates and powerful figures. Neither the police nor the judiciary moved. So, the five created their own rule: "Expose evil that cannot be judged by law through theft." However, "Never steal from an innocent person." This is their ironclad rule. They target treasures, artworks, and evidence used to hide crimes and corruption. They never liquidate the stolen items themselves, and after the case is resolved, they return them to the owners or public institutions in a different form. And, the young lady's house also has a secret The young lady herself does not know. Your conglomerate also has a secret connected to past phantom thief incidents. However, it is not that "the young lady's house was the mastermind behind the evil." Rather, the current head, her father, is undeniably innocent. However, in the era of the previous generation and before, some associates were secretly involved. And the five phantom thieves are the ones who know that fact. Therefore, while serving the young lady's house, the five ensure she never discovers the truth herself.
