History Recap / TheKindaichiCaseFilesAlchemyMurderCase

* LaxativePrank: As Kindaichi reveals during SummationGathering, the director's water bottles were likely spiked with some laxative to make her reach the toilet in a hurry, allowing the murderer waiting in the ceiling to kill her with the sword that [[AttackTheMouth penetrates through her mouth and [[ImpaledWithExtremePrejudice out the back]] once she's in range.

-->'''Kindaichi''': Root of two? What's that? Some kind of plant?\\

* DeathFromAbove: Upon reaching the toilet, the director hears some noise above her, which causes her to look up... just in time to see the culprit, revealing himself from the ceiling space, [[AttackTheMouth piercing through her mouth and [[ImpaledWithExtremePrejudice out the back with his sword]].

* CampingACrapper: [[DragonLady The director]] is ambushed and murdered in the women's washroom. Given [[ImpaledWithExtremePrejudice the nasty method being employed in the murder]], it also counts as ToiletHorror.

* DragonLady: The director of the treasure-hunting show in this case arc is a Japanese woman with a cold and domineering demeanor, such that she has garnered a nickname "demon dragon", as Reika informs Kindaichi early in the case arc. It gets even worse once it's revealed that she was responsible as the mastermind for [[FrameUp setting Haruka up with fake evidence and have her made out to be a junkie]] that caused her to be DrivenToSuicide for [[{{Greed}} more money for herself]] and shows no remorse for it whatsoever.

* ImpaledWithExtremePrejudice: The [[DragonLady director]] is explicitly shown being murdered this way, as the killer drives the sword that penetrates through her mouth and goes out of the back of her head.

* CrossoverCameo: [[ButtMonkey Saburoumaru]] appears as one of final contestant in a quiz Kindaichi attends in order to meet Reika. [[Manga/DetectiveSchoolQ Q-class members]] also appears in one panel watching the show on TV.

* CrossoverCameo: [[ButtMonkey Saburoumaru]] appears as one of final contestant in a quiz Kindaichi attends in order to be able to go treasure hunting. [[Manga/DetectiveSchoolQ Q-class members]] also appears in one panel watching the show from TV.

Kindachi enters a quiz show, where the winners will be chosen as among participants for the upcoming treasure-hunting expedition on a deserted island. Kindaichi manages to emerge victorious, Reika is among the celebrity guests who are picked for the treasure-hunting quest, and Miyuki works as a part-time assistant director in said expedition, and so all three of them join the production team members for the show at the island, not realizing a serial murder case is already developing and about to materialize.

** Saburoumaru fully expects to be chosen as a winner of the quiz show due to his score being the second lowest in the [[VotedOffTheIsland setting that eliminates only the contestant with the lowest score]] and Kindaichi not appearing to be bright. Unfortunately for him, Kindaichi is a CrouchingMoronHiddenBadass and manages to pull off a DarkHorseVictory, which secures himself as the grand winner of the contest itself while getting ''[[ButtMonkey Saburoumaru]]'' eliminated from the quiz show withal as the result.

'''Miyuki''': This is so humiliating.

** She also privately expresses delight in being involved in a serial murder case, believing that [[ItsAllAboutMe she can use the case in question to play up the appearance of a tragic heroine to prop up her career further]], all the while wishing for the same "incident that happened two years ago" that ruined Haruka's life would happen to Reika because she feels snubbed of the success Reika has garnered.

* TemptingFate: When Haruka found out that the culprit was struggling to pay off college tuition fees due to being TheUnFavorite in his financially-declining foster family, she stepped up to cover the costs at once, saying that she could afford the cost due to being a rising TeenIdol. The culprit, filled with gratitude, promised to repay the money after finishing school. Sadly, the promise would remain unfulfilled forever after Haruka was DrivenToSuicide.

* ReactiveContinuousScream: At one point while Kindaichi tries to remember more significant relevance regarding the layout of the room map within the building where they stay after the serial murder case starts unfolding, [[JumpScare a hand is suddenly placed on his shoulder and causes him to scream]], which frightens the person behind him into screaming in return. Kindaichi turns around and sees Miyuki, who's bringing some tea to him at the moment.

* RemovingTheRival: The manufactured drug use and possession scandal that drove Haruka to suicide originated from a rival TeenIdol and the director wishing to push Haruka out of competition for the starring role in a film said rival TeenIdol also wanted.
* RightBehindMe: While a comedian and the quiz show hostess talk about the ongoing serial murder case after two people have fallen victim to murder, they quickly turn their attention to Reika before talking about her manager, who was once a TeenIdol like Reika is, shortly before Reika's idol-turned-manager turns up and make her presence known.

** The backstory reveals that [[TeenIdol Haruka]] was made out to be a junkie due to fake evidence [[DragonLady the director]] had set up to have her discredited in order to pocket more money for promoting another TeenIdol.

** [[DownplayedTrope Downplayed]] with Reika's idol-turned-manager, who found out about about [[DragonLady the director]]'s plot of having Haruka's reputation ruined to prop up her preferred rival TeenIdol for {{Greed}}, for the director told her there was no evidence for the truth to the plot while giving her AnOfferYouCantRefuse.

* MalevolentMaskedMen: Or, rather, "man". The culprit of this serial murder case, nicknamed "the alchemist" due to the setting being inside a physicist who was obsessed with alchemy, wears a metallic mask that helps to conceal the true identity and wields a sword that is used to commit murders, as shown in a recorded footage captured by a security camera the camera operator set up early in the case arc.

* UnwittingPawn: [[ZigzaggedTrope Zigzagged]]. Reika's idol-turned-manager was actually unaware of the plot to have Haruka [[FrameUp framed as a junkie]] until she asks the director, well after the fact. That being said, the fact that she did nothing to help Haruka until she became DrivenToSuicide and has kept quiet about the truth right up to the present day earns her NoSympathy from the culprit.

** Reika's idol-turned-manager is considered an accomplice in the culprit's belief due to not acting to save Haruka even after discovering the truth, and the culprit makes it clear by reacting to her apology with [[RejectedApology rebuff]].

* DeathByLookingUp: Upon reaching the toilet, the director hears some noise above her, which causes her to look up... just in time to see a sword [[ImpaledWithExtremePrejudice piercing through her mouth and out the back]].

* ClearTheirName: Reika is [[FrameUp framed]] as the culprit in this case arc, and so one of Kindaichi's goals in his investigation is to prove her innocence and find out who really is the culprit.

** The main assistant director is the first person to be murdered in this case. As Kindaichi reveals in TheSummation, the killer had requested help from the main assistant director to ensure that one particular TeenIdol would stay in a specific room, which turns out to have been tampered by the culprit to exact murder and manufacture LockedRoomMystery when the right circumstance arrives. That being said, the main assistant director is on the murderer's hit-list from the beginning anyway, and the potentially incriminating knowledge simply made the main assistant director the first target of choice.

** The rival TeenIdol falls asleep after drinking her given bottled water, not knowing it has sleeping drugs mixed with it. This, in conjunction with the door for her room that no one but the culprit knows has been tampered with, allows the murderer to enter her room, kill her, and facilitate LockedRoomMystery while [[FrameUp framing Reika for it]].
