Premise
Ever since he was a child, Kimihiko Kimizuka has attracted trouble. According to him, he was born with a condition that naturally attracts him to troublesome situations, such as being forced to join a flash mob while taking a leisurely walk, accidentally stumbling across an underworld transaction between drug dealers, and being at the site of crime scenes often enough to sometimes be considered a suspect.
One particular day in his third year of junior high, he was kidnapped and forced to carry a suitcase onto an international flight; on that flight, he met Siesta, a beautiful young woman who proclaims herself to be a "legendary detective". Forcefully made into her sidekick, Kimihiko helped her stop the plane from being hijacked, but not before Kimihiko discovered the existence of underworld organizations. After being constantly pestered, Kimihiko agrees to be Siesta's sidekick and for three years, they worked together, finding and solving an innumerable number of cases.
Now in his last year of senior high, Kimihiko is once again confronted by the ghosts of the past as he tries to solve new cases that fall into his lap. He is extremely bothered by the fact that he is called a detective; after all, the detective is already dead.
Characters
- Kimihiko Kimizuka (君塚 君彦)
- An 18-year-old high school student with a talent to attract criminals so that in his past he often witnessed various crimes and was even later questioned by the police as a suspect himself. This talent, which he himself calls a "trouble magnet", apparently also led to his encounter with the master detective Siesta, who wanted to recruit him as her assistant, which he initially refused due to his characteristic of always ending up in unpleasant situations. Author Nigojū initially planned to give him the alias "Kurokage" when creating the series of novels.[2]
- Siesta (シエスタ)
- A mysterious and beautiful young woman and self-proclaimed "master detective" who owns a musket and seven items with magical abilities. Her motto is to solve criminal cases before they happen. Until her death, Siesta was a member of the Twelve Tuners, an organization of twelve people who want to save the world from chaos. Originally, Siesta was just a minor character in the series. After Nigojūs manuscript won the top prize in the MF Bunko Newcomer Award, she eventually became one of the main characters in the novel series.[2]
- Nagisa Natsunagi (夏凪 渚)
- An 18-year-old high school student. She has a strong and dominant personality. As a child, she suffered from a heart defect and was forced to stay in the hospital bed because of it. A year before the actual plot began, she received a donor heart from an unknown donor. Originally, according to the author's plans, Nagisa was to become the only main protagonist of the novel series.[2]
- Yui Saikawa (斎川 唯)
- A middle school girl who is already a successful idol at the age of 14 and regularly appears in magazines or commercials. She hires Kimihiko and Nagisa to protect her and an heirloom from a thief. Although Yui is the youngest character in the novel series at 14, she is considered the most adult character. Originally, Nigojū planned in his manuscript to put Yui in the role of the detective, but later changed this.[2]
- Charlotte Arisaka Anderson (シャーロット・有坂・アンダーソン)
- A 17-year-old assassin who was originally set to assassinate Siesta. However, after losing a fight against Siesta, Charlotte began to idolize her. She is half-Japanese and was born in the United States. She becomes an assistant to Fūbi Kase.
- Hel (ヘル)
- Hel was Alicia's alter ego, who now "lives" in Nagisa's body. She was Siesta's archenemy. To save Alicia's life, Siesta sacrificed her own life, but after her death has the ability to take control of Hel's consciousness and suppress her evil side.[3] Hel was known to "devour human hearts".
- Fūbi Kase (加瀬 風靡)
- [4]
- A senior police officer who has met Kimihiko several times. Because of his talent for being in the wrong place, she is particularly skeptical of him.
- Chameleon (カメレオン)
- A member of the secret organization SPES. He has the ability to transform into a chameleon, hence the name. In his human form he has white hair and purple eyes. In his chameleon form he is much larger, has sharp teeth and takes on a fearsome appearance.
- Bat (コウモリ)
- Bat is a former antagonist of the series. He was a member of the secret organization SPES and was behind the plane hijacking, but was confronted by Siesta and Kimihiko and defeated in a fight. Bat is a liar and a coward who only acts on his own whim.
- Cerberus (ケルベロス)
- A member of the secret organization SPES and is an android, who also has genes of a Kerberos and a werewolf. He is Hel's guardian. Like Chameleon, he also has the ability to assume another form - that of a werewolf. He is smart, but follows his primitive instincts.
- Alicia (アリシア)
- A girl with pink hair, which is tied into two ponytails. She wears a dress that is similar to Alice, the title character from the novel Alice's Adventures in Wonderland by Lewis Carroll.
Production
The idea of The Detective Is Already Dead started from a random sentence the author, Nigojū, thought of one day. The sentence was "Is there a detective on the plane?", and later became the first sentence of the story.[5]
