The Detective is Already Dead (2024)

This work provides examples of:

Action Prologue: The series starts when Siesta and Kimihiko confront Albert Coleman aka Bat when he starts a hijacking of a passenger plane.
Actor Allusion: Back in Lost Judgment, Xanthe Huynh played Kyoko Amasawa, who leads the Mystery Research Club who wanted to jump at the chance to be a detective. She's now playing Siesta, who's an actual detective.
Anachronic Order: The light novels are written out of chronological order, and the anime goes even further in adapting material out of order of the novels. The anime's official Twitter account even had to post a chart showing which light novel volume the material covered in episodes 1 to 6 came from. It also shows what light novels received manga adaptations (Volumes 1 & 2 as of that tweet). After the anime's season finale, the light novel's editor put up his own chart showing how all 12 episodes corresponded to Volumes 1 and 2 of the novels. Is your head spinning yet?
Bait-and-Switch: The anime pulls many false baits, such as Siesta is badly injured and the screen fades to black, or she is seen unconsious whenever Kimizuka isn't nearby, tricking the viewers to think that is how she died, just to see her alive and well again. Not until Episode 9, however. Siesta pulled a Heroic Sacrifice to save Kimizuka, and Hel ate her heart, proving she was gone for good.
Biblical Bad Guy: The true identity of the Tuner known as the Phantom Thief Arsene is Abel, the first victim of murder recorded in the Book of Genesis, who has been reborn hundreds of times and always meets his death being violently killed by another person.
Breakout Character: Surprising as it might be, Siesta was originally planned to be a Posthumous Character soon to be displaced, with the starring role falling on Kimihiko, Natsunagi and Saikawa, but the success of the novel made the author keep making her appear.
The Cameo: Fubuki Shirakami and Matsuri Natsuiro make an appearance as news casters in Episode 3.
Connected All Along: Volume 6 reveals that Siesta's recruitment of Kimihiko on the plane as her assistant was not a coincidence or a random twist of fate, but something she had been planning for a long time. It turns out she's very well-acquainted with him due to having worked with him years ago while she was in disguise as a policewoman named "Gekka Shirogane." In the present day, Kimihiko still wonders where Shirogane is and if he'll ever meet her again, blissfully unaware that the woman in question has been right by his side for years.
Did They or Didn't They?: Volume 3 / Episode 7 shows Siesta getting slightly tipsy from "juice" after having dinner with Kimizuka, and later that night in their hotel room she invites him to sleep in the bed together with her. They have a heartfelt, intimate talk about how much the past 3 years have meant to her before she leans in to touch his face and softly ask if he'd like to try something "not so serious." The scene then fades to black. While Kimizuka insisted in Volume 1 nothing happened, the author of the story has said that he's an Unreliable Narrator due to missing some memories and only Siesta would truly know the truth. In the end, it's up to the reader to decide what happened between them that night (although it's notable that, at least in the anime adaptation, the two have their clothes on when they wake up).
Extra-Long Episode: The first episode is actually two episodes long, with the first half being the meeting on the plane, and the second half being an adventure at Kimi's high school.
Gratuitous Spanish: For some unspecified reason, the original novel in Japanese has a Spanish translation of its title, La detective está muerta,^note as a subtitle. Given that "siesta" is a Spanish word (and a very Spanish concept), maybe this explains it.
Nebulous Evil Organisation: SPES is a criminal organization that has pseudohumans in its ranks. They're also the subject of Siesta's investigations before her death.
Not Allowed to Grow Old: An unusual subversion applied to teenage rather than adult characters. During the series' various chapters and flashbacks, Siesta and Kimihiko are shown in scenes set across a four year range from ages 14 to 18, which should be a world of difference for people at that age, yet their character designs in the anime remain just the same among all the episodes, even down to the clothing.
Refuge in Audacity: In "Attention Passengers: Is There A Detective on Board?", Siesta and Kimihiko get involved in an aircraft hijacking case. The latter lampshades it when he throws the question on whether a private detective was on board as the justification Albert Coleman aka Bat was seeking her out.
Plant Aliens: SPES turns out to be this.
Ship Tease: Loads of it between Siesta and Kimihiko throughout the entire story. They behave Like an Old Married Couple in the tail end of their 3 years adventuring together, and practically form a pseudo-family unit with Alicia in London while investigating SPES there.
- Volume 5 has by far the biggest example of such, when Kimihiko manages to stun Siesta silent during her Suicide by Cop gambit when he tells her he loves her, even though he admits to himself he hasn't quite figured out whether he loves her as a woman or as family or as a friend.
- In Volume 6, which is a prequel story, the reason Siesta took an interest in Kimihiko was because he saw through her metaphorical mask even when she was in perfect disguise in her "Gekka Shirogane" alias working with him and understood how desperately lonely she was, and told her he would break her mask one day. Prior to this, she had been planning to take him on as her assistant because he was the Singularity, but after those words from him, she wanted him as her assistant because she was interested in who he was as a person.
- Volume 9 has a short story called "Who's the Detective's Groom-to-be?" included as a bonus in its initial release that takes place during their second year of adventures together when they were 16 years old. A TV ad for a wedding leads Siesta to ask Kimihiko how he would feel if she were to get married. At first, he doesn't really care (which irritates her) until she begins describing a guy who supposedly proposed to her. Kimi declares he would object to the wedding... completely missing the hint that her description was basically what he would look like in his 20s.
- Volume 11 is even bigger than all previous moments:
  - As Kimihiko and Siesta are waiting at a hotel for clearance to travel to the Mizoev Federation, she appears by his side in a Pimped-Out Dress with fancy accessories and sophisticated makeup. He can't help but outright tell her she's beautiful, which takes her aback for a moment. While they enjoy a drink together to pass the time, they reflect on the fact that they're both 21 years old and that they first met 7 years ago, so they've literally spent 1/3 of their lives together, but Siesta says someday it'll be half, then 2/3, then all of it. The scene ends with Kimi saying he has something to tell her once the case is over, and she promises to wait for that time.
  - When Siesta is battling the Enforcer Ookami to buy Kimihiko some time to find Charlotte in Antarctica, Ookami insults her by telling her that she now allows her whole life to revolve around Kimi and that she has lost what once made her special. This actually serves as a Love Epiphany for her to realize that in actuality, she had already fallen for Kimi the moment she first saw him when she only knew him as Boy K, and she nonchalantly admits to Ookami that she doesn't mind being at a man's beck and call if he's someone she's crazy about.
  - In the volume's epilogue, Kimi asks her if she chose him as her assistant that day in the airplane because he was the Singularity, but she outright tells him the real reason was because it was love at first sight (which the reader already knows is the truth thanks to her earlier scene with Ookami). He's rather stunned to hear that as she walks away with a chuckle.
Shout-Out:
- The story is a Whole-Plot Reference to Gosick, another light novel about an unfortunate Japanese student teaming up with a cooler-headed, fair-haired superhuman detective girl to solve mysteries.
- It is also another Whole-Plot Reference to Aria the Scarlet Ammo, of the same artistic line as Gosick, which also features a legendary detective girl roping the main character along as her sidekick and taking down a criminal organization that employs superhuman members. Aside from this premise, the plane kidnapping in the first volume is a reference to the same in the first volume of Aria, Kimihiko's backstory of losing Siesta echoes Kinji's own of losing his brother, Cerberus is outright a clone of Vlad, the blood bullet used by Siesta in the first episode evokes the Scarlett Ammo, and the whole character of Alicia is basically a semi-parodic copy of Aria herself, all with her name, short height, long pink twin tails, personality, alternate personality taking over, true age higher than she looks, and relation to the leader of the villainous organization (and once the humor goes away, Alicia ends up being ascended to the same main character role Aria plays in her own series).
- Hel is a (barely) gender-flipped version of Ayato Naoi from Angel Beats!, down to the cap, hair, personality, Daddy Issues, mind control abilities, and even the same red light effect on her eyes when she uses her powers. Not coincidentally, Angel Beats is another series where a serene, silver-haired girl with superhuman powers is involved with a supernatural heart transplant that moves the search of the main character.
- Another set of plot points, namely the evil organization creating artificial humans, spreading a memory-affecting drug created from strange lifeforms to control students in a high school, and being in relation with a Human Alien entity capable to be cloned, are both together and separately references to Boogiepop Series, where the Towa organization does all of them. Hel also has elements of Boogiepop itself in her androgyny, cape, and being the alternate personality of a troubled girl, while Nagisa resembles a young Nagi Kirima in looks, role and personality, and again, the appendages used by Bat in the anime are designed similarly to how the 2019 Boogiepop anime portrayed those of Eugene.
- The bioweapon monster is a giant wink to Resident Evil, even having Nemesis' face on a body resembling a huge Licker, not to mention the term "bioweapon" being the same as used in the game. The description of Albert Coleman, a stylish, blond villain able to grow mutated tentacles who works for an evil organization that produces bioweapons, also fits Albert Wesker (the Coleman surname likely coming from another Resident Evil character who worked for the same party, Charles Coleman).
- Kimihiko's house has some weird objects at the background, among them a tribal mask, when the female main character intrudes in his house and wears his clothing. This whole scene makes a subtle reference to Haruaki's house and the introduction of Fear in Cube×Cursed×Curious. Siesta's seven items also echo the cursed items employed by the characters of said series.
Show, Don't Tell: After being shot by Siesta's special bullet, Bat's extended appendage is no longer able to attack her. Years later, Kimihiko visits him in prison with Nagisa, with the hopes that he'd be able to help her find the person her donated heart wanted her to subconsciously meet. He says explaining it would take too long, so simply lunges his appendage at Nagisa, only for it to disappear. It turns out Nagisa's donated heart came from Siesta after she died a year prior, and its subconscious influence on Nagisa wanting to meet someone was none other than Kimihiko himself.
Time Skip: The very end of the first episode jumps ahead three years to the time after Siesta died.
- In the light novels, Volume 7 takes place after a two year time skip, and all of the characters are now adults with the one exception of Yui Saikawa.
Title Drop: At the end of the first episode.
Kimihiko: "Death did us part. The detective... is already dead."
- Happens again near the end of the prequel Volume 6, as Siesta reflects on the death of the previous Ace Detective and Kimihiko's guardian Danny Bryant, whose legacy she now continues.
Siesta: The detective was already dead. But his last wish would never die. I would take on that responsibility and carry it with me.
Wham Episode:
- Episode 2: Siesta's heart was given to Nagisa Natsunagi in a successful transplant operation after she died.
- Episode 9: Alicia turns out to be Hel's Split Personality, and it's revealed how Siesta died - she pulled a Heroic Sacrifice to save Kimizuka.
- Episode 10: Siesta's heart destroyed Hel from within and erased her memories, creating a new identity named Nagisa Natsunagi.
- Episode 11: Siesta takes over Nagisa's body for an amount of time.
What the Hell, Hero?: Upon learning who Nagisa's heart came from, Kimihiko's initial reaction is to play it down and act as though it's no big deal. Nagisa immediately slaps and berates him for belittling the heart's immense desire to reunite and meet someone she didn't know which turned out to be him. He then gives her a Cooldown Hug, and a tearful reunion, to give some closure to Siesta suddenly dying a year earlier.
Whole Episode Flashback: Volume 6 is this with its Framing Device coming from two sources, with the first being Kimihiko telling Nagisa, Charl, and Yui the story of his past with Danny Bryant as his parental guardian, and the second being the Noches android reading Siesta's diary covering the same incident from her perspective when she was hunting down Danny Bryant as a traitor to the Federation Government.
